Last spring frostTypical date: April 5
First fall frostTypical date: November 5
Cool season

Plant through winter

Broccoli, lettuce, peas, carrots, radishes and leafy greens perform best from fall through early spring.

Warm season

Use spring warmth

Use the short warm season efficiently: start tender crops indoors, wait for warm soil before planting outside, and sow hardy roots and greens again for fall harvests.

Late summer

Restart the cool garden

Begin fall brassicas indoors and prepare beds for direct-sown roots and greens as temperatures moderate.

Spring planting

Planting Dates for Spring

Dates use Chaparral climate timing. New Mexico’s elevation, dry air, intense sun, and large temperature swings make soil temperature, irrigation, and timely planting especially important. Always check soil temperature and the 10-day forecast before planting.

How to Read This Calendar

1

Start indoors

Sow in trays under strong light. The window is timed so seedlings reach transplant size without becoming root-bound.

2

Transplant or plant

Harden seedlings off for about a week. Perennial crowns, sets and seed potatoes are included in this column.

3

Direct sow

Plant seed directly into prepared soil. Cool-season crops can begin before frost; heat-loving crops need warm soil.

4

Last planting

This is the practical end of the selected window—not a guarantee. Variety maturity and unusual weather can move it.

Keep soil working after harvest

Fall Cover Crop Planting Calendar

These windows are calculated from this city’s approximate first fall frost. Sow into an open bed after harvesting vegetables, then follow the selected crop’s product directions.
