Lavender plants should be planted 12 to 18 inches apart for most varieties, though the exact distance depends on the type you’re growing.
If you’re wondering how far apart to plant lavender, the short answer is that spacing matters more than most gardeners realize.
Plant them too close and you’ll end up with a soggy, diseased mess.
Plant them too far apart and you waste garden space while waiting forever for them to fill in.
So getting that distance right is key to a healthy, thriving lavender patch.
In this post, we’ll break down exactly how far apart you should plant lavender, why that spacing matters, and how to adjust it based on your variety and growing conditions.
Let’s dig in.
Why Lavender Spacing Matters So Much
How far apart you plant lavender affects just about everything, from airflow to root health.
Here’s why this distance deserves your attention before you grab that trowel.
1. Airflow Prevents Disease
Lavender is a Mediterranean plant that craves dry, breezy conditions.
When you plant lavender too close together, the foliage traps moisture between plants.
That trapped humidity creates the perfect breeding ground for root rot and fungal issues like powdery mildew.
Proper spacing lets air move freely around and through your plants, keeping things dry.
2. Roots Need Room to Breathe
Lavender roots hate sitting in wet, compacted soil.
If you plant lavender plants too close, their root systems compete for space and moisture.
Overcrowded roots stay wet longer, which is basically a death sentence for lavender.
Giving each plant its own pocket of soil keeps the roots happy and healthy.
3. Sunlight Reaches Every Plant
Lavender needs full sun, at least six to eight hours a day.
When plants are crammed together, taller ones shade out the smaller ones.
That shade leads to leggy, weak growth and fewer blooms.
Correct spacing ensures every lavender plant gets its fair share of sunlight.
How Far Apart to Plant Lavender by Variety
The right distance really depends on which lavender you’re growing, since varieties vary a lot in size.
Here’s a simple breakdown to help you figure out how far apart to plant your lavender.
1. English Lavender (Lavandula Angustifolia)
English lavender is the compact, cold-hardy favorite for most gardens.
These plants typically grow 12 to 24 inches wide.
Plant English lavender about 12 to 18 inches apart.
If you’re growing a dwarf variety like ‘Hidcote’ or ‘Munstead,’ you can plant lavender as close as 12 inches apart.
2. French and Spanish Lavender
French and Spanish lavenders are larger, bushier, and less cold-hardy.
They can spread 24 to 36 inches across.
For these bigger types, plant lavender plants 18 to 24 inches apart, or even up to 30 inches in humid climates.
3. Lavandin (Lavandula x Intermedia)
Lavandins like ‘Provence’ and ‘Grosso’ are the giants of the lavender world.
These can reach 30 to 36 inches wide.
Space lavandins 24 to 36 inches apart to give them room to sprawl.
Factors That Change Your Lavender Spacing
How far apart to plant lavender isn’t a one-size-fits-all number.
A few conditions should make you adjust that distance.
1. Humidity Levels
If you live in a humid region, plant lavender farther apart than the standard recommendation.
Extra airflow is your best defense against moisture-related problems.
In damp climates, add a few inches to whatever spacing you planned.
2. Soil Drainage
Poorly draining soil means you should space lavender plants wider.
If your soil holds water, give each plant more breathing room, or amend the soil with grit and compost first.
3. Purpose of Planting
Growing lavender as a low hedge?
You can plant lavender slightly closer for a denser look, as long as airflow stays decent.
For a loose, natural cottage garden feel, space them a bit wider.
4. Container Growing
In pots, how far apart you plant lavender depends on pot size.
One lavender plant per pot is usually best, unless you’re using a very large container.
Tips for Planting Lavender at the Right Distance
Now that you know how far apart to plant lavender, here are a few quick tips to get it right.
Measure from the center of each plant, not the edges, when spacing them out.
Dig a hole twice as wide as the root ball but no deeper.
Add a layer of gravel or sand at the bottom for drainage if your soil is heavy.
Water deeply after planting, then let the soil dry out between waterings.
And resist the urge to mulch right up against the stems, since that traps moisture.
So, How Far Apart Should You Plant Lavender Plants?
Lavender plants should be planted 12 to 18 inches apart for most varieties, with larger types needing 18 to 36 inches.
Getting that spacing right keeps your lavender healthy, disease-free, and blooming beautifully.
The exact distance depends on your lavender variety, your climate, and your soil drainage.
Space them properly, and your lavender will reward you with years of fragrant, gorgeous growth.
