Troubleshooting
'French Breakfast' Radish problems — and how to fix them
'French Breakfast' Radish (Raphanus sativus 'French Breakfast') 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.
Pithy, hot roots
Left too long in the ground or grown in heat, roots become spongy, hollow and sharply pungent. Harvest promptly at 3-4 weeks and grow in cool weather.
Bolting
Summer heat and long days trigger fast bolting before roots size up. Sow in spring and autumn and avoid the hottest months.
Flea beetle holes
Flea beetles pepper the leaves with pinholes, weakening fast-growing seedlings. Protect with row cover from sowing.
All leaf, little root
Overcrowding, shade, or excess nitrogen produce big tops and tiny roots. Thin early to about 2.5 cm apart and keep fertility modest.
