Cauliflower is cultivated much like cabbage and broccoli, both of which are close relatives. Plant indoors 1/4 in deep in loose warm soil (70 F) until the seed germinate, and then keep cooler (around 60 F). Transplant after last frost, about 5-6 weeks after germination or when there are 6 to 8 leaves. Do not wait too long to transplant or it may affect performance later on. Cauliflower needs a rich, consistently moist soil, with a ph of at least 6. Typical of this family of plants they prefer cooler conditions.
