Frequently Asked Questions

What pest or disease commonly affects Brassica oleracea var. capitata (Early Flat Dutch cabbage), and how can I control it?
Cabbage often suffers from clubroot (soil-borne), which causes swollen, clubbed roots and wilting even when soil looks moist. To address it, avoid planting Brassicaceae in the same spot for several years, keep soil pH closer to neutral (lime if your test is low), and remove infected plants early. If you see holes and frass on leaves, treat promptly with row cover to exclude cabbage worms and hand-remove visible eggs/larvae when possible.
How often should I water Early Flat Dutch cabbage during the main growing phase?
During head formation (roughly mid-season), keep soil evenly moist but not waterlogged—about 1 inch of water per week total, split into 2–3 deeper waterings if it’s hot or windy. Check the bed by feel: the top 1–2 inches should be consistently damp, and you shouldn’t have dry patches that lead to uneven head growth.
