This condition is called buttoning of cauliflower. There is no ideal size of button card  but in European countries below 9 cm sized curd is recommended as button. Causes of buttoning  1. Transplanting of aged seedling leads to buttoning.

If the growth of plant is hampered due to lack of moisture and nutrients (specially N) in the soil, then  buttoning occur. 3. Late planting of early variety will cause buttoning.  Early planting of late variety will cause buttoning. 4. Root injury also caused buttoning. Remedies o...
