I did not record the weather that year, which is of course a major variable. The weather varies slightly every year, but five consecutive years of failed cauliflower hints at some other cause. I mulch the garden and manage the water and fertilizer so I don't think they are the cause, and I control green caterpillars with BT. The plants look great, just no heads.

I just remembered that two years ago I saw four cauliflower seedlings at a garden shop and added them to the 12 I grew from seed. These store bought plants were in small pots and seemed a bit large for the pot size. These four all headed while all 12 of my seedlings did not.

I think I will start this year's cauliflower seedlings now and put them out at maybe 8-9 weeks to see if that helps.
