🌱 Red Cabbage
About Red Cabbage
Red cabbage is a cultivated form of cabbage selected for its compact heads of anthocyanin-rich, red‑to‑purple leaves. It is typically grown as a cool-season biennial vegetable but harvested in its first year as an annual. Leaf color can shift toward red or blue depending on cooking conditions and pH.

📝 Expert Advice
Grow in fertile, firm, moisture-retentive soil with good drainage. Work in abundant compost or well-rotted manure before planting. Aim for pH ~6.5–7.5 (avoid acidic soil to reduce clubroot risk); lime acidic beds as needed. Keep soil evenly moist and avoid letting young plants check (dry out), which can trigger stress and poor head formation.
Cabbage is a heavy feeder: incorporate compost/manure pre-planting, then side-dress with nitrogen 2–3 weeks after transplanting and again as heads begin to form (avoid excessive late nitrogen, which can delay maturity and increase splitting). Use a balanced fertilizer where soil tests indicate broader deficiency; ensure adequate potassium for firm heads. Maintain near-neutral pH and adequate calcium (lime or gypsum where appropriate) to support healthy growth and reduce physiological stress.
Mulch after transplanting once soil has warmed to conserve moisture, suppress weeds, and keep roots cool in warm spells. Keep mulch a few cm away from the stem to reduce rot and slug shelter. Top up mulch during summer to maintain steady growth and reduce cracking.
No pruning. Harvest by cutting the head at the base with a knife; leave outer leaves/stump if attempting small secondary heads (more common in some cabbages). Remove yellowed outer leaves as needed.
