Growing Conditions and Care
The beauty of creosote bush lies in its simplicity. Here’s what this desert native needs to thrive:
Sunlight: Full sun is essential—this plant has evolved to handle intense desert sunshine

Planting and Care Tips
Getting started with creosote bush is refreshingly straightforward:
- Plant in fall or early spring for best establishment
- Dig a hole only as deep as the root ball—avoid planting too deeply
- Water regularly for the first year to establish roots, then reduce to occasional deep watering
- Skip the fertilizer—this plant thrives in poor soils
- Prune only to remove dead or damaged branches
- Mulch lightly with gravel or decomposed granite rather than organic mulch
The Bottom Line
Creosote bush is a fantastic choice for gardeners in its native range who want to create sustainable, water-wise landscapes that celebrate regional character.
