I usually can grow broccoli without spraying, but occasionally if there's some bad weather (like this week) or something else conspires to weaken the plants, the aphids or whiteflies will get out of control. I will hit them with some neem oil when that happens and all is usually well within a week or two.applestar wrote:I'm envious that you can grow broccoli year-round. Are you spraying them for pests? Bt or something stronger?
Typically I control the cabbage worms just by inspecting the plants and picking the eggs and larva off on a regular basis. If I start to notice aphids when I do this I'll squish them with my fingers, or if they're more established, some soapy spray. If I keep on it they never grow to problem levels.
I read about root maggots being a problem in the spring but I've never had an issue. :shrug:
