How to Care for Lavender: A Complete, Easy Guide
Lavender is a hardy, fragrant, and low-maintenance plant when grown in the right conditions. Native to the Mediterranean, it thrives on sun, dry roots, and free-draining soil. Most lavender problems are caused by overwatering, poor drainage, or lack of sunlight rather than neglect. Once established, lavender needs very little attention and will reward you with years of flowers, scent, and pollinator activity.
This guide explains how to care for lavender properly, whether it’s grown in the garden or in a pot.
Choose the Right Position
Lavender must be grown in full sun to stay healthy.
- Needs 6–8 hours of direct sunlight per day
- Sun encourages compact growth and strong flowering
- Shady positions lead to leggy plants and few flowers
South- or west-facing spots are ideal.
Soil Requirements (Most Important Step)
Lavender hates wet soil. Drainage is the key to success.
Ideal Soil
- Free-draining
- Light, gritty, or sandy
- Neutral to alkaline pH
Avoid
- Heavy clay soil
- Waterlogged ground
- Rich, compost-heavy soil
If your soil is clay:
- Add grit or sharp sand
- Plant on a mound or slope
- Use raised beds or pots
Lavender prefers poor soil to rich soil.
Watering Lavender Correctly
Lavender is drought tolerant once established.
In the Ground
- Water lightly after planting
- After establishment, water only during prolonged dry spells
In Pots
- Water only when compost is completely dry
- Always empty saucers after watering
- Never water little and often
Overwatering is the number one reason lavender dies.
Growing Lavender in Pots
Lavender grows very well in containers when drainage is good.
- Use pots with drainage holes
- Terracotta pots are best
- Use gritty compost mixed with sand or grit
- One plant per pot (30–40 cm wide)
Pots are ideal for patios, balconies, and gardens with poor soil.
Pruning Lavender (Essential for Longevity)
Pruning keeps lavender compact and prevents it becoming woody.
When to Prune
- Light prune after flowering
- Shape again in spring
How to Prune
- Cut back around one-third of the plant
- Always leave green growth
- Never cut into hard, woody stems
Regular pruning encourages more flowers and extends plant life.
Feeding Lavender
Lavender needs very little feeding.
- Avoid high-nitrogen fertilisers
- Do not use manure or rich compost
- Feeding is usually unnecessary
Too much fertiliser causes leafy growth with fewer flowers.
Spacing and Airflow
Lavender dislikes crowded, damp conditions.
- Space plants 30–45 cm apart (depending on variety)
- Ensure good airflow around plants
- Avoid planting too close to walls or fences
Good airflow reduces disease and keeps foliage dry.
Flowering Care
Lavender usually flowers from late spring through summer.

Deadheading spent flowers can encourage repeat blooms.
Winter Care for Lavender
Winter damage is usually caused by wet soil, not cold.
Hardy Lavender
- Can stay outdoors
- Needs excellent drainage
- Avoid winter watering
Less Hardy Types
- Best grown in pots
- Move to a bright, sheltered place in winter
- Protect from frost and excessive rain
Raising pots off the ground helps excess water drain away.
Common Lavender Problems and Fixes
Yellow Leaves
Usually caused by overwatering or poor drainage.
Woody, Leggy Growth
Caused by lack of pruning or too much shade.
Few or No Flowers
Often due to low sunlight, excess feeding, or incorrect pruning.
Wilting Despite Watering
Usually root rot — improve drainage immediately.
Lavender rarely suffers from pests; most issues are environmental.
Can Lavender Be Grown Indoors?
Lavender prefers outdoor conditions but can be grown indoors short-term.
- Place in the brightest window possible
- Ensure excellent drainage
- Water sparingly
- Provide airflow
Long-term indoor growth is difficult due to light levels.
Benefits of Growing Lavender
With proper care, lavender offers:
- Fragrant flowers
- Attractive silvery foliage
- Pollinator-friendly blooms
- Drought tolerance
- Low maintenance
- Long lifespan
Lavender works beautifully in borders, pots, paths, and herb gardens.
