Quick answer

What should I do in my Las Cruces yard each season?

In winter, prune dormant trees, water deeply once a month and apply goathead pre-emergent. In spring, start up irrigation and pull weeds early. In summer, thin trees before monsoon winds and clear drainage. In fall, plant trees and shrubs and cut back watering.

August	Keep pulling goatheads before they seed; mow Bermuda regularly; second weed flush	Adjust after heavy rains
September	Last Bermuda feeding; fix monsoon damage; plan fall planting	Summer hours end September 30

Bermuda fertilizing	May to early September, while actively growing	While dormant

Common mistakes

What yard calendar mistakes do Las Cruces homeowners make?

The most common mistakes are planting in June, skipping the February goathead pre-emergent, leaving controllers on summer settings into November, not watering trees at all in winter, and topping trees in summer heat. Each one costs plants, water or a summer of weeding.

Planting in June because that’s when garden centers are full. New plants struggle through their first heat.
Skipping the February pre-emergent, then fighting goatheads all summer.
Leaving the controller on summer settings into November, wasting water and drowning desert plants.
Not watering at all in winter. Dry winter wind damages roots of trees and shrubs.
Topping trees in summer, which stresses them and exposes bark to sunscald.

A Bermuda lawn needs the most attention from May to September.

Las Cruces yard calendar FAQs

Prune most shade and fruit trees while dormant, from January to March. Thin mesquite and palo verde in late spring, before monsoon winds in July. Remove dead or broken limbs any time.

October and November. Roots grow through the mild winter before the June heat. March is the second-best window.

Usually in April as soil warms. Scalping the dormant lawn low in early spring, before green-up, helps it wake up faster, according to NMSU Extension.
