Paris Market Carrot problems — and how to fix them
Paris Market Carrot (Daucus carota 'Paris Market') 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.
Carrot root fly (Psila rosae)
Larvae tunnel into roots, causing rusty scarring and rot. Use fine insect-mesh barriers from sowing; avoid crushing foliage (the smell attracts flies). Companion-plant with alliums or grow under fleece.
Forked or misshapen roots
Caused by stony or compacted soil, fresh manure, or transplanting (carrots dislike root disturbance). Always sow direct, deeply loosen soil, and remove stones before sowing.
Poor germination
Seeds are slow to germinate (14–21 days). Soil must be at least 7°C; cold or waterlogged soil causes seed rot. Keep surface moist with a fine mist; thin to 5 cm once seedlings reach 5 cm tall.
