Frequently Asked Questions

What pest or disease problem commonly affects Daucus carota (carrots like ‘Nantes Coreless’), and how can I control it?

Carrot root flies (Delia spp.) are a common pest, and damaged roots often show tunneling and can attract rot. Cover seedlings with a fine insect net immediately after sowing and keep it on until harvest; remove any weeds that host adults and, if needed, use a rotating schedule where you don’t grow Apiaceae in the same bed each season. If you notice soft, rotting spots along with fly damage, lift affected roots promptly to prevent spread to neighboring plants.

How often should I water carrots (Daucus carota var. sativus) during the main growing phase?

During the bulk of growth, keep the soil evenly moist 1–2 inches down—carrots in light beds may need watering about 1–2 times per week, but only when the surface starts to dry. Avoid letting the bed swing from dry to soggy, because uneven moisture can cause cracking and forked roots; use a gentle, slow flow so the topsoil doesn’t crust and the roots can form smoothly.

How do I tell when ‘Nantes Coreless’ carrots are ready to harvest?

Harvest at about 70–80 days after sowing (near the 75-day maturity you’ll expect), when roots are typically 1–2 inches thick at the shoulder. Gently pull one test carrot; if the roots are smooth, firm, and reach the expected diameter, harvest the rest promptly to maintain sweetness. If you see roots begin to split or get woody at the shoulders, harvest immediately.
