How does it grow in the local environment:
Prostrate Rosemary performs very well in Auckland / Waikato, provided it is planted in the right position. Here’s how it holds up:
✅ Humidity Tolerance:
It can handle moderate humidity, but good airflow and soil drainage are essential to prevent mildew or root rot.
✅ Wet Winters:
Auckland’s wet winters can be a challenge if the plant is in heavy or poorly-drained soil. Raised beds, sloping ground, or sandy/loamy soils will help it thrive.
✅ Hot Summers:
Loves the warm, dry summers typical of Auckland. Once established, it's very drought-tolerant and rarely needs watering.
✅ Wind Tolerance:
Copes well with windy conditions, including coastal breezes, making it a great choice for seaside gardens.
⚠️ Tips for Success :
- Avoid planting in soggy or compacted clay soils
- Give it full sun and airflow to reduce fungal issues
- Great for banks, retaining walls, and hot, dry spots
