Growing Carrots in New Mexico's Climate
New Mexico's moderate Zone 7a climate is well-suited to carrot with minimal special accommodation. The standard transplant calendar works as written, and harvest windows line up with what seed packets recommend without adjustment.
Succession planting extends your carrot harvest significantly in New Mexico. A second planting 3 to 4 weeks after the first gives you a backup in case of pest pressure and extends the total harvest window into early fall.
Common carrot pests to watch for in New Mexico include Carrot Fly and Wireworm. The first line of defense is companion planting: Tomato and Onion planted nearby discourage several of these pests by confusing host-plant identification or repelling adults before they can lay eggs. Weekly garden walks in the early morning catch problems when they're still manageable.
