A lavender tree is not really a tree. It is a lavender plant trained on a single straight stem, with a round, fragrant head of foliage and flowers on top, also known as a lavender standard. On a sunny patio, by a front door or in a formal garden, it brings structure, scent and bees all summer long.
This guide explains how to care for a lavender tree so it stays healthy and shapely for years. You will learn which lavender to choose, why English lavender is often the hardiest choice, what growing lavender in pots requires, how much water and fertilizer it really needs, how pruning lavender keeps the head round, and how to protect a lavender standard in winter.
What Is a Lavender Tree?
A lavender tree, or lavender standard, is a lavender shrub that has been trained to grow on one upright stem. Growers remove the side shoots from the lower stem, support it with a stake and shape the top into a ball. The result looks like a small tree, but the plant is still a lavender shrub with the same needs.
- Elegant, formal shape for patios and entrances
- Flowers at nose height, so you enjoy the scent
- Attracts bees and butterflies
- Works well in pairs on either side of a door or path
- Needs regular pruning to keep the round head
- The single stem is more vulnerable to frost and wind
- Usually grown in a pot, so it needs more attention to watering
- Lasts several years, but eventually gets woody
English Lavender or Another Type: Which Makes the Best Lavender Tree?
| Lavender | Hardiness | Notes |
|---|---|---|
| English lavender (Lavandula angustifolia) | Hardy to about zone 5 | Compact; often blooms twice a year, according to Colorado State University |
| Lavandin (Lavandula x intermedia) | Fairly hardy | Larger plant with one late-summer bloom; strong scent |
| French and Spanish lavender (L. dentata, L. stoechas) | Tender in cold climates | Popular for standards in warm climates; protect from frost or grow as an annual in cold areas |
The University of Illinois Extension names popular English lavender varieties such as Hidcote, Munstead and Twickel Purple, and lavandins such as Phenomenal, which tolerates heat and humidity, and Provence. English lavender is often the best choice where winters are cold. Utah State University Extension lists English lavender for USDA zones 5 to 10. Many lavender trees sold in garden centers are French or Spanish lavender, so check the label and plan winter protection if needed.
How to Care for a Lavender Tree: Sun and Location
- Full sun: at least six hours of direct sun; both Colorado State and Utah State recommend full sun.
- Shelter: a spot out of strong wind, which can snap the single stem or loosen the root ball.
- Airflow: good air movement around the head reduces fungal problems.
- Reflected heat: a south- or west-facing wall or patio suits lavender well.
Growing Lavender in Pots
Most lavender trees are grown in containers. Growing lavender in pots gives you full control over drainage and lets you move the plant into shelter in winter.
| Container tip | Details |
|---|---|
| Pot size | Slightly wider than the head of the tree; at least 12 to 14 inches for a typical standard |
| Weight | A heavy terracotta or stone pot keeps the tree from blowing over |
| Drainage | Large drainage holes; raise the pot on feet |
| Mix | Potting mix with extra grit or perlite for fast drainage |
| Top layer | A layer of gravel keeps the base of the stem dry |
| Repotting | Every two to three years, in spring, into a slightly larger pot |
For more on pots and potting mix, see our guide to container gardening. Lavender combines well with thyme and sage, which like the same dry conditions.
Planting a Lavender Tree in the Ground
- Choose the sunniest, best-drained spot you have; raised beds and slopes are ideal.
- Utah State recommends well-drained soil with a pH of about 6.5 to 7.5; Colorado State notes that lavender grows best in soil with very little organic matter.
- In heavy clay, improve drainage before planting, or plant in a raised bed.
- Plant at the same depth as in the pot and add a sturdy stake.
- Leave 18 to 24 inches between lavender plants, as Utah State advises for English lavender.

How to Water a Lavender Tree
Watering is the part of how to care for a lavender tree where most gardeners go wrong. Lavender is drought-tolerant once established, and too much water quickly leads to root rot.
| Situation | How often |
|---|---|
| Newly planted | Once or twice a week until established; Utah State suggests about 1 gallon per plant per week |
| Established, in the ground | Every two to three weeks until buds form, then once or twice a week through flowering |
| In a pot, in summer | When the top 1 to 2 inches of mix are dry; check every few days |
| In winter | Sparingly; keep the root zone barely moist and never waterlogged |
Water at the base of the plant, not over the flowers and leaves. A hose with a gentle, adjustable nozzle helps you water the pot precisely; see our garden hose nozzle guide. For general watering advice, see how often to water your garden.
Feeding: Less Is More
Utah State University notes that lavender has low nutritional needs and that over-fertilized plants produce more foliage but fewer flowers.
- In the ground: a little compost at planting is usually enough for the first year.
- In pots: one light application of slow-release fertilizer in spring, or a diluted liquid feed once or twice in summer.
- Avoid high-nitrogen fertilizers, which make the head soft and floppy.
Pruning Lavender to Keep the Round Head
If you want to know how to care for a lavender tree so it keeps its shape, pruning lavender is the key to a dense, round lavender tree that does not turn woody. Utah State recommends pruning every year after flowering, and Colorado State advises pruning when green growth appears at the base, removing about a third of the top.
Sharp hand shears or pruners make clean cuts; see our gardening tool sets guide.
Caring for the Trunk, Stake and Suckers
- Keep the stake in place for the life of the tree; the single stem is easily snapped by wind.
- Check ties twice a year and loosen them so they do not cut into the stem.
