Growing Brussels Sprouts - Ep. 209

Growing Brussels Sprouts - Ep. 209

Back on episode 200, the Ask Me Anything episode, someone asked if I would do an episode on growing Brussels sprouts. I said no at the time because I hadn’t yet successfully grown them but indicated it may be soon because Brussels were having a moment in my garden this spring and it was looking good.

Well, here we are and we’re talking Brussels because I managed to successfully grow and harvest a summer crop from a spring planting and have round two of seedlings started already for planting soon for a fall harvest.

So, today on Just Grow Something, we’re talking Brussels sprouts! The background of the plant, how to grow it, what pests and disease plague it, and how to harvest and store. It’s a full blown crop specific episode that will hopefully demystify growing these teeny cabbage look-a-likes in your own garden. Let’s dig in!

00:00:00
OK so back on episode 200 the Ask me anything episode, someone

00:00:05
asked if I would do an episode on growing Brussels sprouts.

00:00:10
How many times can I say episode in one sentence?

00:00:13
I said no at the time because I hadn't yet successfully grown

00:00:19
them, but I indicated that it may be soon because Brussels

00:00:22
were absolutely having a moment in my garden this spring and it

00:00:25
was looking good. Well, here we are and we are

00:00:28
talking Brussels sprouts because I managed to successfully grow

00:00:32
and harvest a summer crop from a spring planting and I have round

00:00:37
two of seedlings started already for planting soon for a fall

00:00:42
harvest. So today on Just grow something,

00:00:44
we're talking Brussels sprouts, the background of the plant, how

00:00:47
to grow it, what pests and disease plague it and how to

00:00:51
harvest and store. It's a full blown crop specific

00:00:54
episode that will hopefully demystify growing these teeny

00:00:57
tiny cabbage. Look alikes in your own garden.

00:01:01
Let's dig in. Hey, I'm Karen, I started

00:01:04
gardening in a small corner of my suburban backyard and now 18

00:01:07
years later, I've got a degree in horticulture and operate a 40

00:01:10
acre market farm. I believe there is power or in

00:01:13
food and that everyone should know how to grow at least a

00:01:15
little bit of their own. On this podcast I share evidence

00:01:19
based techniques to help you plant, grow, harvest and store

00:01:22
all your family's favorites. Consider me your friend in the

00:01:25
garden. So grab your garden journal and

00:01:27
a cup of coffee and get ready to just grow something.

00:01:40
Thank you for joining me this week.

00:01:41
If you are new here, I am your host, Karen Velez.

00:01:44
I am glad that you are here for all my junior gardeners.

00:01:47
I am glad that you are listening alongside mom or dad or grandma

00:01:50
or grandpa or whoever it is that is greasing your ear holes with

00:01:53
my voice today. I am very glad that you guys are

00:01:56
all here. If you are new to the podcast, I

00:02:01
have all kinds of other resources over on my website,

00:02:04
justgrowsomethingpodcast.com. You can find articles and you

00:02:08
can sign up for the newsletter and all kinds of other stuff

00:02:11
over there. I've also got a YouTube channel

00:02:13
that feeds onto that website as well.

00:02:17
So Brussels sprouts. Brussels sprouts are a member of

00:02:22
the Brassica family, which means that they are very closely

00:02:25
related to cabbage and broccoli and kale.

00:02:30
They are small leafy green vegetables that look like

00:02:36
miniature little cabbage that grow on stalks and they are

00:02:41
either totally prized for the unique flavor that they give off

00:02:46
or they are totally despised by people who were forced to eat

00:02:50
them in maybe just a boiled, you know, manner or whatever and

00:02:54
never really was treated to Brussels sprouts that were

00:02:58
cooked the proper way. I know a lot of people that

00:03:01
absolutely refuse to touch Brussels sprouts because they

00:03:04
were just served boiled sprouts. And trust me when I say I had

00:03:10
zero desire to eat Brussels sprouts until somebody cooked

00:03:12
them for me the proper way. So this is not going to be a

00:03:15
cooking show, but I'm just telling you, if you can find a

00:03:18
really good recipe, go for it because you would be very, very

00:03:22
surprised. If you like cabbage or anything

00:03:25
sort of in that cabbagey family, you will like Brussels sprouts.

00:03:28
You just got to cook them the right way, OK?

00:03:31
Brussels sprouts are native to the Mediterranean and were

00:03:36
cultivated as early as the 13th century.

