Best Time to Plant Carrots in Zone 7

1. Plant in March and April outdoors


When should I plant carrots? The general rule is to sow them outdoors two to three weeks before the final frost. As long as the ground is workable, you can put carrot seeds in the soil without worrying about freezing weather destroying them. 

Since the last frost in zone 7 is April 15 on average, zone 7a and zone 7b planting schedule can begin as early as March 25.

3. What about seeding indoors?


Carrots have sensitive roots that don’t transplant well. For this reason, we recommend planting them directly into the soil and skipping the hardening-off process.

If you insist on doing your zone 7 gardening indoors, grow carrots in pots measuring 8 to 12 inches deep, with 12 inches being the minimum depth for standard varieties. 

Sow the seeds in potting soil with a distance of one inch between them, and keep the plants in their containers until harvest. During this time, it’s best to place them near a south-facing window for proper sunlight exposure. As long as the temperatures are appropriate (40 to 75℉), your carrots should mature well.

Carrot plants should be mature and collectible before the harsh winter weather arrives. So, to ensure timely gardening zone 7 residents must sow seeds 70 to 80 days before the first frost at the latest.

Since the region’s average first frost falls on October 30, August 11 to August 21 will be the final seeding dates in zone 7a and 7b fall planting schedule.
