Romanesco

Question

My Romanesco plants are about 2 feet tall and there’s no sign of heading. Shouldn’t there be heads forming by now?

Answer 1

It is still very early, and it appears that you have a shade cloth over them. They prefer full sun. They are quite a bit more heat tolerant than their cousins, broccoli and cauliflower. If you don't see flowers forming in another month or two, then I would think about adding some phosphorus and potassium to the soil.

Generally, in order for them to flower properly, you will want them quite a bit bigger. Patience will be key here.