00:03:39
They gained their name from the city of Brussels, which is why

00:03:42
they are Brussels sprouts with an S Brussels sprouts, not

00:03:47
Brussels sprouts. It sort of blends together when

00:03:50
we say it, but that's what happens because that is where

00:03:52
they became popular in the 16th century.

00:03:56
They are believed to have been selectively bred from wild kale

00:04:04
plants or wild cabbage plants, which essentially is how we got

00:04:08
all of our brassicas. Everything that we eat that's in

00:04:11
the Brassica family, kale and cabbage and cauliflower and

00:04:15
broccoli and Brussels sprouts all kind of started in the same

00:04:20
space. They were what we would view as

00:04:23
being a wild kale. They weren't a a head developing

00:04:26
type of a plant. And different cultures kind of

00:04:30
took that plant and cultivated them, selecting for the

00:04:34
characteristics that they preferred, Whether it was

00:04:37
forming a head or if it was forming a flower or it was

00:04:41
forming a stalk that had the little tiny heads on it,

00:04:43
whatever it is, or just remaining in a leafy form.

00:04:46
So that's how we have all these different versions of our

00:04:50
brassicas, but they all kind of started with the same wild

00:04:53
plant. And actually the first written

00:04:55
records of Brussels sprouts appear in the 16th century.

00:04:59
And of course, historically they were not just used as a food

00:05:02
source, but they were also valued for their medicinal

00:05:06
properties because they are very rich in vitamins and minerals.

00:05:09
So they were used to sort of boost the immune system and

00:05:11
support people's overall health. Nutritionally, Brussels sprouts

00:05:16
really are a sort of powerhouse. 1/2 cup serving has 28 calories.

00:05:23
It's got less than, you know, a half a gram of fat, about 16

00:05:28
milligrams of sodium, 5 1/2 grams of carbs, just about 2G of

00:05:33
protein and 2G of fiber, which is very notable because that's

00:05:38
about 7% or so of our daily value that we're supposed to get

00:05:44
in fiber every day. And that's from 1/2 cup serving.

00:05:47
So they are very rich in vitamins, particularly vitamin K

00:05:51
and vitamin C. They are a good source of

00:05:53
manganese and potassium and folate.

00:05:57
This that fiber, that dietary fiber they contain helps to

00:06:00
promote digestive health. And they also contain some very

00:06:03
beneficial antioxidants compounds like camphorol and

00:06:06
flavonoids and polyphenols. These are all known to be

00:06:10
anti-inflammatory and anti anti oxidant.

00:06:13
Now of course if you have stomach sensitivities or IBS or

00:06:18
anything that requires a low fiber diet, then Brussels

00:06:23
sprouts may not be the veggie for you.

00:06:26
They are in the cabbage family and those cruciferous vegetables

00:06:30
are notorious for causing stomach upset and that is partly

00:06:35
from that high fiber content. So if you are new to Brussels

00:06:39
sprouts, let's just start your culinary journey with a little

00:06:43
bit of caution. Now what I have found is that

00:06:48
growing Brussels sprouts requires patient and some very

00:06:53
specific care. This year was not my first year

00:06:56
attempting to grow Brussels sprouts.

00:06:59
I have planted them in the spring multiple times and I have

00:07:03
attempted them in the fall a couple of times and neither of

00:07:07
which did I have very good success.

00:07:09
So I was really excited this year to see that they were

00:07:13
developing beautifully and realized at that point that I

00:07:18
had no idea what I was supposed to do with them after they

00:07:21
started to develop. So we'll get into the harvesting

00:07:24
techniques here in a little bit. But what I have figured out is

00:07:28
that the planting time definitely matters, The moisture

00:07:32
level definitely matters, and the temperature, right?

00:07:36
So the first thing that we want to do with Brussels sprouts is

00:07:39
make sure that we're choosing the right variety, something

00:07:42
that suits your climate and your growing conditions.

00:07:47
Shorter plants tend to mature earlier and tend to be more cold

00:07:52
tolerant. So if you are in a short season

00:07:54
area, this may be helpful for you in getting a crop to

00:07:59
maturity. Or if you are in a much warmer

00:08:04
southern climate here in the Northern hemisphere with a very

00:08:07
short window of cool weather, that can also be very helpful.

00:08:12
So some of the really popular varieties are Jade Cross.

00:08:16
This one is fairly early maturing.

00:08:18
It is very disease resistant. It is also fairly heat tolerant.

00:08:22
It matures in about 95 days from transplant.

