Growing California Threeawn Successfully
The good news is that California threeawn is remarkably easy to grow, especially if you’re gardening in USDA hardiness zones 8-10. Here’s what this adaptable grass needs to thrive:
Ideal Growing Conditions

Planting and Care Tips
Getting your California threeawn off to a good start is straightforward:
