Frequently Asked Questions

What pests or diseases commonly attack Brassica oleracea var. capitata (Copenhagen Market cabbage), and what should I do?

Watch for cabbage worms (imported cabbageworm/diamondback moth) and aphids on the leaves; start control early by hand-picking larvae and spraying cabbage with an organic Bt (Bacillus thuringiensis) labeled for caterpillars. Also monitor for clubroot—stunted plants with swollen roots—by avoiding planting in the same spot and improving drainage; if clubroot appears, remove affected plants and don’t replant cabbage-family crops there for several years.

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

During head formation (roughly mid-season until harvest), keep the soil consistently evenly moist, not waterlogged. Aim for about 1–1.5 inches of water per week from rainfall plus irrigation, increasing during hot spells, and use mulch to prevent the soil from drying out between waterings (dry-wet swings can lead to head splitting).

How can I tell when Copenhagen Market cabbage is ready to harvest?

Harvest when the heads feel firm when gently squeezed and the outer leaves look full and tightly wrapped, typically around 75 days from transplanting/appropriate schedule. Heads should be at their mature size but still crisp—if they start to loosen or leaves separate, harvest immediately to avoid cracking from late-season stress.

Copenhagen Market brings a crisp, sweet cabbage heart with a cool, fresh crunch and a tender, finely textured bite. Forming tight, round heads with a clean, pale interior and a deep green outer wrap, it’s a dependable 75-day favorite for gardeners who want uniform results and beautiful harvests. Ideal for fresh use, slaws, and tangy fermented preparations, this variety shines wherever you want cabbage flavor with a bright, lively character.

Sowing Tips

Transplant Conditions

Wait until soil reaches 40°F and nights stay above 32°F before moving outdoors. Harden off for 7 days first.

Expert Note

For dense sauerkraut heads, keep plants evenly watered and aim to transplant while nights are still cool for tight head set.
