Fall Planting Guide for Las Cruces

In most of the country, spring is planting season. In Las Cruces, fall is. Plants set out in late September and October grow roots through a mild winter and are ready for June heat, while spring plantings get only a few weeks before summer hits. Here’s what to plant this fall, what to wait on, and how to water it.

Quick answer

When is the best time to plant in Las Cruces?

Fall is the best time to plant most trees, shrubs, native grasses and perennials in Las Cruces. Plant from late September to early November, about six weeks before the average first freeze around November 11, so roots settle in while the soil is still warm.

Frost-tender plants are the exception. Cacti and succulents from warmer deserts, and other cold-sensitive plants, do better planted in spring after the last freeze in mid-March.

Why fall

Why is fall better than spring for planting here?

Fall plantings get warm soil for root growth, cool air that doesn’t stress leaves, and six to eight months before summer heat. Spring plantings in Las Cruces get only a few weeks before 100-degree days, with small roots and high water demand.

Does warm soil really matter?

Yes. Roots keep growing in warm fall soil even as tops slow down, so plants anchor in before winter.

Does fall planting save water?

It does. Cooler weather means less evaporation, and established roots need far less water the next summer.

Are fall plants cheaper?

Often. Many nurseries clear summer stock in fall, and you avoid replacing spring plantings that cooked in June.

How to plant

How do I plant trees and shrubs in the fall?

Dig a hole two to three times wider than the root ball and no deeper, check that it drains, set the plant at the same depth it grew in the pot, backfill with native soil, water deeply, and put drip emitters at the edge of the root ball.

1

Call 811 first

Have utility lines marked before digging.

2

Dig wide, not deep

Two to three times the root ball width, same depth.

3

Test drainage

Fill the hole with water. If it sits for hours, there’s caliche to break through.

4

Plant at grade

Top of the root ball level with or slightly above the soil.

5

Backfill and soak

Use native soil and water deeply to settle it.

6

Set the drip

Emitters at the root ball edge, moved outward as it grows.

Watering

How often should I water new plants in fall and winter?

Water new fall plantings deeply every few days for the first two weeks, then about weekly through October and November, and every two to three weeks in winter. Dry winter wind pulls moisture from young plants, so don’t stop watering entirely.

  • Fix drainage problems the monsoon revealed
