Low-Water Plants.pdf

The Western Slope region of Colorado, below 7,000 feet, is classified as semi-desert shrubland with extremely low humidity, alkaline soils, and poor water infiltration. To save water and maintain a healthy garden, it's essential to choose plants native to the area.

Benefits of Native Plants

Naturally adapted to Colorado's climates, soils, and environmental conditions
Require less external inputs such as water and fertilizer
More resistant to pests and disease
Help restore habitat and maintain biodiversity
Prevent the introduction and spread of noxious weeds
Provide a special sense of place and celebrate Colorado's uniqueness and beauty

Culture and Maintenance

Soils: Native plants can thrive in unamended soils, but some may require well-drained soils. Amend clay soils with 10% compost and 15% small aggregate, and sandy or rocky soils with 3% compost.
Maintenance: Native plants require minimal maintenance, including pruning, cutting back perennials, and leaving seed heads on plants in the fall.
Watering: Water plants for at least the first season, and gradually cut back water after establishment. Some natives can be taken off irrigation completely.

Key Considerations

Choose plants native to the Western Slope region
Select plants that can thrive on little to no supplemental water
Consider soil type and amend as necessary
Minimize maintenance and watering
Leave seed heads on plants in the fall to provide food and shelter for wildlife.
