Turnip 'Tokyo Cross' problems — and how to fix them
Turnip 'Tokyo Cross' (Brassica rapa var. rapa 'Tokyo Cross') 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.
Flea beetle
Peppers young leaves with small holes and slows the fast early growth this F1 depends on; cover seedlings with fine mesh and keep them well watered.
Splitting
Because growth is so rapid, leaving roots in the ground too long or heavy rain after dry spells splits them; harvest promptly at golf-ball size.
Clubroot
Brassica soil disease distorting roots; rotate brassicas, improve drainage and lime to raise pH.
Pithy roots if over-mature
Tokyo Cross is bred for early, tender harvest; left too long roots lose their sweetness, so pick young and successionally re-sow.
