How to Grow Lavender: A Beginner's Guide for Gardens & Pots
Lavender has a reputation for being difficult in cold or humid climates. The plant would like to clarify: it is not difficult; it is specific. Give it sun, air and fast drainage, and it will tolerate lean soil and the occasional forgotten watering. Give it shade and a damp crown, and it will begin composing its farewell letter.
This beginner's guide covers the entire path from choosing a cultivar to pruning a mature plant. It is written for Great Lakes gardens, but the principles travel well.
1. Choose the right lavender
Use the Great Lakes USDA Zone Finder, then confirm the exact cultivar listing.
- English lavender (Lavandula angustifolia) includes compact, hardy favorites such as 'Hidcote,' 'Munstead,' 'Vera,' 'Essence Purple' and pink-flowered 'Melissa.' It is often the first group for cold gardens.
- Lavandin (Lavandula x intermedia) includes larger, long-stemmed cultivars such as 'Grosso' and Phenomenal. These are popular for bundles, fragrance and landscape impact.
- Spanish and French lavenders offer ornamental bracts or foliage but are less cold hardy. In Michigan, grow them as seasonal or protected container plants.

2. Find the sunniest dry site
Lavender needs at least six to eight hours of direct sun. More sun generally produces denser growth and better bloom. Choose open air movement without placing the plant in a winter wind tunnel.
Drainage is the deciding condition. Michigan State University Extension recommends sandy loam, good drainage and a pH around 6.5 to 8 for lavender in Michigan. Test soil before applying lime. Observe the site after heavy rain and spring thaw.
If the soil remains wet, use a properly built raised bed or berm, improve field drainage or choose a container. Do not bury a scoop of gravel beneath the root ball; a gravel sump under clay still holds water, now with decorative stones.
3. Pick the plant size that matches your experience
Great Lakes Lavender Farm may offer:
- 72-cell and deep 20-cell plugs for growers and larger plantings.
- A 3-inch plug for an economical garden start.
- A fuller 4-inch pot for easy retail transplanting.
- A 1-gallon plant for immediate presence.
- Two-plus-year bare-root lavender for eligible spring planting.
Beginners often succeed fastest with a 4-inch or 1-gallon plant because the root system is easier to manage. Plugs are excellent value when you can monitor small root volumes closely.
4. Plant without burying the crown
Plant after the site is prepared and the weather offers a reasonable establishment window.
- Water the container before planting.
- Dig a hole wider than the root ball, but not needlessly deeper.
- Loosen tightly circling roots.
- Set the crown at the same level it grew in the pot. For bare root, set the crown even with the soil line and spread roots downward.
- Backfill with prepared soil and firm gently.
- Water thoroughly to settle the root zone.
- Keep bark, compost and fallen leaves away from the woody crown.
Space plants by mature spread. Compact English lavender may need roughly 18 to 24 inches; large lavandins may need 30 to 36 inches or more. Check the cultivar listing.
5. Water for establishment, then ease off
New plants need regular observation. Water deeply when the root zone approaches dry, then let excess water drain. Hot, windy container plants dry faster than an established plant in the ground.
Once rooted, lavender is drought tolerant. That does not mean it never needs water; it means the plant dislikes constant moisture more than occasional dryness. Drip irrigation is helpful for rows and beds because it targets roots without routinely wetting foliage.
Symptoms can mislead. Both overwatering and underwatering can cause wilt. Put a finger or probe into the root zone before deciding. If the soil is wet and the plant is wilted, the solution is rarely another gallon.
6. Feed lightly
Lavender performs well in lean soil. Too much nitrogen produces lush foliage, fewer flowers and soft growth. Use a soil test in the garden and a measured program for containers. Do not add bone meal, lime or fertilizer automatically at planting.
Container lavender eventually needs nutrients because irrigation leaches the medium, but use a light, balanced approach and follow the media or fertilizer guidance. A larger dose does not create a larger virtue.
7. Prune while the plant is green
Lightly shape young plants to encourage branching. After bloom, remove flower stems and trim leafy growth into a rounded mound. Avoid cutting hard into old, bare wood; many lavenders do not reliably regrow from it.
In cold zones, avoid severe late-fall pruning. Wait until spring growth shows what survived, then remove dead tips and shape. A little annual pruning is safer than waiting until the plant becomes a woody octopus and negotiating all at once.
Grow lavender in a container
Choose a pot with generous drainage holes and a fast-draining commercial medium. Terracotta dries quickly; glazed and plastic pots retain moisture longer. Size the container for the mature plant and repot when roots fill it.
Place the pot in full sun and raise it so holes cannot seal against the surface. Empty saucers after watering. In cold climates, protect the root ball from extreme temperature swings in a bright, cool, ventilated location. Hardy in the ground does not mean equally hardy in a pot.
Harvest at the stage your project needs
- For dried bundles, cut when buds are colored and the first florets begin to open.
- For fresh flowers, cut when the spike looks full but remains firm.
- For loose buds, earlier harvest often retains color and reduces shatter.
- For pollinators, leave a portion to bloom fully.
Cut on a dry day after dew has evaporated. Bundle loosely and dry in shade with good airflow. Label the cultivar and date.
For cooking, use only correctly identified culinary lavender grown without inappropriate pesticides. English lavender is generally preferred for its sweeter flavor. Essential oil is concentrated and is not a casual replacement for flower buds.
Winter care in the Great Lakes
Clear wet debris from crowns, correct drainage and avoid heavy organic mulch. Use a breathable cover over a frame only where zone and exposure justify it. Snow can insulate; ice and meltwater can injure wet crowns.
Use the Frost Date Estimator (coming soon) for local planning and record the result in My Lavender Garden. The plant's response to your own microclimate is the best guide for next season.
Great Lakes Lavender Farm ships eligible live plants March 1 through May 31 and October 1 through November 30. Bare root ships March 1 through May 31. Live-plant shipping pauses during summer, while arranged local pickup may remain available.
Frequently asked questions
Does lavender come back every year?
Hardy lavender is perennial when the cultivar matches the zone and the site drains well. Tender types may be annuals in cold climates.
Can lavender grow indoors?
Long-term indoor growth is difficult because lavender needs very high light and airflow. A bright outdoor container with protected winter care is usually more successful.
Why is my lavender turning yellow?
Check soil moisture and drainage first. Wet roots, a buried crown, dense mulch and low light are common causes. Do not fertilize until the cause is understood.
How long does lavender live?
Longevity varies by species, cultivar, climate and pruning. Good drainage and regular light shaping help extend useful life; commercial fields are replanted in stages as production declines.
