Frequently Asked Questions

What’s a common pest or disease problem for Daucus carota (carrot) and how do I fix it?

Carrots commonly get Alternaria leaf blight, which shows as dark, concentric spots on older leaves that can spread during humid weather. Remove and discard heavily infected tops, improve airflow with wider spacing, and avoid wetting foliage when watering—use a soaker hose or water at the soil line. If spots keep expanding, use a labeled fungicide that’s approved for edible carrots and reapply according to the label interval.

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

During the bulk of growth (roughly from after thinning until tops start to senesce), keep the bed evenly moist so the roots form straight and don’t split—aim for about 1 inch (2.5 cm) of water per week total, adjusted for rainfall and your soil. Water deeply when the top 1 inch (2.5 cm) of soil is dry, and avoid letting the soil swing between very dry and very wet, since that drives cracking and forked roots.

How can I tell when my carrots are ready to harvest?

Start checking at about 70–75 days: look for shoulder diameter near the variety’s expected size, with the top of the root pushing up slightly at the soil surface. Carrots are sweetest when harvested before they get oversized—pull one test carrot and confirm the root is firm and fully colored. If leaves are starting to yellow while roots are the right diameter, harvest promptly to prevent woody texture.
