You can plant lavender for a hedge about 12 to 18 inches apart for a tight, formal look, or 18 to 24 inches apart if you want a looser, more natural hedge.
That spacing gives the plants enough room to breathe, spread their roots, and knit together into a continuous wall of color without overcrowding each other.
So if you’ve been wondering how close to plant lavender for a hedge, the short answer is closer than most people think, as long as the soil drains well and you pick the right variety.
In this post, we’ll look at how close to plant lavender for a hedge, the factors that change that spacing, and how to get your hedge looking full and healthy from the first season.
How Close to Plant Lavender for a Hedge
How close to plant lavender for a hedge depends on the variety you choose and the look you’re after.
As a general rule, plant lavender 12 to 18 inches apart to create a dense hedge that fills in fast.
If you’re working with a larger variety, plant lavender for a hedge at around 18 to 24 inches apart.
This gives each plant room to reach its mature width without the roots fighting for water and nutrients.
Here’s how to think about how close to plant lavender for a hedge based on your goals:
1. Tight, Formal Hedge Spacing
If you want a crisp, manicured hedge, plant lavender closer together at about 12 inches apart.
The plants will grow into one another quickly, forming a solid line you can shear into shape.
Just keep in mind that tight spacing means better airflow matters even more, so make sure the soil drains freely.
Tight spacing is great for low hedges along a path or the front of a border.
It’s also the answer to how close to plant lavender for a hedge when you want results within a single season.
2. Looser, Natural Hedge Spacing
For a softer, cottage-garden feel, plant lavender for a hedge about 18 to 24 inches apart.
This spacing lets each plant keep its natural mounded shape.
You’ll see small gaps between plants early on, but they’ll close up as the lavender matures.
It also reduces the risk of disease because air moves freely through the hedge.
If you’re unsure how close to plant lavender for a hedge and want lower maintenance, this is the spacing to pick.
3. Spacing for Larger Varieties
Bigger lavender types like ‘Grosso’ or ‘Provence’ can spread 2 to 3 feet wide.
For these, how close to plant lavender for a hedge should be closer to 24 inches, or even a bit more.
Crowding a large variety only leads to weak, woody plants and poor flowering.
So match your spacing to the mature size on the plant tag, not the size of the little pot you bought.
Factors That Change How Close to Plant Lavender for a Hedge
Several things can shift the ideal spacing, so let’s run through the big ones.
Getting these right means your hedge will thrive no matter how close to plant lavender for a hedge you decide to go.
1. Lavender Variety
English lavender stays compact, often 18 to 24 inches wide, so it can sit closer together.
French and Spanish lavenders are larger and looser, so they need more room.
Knowing your variety is the first step to deciding how close to plant lavender for a hedge.
2. Soil and Drainage
Lavender hates wet feet, so soil drainage matters as much as spacing.
In sandy, fast-draining soil, you can plant lavender for a hedge a little closer.
In heavy clay, give plants more space and amend the soil so water never sits around the roots.
3. Climate and Sunlight
In hot, dry climates lavender grows fast and wide, so plant lavender for a hedge farther apart.
In cooler zones, growth is slower and plants stay smaller, so you can tuck them in closer.
Either way, aim for at least six hours of full sun for the strongest hedge.
4. Your Hedge Goals
A low border hedge can be planted close for instant impact.
A taller, more relaxed hedge looks better with wider spacing.
So how close to plant lavender for a hedge really comes down to the look you want and how patient you are.
Tips for Planting Lavender as a Hedge
Once you know how close to plant lavender for a hedge, a few extra steps will set your hedge up for success.
Start with well-drained soil, and if you’re on clay, build a raised bed or mound.
Dig a hole twice as wide as the root ball but no deeper.
Set each plant at the same level it was growing in the pot, then backfill and firm gently.
Space your plants using your chosen distance, then water deeply once to settle the roots.
After that, water sparingly, as lavender prefers it on the dry side.
Mulch with gravel or sand rather than bark to keep moisture away from the stems.
Prune lightly after flowering to keep the hedge bushy and prevent it from going woody.
Feed sparingly, since too much rich soil makes lavender floppy and short-lived.
So, How Close to Plant Lavender for a Hedge?
How close to plant lavender for a hedge comes down to 12 to 18 inches for a tight hedge and 18 to 24 inches for a looser one.
Match that spacing to your lavender variety, your soil, and the look you’re after.
Get the spacing right and you’ll enjoy a fragrant, low-maintenance hedge that hums with bees and looks great year after year.
Happy planting!
