Poor curd formation in cauliflower is almost always a mismatch between the variety and the temperature, plus stress. Buttoning, where tiny curds form on small plants, happens when an early or wrong variety meets cold too soon or seedlings are starved and check their growth. Riceyness and loose, fuzzy curds happen when warm weather hits at curd formation, often from sowing a late winter variety too early. Fix it by choosing the variety group that matches your sowing month, raising strong healthy seedlings without nutrient or moisture stress, transplanting on time and keeping steady moisture and balanced nutrition through curding. Protect curds from sun by tying outer leaves over them for whiteness. Confirm the correct variety group for each sowing window with your local horticulture office or KVK in Hooghly.
My gobhi was buttoning until our KVK told me I was using a late variety too early in the season. Once I matched the variety to the month and stopped letting the seedlings get stressed, the curds came out full and white.
Do not let the seedlings sit too long and get root bound or starved in the nursery. A checked, stunted seedling tends to button early once it goes to the field. I transplant at the right age into well prepared soil and the plants grow on without that early shock.
Once the curd starts forming I tie the outer leaves loosely over it. In our Hooghly winter sun the exposed curds turned yellowish, but blanching them this way keeps them white and the trader pays more for the clean colour.
Keep the moisture and feeding steady right through curding. When I let the crop go dry or skipped a top dressing at the wrong time, the curds came loose and ricey even with the correct variety. Steady care during head formation is as important as the variety choice.
