In this episode we're talking about which plants are worth the space, when to bring them in, and whether to keep them growing, put them to sleep, or just take cuttings. Then we'll get into my step-by-step for leaving aphids, spider mites, whiteflies, and fungus gnats outside, including why dish soap isn't the same as insecticidal soap and how long to keep new arrivals away from your houseplants. We'll finish with plant-by-plant care for peppers, rosemary, basil, and geraniums, plus a place where the experts don't agree.
Let’s dig in.
