Growing Tips

Harvest the central head while buds are still tight and before yellow flowers appear; side shoots will continue producing for several weeks.

Apply 2-3 split nitrogen applications rather than one heavy dose to promote steady growth and prevent hollow stems.

Use row covers to protect transplants from cabbage white butterflies and flea beetles during early establishment.
