How to Grow Lavender

Lavender is a beautiful, fragrant herb valued for its purple flowers, silvery foliage, and ability to thrive in sunny, relatively dry conditions. It works well in herb gardens, flower beds, borders, containers, rock gardens, and pollinator gardens. Once established, lavender is relatively low-maintenance, but it does require the right soil, drainage, sunlight, and watering practices.

This growing guide explains how to grow lavender successfully, including planting, watering, fertilizing, pruning, harvesting, propagation, and winter care.

Lavender at a Glance

Choosing a Location for Lavender

The most important factor when growing lavender is choosing a suitable location. Lavender needs full sun and excellent drainage.

Choose a location that receives at least 6 hours of direct sunlight per day, although more sunlight is generally beneficial. Plants grown in insufficient light may become weak, stretched, and less productive.

Good locations include:

• Sunny herb gardens
• Raised beds
• Rock gardens
• Gravel gardens
• Sunny borders
• Containers with drainage holes
• Sloping areas where water drains naturally

Avoid planting lavender in low areas where rainwater collects. Constantly wet soil is one of the most common reasons lavender plants decline.

Good air circulation is also helpful, particularly in humid climates. Give mature plants enough space that foliage does not remain crowded and damp after rainfall.

Soil Requirements

Lavender performs best in well-drained soil. It does not need highly fertile soil and often performs better in moderately lean soil than in heavily fertilized garden beds.

Heavy clay soil can be problematic because it holds water around the roots. If your garden has poorly drained clay, consider growing lavender in a raised bed or container rather than trying to maintain it in saturated ground.

Before planting, improve drainage where necessary by incorporating suitable organic material and creating raised planting areas. Avoid creating a small pocket of highly amended soil surrounded by heavy clay, because water can collect around the amended planting hole.

Lavender generally prefers soil that is neutral to slightly alkaline. Extremely acidic soil may be less suitable for vigorous growth.

A soil test can help determine whether your planting area needs amendments.

Planting Lavender

Spring is usually an excellent time to plant lavender because plants have the entire growing season to establish their root systems.

Choose healthy plants with vigorous green or gray-green foliage and no obvious signs of disease.

How to Plant Lavender

1. Select a sunny location with excellent drainage.
2. Dig a planting hole slightly larger than the root ball.
3. Remove the plant carefully from its container.
4. Loosen circling roots if necessary.
5. Set the plant at approximately the same depth at which it was growing in its container.
6. Backfill with the native soil.
7. Water thoroughly after planting.
8. Allow the soil to dry somewhat between subsequent waterings.

Do not bury the crown or stems deeply. Planting too deeply can increase the risk of rot.

Lavender Spacing

Spacing depends on the variety and the desired appearance of the planting.

Smaller varieties may be planted approximately 18 inches apart, while larger plants may require 24–36 inches or more.

Allow enough room for mature plants to develop without becoming overcrowded.

Growing Lavender in Containers

Lavender grows well in containers as long as drainage is excellent.

Choose a container with drainage holes and use a well-draining potting mix. Avoid heavy mixes that remain wet for extended periods.

Terracotta pots can work particularly well because they allow some moisture to evaporate through the sides.

Container-grown lavender usually requires more frequent monitoring than plants growing in the ground because containers dry out faster. However, avoid responding to dry surface soil by automatically watering every day. Check the moisture deeper in the container before watering.

During winter, containers may require additional protection because roots are more exposed to freezing temperatures than roots of plants growing in the ground.

Watering Lavender

Newly planted lavender needs regular watering while its root system becomes established. Once established, however, lavender is relatively drought tolerant.

The goal is to provide enough moisture for healthy growth without keeping the soil continuously wet.

Water deeply when the plant needs moisture rather than giving it frequent shallow waterings.

Established lavender generally prefers the soil to dry somewhat between waterings. The exact watering frequency depends on:

• Temperature
• Rainfall
• Soil type
• Container size
• Plant size
• Humidity
• Drainage

In humid or rainy climates, the bigger concern may be excess water rather than drought.

Water at the base of the plant when possible and avoid repeatedly wetting the foliage.

Fertilizing Lavender

Lavender generally does not require heavy fertilization.

Excessive nitrogen can encourage soft, leafy growth at the expense of compact growth and flowering. Heavy fertilization can also make plants more susceptible to problems associated with excessive moisture and weak growth.

If your soil is reasonably fertile, a light application of a balanced fertilizer in spring may be sufficient, and in some gardens fertilizer may not be necessary at all.

A soil test is the best way to determine whether nutrients are actually lacking.

Mulching Lavender

Mulching can help suppress weeds and moderate soil temperatures, but mulch should be used carefully around lavender.

Avoid piling thick, moisture-retaining organic mulch directly against the plant's crown. In wet climates, this can contribute to poor air circulation and rot.

A thin layer of coarse material, such as gravel, can be useful around lavender because it allows the soil surface to remain relatively dry while helping suppress weeds.

Keep mulch away from the base of the plant.

Pruning Lavender

Regular pruning helps lavender maintain a compact, attractive shape and can prevent plants from becoming excessively woody.

The timing and amount of pruning depend on the type of lavender and your climate.

After flowering, spent flower stems can be removed. Light shaping can also be performed to maintain the plant's form.

Avoid cutting deeply into old, leafless woody stems. Lavender does not always regenerate reliably from old wood.

