Troubleshooting
Curly Endive 'Frisee' problems — and how to fix them
Curly Endive 'Frisee' (Cichorium endivia var. crispum 'Frisee') 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 in heat
Hot, dry conditions or early sowing push plants to flower and turn very bitter. Sow for late-summer and autumn harvest and keep moisture even.
Failed or rotting blanch
Blanching a damp heart causes rot rather than a sweet pale centre. Blanch only dry plants by gathering and tying or covering the heart for 1-2 weeks, and check regularly.
Bitter, tough leaves
Slow, stressed growth and lack of blanching intensify bitterness. Grow fast in fertile moist soil and blanch the centre before cutting for milder flavour.
Slugs and rot in the heart
The frizzy centre traps moisture and shelters slugs. Space plants well, water in the morning at the base, and use slug control in damp autumn weather.
