Maintaining a beautiful landscape in Las Cruces, New Mexico requires understanding the unique rhythm of the Chihuahuan Desert seasons. Unlike temperate climates with four distinct seasons, Las Cruces experiences a hot, dry spring that transitions into a scorching summer punctuated by monsoon rains, followed by a pleasant fall and mild winter with occasional freezes. Each phase demands specific maintenance tasks to keep your yard looking its best.
At ABC Landscaping, we have developed this comprehensive seasonal maintenance calendar based on years of experience caring for landscapes throughout Las Cruces and Dona Ana County. Whether you maintain your own yard or rely on professional maintenance services, this guide ensures nothing falls through the cracks.
Winter: December through February
December
- Irrigation: Reduce watering to once every two to three weeks for established desert plants. Shut off irrigation completely during cold snaps when the ground may freeze.
- Freeze protection: Protect frost-sensitive plants like Mexican bird of paradise and bougainvillea with frost cloth when temperatures drop below 28 degrees Fahrenheit. Cover or insulate exposed irrigation backflow preventers and valves.
- Cleanup: Remove fallen leaves from deciduous trees. Clean debris from gravel beds and pathways.
- Planning: This is the perfect time to plan spring landscaping projects. Contact ABC Landscaping for a free consultation on xeriscaping, hardscaping, or other improvements.
January
- Pruning: Prune deciduous trees and shrubs while dormant. This is the ideal time for structural pruning of shade trees, fruit trees, and ornamental trees. See our tree care guide for proper techniques.
- Irrigation maintenance: Inspect your drip irrigation system for freeze damage. Replace cracked emitters, fittings, and tubing.
- Tool maintenance: Sharpen pruning shears, loppers, and saw blades. Clean and oil hand tools to prevent rust.
- Weed control: Apply pre-emergent herbicide to gravel areas before spring weeds germinate. Hand-pull any winter weeds that have appeared.
February
- Pruning: Finish dormant pruning by mid-February. Cut back ornamental grasses to 4 to 6 inches before new growth emerges. Prune red yucca flower stalks from the previous year.
- Planting: Late February is an excellent time to plant native trees, shrubs, and perennials in Las Cruces. The soil is warming and plants have time to establish roots before summer heat.
- Soil preparation: If you are planning new planting areas, now is the time to amend soil with compost and prepare beds.
- Irrigation: Begin increasing watering frequency as temperatures rise. Check all zones for proper function before the growing season begins.
Spring: March through May
March
- Planting: Prime planting season in Las Cruces. Install desert-adapted trees, shrubs, cacti, and perennials. Container-grown plants from local nurseries establish best this month.
- Fertilizing: Apply a slow-release, low-nitrogen fertilizer to established landscape plants. Desert plants generally need very little fertilizer -- over-fertilizing promotes weak, leggy growth.
- Irrigation: Transition to spring watering schedule -- once every 7 to 10 days for established xeriscaping. New plantings need more frequent water for root establishment.
- Mulching: Refresh gravel mulch in areas where it has thinned or been displaced by wind. Top-dress organic mulch to maintain 2 to 3 inch depth.
- Weed control: Stay ahead of spring weeds with regular hand-pulling or spot treatment. Weeds are much easier to control when small.
April
- Turf care: If you have Bermuda grass areas, they will be greening up now. Begin regular mowing once grass is actively growing. Apply fertilizer when grass is fully green.
- Pest watch: Inspect plants for aphids, spider mites, and scale insects, which become active in spring. Treat infestations early with insecticidal soap or horticultural oil.
- Pruning: Avoid pruning spring-blooming shrubs until after they finish flowering. Light shaping of evergreen shrubs is acceptable.
- Wind preparation: April is Las Cruces' windiest month. Stake newly planted trees. Secure loose items that could become wind-borne debris. Check that irrigation tubing is properly secured under mulch.
May
- Heat preparation: Increase irrigation frequency as temperatures begin climbing toward triple digits. Ensure all plants are adequately mulched to conserve soil moisture.
- Last chance planting: Get any remaining plants in the ground by mid-May. Planting after this point subjects new plants to extreme heat stress during establishment.
- Pruning: Light pruning of spring-blooming shrubs after flowers fade. Remove spent flower stalks from agaves and yuccas.
- Pest and disease: Watch for signs of overwatering -- root rot, yellowing leaves, fungal issues. Even in the heat, overwatering is a bigger threat to desert plants than underwatering.
