Conseils de culture
Blanch curds by tying outer leaves over the developing head when it reaches 5-7 cm to maintain white color and prevent yellowing from sunlight.
Cauliflower is sensitive to boron deficiency; apply borax at 10-15 kg/ha on deficient soils to prevent hollow stem and browning.
Avoid transplanting stress by maintaining consistent moisture and temperature; any check in growth can cause premature buttoning.