00:08:25
There is Long Island improved. This is a heirloom variety.

00:08:29
It is known for its very large sprouts.

00:08:32
It takes a bit longer. It's around a 90 to 100 days

00:08:36
maturity from transplants. Diablo is one that is also very

00:08:41
cold Hardy and is supposed to produce very high yields, but it

00:08:44
takes the longest. It's about 110 days to maturity.

00:08:48
So you really do need a long, cool growing season for this

00:08:51
one. What I opted for was Dagon and

00:08:56
it's a mid season variety, so it's sort of, you know, in the

00:09:01
middle of the number number of days to maturity.

00:09:04
But it has a tendency to hold well in the field.

00:09:07
And to me this meant I could have something that I could

00:09:10
plant in both the spring and in the summer for a fall harvest.

00:09:14
So here we are. That's the variety that I'm

00:09:16
growing, and it tends to mature in about 100 days from

00:09:20
transplant. The reason that, you know,

00:09:24
Brussels sprouts are so temperamental is because they

00:09:26
thrive in that cooler weather, which is very typical for our

00:09:31
brassicas. And so that's why Brussels

00:09:34
sprouts are technically usually planted in the late summer for a

00:09:37
fall harvest. That's why they tend to be, you

00:09:40
know, more of a plant that we see used as a side dish for

00:09:45
like, our fall and winter holidays, right, Thanksgiving

00:09:48
and Christmas, that sort of thing.

00:09:49
They require a very long growing season.

00:09:51
Most of them are, you know, maybe the fastest ones I've seen

00:09:55
are about 80 days all the way up to 120 days from transplanting

00:10:00
to maturity. Now, if you live in a warmer

00:10:04
climate that doesn't get a whole bunch of super deep freezes over

00:10:08
the winter time, you can actually plant them in the late

00:10:12
winter for an early spring harvest.

00:10:17
I planted in spring this year like I said, and then I have

00:10:22
started plants already and have those plants getting ready to go

00:10:28
in probably here in the next week or so.

00:10:30
Usually my fall brassicas are going in last week of July,

00:10:34
maybe the first week of August. It all depends on what the

00:10:36
temperatures are doing and with the intention of having them

00:10:40
ready to harvest for those, you know, fall, maybe early winter

00:10:44
time frame. So when you are figuring out

00:10:48
where to plant your Brussels in the garden, we're talking full

00:10:52
sun exposure. So at least six hours of direct

00:10:56
sunlight per day. Again, this can be broken up.

00:10:59
We've talked about this before just because you only get, you

00:11:02
know, a few hours in the morning and then there's a break in the

00:11:04
afternoon. If you get a couple more hours

00:11:06
in the evening then that counts as your six hours, preferably 8.

00:11:12
I've seen with most of the brass because they really do prefer

00:11:15
closer to that 8 hours. But if all you have is 6 hours,

00:11:17
it's fine. They will get there, they're

00:11:20
just going to take longer to get to maturity.

00:11:23
You also want to make sure that the soil is well draining.

00:11:26
It does like the water, it doesn't like standing in the

00:11:29
water so rich and organic matter.

00:11:32
And then they've got a really wide ideal soil pH, anything

00:11:35
from six point O to 7.5. So if you have an area that's a

00:11:37
little bit more alkaline, they will grow just fine.

00:11:41
As a matter of fact, the field that these are planted in this

00:11:44
year actually is on the alkaline side.

00:11:46
I think I was sitting at about 7.2 the last time I checked and

00:11:49
they have done absolutely beautifully.

00:11:52
So of course it's always a really good idea to incorporate

00:11:54
compost or some well rotted rotted manure just to improve

00:11:58
that fertility and to help the drainage.

00:12:01
Just like all the other brassicas, they can be heavy

00:12:03
feeders. So if you need to boost your

00:12:07
soil fertility, you just want to do a sort of balanced fertilizer

00:12:12
like a 10/10/10 that can be added at the beginning in order

00:12:17
to be able to sort of boost that that soil fertility.

00:12:22
But keep in mind that they will benefit from a good amount of

00:12:27
nitrogen just like our other brassicas.

00:12:29
So you could also add something like a blood meal or a fish

00:12:32
emulsion that can be beneficial. But per usual, make sure you're

00:12:37
doing a soil test and you're just not adding these things

00:12:39
Willy nilly into your soil or into your raised containers.

00:12:44
Now, you can grow Brussels sprouts in pots.

00:12:49
I mean, of course you can grow them in your raised planters.

