🛠️ How to Grow a Rosemary Hedge (Step-by-Step)
1. Pick the Perfect Spot
☀️ Full Sun (6–8 hours daily)
🌱 Well-draining, sandy or loamy soil
🧪 pH 6.5 to 7.5
Avoid soggy or low-lying areas—rosemary hates wet feet!
2. Prepare the Soil
- Loosen soil to 12 inches deep
- Add coarse sand or perlite for drainage
- Mix in compost (sparingly—too much is bad)
- Test pH and add lime if too acidic
3. Plant Your Rosemary
Spacing:
- 12–18 inches for dense hedges
- 2–3 feet for a looser look
Planting Steps:
- Dig holes twice the root ball width
- Place rosemary at the same soil level
- Water deeply after planting
- Add mulch (but not touching stems)
🪴 Pro Tip: Use a zigzag layout for fuller coverage!
4. Watering Schedule
- Water 1–2x per week for first 2 months
- After that: only when soil is fully dry
- In winter: water sparingly
Yellow leaves? You’re probably overwatering.
5. Pruning & Maintenance
- Lightly trim every few months
- Remove dead or woody stems
- Never cut too deep into old wood
Best Times to Prune:
- Spring & summer for shaping
- After flowering to encourage fresh growth
6. Fertilizer Tips
❌ Avoid nitrogen-heavy fertilizers
✅ Use compost tea, fish emulsion (monthly), or bone meal
Overfeeding = less aroma, weaker flavor
7. Winter Protection (For Cold Climates)
- Use frost cloths or row covers
- Mulch lightly to insulate roots
- Or grow rosemary in containers & bring indoors
🧊 Hardy varieties like ‘Arp’ or ‘Hill Hardy’ survive frost better
