Growing Lavender

Try growing lavender in your home garden. It makes a wonderful border, grows well in pots, and smells terrific for sachets, salts, and cooking.

Growing Lavender

The countryside of southern France is legendary for its fields of lavender (Lavandula x intermedia Provence) grown for the perfume industry. In North America, lavender is a shrubby perennial grown for its flowers and fragrance, but it also serves as a landscape item for its beauty and ability to stand heat and drought. In parts of California, is it used in islands of commercial parking lots, which attests to its toughness.

In a formal garden, lavender may be clipped to form a low hedge or an aromatic border along a path. In a rock garden, a single plant or just a few plants may be used to great effect as an accent. And, of course, lavender is a natural choice for any herb garden. The cool, gray-green foliage contrasts nicely with its own flowers, as well as dark green herbs and other plants.

Lavender also grows quite well in containers. In the Deep South, it actually does better in pots, as it benefits from improved drainage and air circulation. While the plants thrive in arid Western climates, they are usually considered annuals in the South.

Quick Guide to Growing Lavender

  • Plant lavender in spring, once all chances of frost have passed. This beautiful, fragrant herb is a great addition to raised beds, in-ground gardens, and growing in containers.
  • Space lavender plants 12 to 18 inches apart in an area with plenty of sunlight and sandy, well-drained soil with a pH of 6.7 to 7.3.
  • Give young plants an excellent start to the growing season by mixing in several inches of compost or other rich organic matter into your native soil.
  • Lavender survives well in dry conditions, so you'll only have to water when the top 2 inches of soil are dry.
  • Promote vibrant blooms by regularly feeding with water-soluble plant food.
  • Harvest stems once they're large enough for use. Avoid harvesting more than one-third of the plant at a time.

Soil, Planting, and Care

Set plants 12 to 18 inches apart in an open area with full sun and good air circulation. Be sure to choose strong, vigorous young lavender plants, like those from Bonnie Plants®. Bonnie has been growing plants for the home gardener for over a century, so you can rely on us to help you be successful.

Plant lavender in well-drained, slightly alkaline soil with a pH between 6.7 and 7.3. You can add builder's sand to the soil before planting to increase drainage, which is vital because lavender will not tolerate excessive soil moisture or humidity. To further improve drainage, plant lavender in a raised bed filled with premium raised bed soil, such as Miracle-Gro® Performance Organics® Raised Bed Mix, along a wall, or near the top of a slope. In an herb or perennial bed, ensure good drainage by planting lavender on a small mound. When planting lavender in pots, be sure to use high quality potting mix, such as blogs/garden-fundamentals/pollination-problems-give-hand-pollination-a-try. For the very best results—think lots of beautiful, fragrant blooms—it's also important to feed lavender regularly with a premium plant food like Miracle-Gro® Performance Organics® Blooms Plant Nutrition. Be sure to follow the directions on the label.

Lavender flowers bloom in summer; you can clip faded blooms to encourage continued blooming throughout the warm season. Prune lightly to promote branching, especially in spring once the plants show new growth.


Remember that lavender needs good drainage and good air circulation. Do not over-water, and allow the soil to dry before watering again. When there is a lot of heat and humidity, fungus can attack the plants, turning the leaves brown. To minimize the chance of having such a problem, mulch with pebbles or sprinkle sand around the base of the plant for faster evaporation. If you cut the blooms, trim in a way that thins the plant a bit, leaving it open for better air circulation.

Start your transplants out in pretty containers, especially in humid climates where good air circulation is a must.
When you cut lavender blossoms, leave a long stem attached for handling.

Harvest and Storage

Harvest lavender stems at any time by cutting them from the plant. However, avoid clipping more than every third stem to keep the plant looking full. Flowers will keep their perfume for months when you harvest just before they are entirely open. To dry flowers, gather a bunch of stems and hang them upside-down in a dark, well-ventilated place to preserve colour and keep the stems from molding.


Fresh flowers may be used in sauces, marinades, and desserts. Handle fragile dried blossoms with care and use them in teas, salts, potpourri, sachets, and crafts.


What is the secret to growing lavender?

Lavender needs full sun and good drainage. It is more likely to die from excess moisture than from cold in winter. A pot is an excellent way to provide drainage, though the plant will be more vulnerable to cold temperatures than it would be in the ground.

Can I grow lavender in a container?

Absolutely! If you live in a moist or humid region, a container may be the only way to give your plant adequate drainage and sufficient air circulation to prevent rot. While lavender thrives in the dry, arid climate of the Provence region of France and in sunny California gardens, it may turn brown from fungal infection as the result of too much moisture in regions with higher rainfall and humidity. A terra cotta pot filled with a quality potting mix is ideal. Also, lavender grows best at a slightly alkaline pH of 6.7 to 7.3. Most potting soils are slightly acidic, so you may wish to mix lime into the soil at the rate of 2 to 3 ounces per cubic foot of potting mix. Also, when fertilizing, opt for timed-release granules or a product providing the nitrate form of nitrogen.

I have never planted lavender before and need some information about its habits. How much is it likely to spread?

Lavender is a small shrub that usually grows 20 to 24 inches tall and wide. The height includes the flower stalks, so when not in bloom, the foliage may be only a foot tall. The plant does not spread as thyme, oregano, and other herbs tend to. Whether the plant will grow to its greatest potential size also depends on growing conditions.

I just purchased lavender. Can I use it in cooking?

Yes. It lends a delicate floral essence to both teas and desserts. In the latter, the flower are usually combined with a liquid ingredient in which their fragrant oil is released. Then the flowers themselves are strained from the cream, honey, or other carrier of the flavor.

My plants look great and are growing but not flowering. Any suggestions?

Lavender is a perennial herb in many areas - that is, perennial if it gets really good drainage. Growing in a pot is an ideal way to provide good drainage. However, if the potting mix is extremely fertile, the plant may grow leaves and stems rather than flowering. Cut back on your fertilizer, especially if it is high in nitrogen. You can try switching to a bloom-booster formulation, or simply stop feeding it for a few weeks.

What is the best way to keep lavender plants over the winter?

Lavender plants are a challenge to grow in areas of high rainfall, particularly in winter. Many gardeners in the Southeast consider lavender an annual. Be sure to plant lavender in a pot, raised bed, or atop a retaining wall. Given sufficient drainage, plants will be winter hardy in zone 5 and areas that are warmer. If grown in a pot, lavender will need some protection during winter in zone 5 and areas that are colder.

Can one lavender plant be split into several in the springtime?

No. Unlike herbs that spread into clumps with underground or above-ground stems, lavender is a woody shrub and does not form a clump.
