Troubleshooting
Daikon 'Tokinashi' problems — and how to fix them
Daikon 'Tokinashi' (Raphanus sativus var. longipinnatus 'Tokinashi') 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.
Hot, sharp flavour
Heat and drought stress intensify pungency and woodiness. Keep soil consistently moist and harvest roots while young and crisp.
Forked roots
Stones, compaction, and fresh manure split the growing root. Deeply cultivate and de-stone the bed before sowing.
Splitting
Heavy rain or irrigation after dry conditions cracks roots. Maintain even moisture and mulch to smooth out fluctuations.
Flea beetles on seedlings
Beetles shot-hole young leaves in warm weather. Protect with insect mesh from sowing until plants are growing strongly.
