I won't be using row covers, just the BT to keep the bugs at bay. Maybe also DE if the situation seems to warrant it.



I have white garden cloth to reflect more light onto the cauliflower. It seemed to work on the tomatoes in that same spot last summer.



Cauliflower is my favorite vegetable. I have to try it at least once.

I think that DE is useful for beetles but I doubt that it is going to do anything to a cabbage butterfly laying eggs or a caterpillar since they do not have exoskeletons to trap the DE particles.

Bt does kill caterpillars but they have to be on the plant first to eat it so won't you have dead caterpillars on your plants? Maybe they only get on the leaves, not the head itself, I don't know because I always use row covers.

Dead caterpillars will be fine. If I'm diligent, they'll hatch tiny, eat the BT, and die tiny. I'm going to wash the cauliflower off anyway.


This place says DE is effective against caterpillars:

I asked Tormato for a couple seeds of Romanesco, so we'll see if it grows for me. I bet the advice I get here for cauliflower will go for romanesco too.

I have never heard that about DE before. That's good news.