00:12:52
That's fine. They will do just fine.

00:12:53
You want to make sure they're at least about a foot to 18 inches

00:12:57
deep. But you can actually do these

00:12:59
like in a pot on your patio. And these are actually very

00:13:03
beneficial because if it's you're growing in a small space,

00:13:07
they grow vertically on their own just naturally, and you can

00:13:10
harvest off of them pretty continuously.

00:13:13
So you just want to make sure that you have a pot that is at

00:13:15
least 12 to 14 inches in diameter, again, 12 to 18 inches

00:13:20
deep because Brussels sprouts do have a pretty substantial root

00:13:23
system and they're going to need that space to grow and to be

00:13:27
able to feed that green growth. Just make sure that the pot has,

00:13:31
you know, significant drainage because we don't want those, you

00:13:34
know, roots to get water logged. And then just use a high quality

00:13:38
potting soil, something that's rich in organic matter.

00:13:40
Make sure that it's well draining as usual.

00:13:43
I'm going to caution when you're doing containers, do not use

00:13:46
garden soil. That can be too heavy.

00:13:48
It's going to get compacted into those containers.

00:13:50
It's going to be very difficult for those roots to move through

00:13:54
the pot. So make sure that you are using

00:13:56
a potting mix. If you can amend that potting

00:13:59
mix with some compost or again, some well rotted manure, that's

00:14:02
going to provide some of those essential nutrients.

00:14:05
It's always a good idea when you are growing in smaller

00:14:09
containers like that to make sure that you have some sort of

00:14:12
fertilizer or amendment on hand that you can feed those plants

00:14:15
with throughout the season. Because in a smaller volume of

00:14:20
soil they are going to use those nitrogen, those nutrients faster

00:14:25
than they would if they had access to more soil volume.

00:14:27
So just make sure that you are feeding them on a pretty steady

00:14:31
basis. Just set yourself, you know, a

00:14:33
good three or four week schedule and just feed from there.

00:14:38
So if you're going to grow Brussels sprouts from seed, you

00:14:43
are going to want to start them about 6 to 8 weeks before your

00:14:50
last expected frost in the spring or for a fall crop about

00:14:55
four months before your first expected fall frost.

00:15:00
So yes, if you're growing them in the fall, this does mean that

00:15:03
you are going to be transplanting these out in the

00:15:05
heat of the summer. So keeping those transplants

00:15:08
cool with mulch and using good watering techniques is going to

00:15:12
be important. They will mature as the weather

00:15:15
is cooling and so they will be ready for a late fall or an

00:15:20
early winter harvest. They do like a warmer soil

00:15:25
temperature around 70 to 75 Fahrenheit or 21 to 24 Celsius

00:15:29
for germination. So if you can pop those little

00:15:32
seeds about 1/4 inch deep into your seed trays or your pots and

00:15:36
then throw them onto a heat mat and keep the soil consistently

00:15:39
moist, they should germinate for you within just a few days.

00:15:43
You can do these directly sown outside, just like all of our

00:15:46
plants. That is possible.

00:15:49
You just are going to have to pay attention to when they're

00:15:51
popping up to make sure that you're protecting them from

00:15:53
things like cut worms or even birds that will come down and

00:15:56
try to pick at the little seedlings.

00:15:59
And then you make sure that you are thinning them properly.

00:16:02
If you're going to transplant them, you want to wait to do

00:16:05
this until the seedlings are about four to six inches tall

00:16:08
and they have at least two sets of true leaves.

00:16:12
You want to space the plants about 18 to 24 inches apart, and

00:16:15
if you're doing them in rows, you want those rows to be almost

00:16:19
3 inches, 3 inches, 3 feet apart.

00:16:23
So you want to give them room to sort of expand out.

00:16:28
Again, these are growing up and they're going to be tall, these

00:16:31
stalks, but then the leaves get fairly big.

00:16:33
These are abrassica. So think about what cabbage

00:16:36
leaves look like before they start curling in on themselves

00:16:39
or what broccoli leaves look like before they start to form

00:16:41
their heads. Same thing.

00:16:42
So you want to give them enough room to be able to expand out.

00:16:46
Doesn't mean that you can't plant other things in between.

00:16:49
You know, I like to have things interplanted, but you're going

00:16:51
to plant things that are faster maturing.

00:16:54
And a good thing to do is to plant some companions with these

00:16:59
which are going to help with some of the insect pests.