- Rub off or cut any shoots that grow from the trunk or the base, so all energy goes to the head.
- Keep mulch and gravel away from direct contact with the stem.
Harvesting Lavender Flowers
You can enjoy the flowers on the tree, or cut some for drying. Colorado State advises harvesting in mid-morning when about half of the flower buds have opened; Utah State suggests picking when the first two flowers on a spike have opened, after the dew has dried.
- Cut long stems, which also helps keep the head tidy.
- Tie small bunches with rubber bands and hang them upside down in a dark, airy place.
- Use dried lavender in sachets, wreaths and arrangements.
Winter Care for a Lavender Tree
| Situation | What to do |
|---|---|
| English lavender in the ground (cold-hardy areas) | Usually survives; a well-drained spot is more important than extra cover |
| Lavender tree in a pot | Move it against a sheltered wall or into an unheated, bright garage or shed during hard frosts |
| French or Spanish lavender in cold areas | Bring indoors to a cool, bright room, or treat as an annual |
| Wet winters | Raise pots on feet and keep them out of standing water |
| Wind and heavy snow | Colorado State suggests fabric row covers to protect young plants |
The University of Illinois notes that dampness kills lavender more often than cold, recommends gravel around the crown, and advises waiting until new growth appears in spring before pruning. Water potted lavender very sparingly in winter. See our guide to winterizing your garden for more frost protection tips.
How to Make Your Own Lavender Standard
Propagating Lavender
Colorado State University explains that lavender roots easily from cuttings of non-flowering stems taken after bloom; strip the lower leaves and insert the cuttings in clean potting mix or vermiculite, and roots form in about three weeks without rooting hormone. Utah State notes that most lavender is propagated from cuttings because seed is slow.
Rooting a few cuttings is a great way to start a new lavender tree or to replace an older one.
Lavender Tree Problems and Solutions
| Problem | Likely cause | Solution |
|---|---|---|
| Yellow or gray, wilting plant | Root rot from wet soil (Utah State lists Phytophthora root rot) | Improve drainage; water less; repot in gritty mix |
| Woody, bare head | No annual pruning, or cuts into old wood | Prune every year after flowering, staying in green growth |
| Few flowers | Too much shade or fertilizer | Move to full sun; feed less |
| Floppy, open head | Too much water or nitrogen; not enough sun | Reduce water and feeding; prune into shape |
| Tree leans or snaps | Loose stake, wind | Re-stake; move to a sheltered spot |
| Spittlebug foam or aphids | Sap-sucking insects | Rinse off with water; see our white bugs guide |
See white bugs on plants and our garden insects guide.
Styling Ideas for a Lavender Tree
- A matching pair of lavender trees on either side of a front door or garden gate.
- A row of lavender standards along a sunny path or terrace.
- Underplant the pot with creeping thyme or trailing rosemary.
- Combine with gray and silver plants such as sage and santolina for a Mediterranean look.
- Place it near your outdoor seating, where you can enjoy the scent.

Frequently Asked Questions
Can I keep a lavender tree indoors?
Only for short periods. Lavender needs full sun and good airflow, which most homes cannot provide. Keep it outside in summer and move it to a cool, bright, frost-free place in winter if needed.
When does a lavender tree bloom?
Usually in early to midsummer. English lavender often blooms a second time later in the season, especially after pruning.
How do you care for a lavender tree?
Give it full sun, a pot or soil with excellent drainage, water only when the top inch or two is dry, feed very little, prune after flowering and protect it from hard frost and winter wet.
Is a lavender tree a real tree?
No. A lavender tree is a lavender shrub trained on a single stem, also called a lavender standard.
How often should I water a lavender tree in a pot?
When the top 1 to 2 inches of mix are dry. In summer, that may be every few days; in winter, much less often.
When should I prune a lavender tree?
After the main flowering in summer, trim off spent flowers and shape the head by about a third. Tidy frost-damaged tips in spring, and never cut into old, bare wood.
Can a lavender tree stay outside in winter?
English lavender standards can stay outside in many areas if the pot drains well and is sheltered. French and Spanish lavender should be protected from frost or brought into a cool, bright room.
Why is my lavender tree turning brown?
Usually because of wet roots and root rot. Other causes are frost damage, drought in a small pot or old, woody growth.
Which lavender is best for a lavender tree?
English lavender is the hardiest choice in cold climates. French and Spanish lavender are popular in warm climates but need frost protection elsewhere.
Does a lavender tree need fertilizer?
Very little. Too much fertilizer gives soft growth with fewer flowers. A small amount of slow-release fertilizer in spring is enough for pots.
How long does a lavender tree live?
With good drainage and yearly pruning, a lavender standard can stay attractive for several years before it becomes too woody.
Is growing lavender in pots better than in the ground?
For lavender trees, pots are often easier, because you control drainage and can move the plant to shelter in winter.
Do lavender trees attract bees?
Yes. Lavender flowers are very attractive to bees and butterflies, which makes a lavender tree a great addition to a pollinator-friendly patio.
Final Thoughts
Now you know how to care for a lavender tree: give it full sun and excellent drainage, water sparingly, feed very little and protect it from winter wet and hard frost. Choose English lavender for the best winter hardiness.
With regular pruning lavender after flowering, a well-staked stem and the right approach to growing lavender in pots, your lavender standard will stay compact, fragrant and full of flowers for years.