Las Cruces Wind Season: Spring windstorms in Las Cruces can exceed 50 mph and cause significant landscape damage. Stake young trees, secure outdoor furniture, and clean up windblown debris promptly to prevent it from smothering plants or clogging drainage areas.
Summer: June through August
June
- Irrigation: This is typically the hottest and driest month in Las Cruces. Increase watering to every 3 to 5 days for most landscape plants. Water deeply but infrequently -- deep watering encourages deep root growth that helps plants survive extreme heat.
- Avoid pruning: Do not prune during extreme heat. Pruning stimulates new growth that is immediately stressed by high temperatures.
- Shade protection: Newly planted trees and shrubs may benefit from temporary shade cloth during the most intense afternoon sun.
- Mulch check: Verify that mulch depth is maintained at 2 to 4 inches. Gravel and organic mulch help keep soil temperatures manageable for root systems.
July
- Monsoon preparation: The monsoon season typically begins in early July. Clean drainage channels, dry creek beds, and check that all drainage systems are clear and functional.
- Irrigation adjustment: Reduce or turn off irrigation during active monsoon rain periods. A smart irrigation controller handles this automatically. Resume normal watering during dry spells between storms.
- Storm cleanup: After monsoon storms, remove debris, check for erosion damage, and redistribute gravel that may have been displaced by water flow.
- Weed surge: Monsoon moisture triggers a major weed flush. Stay on top of weeding -- desert weeds grow explosively when moisture is available.
August
- Continued monsoon management: August continues the monsoon pattern. Keep monitoring drainage and erosion. Repair any storm damage to irrigation systems and landscape features.
- Fertilizing: Apply a light feeding to warm-season turf grass if desired. Avoid fertilizing desert shrubs and trees in summer.
- Pest watch: Monsoon humidity can bring fungal issues not typically seen in Las Cruces. Watch for leaf spots, powdery mildew, and root rot on susceptible plants.
- Fall planning: Begin planning fall landscaping projects. Early fall is an excellent time for new installations, so book your contractor early. Call ABC Landscaping at (575) 323-9855 to schedule a fall consultation.
Fall: September through November
September
- Irrigation: Begin reducing watering frequency as temperatures cool. Transition from summer schedule to once every 7 to 10 days.
- Planting: Fall planting season begins. This is actually the best time to plant trees, shrubs, and perennials in Las Cruces -- mild temperatures and lingering soil warmth promote excellent root establishment before winter.
- Overseeding: If you have Bermuda grass and want a green lawn through winter, overseed with perennial ryegrass in late September.
- Cleanup: Post-monsoon cleanup of the entire landscape. Rake gravel areas, remove summer weed growth, and assess overall landscape condition.
October
- Planting: Continue fall planting. October offers ideal conditions for establishing new desert plants in Las Cruces.
- Irrigation adjustment: Reduce watering to every 10 to 14 days for established xeriscaping. New plantings still need regular water for establishment.
- Pruning: Light shaping of shrubs is appropriate. Save major pruning for winter dormancy.
- Curb appeal refresh: Fall is a great time to refresh your landscape with new seasonal color and address any areas that look tired after the brutal summer.
November
- Winterization: Drain and insulate irrigation backflow preventers and above-ground pipes before the first hard freeze. Disconnect and store garden hoses.
- Final planting: Last chance for fall planting. Get plants in the ground by mid-November to allow root establishment before winter cold.
- Leaf cleanup: Remove fallen leaves from deciduous trees, especially from gravel areas where they can decompose and promote weed growth.
- Freeze preparation: Inventory frost cloth and covers. Las Cruces typically sees its first freeze in late November. Be ready to protect frost-sensitive plants.
- Irrigation: Reduce to minimal winter watering schedule -- once every 14 to 21 days or less depending on rainfall.
Year-Round Maintenance Tasks
Some maintenance tasks are not tied to a specific season but should be performed regularly throughout the year:
- Weed management: Pull or treat weeds before they go to seed. In Las Cruces, weeds can appear year-round depending on moisture availability.
- Irrigation monitoring: Walk your property monthly and check each irrigation zone for leaks, clogged emitters, and dry spots.
- Debris removal: Keep landscape areas clean and free of litter, fallen branches, and windblown debris.
- Edge maintenance: Keep borders between gravel areas, planting beds, and pathways clean and defined.
- Plant health monitoring: Regularly inspect plants for signs of stress, pest infestations, or disease and address issues promptly.