00:17:02
And it's also going to fill up that space to kind of choke out

00:17:04
any weeds, give you a different harvestable crop, and and then

00:17:09
be out of there before the Brussels sprouts truly need that

00:17:13
entire space. So good companions for Brussels

00:17:15
are things like onions or garlic.

00:17:18
I have used sweet alissum and calendula and basically any

00:17:22
strong herbs that you can put in there.

00:17:26
I used to plant marigolds with all of my brassicas and I don't

00:17:32
do that anymore and I will link to the episode where I talked

00:17:36
about why marigolds are not a good idea.

00:17:41
But in short I I was doing that in order to keep the aphids and

00:17:46
the whiteflies out. But I have learned through

00:17:49
various studies that marigolds actually attract leaf hoppers

00:17:53
and spider mites and cabbage loopers and many different types

00:17:57
of flea beetles, which I don't really want in my brassicas.

00:18:02
So I stick to putting marigolds along the outer edges of the

00:18:07
garden and using herbs and alliums and beneficial little

00:18:10
flowers and stuff in between. I also avoid mustard since it is

00:18:16
in the same family and it sort of attracts the same pests.

00:18:19
But so most instances I am interplanting with green onions

00:18:22
or scallions. But I have also done fast

00:18:25
growing lettuces and arugula as well.

00:18:28
And that way those leafy greens are mature and are harvested and

00:18:33
out of the way by the time the Brussels sprouts or the cabbage

00:18:36
or whatever is is spreading its leaves.

00:18:39
So those those companion plants are always a really, really good

00:18:43
idea for a lot of reasons. So one of the things that I

00:18:46
figured out this season really made a huge difference in the

00:18:52
growth of my Brussels sprouts was the consistent moisture.

00:18:56
We have had a really wet spring and it's continued on into the

00:19:03
summertime. We also had cooler temperatures

00:19:06
for longer. So even when we had the

00:19:08
temperature spikes that often will cause my brassicas to bolt,

00:19:12
which it did some of my broccoli and my cauliflower did bolt.

00:19:15
The, the, the Brussels sprouts didn't do that.

00:19:20
And I think part of it was because they were saying so wet,

00:19:24
they were being watered so frequently from the rain.

00:19:27
I haven't had to water anything out there.

00:19:29
And of course it was a very, very deep soaking.

00:19:33
So Brussels sprouts require consistent moisture, especially

00:19:38
during dry spells. And normally in the spring by

00:19:40
the time we hit maybe mid June, Mother Nature has turned the

00:19:44
faucet off. Certainly by July it is bone dry

00:19:48
and usually very, very hot. And it just hasn't done that

00:19:52
this year. So I think that is really one of

00:19:54
the reasons why these Brussels have done so well, which means

00:19:58
to me #1 mulching is going to help retain the soil moisture.

00:20:03
It's going to suppress those weeds.

00:20:04
It's going to help to regulate that soil temperature to keep

00:20:07
them cooler. So if you do anticipate it

00:20:10
getting warmer. Early in the season, then add a

00:20:13
really good layer of mulch to help to mitigate that.

00:20:16
Make sure you have a way to water them, which is also going

00:20:18
to cool the soil and is going to help them to continue to stay

00:20:21
cool. But maybe think about adjusting

00:20:24
your planting dates a little bit.

00:20:26
This is one of the really good reasons why we keep a garden

00:20:29
journal, so we can track when it was that we planted and then

00:20:34
look at the temperatures and the moisture conditions and all the

00:20:40
other weather conditions as the season progressed.

00:20:43
And if we look at the pattern and go OK, well this year they

00:20:46
did fabulously well and this year they did horribly.

00:20:49
What was the difference between the two, if I can push that

00:20:52
planting date just a little bit earlier, maybe using row covers

00:20:57
to protect from severe frost because we don't want to kill

00:20:59
off our little seedlings out there.

00:21:01
But maybe that's going to give them a bit longer in the spring

00:21:07
to be able to get to maturity before we really start to get to

00:21:10
those hotter parts of the day. So we said start your seeds 6 to

00:21:15
8 weeks before that last expected frost date in the

00:21:18
spring. If you've been starting with the

00:21:20
six week mark, maybe it's time to move it to the eight week

00:21:24
mark. If you've been doing it at 8

00:21:26
weeks, maybe it's time to push it another week, start them a

00:21:29
little bit earlier and see if that works for you.