A good rule is to remove green, leafy growth while avoiding severe cuts into the oldest woody portion of the plant.

Should Lavender Be Cut Back in Fall?

This depends on your climate and the type of lavender you grow.

In areas with cold winters, heavy pruning in late fall can leave plants more vulnerable to winter damage. In those areas, it is often preferable to perform major shaping after flowering or in spring once new growth begins.

In mild climates, lavender can generally be pruned more routinely.

Harvesting Lavender

Lavender is commonly harvested for dried flowers, sachets, crafts, culinary uses, and fragrance.

For many uses, the best time to harvest the flower stems is when the buds have developed and some flowers are beginning to open.

Harvesting in the morning after dew has dried but before intense afternoon heat can help preserve fragrance.

How to Harvest Lavender

1. Use clean, sharp scissors or pruning shears.
2. Cut flower stems above the woody portion of the plant.
3. Gather stems into small bundles.
4. Remove damaged foliage.
5. Hang bundles upside down in a dry, dark, well-ventilated location.
6. Allow the flowers to dry completely before storing.

Avoid packing freshly harvested lavender tightly together because trapped moisture can encourage mold.

Propagating Lavender From Cuttings

Cuttings are often a practical way to produce new lavender plants that are genetically identical to the parent plant.

Take healthy non-flowering shoots and remove the lower leaves. Insert the cuttings into a sterile, well-draining propagation medium and keep the medium lightly moist.

Bright, indirect light and moderate humidity can encourage rooting.

Once the cuttings have developed a strong root system, they can be transplanted into individual containers and gradually acclimated to outdoor conditions.

Growing Lavender From Seed

Lavender can be grown from seed, although seed-grown plants may take longer to reach flowering size and may not produce plants identical to a particular parent plant.

Some lavender species and types have specific germination requirements, so follow the recommendations supplied with the seed.

Start seeds in a well-draining seed-starting medium and provide bright light after germination. Avoid keeping the seedlings constantly wet.

Seed propagation can be particularly useful when growing species rather than trying to reproduce a specific named cultivar.

Common Lavender Types

Several different types of lavender are commonly grown by gardeners.

English Lavender

English lavender (Lavandula angustifolia) is one of the most widely grown types. It is valued for its fragrance, flowers, and relatively good cold tolerance compared with some other lavender types.

Lavandin

Lavandins are hybrids involving English lavender and spike lavender. They often produce large plants with long flower stems and abundant flowers.

Spanish Lavender

Spanish lavender (Lavandula stoechas) is recognized by its distinctive flower heads topped with showy bracts. It generally prefers warmer conditions and may be less winter hardy than English lavender.

French Lavender

The common name "French lavender" can refer to different lavender species depending on the region and nursery, so checking the botanical name is useful when selecting plants.

Common Lavender Problems

Root Rot

Root rot is one of the most serious problems affecting lavender.

Symptoms may include:

• Wilting despite wet soil
• Yellowing foliage
• Brown or black roots
• Declining branches
• Plant death

The best prevention is excellent drainage and avoiding excessive watering.

Leggy Growth

Lavender can become open and leggy when grown in insufficient sunlight or when it is not pruned appropriately.

Move container plants to a sunnier location when possible and provide adequate spacing between plants.

Woody, Unproductive Plants

Older lavender plants naturally develop woody stems. Severe cutting into old wood may not produce vigorous new growth.

Regular light pruning while plants are young can help maintain a compact structure.

Gray or Moldy Foliage

Persistent moisture, poor air circulation, and humid conditions can encourage fungal problems.

Improve spacing, avoid unnecessary overhead watering, and remove severely affected plant material.

Lavender and Pollinators

Lavender flowers are attractive to many pollinating insects, including bees and butterflies.

Planting lavender alongside other flowering herbs and perennials can provide valuable forage throughout the growing season.

For a pollinator-friendly garden, avoid unnecessary insecticide applications while lavender is flowering.

Winter Care

Winter hardiness varies considerably among lavender types.

English lavender is generally more cold tolerant than many warm-climate lavender species and hybrids, but hardiness also depends on the cultivar and growing conditions.

In cold climates:

• Avoid excessive fall watering.
• Ensure the soil drains well.
• Avoid heavy pruning immediately before winter.
• Protect container-grown plants from severe cold.
• Use a well-drained sheltered location when possible.

Do not wrap lavender so tightly that moisture becomes trapped around the plant.

Troubleshooting Lavender

Tips for Growing Healthy Lavender

• Plant lavender in full sun.
• Prioritize excellent drainage over highly fertile soil.
• Allow the soil to dry somewhat between waterings.
• Avoid heavy nitrogen fertilization.
• Give plants adequate space for good air circulation.
• Prune regularly without cutting deeply into old wood.
• Harvest flowers when buds are developed and beginning to open.
• Choose lavender types suited to your climate.
• Use containers with excellent drainage.
• Avoid keeping lavender in constantly wet soil.

Final Thoughts

Lavender is relatively easy to grow when its basic requirements are met. The key is to think of it as a plant that prefers sun, drainage, and relatively dry conditions rather than a typical moisture-loving garden perennial.

Give lavender plenty of sunlight, avoid overwatering, provide well-drained soil, and prune it carefully to maintain a compact shape. With the right growing conditions, lavender can provide fragrant flowers and attractive foliage for many years while also adding beauty and pollinator value to the garden.
