How Far Apart Do You Plant Lavender For A Hedge

How far apart you plant lavender for a hedge depends on the variety you choose, but the general rule is 12 to 18 inches apart for a dense, full hedge.
 
If you’re asking how far apart to plant lavender for a hedge, the honest answer is that it’s not a one-size-fits-all number.
 
Different lavender varieties grow at different widths, and the spacing you use will determine how quickly your hedge fills in and how healthy it stays long term.
 
Plant them too far apart and you’ll be staring at gaps for years, but plant them too close and you’ll battle rot, disease, and poor airflow.
 
In this post, we’ll walk through exactly how far apart to plant lavender for a hedge, how to space different varieties, and a few tips to get that tidy, fragrant border you’re dreaming of.
 

How Far Apart to Plant Lavender for a Hedge

When you plant lavender for a hedge, the spacing really comes down to the mature width of the variety and how fast you want the hedge to fill in.
 
Here’s how to think about it so you get the spacing right the first time.
 

1. The General Spacing Rule

As a good starting point, plant lavender 12 to 18 inches apart for a hedge.
 
This range works well for most English lavender varieties, which tend to grow into neat, rounded mounds.
 
If you want your lavender hedge to fill in faster, lean toward the closer end of that range.
 
If you’d rather give each plant more breathing room and you’re patient, go with the wider spacing.
 
Either way, planting lavender 12 to 18 inches apart is the sweet spot most gardeners swear by.
 

2. Spacing by Lavender Variety

How far apart you plant lavender for a hedge also depends on which type you’re growing.
 
English lavender (Lavandula angustifolia) is the classic choice for hedges and usually spreads about 18 to 24 inches wide, so 12 to 18 inches apart works beautifully.
 
French lavender (Lavandula stoechas) grows a bit wider and looser, so you might space those 18 to 24 inches apart to avoid crowding.
 
Spanish lavender tends to be bushier too, so give it a little more room than you would English lavender.
 
If you’re growing a dwarf variety, you can plant lavender closer together, sometimes as tight as 10 to 12 inches apart.
 

3. How Close Is Too Close?

Planting lavender too close together is one of the most common mistakes, and it rarely ends well.
 
Lavender hates sitting in soggy soil, and when plants are crammed together, airflow drops and moisture lingers.
 
That’s a recipe for root rot, fungal disease, and leggy plants that flop open in the middle.
 
So even though you want a full hedge fast, don’t plant lavender closer than about 10 inches apart.
 
Trust the spacing, and your lavender hedge will reward you with years of healthy growth.
 

Tips for Planting a Lavender Hedge

Getting the spacing right is half the battle, but a few other details will help your lavender hedge thrive.
 
Keep these in mind when you plant lavender for a hedge.
 

1. Choose the Right Spot

Lavender needs full sun, so pick a spot that gets at least six to eight hours of direct light each day.
 
Good drainage matters just as much, so if your soil is heavy clay, amend it with grit or plant on a slight mound.
 
When you plant lavender for a hedge, the site you choose matters as much as the spacing.
 

2. Plant in Spring or Early Fall

The best time to plant lavender for a hedge is spring or early fall, when the soil is warm but not scorching.
 
This gives roots time to settle in before extreme heat or cold hits.
 
If you plant lavender for a hedge in the middle of summer, be ready to water more often until it establishes.
 

3. Don’t Skip the Mulch

A light layer of gravel or grit mulch keeps the soil surface dry and keeps weeds down.
 
Avoid heavy organic mulches that trap moisture around the base of the plant.
 
This small step makes a big difference when you plant lavender for a hedge in humid climates.
 

4. Water Deeply but Infrequently

Once established, lavender is drought tolerant and prefers to dry out between waterings.
 
Water deeply at the base rather than splashing the foliage to avoid mildew.
 
Newly planted lavender needs more regular water, but always let the top inch of soil dry first.
 

5. Prune After Flowering

To keep your lavender hedge compact, prune lightly after the first flush of blooms fades.
 
Never cut back into the old woody stems, as lavender rarely regrows from bare wood.
 
A little shaping each year keeps your hedge looking tidy and encourages fresh growth.
 

So, How Far Apart Do You Plant Lavender for a Hedge?

You plant lavender for a hedge 12 to 18 inches apart, adjusting slightly based on the variety and how fast you want it to fill in.
 
Closer spacing gives you a fuller hedge sooner, while wider spacing keeps plants healthier and less prone to rot.
 
Just remember to plant lavender in full sun, in well-draining soil, and never closer than about 10 inches apart.
 
Get the spacing right, and you’ll have a beautiful, fragrant lavender hedge that lasts for years.
