Benefits of Xeriscaping in Colorado
Implementing xeriscaping in Colorado landscapes offers significant advantages that extend beyond simple water savings.
These landscaping principles work particularly well in Colorado's semi-arid climate and variable weather conditions.
Water Conservation
Xeriscaping can reduce water usage by as much as 70 percent compared to traditional landscaping.
This substantial reduction is especially important in Colorado, where water resources are increasingly limited and drought periods are common.
During summer months, traditional lawns typically require thousands of gallons of water to maintain their appearance.
Xeriscaped properties dramatically decrease this demand on municipal water systems and private wells.
The water savings translate directly to lower utility bills for homeowners.
Many Colorado water districts offer rebates and incentives for residents who convert traditional lawns to water-wise landscapes, providing additional financial benefits.
Colorado's periodic water restrictions become less problematic for xeriscape gardens.
These landscapes thrive with minimal supplemental irrigation once established, usually requiring water only during extreme drought conditions.
Low Maintenance
Xeriscaped yards require significantly less upkeep than conventional landscapes.
Native and drought-tolerant plants naturally resist local pests and diseases, reducing the need for chemical treatments.
Properly designed xeriscapes minimize mowing, trimming, and other time-consuming maintenance tasks.
This frees up weekends previously dedicated to yard work, especially beneficial during Colorado's short summer season.
Mulched areas in xeriscapes suppress weeds naturally and reduce soil erosion from Colorado's intense thunderstorms.
Organic mulches gradually break down, enriching the soil and reducing the need for fertilizers.
Xeriscaped properties typically require less equipment like lawnmowers and trimmers.
This decreases both maintenance costs and the environmental impact associated with gas-powered landscape tools.
Year-Round Aesthetics
Contrary to misconceptions, xeriscaping creates stunning, vibrant landscapes that showcase Colorado's natural beauty through all seasons.
Strategic plant selection ensures visual interest throughout the year.
Native wildflowers provide spectacular color during spring and summer, while ornamental grasses add movement and texture that persists through fall and winter.
Many xeriscape plants feature distinctive seed heads, bark patterns, or evergreen foliage for winter appeal.
Xeriscaping supports local wildlife by providing habitat for pollinators and birds.
This creates a more dynamic and engaging landscape experience than traditional lawns.
The diverse textures, colors, and forms available in drought-tolerant plants allow for creative expression in landscape design.
Each xeriscaped yard becomes a unique reflection of Colorado's natural environment rather than a cookie-cutter lawn.
Selecting the Right Plants
The success of a Colorado xeriscape depends on choosing plants that naturally thrive in arid conditions while considering your specific location's characteristics.
Proper plant selection saves water, reduces maintenance, and creates a resilient landscape that can withstand Colorado's challenging climate.
Native Plants
Colorado native plants have evolved to thrive in the region's unique climate conditions, making them ideal xeriscape choices.
Apache Plume (Fallugia paradoxa) features feathery, pinkish seed plumes that add movement and texture to the landscape while requiring minimal water.
Panchito Manzanita (Arctostaphylos coloradoensis) offers evergreen foliage and distinctive reddish bark that provides year-round interest. This low-growing shrub works wonderfully as ground cover in challenging spots.
Rocky Mountain penstemon delivers vibrant purple-blue flowers that attract pollinators while tolerating dry conditions. Blue grama grass forms attractive clumps with distinctive seed heads, providing movement and winter interest.
When selecting native plants, gardeners should consider mature size and growth habits to ensure proper spacing.
Native plants typically require minimal supplemental water once established, usually within 1-2 growing seasons.
Drought-Tolerant Non-Natives
While native plants excel in Colorado xeriscapes, many non-native species also perform admirably while conserving water.
Lavender (Lavandula) brings Mediterranean charm with its aromatic purple blooms and silver-gray foliage, thriving in Colorado's sunny, well-drained sites.
Russian sage creates dramatic height with its silver stems and purple flower spikes, blooming throughout summer with minimal care. Yarrow offers flat-topped flower clusters in various colors from yellow to red, spreading moderately in the landscape.
Popular Drought-Tolerant Non-Natives:
Catmint (Nepeta)
Ice Plant (Delosperma)
Sedum varieties
Ornamental grasses like Maiden Grass
Rabbit Brush
These adaptable plants should be grouped according to water needs to optimize irrigation efficiency.
Many drought-tolerant non-natives perform best when receiving deep, infrequent watering rather than frequent shallow irrigation.
Soil and Sunlight Considerations
Careful evaluation of soil, drainage, and exposure to environmental factors is essential when selecting xeriscape plants.
Colorado soils often contain heavy clay or excessive sand, both presenting challenges that may require amendments before planting.
Most xeriscape plants prefer well-draining soil to prevent root rot. Adding compost improves both clay and sandy soils, enhancing drainage while maintaining adequate moisture retention.
Raised beds or berms can improve drainage in areas with heavy clay.
Sunlight patterns significantly impact plant performance.
Mapping the yard and noting exposure levels helps identify appropriate planting zones.
Full-sun areas (6+ hours daily) accommodate most xeriscape plants, while partially shaded areas require specialized selections.
Wind exposure also affects plant success, with some varieties tolerating windy conditions better than others.
