If your lavender is woody, the best thing to do is prune it back hard in early spring to encourage fresh, soft growth from the base of the plant.
Woody lavender is completely normal once plants age, but it doesn’t mean your lavender is dying or beyond saving.
The trick is knowing how and when to cut it so you don’t shock the plant or kill it entirely.
In this post, we’ll look at why lavender gets woody, what you can do about woody lavender plants, and how to stop it happening again.
Why Lavender Gets Woody
Lavender gets woody because it’s a sub-shrub, which means it naturally produces soft new growth on the outside and tough, woody stems toward the center as it matures.
Over time, that woody growth spreads outward, and the plant starts looking bare and leggy in the middle.
Here’s what’s actually going on underneath.
1. Lavender Ages Naturally
Every lavender plant has a lifespan, and as it ages, the older stems harden into wood to support the plant.
This is why a lavender that looked lush and bushy a few years ago can suddenly seem like a woody lavender shrub with just a few green tips.
It’s not a disease, it’s just how lavender grows.
2. Poor Pruning Habits Speed It Up
If you’ve never pruned your lavender, or only trimmed the very tips, the woody base builds up faster.
Lavender needs regular light pruning to keep producing fresh growth from lower down.
Skip that, and you’ll end up with a woody lavender plant much sooner than you’d like.
3. Harsh Winters and Stress Play a Role
Cold snaps, wet soil, and drought all stress lavender out.
When lavender is stressed, it puts energy into surviving rather than pushing out new soft stems, and the wood takes over.
That’s why woody lavender is so common in gardens with tough winters or heavy clay soil.
What To Do If Lavender Is Woody
If your lavender is woody, don’t panic, because there are several ways to bring it back to life.
1. Prune In Early Spring
The best time to deal with woody lavender is early spring, just as new growth starts to appear.
Cut back the woody stems to about two-thirds of their height, but never cut into the old, leafless wood at the very base.
Lavender rarely regrows from bare wood, so leave a few green shoots on each stem.
2. Never Cut Into The Old Wood
This is the golden rule for woody lavender.
If you cut all the way down into the brown, leafless wood, the plant usually won’t send out new growth there.
So always prune back to a point where you can still see green leaves or fresh shoots.
3. Light Pruning After Flowering
After your lavender finishes blooming in summer, give it a light trim.
Just take off the spent flower stalks and about an inch of leafy growth.
This keeps the plant compact and stops it from going woody too fast.
4. Replace Truly Old Plants
If your lavender is more wood than leaf and no amount of pruning helps, it may be time to start again.
Lavender typically lives around 8 to 10 years, and an old, woody lavender plant sometimes can’t be rejuvenated.
Take cuttings from the healthy green growth before you dig it up so you can grow fresh plants for free.
5. Improve Growing Conditions
Woody lavender often signals that the plant isn’t happy where it is.
Lavender loves full sun and well-drained, slightly alkaline soil.
If your soil is heavy or waterlogged, add grit or grow lavender in a raised bed or pot to prevent stress and woody growth.
How To Stop Lavender Going Woody Again
Once you’ve sorted out a woody lavender plant, a little ongoing care keeps it from happening again.
1. Prune Every Year
Set a reminder to prune your lavender every year, once in early spring and once after flowering.
Consistent pruning is the single best way to prevent woody lavender.
2. Don’t Cut Too Low
Always stay in the green growth when you prune.
Going too low into the wood is the fastest way to end up with a woody lavender that won’t recover.
3. Feed Lightly
Lavender doesn’t need rich soil, so go easy on fertilizer.
Too much feeding pushes soft, floppy growth that’s more prone to turning woody and leggy.
4. Water Wisely
Let the soil dry out between waterings and never let lavender sit in soggy ground.
Healthy, unstressed lavender stays greener for longer and produces far less wood.
So, What To Do If Lavender Is Woody?
If lavender is woody, the answer is simple: prune it correctly in early spring, avoid cutting into old wood, and improve its growing conditions.
Woody lavender doesn’t have to be the end of your plant, and with the right care, it can bounce back with fresh green growth.
And if your lavender is simply too old to revive, take cuttings and start fresh so you always have healthy lavender in your garden.
