Troubleshooting
Carrot 'Parmex' problems — and how to fix them
Carrot 'Parmex' (Daucus carota subsp. sativus 'Parmex') 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.
Overcrowding
Round carrots size up only with room; thin to about 4 cm apart or roots stay tiny and misshapen.
Drying out in pots
Containers swing between wet and dry quickly, splitting the globes; mulch the surface and water little and often in heat.
Carrot fly
Still a risk even in pots; raising containers above 60 cm or using mesh covers deters the low-flying pest.
Slow or patchy germination
Keep the seedbed or compost surface consistently moist; carrot seed germinates poorly if the surface crusts and dries.