Grouping plants with similar sunlight and wind tolerance creates microclimates that optimize growing conditions while simplifying maintenance routines.
Designing Your Xeriscape Garden
Creating a successful xeriscape requires thoughtful design that balances water conservation with visual appeal.
A well-planned xeriscape garden saves water while providing year-round interest through strategic plant selection and placement.
Planning and Layout
Begin by analyzing your yard's conditions including sun exposure, soil type, and water drainage patterns.
Proper planning is the first step in creating a water-efficient landscape.
Create distinct hydrozones, grouping plants with similar water needs together to prevent overwatering.
Consider functional needs when designing your space. Designate areas for recreation, entertaining, and visual enjoyment. Incorporate pathways that direct foot traffic and create visual flow throughout the garden.
Scale your design appropriately for your yard size. Small yards benefit from simple plans with fewer plant varieties, while larger spaces can accommodate more diverse plantings.
Use curved, flowing lines rather than rigid geometry to create a more natural appearance. This approach mimics Colorado's native landscapes and creates visual interest even during dormant seasons.
Combining Colors and Textures
Select plants with varied bloom times to ensure color throughout the growing season.
Early spring bulbs, summer-flowering perennials, and fall-blooming asters create sequential interest.
Incorporate plants with contrasting foliage textures. Pair fine-textured plants like ornamental grasses with broad-leaved perennials for visual diversity.
Native grasses provide movement and sound, enhancing the sensory experience.
Consider Colorado's intense sunlight when selecting colors. Silvery foliage plants like sage and lavender reflect light and remain attractive even when not flowering.
Add structure with water-wise garden plans that incorporate drought-resistant shrubs and small trees.
These anchor the landscape and provide year-round visual interest through form, bark texture, and seasonal changes.
Mulching and Ground Covers
Apply 2-4 inches of organic mulch around plants to suppress weeds, reduce evaporation, and moderate soil temperature.
Wood chips, straw, and compost break down over time, improving soil structure and fertility.
For a more permanent solution, consider inorganic mulches like decorative rock or gravel. These materials complement xeriscape aesthetics while providing excellent drainage and weed suppression. Choose colors that complement your home and garden design.
Incorporate living ground covers as an alternative to mulch in appropriate areas.
Low-growing sedums, creeping thyme, and native ground covers reduce soil erosion and provide habitat for beneficial insects.
Denver Water's xeriscape plans recommend leaving space between plants when first installing your garden. This allows room for growth and reduces competition for water and nutrients as plants mature.
Xeriscape Care and Maintenance
Successful xeriscapes require specific maintenance strategies to thrive in Colorado's challenging climate while conserving water.
Proper care techniques differ significantly from traditional landscape maintenance and change with the seasons.
Irrigation Strategies
Efficient watering is crucial for xeriscape success in Colorado.
Water the root zones of plants when daytime temperatures reach 40 degrees if there's no precipitation.
New xeriscape plants require regular watering until established, typically for 1-2 years.
After establishment, gradually reduce supplemental watering to encourage deep root growth.
Group plants with similar water requirements together to prevent overwatering some while underwatering others.
Drip irrigation systems deliver water directly to plant roots, minimizing evaporation and runoff.
Set timers to water during early morning hours when evaporation rates are lowest.
Adjust irrigation schedules seasonally—increase frequency during hot, dry periods and reduce or eliminate during cooler, wetter months.
Monitor soil moisture regularly using a soil probe or moisture meter rather than following a rigid schedule.
This practice ensures plants receive water only when needed.
Pruning and Weeding
Proper pruning maintains plant health and appearance in xeriscapes.
Prune deciduous trees and late-blooming shrubs during dormant winter months to encourage healthy spring growth.
Remove dead or damaged branches promptly to prevent disease spread.
For flowering perennials, deadhead spent blooms to encourage additional flowering and prevent unwanted self-seeding.
Leave ornamental grasses intact through winter for visual interest, cutting them back in early spring before new growth emerges.
Regular weeding prevents unwanted plants from competing for limited water resources.
Apply 2-4 inches of mulch to suppress weeds and retain soil moisture.
Pull weeds when young before they establish deep roots or set seed.
Consider using landscape fabric beneath mulch in highly weed-prone areas, but avoid plastic sheeting which prevents proper soil respiration.
Hand-pulling is preferable to chemical herbicides which may harm beneficial insects and soil microorganisms.
Seasonal Adjustments
Colorado xeriscapes require specific maintenance as seasons change.
In spring, remove winter mulch from around plant crowns to prevent rot and allow new growth. Apply fresh mulch as temperatures rise to prepare for summer heat.
Summer care focuses on monitoring water needs during hot periods.
Check for signs of stress such as wilting or leaf curl. Morning inspections provide the most accurate assessment of plant health.
Fall maintenance includes reducing irrigation as temperatures cool.
Cut back perennials after first frost unless they provide winter interest or bird habitat. Leave fallen leaves in planting beds as natural mulch where appropriate.
Winter care is minimal but important.
Waterduring dry spells when temperatures exceed 40°F, focusing on recently planted specimens and evergreens. Avoid walking on frozen plant beds to prevent soil compaction and damage to dormant plants.
