How To Grow A Lavender Hedge

Growing a lavender hedge is one of the most rewarding things you can do for your garden if you love that calming scent and those gorgeous purple blooms.
 
It’s not just about planting a few stems and hoping for the best though.
 
To grow a lavender hedge properly, you need to pick the right variety, prepare the soil, plant at the right time, and prune like you mean it.
 
The good news is that once you know how to grow a lavender hedge, it becomes a low-maintenance superstar that bees adore and neighbors envy.
 
In this post, we’ll walk through exactly how to grow a lavender hedge from scratch so you can enjoy a fragrant, tidy border for years.
 

How to Grow a Lavender Hedge Successfully

Learning how to grow a lavender hedge starts with understanding what lavender actually needs.
 
These plants hate wet feet, love the sun, and need good air circulation.
 
If you get those three things right, growing a lavender hedge becomes almost effortless.
 
Here are the key steps to getting it right from day one.
 

1. Choose the Right Lavender Variety for Hedging

Not all lavender is created equal when it comes to hedging.
 
English lavender (Lavandula angustifolia) is the best choice for a compact, uniform hedge because it’s hardy and blooms early.
 
Varieties like ‘Hidcote’ and ‘Munstead’ are ideal for growing a lavender hedge since they stay neat and bushy.
 
French and Spanish lavenders are lovely but they’re less hardy and tend to sprawl, which makes them a poor fit for a formal hedge.
 
If you want a lavender hedge that survives winter and looks sharp, stick with English types.
 

2. Plant in Full Sun and Well-Drained Soil

Lavender needs at least six to eight hours of direct sun every day.
 
If your spot is shady, growing a lavender hedge will be an uphill battle.
 
The soil matters just as much.
 
Lavender roots rot in heavy, soggy clay, so you need well-drained soil.
 
If your garden soil is heavy, mix in plenty of grit, horticultural sand, or compost to improve drainage.
 
You can also plant your lavender hedge on a slight mound or raised bed to keep water moving away from the roots.
 
Aim for a soil pH between 6.5 and 7.5, which is slightly alkaline to neutral.
 

3. Space Plants Correctly for a Dense Hedge

Spacing is where a lot of people go wrong when they grow a lavender hedge.
 
Plant them too far apart and you’ll get gaps; too close and they’ll compete and sulk.
 
For most English lavender varieties, space plants about 12 to 18 inches apart.
 
That gives them room to spread while still knitting together into a continuous hedge.
 
If you’re growing a lavender hedge along a path, measure the length of the border and divide by your spacing to figure out how many plants you need.
 
Dig a hole slightly wider than the root ball, place the plant at the same depth it was in its pot, and firm the soil gently.
 
Water them in well after planting to settle the roots.
 

4. Water Wisely While the Hedge Establishes

Newly planted lavender needs regular watering for the first few weeks.
 
But once your lavender hedge is established, it’s drought-tolerant and prefers to dry out between waterings.
 
Overwatering is the number one killer of lavender hedges.
 
So water deeply but infrequently, and never let the plants sit in soggy soil.
 
In hot, dry climates, a deep soak every week or two during summer is plenty.
 
In cooler or wetter areas, you might barely need to water at all once they’re settled in.
 

Pruning and Caring for Your Lavender Hedge

If there’s one secret to a long-lasting lavender hedge, it’s pruning.
 
Skip it and your plants turn woody, leggy, and ugly within a couple of years.
 
Here’s how to keep your lavender hedge looking full and healthy.
 

1. Prune After Flowering, Not Before

The best time to prune a lavender hedge is right after the first flush of flowers fades.
 
For English lavender, that’s usually late summer.
 
Cut back the flower stems and about one-third of the leafy growth, but never cut into the old woody stems.
 
Those woody parts won’t regrow, so if you cut too hard, you’ll leave permanent gaps in your hedge.
 
A light trim in early spring is also fine to tidy up winter damage, but keep it gentle.
 

2. Don’t Cut Into Old Wood

This is the golden rule of growing a lavender hedge.
 
Always leave at least two or three inches of green growth below your cut.
 
Lavender doesn’t regenerate from old wood, so pruning into the brown stems will kill that branch.
 
If your hedge is already leggy, you can rejuvenate it slowly over two or three seasons by cutting back a little more each year.
 
But patience is key here, and you can’t rush a lavender hedge back into shape.
 

3. Feed Lightly and Avoid Rich Soil

Lavender isn’t a hungry plant.
 
Too much fertilizer, especially nitrogen, makes it grow soft and floppy with fewer flowers.
 
A light sprinkle of compost or a low-nitrogen fertilizer in spring is all your lavender hedge needs.
 
If your soil is already decent, you might not need to feed at all.
 
Just focus on drainage and sun, and your hedge will thank you with abundant blooms.
 

So, How Do You Grow a Lavender Hedge?

You grow a lavender hedge by choosing English lavender, planting it in full sun with well-drained soil, spacing plants 12 to 18 inches apart, watering sparingly once established, and pruning every year after flowering.
 
It’s really that simple once you know what lavender wants.
 
Get the basics right and your lavender hedge will reward you with years of fragrance, color, and happy bees.
 
So pick your spot, grab your plants, and start growing a lavender hedge you’ll love.
