How to Look After a Lavender Plant: Complete Care Guide

Lavender is a hardy, fragrant plant that thrives when its natural Mediterranean preferences are met. It is low maintenance once established, but it does have specific needs — particularly around sunlight, drainage, watering, and pruning. Most lavender problems come from overwatering or poor soil, not neglect.

This guide explains how to look after a lavender plant properly, whether it’s growing in the ground or in a pot.

---

Give Lavender Full Sun

Lavender must be grown in full sun to stay healthy and flower well.

• Needs at least 6–8 hours of direct sunlight per day
• Sun keeps plants compact and encourages strong flowering
• Too much shade causes weak, leggy growth and fewer flowers

If lavender isn’t blooming, lack of sunlight is often the main reason.

Use Free-Draining Soil

Drainage is the single most important factor in lavender care.

Best Soil for Lavender

• Light, gritty, well-drained soil
• Sandy or chalky soil is ideal
• Neutral to alkaline pH

Avoid

• Heavy clay soil
• Waterlogged ground
• Rich, compost-heavy soil

If your soil is heavy, improve it with grit or grow lavender in raised beds or pots.

Water Lavender Sparingly

Lavender is drought tolerant and hates sitting in wet soil.

Lavender in the Ground

• Water after planting
• Once established, water only during prolonged dry spells

Lavender in Pots

• Water only when compost is completely dry
• Always empty saucers after watering
• Never water little and often

Overwatering is the most common reason lavender plants die.

Choose the Right Pot (If Growing in Containers)

Lavender grows very well in pots when drainage is good.

• Always use pots with drainage holes
• Terracotta pots are best as they dry out faster
• Use gritty compost mixed with sand or grit

Pots are ideal for patios, balconies, and gardens with clay soil.

Prune Lavender Every Year

Pruning is essential for keeping lavender healthy and long-lived.

When to Prune

• Light prune after flowering
• Shape again in spring

How to Prune

• Cut back around one-third of the plant
• Always leave some green growth
• Never cut into old, woody stems

Regular pruning prevents lavender becoming woody and encourages more flowers.

---

Feed Very Little (or Not at All)

Lavender prefers poor soil.

• Avoid high-nitrogen fertilisers
• Do not use manure or rich compost
• Feeding is usually unnecessary

Too much feeding causes leafy growth and fewer flowers.

---

Ensure Good Airflow

Lavender dislikes damp, still conditions.

• Space plants well apart
• Avoid overcrowding
• Grow in open, airy positions

Good airflow helps prevent fungal problems and root rot.

---

Lavender Flowering Care

Lavender usually flowers from late spring to summer.

To encourage strong flowering:

• Grow in full sun
• Prune after flowering
• Avoid overwatering
• Do not overfeed

Removing spent flowers can encourage repeat blooms.

---

Winter Care for Lavender

Winter problems are usually caused by wet soil, not cold.

English Lavender

• Hardy outdoors
• Needs excellent drainage
• Avoid winter watering

French and Spanish Lavender

• Less frost-hardy
• Best grown in pots
• Move to a bright, sheltered spot in winter

Raising pots slightly 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

Indoor lavender often struggles long-term due to low light.

• Fragrant flowers
• Attractive silvery foliage
• Pollinator-friendly blooms

Lavender works beautifully in borders, pots, paths, and herb gardens.
