Growing Mustang Clover Successfully
Like many California natives, mustang clover likely prefers conditions that mimic its natural habitat. Here are some general guidelines for success:

Planting and Care Tips
- Timing: Sow seeds in fall to align with natural rainfall patterns
- Soil prep: Ensure good drainage—this is crucial for success
- Watering: Water gently until established, then reduce frequency