00:21:32
I will probably play around with this a little bit next year by

00:21:35
going back and looking historically at what my seasons

00:21:38
have looked like prior to this year and then making adjustments

00:21:42
for the temperatures. And there are online records

00:21:45
that you can see. If you have not kept these

00:21:46
records for yourself. And trust me, I am not writing

00:21:49
down the take the daytime temperatures every single day in

00:21:52
my garden journal. I'm not that crazy.

00:21:54
But there are online resources that you can use to be able to

00:21:58
look at the historical temperatures, you know, every

00:22:01
year individually or what's the average for the last five years,

00:22:04
whatever, and give yourself an idea of when those temperatures

00:22:07
really start to spike consistently in your area and

00:22:10
when the weather starts to dry out.

00:22:12
And you can make your adjustments accordingly.

00:22:16
The other thing that I think helped this year too is I was a

00:22:20
little bit better about making sure that I amended my soil one

00:22:26
more time prior to planting. A lot of the time I'm just

00:22:30
amending in the fall and allowing that to get worked into

00:22:33
the soil over the winter and then immediately planting into

00:22:36
things in the spring. But this year, with all of the

00:22:39
beds that my brassicas were going into, I added a little

00:22:43
extra at the beginning of the season to make sure that there

00:22:46
was plenty of fertility in there.

00:22:48
And those plants have all looked fabulous.

00:22:52
So that I think has also been a key.

00:22:55
So if if you didn't do that or if you haven't added, you know,

00:23:00
in the beginning of the season, you can also just feed them with

00:23:03
a balanced fertilizer about every four to six weeks during

00:23:05
the growing season. Once the sprouts start to form,

00:23:08
you can go ahead and side dress with a little bit of that

00:23:12
nitrogen that we talked about just to kind of support the

00:23:15
development. But you know from what I have

00:23:18
seen, just using a balanced amendment has worked just fine.

00:23:22
Now when they start to get tall, especially if you are growing a

00:23:27
variety that is super tall, you might need to add steaks to

00:23:32
prevent the plants from toppling over.

00:23:34
They kind of start to look almost like palm trees to me.

00:23:38
I start taking the lower leaves off to help improve the air

00:23:41
circulation. Plus that helps direct the

00:23:43
plants energy towards sprout development.

00:23:46
But you know, that means at the top they're going to have all

00:23:48
these tall leaves and they start to get a little top heavy if

00:23:51
you're growing some of the taller ones.

00:23:52
So you might want to have some steaks on hand just to prevent

00:23:56
them from flopping over on you. As we're going through the

00:24:00
season, what are the common pests and diseases that we are

00:24:03
going to have to worry about? Aphids.

00:24:06
OK, we've talked about aphids before.

00:24:07
They are those soft bodied insects that suck the SAP from

00:24:10
the plant. They cause yellowing, they cause

00:24:12
distortion. You can control these just by

00:24:16
spraying them off with a hose if you have the ability to do that.

00:24:19
You can also use an insecticidal soap or a neem oil.

00:24:24
I tend to not worry about aphids too much until I really start to

00:24:27
see a there's a really bad infestation that isn't being

00:24:31
controlled or it is starting to really 'cause damage to the

00:24:35
plants. But nine times out of 10 in my

00:24:37
garden I will see the aphids and then within about a week or so I

00:24:42
will start to see ladybugs or ladybug larvae.

00:24:45
And ladybug larvae are voracious eaters of aphids and so I don't

00:24:50
generally worried about it. The other one out of 10 times,

00:24:54
usually what I'll see is I'll see aphids and then I will see

00:24:57
ants and I will see that the ants are farming the aphids for

00:25:01
the honeydew. And that's a no, no.

00:25:02
We got to get those out of there.

00:25:03
So I just start spraying them down with with water or whatever

00:25:07
just to knock them off and get them out of there.

00:25:10
Another thing that you'll see problems with this cabbage worms

00:25:12
just like any other Brassica, it's those green caterpillars

00:25:16
that are going to chew holes in the leaves.

00:25:19
You're gonna see the cabbage moths or the cabbage butterflies

00:25:23
1st and then you will see the the cabbage worms and the

00:25:27
cabbage loopers. If you can exclude those moths

00:25:33
and butterflies to start with by using insect netting or row

00:25:36
covers, that will help, which is exactly what I did.

00:25:40
I actually started out with row covers early on to help kind of

00:25:44
keep the plants warm. Once we started to warm up a

00:25:47
little bit in the spring, I took those off and I covered them

00:25:50
with insect netting and everything stayed covered

00:25:53
completely with the insect netting basically until it

00:25:57
started to get too tall. Now with the Brussels sprouts,

00:25:59
they're starting to really push on the insect netting.

