11 Reasons Why Your Cauliflower May Not Form HeadsCauliflower can be a challenging vegetable to grow in the home garden. It has very specific needs, and when they aren’t met, your harvest basket may be full of green leaves, but no heads.
And while the foliage is delicious, it’s a disappointing season finale.

In this article, we’ll consider 11 reasons for cauliflower not forming heads.
1. Wrong SeedSometimes a crop is doomed from the start. This is likely to be the case when you purchase seed that is not suited to your USDA Hardiness Zone. Cauliflower thrives best with consistent temperatures ranging from 60 to 70°F.
Be sure to read seed packets carefully and choose varieties with days to maturity that match your climate’s growing season. Decide if you’ll plant a spring or fall crop, or both. Explore the latest cultivars that have improved temperature tolerance and shortened maturation periods.
2. Seedling StressCauliflower is temperamental throughout its development, especially during the germination and seedling phase.
For best results, start seeds indoors about four to six weeks before the last predicted frost date in spring. This is preferable to direct sowing, because it gives seedlings a chance to become established before facing outdoor conditions.
Transplant seedlings about two weeks prior to the last average frost date in your area, when they have grown at least two sets of true leaves. The ground should be at least 50°F.
Don’t wait too long to transplant, or your seedlings may become pot-bound, with roots that wrap around and around fail to deliver water and essential nutrients to the developing plant
