How to Grow a Rosemary Hedge (Step-by-Step Guide)
1. Choose the Right Location
Rosemary thrives in warm, sunny locations with well-draining soil.
- Sunlight: At least 6-8 hours of direct sun daily.
- Soil Type: Sandy, loamy, or well-draining soil (avoid clay or wet areas).
- pH Level: Slightly alkaline (6.5 – 7.5).
- Protection: Rosemary can tolerate some wind but prefers a sheltered spot.
Avoid planting rosemary in low-lying areas where water collects—this can lead to root rot.
2. Prepare the Soil
Healthy soil is essential for a thriving rosemary hedge.
- Loosen the soil to at least 12 inches deep to promote root growth.
- Mix in coarse sand or perlite to improve drainage.
- Add compost or aged manure (but go easy—rosemary prefers nutrient-poor soil).
- Test the soil pH—add lime if your soil is too acidic.
If your soil is heavy clay, plant rosemary in raised beds or on a mound to improve drainage.
3. Planting the Rosemary Hedge
Now it’s time to plant your rosemary hedge!
Spacing:
- 12-18 inches apart for a dense hedge.
- 2-3 feet apart for a looser, natural look.
Planting Steps:
- Dig holes twice as wide as the root ball.
- Place the rosemary at the same depth as in the pot.
- Fill in with soil and firm it down gently.
- Water deeply right after planting.
- Add a thin layer of mulch to retain moisture (but keep it away from the stems!).
Pro Tip: Stagger plants in a zigzag pattern for a thicker hedge.
4. Watering the Rosemary Hedge
Rosemary hates soggy soil, so water wisely!
- First 2 Months: Water once or twice a week until the roots establish.
- After Establishment: Water only when the soil is completely dry.
- Winter: Reduce watering even more—rosemary is semi-dormant in cold months.
Avoid overwatering! If rosemary’s leaves turn yellow, you’re watering too much.
5. Pruning & Maintaining the Hedge
Pruning keeps your rosemary hedge tidy, encourages bushy growth, and extends its lifespan.
How to Prune:
- Trim back 1-2 inches every few months to maintain shape.
- Remove dead, damaged, or woody stems.
- Avoid cutting into old, woody growth—rosemary struggles to regrow from hardwood.
When to Prune:
- Spring & Summer: Light trimming for shaping.
- Late Summer/Early Fall: Hard prune before winter.
- After Flowering: Deadhead spent flowers to promote new growth.
Harvesting rosemary regularly encourages new, soft growth—so don’t be afraid to use it!
6. Fertilizing & Feeding Rosemary
Rosemary doesn’t need heavy feeding—too much fertilizer can weaken its fragrance and hardiness.
Best Fertilizers:
- Diluted fish emulsion (once a month in spring/summer).
- Compost tea for a gentle nutrient boost.
- Bone meal for strong root development.
Avoid high-nitrogen fertilizers—they promote leafy growth at the expense of essential oils.
7. Protecting Rosemary from Winter Cold
Rosemary is sensitive to frost, especially in zones 6 and colder.
In Cold Climates:
- Use row covers or frost blankets during freezing nights.
- Mulch lightly to insulate the roots (but keep mulch away from the stems).
- Grow rosemary in containers to bring indoors in winter.
Hardy varieties like ‘Arp’ and ‘Hill Hardy’ can survive light frost.