00:26:02
So I had to kind of move it or loosen it up.

00:26:05
And then I did start to see some of those moths and butterflies

00:26:07
come in. But the damage really hasn't

00:26:10
been bad at all. So I haven't had to use

00:26:13
anything. But you can use, you know,

00:26:16
biological controls like like BT or again, you can use

00:26:20
insecticidal soaps, that sort of thing.

00:26:22
The insect netting really is though a great way to help

00:26:27
protect your all of your brassicas from any one of the,

00:26:30
you know, insect pests that that you might face.

00:26:32
But usually for me, it is absolutely those cabbage

00:26:36
butterfly and the cabbage moths. One thing I've not had to deal

00:26:39
with, but it is fairly common with Brussels sprouts is cabbage

00:26:43
root maggots. So it's a white maggot larvae

00:26:47
and it tunnels in and it feeds on the roots of of the plant.

00:26:51
You won't even know what's happening.

00:26:52
You'll just start to see the plant begin to wilt early on

00:26:57
with really no reason why. I mean, if they're very well

00:26:59
watered and continue to root, you may have to check the roots

00:27:04
of the plant to see if that's what's going on because

00:27:06
eventually it's just going to kill off the plant.

00:27:08
Flea beetles. These are those small little

00:27:11
jumping beetles that create teeny tiny little holes in the

00:27:14
leaves. Again, the row covers or insect

00:27:16
netting is really good here and helps to keep those away.

00:27:21
Some people have had success using diatomaceous earth around

00:27:25
the base of their plants to help with flea beetles.

00:27:27
And then there's also Harlequin bugs.

00:27:29
These are shield shaped, so kind of similar to the shape of like

00:27:35
a a squash bug, but they suck the plant juices and that causes

00:27:39
wilting and it causes stunted growth and a lot of time you

00:27:42
just need to hand pick these again.

00:27:44
Those insect netting is going to help to prevent an initial

00:27:48
infestation and allow those plants to get to maturity much

00:27:51
more easily. In terms of diseases, you know,

00:27:55
the three things that are prevalent with most brassicas

00:27:58
are the same things that affect Brussels sprouts.

00:28:00
So downy mildew, it's that fungal disease that causes

00:28:03
yellow spots on the leaves with the fuzzy Gray underside.

00:28:07
If you can improve the air circulation, that helps, which

00:28:09
is why because it's been so rainy, I have made sure to

00:28:13
continue to pull the leaves off of the bottom of those plants to

00:28:17
help improve that air circulation.

00:28:19
You can use fungicidal sprays if you need to.

00:28:23
I have used first Saturday lime to sprinkle on it to help to dry

00:28:26
it out and adjust that that leaf pH, the surface pH to to help

00:28:31
keep the downy mildew at Bay. Black rot, this is a bacterial

00:28:35
disease that causes black lesions on the leaves and the

00:28:39
stems there as far as I know, really isn't any kind of a

00:28:43
prevention for this. It gets passed through the soil.

00:28:48
So if you've ever seen this in any of your brassicas, you need

00:28:51
to make sure that you're not planting brassicas in that same

00:28:53
spot for about 3 years. And then you can also choose

00:28:56
disease resistant varieties that that you can grow to help

00:29:00
prevent the spread of the black rot.

00:29:03
And then club root is also a soil borne disease.

00:29:06
This causes these swollen, distorted roots.

00:29:11
A lot of the time club root happens because the soil pH is

00:29:16
out of whack. So you can stick.

00:29:17
If you can get your soil to stay between that 6 and 7.5, then

00:29:21
that'll help. And then also you want to rotate

00:29:23
your crops regularly. OK, so once you get your

00:29:27
Brussels sprouts to maturity, then you have to figure out when

00:29:32
to harvest them. And this was the interesting

00:29:35
part for me because I wasn't quite sure when I was supposed

00:29:39
to start picking them. And I think it's because I had

00:29:42
seen the Brussels sprouts off the stock.

00:29:45
I've seen them in a bag or whatever in the grocery store

00:29:48
and then I had seen people cut the entire stock and sell them

00:29:53
in that manner. And I've never sort of seen the

00:29:56
in between stage. And so I sort of had to look up

00:29:59
what it was I was supposed to be doing, how I was supposed to be

00:30:01
doing it. When you were supposed to

00:30:03
harvest them. Because when we're looking at

00:30:06
cabbages, full-sized cabbages, you generally wait to harvest

00:30:11
them until they have started to fold their leaves in on

00:30:13
themselves and they are nice and firm.

