Soil & Bed Preparation

Loosen soil to a depth of 10 inches, removing stones and clods that can cause forks. Blend in sifted compost or sand to keep the seedbed light and well drained.

Watering & Feeding

Mist the surface daily until germination, then switch to 1 inch of water per week applied in one deep soak. Avoid alternating drought and saturation to prevent cracking.

Skip high nitrogen amendments. Mix in kelp meal at sowing and side-dress with compost tea halfway through the season for steady growth.

Training & Maintenance

Thin seedlings twice: first to 1 inch apart, then to 2 to 3 inches depending on desired root size. Snip extras at soil level to avoid disturbing neighbors.

Harvest & Storage

Harvest when shoulders reach 3/4 inch across. Loosen the soil with a fork before pulling. Store unwashed roots in a crate of damp sand or peat in a cool space for up to six months.

Planting Instructions

  • Direct sow 2-3 weeks before last frost
  • Sow seeds thinly in rows
  • Keep soil moist until germination
  • Thin to 2 inches apart

Care Instructions

  • Keep soil evenly moist
  • Mulch to prevent green shoulders
  • Weed carefully to avoid root damage
  • No additional fertilizer needed

Seasonal Growing Calendar

Early spring

  • Direct sow as soon as soil can be worked and temperatures stay above 45 F.
  • Cover rows with burlap or shade cloth to maintain moisture until sprouting.
  • Mark rows with fast-germinating radishes to identify seed lines.

Early summer

  • Sow a second crop 10 weeks before first fall frost for storage carrots.
  • Mulch lightly to prevent soil crusting and retain moisture.
  • Hand weed regularly; carrots dislike competition.

Fall

  • Harvest storage carrots after a light frost to concentrate sugars.
  • Leave some roots in the garden under heavy straw for winter digging.
  • Remove any damaged carrots from storage bins to prevent rot spread.

Troubleshooting Guide

IssueHow to fix it
Patchy germinationKeep the seedbed evenly moist with daily misting or drip tape and resow bare spots promptly.
Forked or twisted rootsEnsure the soil is stone free, avoid fresh manure, and cut thinnings rather than pulling them.
Carrot rust fly tunnelsUse insect netting immediately after sowing and rotate plantings to a new bed each year.
