Frequently Asked Questions
What pest or disease most commonly affects Brassica oleracea var. capitata (late cabbage), and what should I do?
Watch for cabbage worms (imported cabbageworm/diamondback moth larvae) and control them early with handpicking and frequent leaf checks, especially on the undersides. If damage is increasing, apply Bacillus thuringiensis (Bt) labeled for caterpillars and reapply as directed after new larvae hatch. Also manage black rot risk by removing infected leaves immediately and avoiding splashing water between plants, since Brassica can spread bacterial disease through contaminated runoff.
How often should I water Brassica oleracea var. capitata during its main growing phase (from heading formation to maturity)?
Keep soil evenly moist but not waterlogged once heads begin forming; aim for about 1 inch of water per week, adjusted for heat and rainfall. Water deeply to wet the root zone, then let the top 1 inch of soil dry slightly before watering again to prevent head splitting and root stress. During hot spells in full sun, check moisture 1–2 times per week and increase frequency while still avoiding standing water.
How can I tell when late flat Dutch cabbage (Brassica oleracea var. capitata) is ready to harvest?
Harvest when heads are firm and have filled out the flat, dense shape typical of late cabbage, usually around 95 days from transplanting/when maturity timing aligns. Use the “squeeze test”: the head should feel tight with minimal give, and outer leaves should look sturdy and mature rather than loose. If heads are firm but you see persistent loosening, leave them only briefly—late cabbage can still split if growth becomes too uneven from sudden dry/wet cycles.
