Frequently Asked Questions

What pest or disease commonly affects Brassica oleracea var. capitata (cabbage), and what should I do?

Watch for cabbage worms and aphids; both chew leaves and can leave holes or sticky residue. Use row cover after transplanting to block egg-laying, hand-pick any caterpillars you see, and spray cabbage foliage with Bacillus thuringiensis (Bt) for active caterpillars. If you see yellowing and soft, foul-smelling rot near the base or blackened inner leaves, remove affected plants promptly and avoid wetting foliage to reduce spread.

How often should I water cabbage during the main growing phase?

During head formation, keep soil evenly moist—aim for about 1 inch (2.5 cm) of water per week, adjusted for rainfall and heat. Water deeply so moisture reaches the roots, then let the top 1–2 inches (2.5–5 cm) of soil dry slightly before watering again to prevent cracking and rot. Consistent moisture is especially important from when heads start to form until harvest.

How can I tell when red cabbage (Brassica oleracea var. capitata) is ready to harvest?

Harvest when the heads are firm and feel dense when you gently press them—loose heads usually need more time. Typical maturity is about 85 days, but use firmness as your main indicator and harvest before heads split from irregular watering or heavy weather. Cut the head at the base with a sharp knife, and avoid bruising the outer leaves that protect the inner head.
