Does lavender get bigger every year?
Yes, lavender does get bigger every year, but only up to a point.
It’s a perennial plant, so it comes back season after season, and each year it puts on new growth that makes it wider and fuller.
That said, lavender doesn’t grow endlessly like some trees or shrubs do.
It has a natural size limit, and how big it gets depends on the variety you’re growing and how well you care for it.
In this post, we’ll look at whether lavender gets bigger every year, how much growth you can expect, and what you can do to keep your plant healthy as it matures.
Let’s dig in.
Why Lavender Gets Bigger Every Year
Lavender gets bigger every year because it’s a woody perennial that keeps producing new stems and foliage during each growing season.
Here’s what’s happening under the surface:
1. It’s a Perennial That Returns Each Season
The main reason lavender gets bigger every year is that it’s a perennial, not an annual.
Annuals complete their life cycle in one season and die off, but lavender sticks around.
Each spring, it wakes up from its winter dormancy and pushes out fresh growth from the base and from existing stems.
That new growth adds mass, so the plant gradually expands year after year.
2. New Stems Keep Emerging From the Base
Lavender produces new shoots from the crown of the plant, which is the area right where the stems meet the soil.
As those shoots mature, they turn woody and add to the overall structure.
This is why a lavender plant that looked small in its first year can double in size by its second or third year.
The root system also expands underground, supporting more top growth.
3. Mature Plants Fill Out Quickly
Once lavender hits its second or third year, it really starts to fill out.
The plant becomes bushier, and the spread widens as side branches develop.
By the time it’s fully established, usually around year three to five, you’ll notice it’s noticeably bigger than when you first planted it.
After that, growth slows down quite a bit.
How Much Bigger Does Lavender Get Each Year?
How much bigger lavender gets every year depends on the type you’re growing and your climate.
Here are some general guidelines:
1. English Lavender (Lavandula angustifolia)
English lavender typically grows to about 2 to 3 feet tall and wide at maturity.
In its first year, it might only reach 8 to 12 inches.
By year two, it can double in size, and by year three, it’s usually close to its full spread.
2. French and Spanish Lavender
French and Spanish lavenders tend to be larger, often reaching 3 to 4 feet in height and spread.
They also grow faster in warm climates, so you might see them get bigger every year more dramatically than English types.
3. Dwarf Varieties Stay Compact
Dwarf lavender varieties like ‘Hidcote’ or ‘Munstead’ stay smaller, usually maxing out around 12 to 18 inches.
They still get bigger every year, but their growth plateaus sooner.
Does Lavender Stop Growing at Some Point?
Yes, lavender does stop getting bigger at some point.
Once it reaches maturity, usually around year three to five, growth slows significantly.
At that stage, the plant focuses more on maintaining its size and producing flowers rather than expanding.
In fact, if lavender gets too woody and leggy, it can actually start to decline.
That’s why regular pruning is so important.
Pruning keeps the plant compact, encourages fresh growth, and prevents it from getting too sparse in the middle.
Without pruning, lavender can become woody and stop producing as much new growth, which means it won’t get bigger every year the way a well-cared-for plant would.
How to Encourage Healthy Growth in Lavender
If you want your lavender to get bigger every year in a healthy way, here’s what to do:
1. Give It Full Sun
Lavender needs at least six to eight hours of direct sunlight daily.
Without enough sun, it grows leggy and weak instead of bushy and full.
2. Plant in Well-Draining Soil
Lavender hates wet feet.
Soggy soil leads to root rot, which can kill the plant before it ever gets the chance to get bigger every year.
Mix in sand or gravel if your soil holds too much water.
3. Prune After Flowering
Cut back about one-third of the plant after it finishes blooming.
This keeps it from getting too woody and encourages fresh growth the following season.
Just avoid cutting into the old wood, as it often won’t regrow from there.
4. Don’t Overfertilize
Lavender doesn’t need much fertilizer.
Too much nitrogen makes it grow soft and floppy instead of compact and sturdy.
A light dose of compost in spring is usually plenty.
So, Does Lavender Get Bigger Every Year?
Lavender does get bigger every year, but only until it reaches maturity.
After that, it plateaus and needs regular pruning to stay healthy and full.
So if you’re wondering whether your lavender will keep expanding, the answer is yes, up to a point.
Give it plenty of sun, well-draining soil, and a good pruning routine, and you’ll enjoy a lavender plant that gets bigger every year and stays beautiful for many seasons to come.
