Chinese Cabbage 'Michihili' problems — and how to fix them
Chinese Cabbage 'Michihili' (Brassica rapa var. pekinensis 'Michihili') is generally forgiving once you match its basics, but a few issues come up again and again. Here is what each one looks like, why it happens, and the fix.
Bolting
Spring sowings and heat or cold checks trigger early flowering before heads form. Sow from midsummer and keep growth even and unstressed.
Loose or non-hearting heads
Caused by dry soil, poor fertility, or wide spacing. Keep richly fed and moist, and space at 30-40 cm for full hearts.
Slugs and caterpillars
Cabbage caterpillars and slugs hide in the dense hearts. Net against butterflies, pick off pests, and trap slugs in damp weather.
Clubroot
Soil-borne brassica disease swelling and distorting the roots and stunting growth. Practise long rotations and lime acidic soil.
