Cauliflower maturity groups early mid late season variety selection temperature.

Cauliflower varieties are grouped by the temperature they need to form curds, so matching the group to your planting window is critical. Early season types tolerate warmer weather and are sown for monsoon and early autumn harvest, mid season types need moderate cool weather, and late or snowball types need real winter cold and give large white curds. Planting a late type in warm weather gives loose, riced or buttoned curds and failure. Sow early types around June to July, mid season around August to September, and late around September to October in the plains, adjusting for your region. Choose named varieties recommended for each group by your state university, and confirm exact sowing windows with your local horticulture office for your district.
I learned the hard way that a snowball late variety sown too early just buttons and gives no proper curd. Now I match the variety group strictly to the month and my heads come out clean and white.
The early season crop is risky but pays the most because so few people have curd in the warm season. I keep only a small area under the very early type and the bulk under safer mid season varieties to balance the gamble.
