why no heads in my cabbage?

Question

I planted purple cabbage in Dec. in my garden in San Jose, CA. The plant looks very healthy with huge leaves. It is trying to produce head but I see no head formation. Can it be due to the very warm weather?

Answer 1

Yes, warm weather can cause problems with heads forming. You can try shading the plant some or mulching the roots and extra water may help as well.