00:30:17
And then basically whatever size you want them at, you can

00:30:19
harvest them whenever they're ready for Brussels sprouts.

00:30:22
They are ready to harvest when the sprouts, just like those big

00:30:25
cabbages, are firm. They are nice and green and

00:30:28
they're about one to two inches in diameter.

00:30:31
There are two different ways to do this.

00:30:33
So you can just let them grow, which is what I've done this

00:30:36
spring, and start harvesting from the bottom of the stalk

00:30:40
where the sprouts mature 1st and you just twist or cut the

00:30:44
sprouts off of the stalks. Now once you have done this, you

00:30:48
will notice as you look up the stalk that there are more teeny

00:30:52
tiny sprouts that are forming. So you can sort of have a

00:30:55
continuous harvest of these so long as the plant continues to

00:30:59
thrive happily in whatever the weather conditions are by

00:31:05
leaving the plant in the ground and just continuing to harvest

00:31:08
as the next set of sprouts are ready to harvest.

00:31:13
Now, if you want them to all mature at about the same time so

00:31:18
that you can harvest the entire stalk, then this takes some

00:31:21
forethought. Once the sprouts at the bottom

00:31:24
begin to form, you want to bend over the top of the stalk so it

00:31:29
kind of looks similar to what our onion plants look like when

00:31:33
they reach maturity and they the top sort of flop over.

00:31:36
You're wanting to sort of pinch the top down of the plant so it

00:31:41
stops the growth. This is going to stop the top

00:31:46
growth of the plant and it's going to force the energy into

00:31:49
the maturing the sprouts that have already started to form.

00:31:53
And so they're going to grow more uniformly in rates.

00:31:56
And then once they're all at that one to two inch diameter,

00:32:00
you can cut the entire stock and bring it in, or you can just

00:32:04
harvest all the heads individually.

00:32:06
So this is likely the technique that I'm going to be using for

00:32:10
the fall harvest since I'll want them to all be about the same

00:32:15
size for holiday meals versus the spring crop that I've just

00:32:20
continued to harvest from as they've come ready.

00:32:22
But I may also leave a few of them to continue to grow to see

00:32:26
just how long I can continue to harvest from them as the weather

00:32:31
gets colder and the day length gets shorter.

00:32:34
I mean, everything is an experiment in the garden, right?

00:32:38
The cool thing about Brussels sprouts is just like our other

00:32:40
brassicas, after you get that first frost, the flavor of the

00:32:45
Brussels sprouts is going to improve.

00:32:47
It's going to become sweeter. Those starches in the plants are

00:32:50
converted to sugars in the cold. So you can continue to harvest

00:32:55
off of that plant if you don't choose to pinch that top.

00:32:59
And at least until the sprouts start to become soft or the

00:33:03
plant finally succumbs to, you know, your weather.

00:33:06
If you have very cold weather and then once you have harvested

00:33:10
them, you can store your sprouts in the refrigerator in a

00:33:14
perforated plastic bag for like 3 to four weeks.

00:33:19
They store very, very well. If you need to store them longer

00:33:23
than that, then you can freeze them.

00:33:24
You want to blanch them in boiling water for about 3 to 5

00:33:27
minutes and then plunge them into ice water to cool, drain

00:33:30
them and then just freeze them either in some sort of airtight

00:33:34
container or in a freezer bag and frozen.

00:33:37
Brussels sprouts can be stored in the freezer for up to a year.

00:33:46
That's Brussels sprouts. I really do think growing these

00:33:51
is just like any other Brassica. It's all about the timing and

00:33:55
the temperature, and I think the soil moisture really does kind

00:33:59
of kick in as a little bonus thing there.

00:34:02
So if you're somewhere where cool weather is the predominant

00:34:06
season, then you likely will have easy success with Brussels

00:34:10
sprouts. If you're somewhere like me,

00:34:12
where cool weather is a total crapshoot, it will absolutely be

00:34:16
hit or miss. I got lucky this year with the

00:34:18
cooler temperatures for longer into the spring and the lovely

00:34:21
rain that we've had. But it taught me what I need to

00:34:26
look for in the fall, for growing these guys, and for

00:34:30
trying again next spring. Hopefully it helped you figure

00:34:33
it out, too. Until next time, my gardening
