Common Name: Munstead Lavender
Family: Lamiaceae
Type: Perennial Herb

1. Site Selection

Sunlight

• Full sun: At least 6–8 hours daily for best flowering.

Soil

• Needs well‑drained soil
• Prefers sandy or loamy textures
• Avoid heavy clay unless improved for drainage

2. Soil Preparation

pH Range

• Slightly alkaline to neutral (6.5–7.5)

Amendments

• Add grit or sharp sand if needed for drainage
• Mix in compost or well‑rotted manure lightly (lavender dislikes overly rich soils)

3. Planting

Spacing

• Plant 12–18 inches apart for airflow and shape

Depth

• Plant at the same depth as it was in its nursery container

4. Watering

Initial Care

• Water well after planting to settle roots

Ongoing Watering

• Water deeply but infrequently
• Allow soil to dry between waterings
• Once established, lavender thrives in drier conditions

5. Fertilising

When

• Early spring

How

• Use a low‑nitrogen fertiliser
• Avoid excess feeding—too much nitrogen = floppy, leafy growth and fewer flowers

6. Pruning

Best Time

• Late winter or early spring before new growth

How to Prune

• Cut back one‑third of the plant
• Avoid cutting into old woody stems
• Aim to maintain a compact, dome shape which prevents splitting

7. Pests & Disease Management

Common Issues

• Root rot from poor drainage
• Occasional fungal problems in humid weather

Pests

• Generally pest‑resistant
• May see aphids or spider mites—treat with water spray or organic soap if needed

8. Harvesting

When

• Harvest flowers when fully open for maximum fragrance
• Morning harvest is best when oils are at their peak

How

• Cut stems cleanly above a leaf node

9. Uses

Culinary

• Lavender sugar, biscuits, syrups, teas

Aromatherapy

• Ideal for oils, sachets, pillow blends, potpourri

Landscaping

• Perfect for:
  • Path edging
  • Mediterranean borders
  • Gravel gardens
  • Wildlife‑friendly gardens (pollinator magnet!)

10. Hardiness

• Hardy in USDA zones 5–9
• In very wet winters, ensure excellent drainage or plant on a mound

Additional Tips

Companion Plants

• Rosemary
• Sage
• Thyme
• Other drought‑tolerant herbs

Mulching

• Use gravel or stone mulch to reflect heat and aid drainage
