Carrot in a Zone 10 season

Zone 10 gives about 318 frost-free days. Carrot needs roughly 70 days from sowing. That leaves about 248 days of slack, so there is room for a late start or a second planting.

Sowing every 21 days, Zone 10 has room for about 12 plantings.

How to grow carrots

Sow directly in loose, stone-free soil in the cooler part of the year, once the soil is no longer cold. Keep the seedbed moist until germination, which can take 2 to 3 weeks. Resow every few weeks while the weather stays mild.
