- Choose the Right Time: Plant in autumn or early spring to allow roots to establish before high summer stress.
- Group by Water Need: Place high and low need plants together to optimize water use and minimize wastage.
Combining Beauty, Structure, and Abundance
A drought-tolerant garden doesn’t have to be sparse or colorless. By mixing perennials, shrubs, trees, wildflowers, and groundcovers, you create a tapestry of blooms, fragrance, and texture that endures through dry seasons. Focus on strong shapes, silvery or textured foliage, and extended flowering periods to maximize impact and ecological benefits.
Pollinator Appeal
- Plant a variety of bloom shapes and colors to support bees, butterflies, and hummingbirds all season.
- Leave seed heads and grasses overwinter as habitat for beneficial insects and birds.
- Avoid pesticides to encourage healthy garden biodiversity.
