Frequently Asked Questions

What pest or disease is most common on Brassica oleracea var. capitata (cabbage) and how can I control it?

Cabbage often suffers from cabbageworm (imported cabbageworm/diamondback moth larvae) and can also develop black rot in humid conditions. Inspect leaves weekly, especially the undersides, and hand-pick larvae early; for heavier pressure use Bacillus thuringiensis (Bt) labeled for cabbage and apply according to label directions. To reduce black rot, avoid working plants when foliage is wet and remove and discard infected leaves promptly.

How often should I water during the main growing phase to grow firm heads of Brassica oleracea var. capitata?

During head formation, keep soil consistently moist but not waterlogged—aim for about 1 to 1.5 inches (2.5–4 cm) of water per week total, adjusting for heat and rainfall. Water deeply so moisture reaches the root zone, and avoid letting the soil dry out completely between waterings because uneven moisture can lead to loose heads and splitting. Mulch around plants to stabilize moisture levels and reduce the need for frequent shallow watering.
