Growing & Care Guide
1. Planting Requirements
✅ Sunlight: Thrives in full sun but can tolerate part shade.
✅ Soil: Prefers well-drained sandy, loamy, or clay soils.
✅ pH: Tolerates a wide range, from acidic to alkaline soils.
✅ Location: Ideal for coastal gardens, native landscapes, and dry areas.
2. Watering & Feeding
💧 Watering:
- Young plants: Water regularly until roots establish (first 3–6 months).
- Mature plants: Extremely drought-tolerant, only requiring occasional deep watering in dry spells.
🌱 Fertilization:
- Minimal feeding required—a light application of slow-release native fertilizer in spring can encourage growth.
- Avoid over-fertilizing, as it thrives in nutrient-poor soils.
3. Pruning & Maintenance
✂️ Pruning:
- Can be lightly pruned to shape or control spread.
- Responds well to hard pruning, if required, for rejuvenation.
🌿 Mulching:
- Apply organic mulch (e.g., bark or gravel) around the base to retain moisture and suppress weeds.
4. Pests & Diseases
🐜 Pest Resistance:
- Generally pest-free, but may occasionally attract scale insects or caterpillars.
- If needed, treat with horticultural oil or insecticidal soap.
🦠 Disease Resistance:
- Resistant to most diseases; ensure well-draining soil to prevent root rot.
5. Propagation
🌱 Propagation by Cuttings or Seeds:
- Cuttings: Semi-hardwood cuttings root well in spring or summer.
- Seeds: Can be grown from seed, but germination is slower than cuttings.
6. Landscaping & Uses
✅ Ground Cover: Forms a dense, weed-suppressing carpet.
✅ Erosion Control: Great for stabilizing sandy and sloped areas.
✅ Coastal & Drought-Tolerant Gardens: Salt-tolerant and ideal for dry conditions.
