How Far Apart Should Lavender Plants Be Planted

Lavender plants should be planted about 12 to 18 inches apart for most varieties, though the exact spacing depends on the type you’re growing.
 
If you’re wondering how far apart lavender plants should be, the short answer is: give them enough room to breathe.
 
Spacing lavender properly is one of the most important things you can do to keep your plants healthy and thriving.
 
In this post, we’ll break down exactly how far apart to plant lavender, why spacing matters so much, and how to get it right the first time.
 
Let’s dig in.
 

How Far Apart Should Lavender Plants Be Planted?

How far apart lavender plants should be planted really comes down to the variety and the purpose of your planting.
 
As a general rule, space lavender plants 12 to 18 inches apart in the garden.
 
That said, here’s a closer look at the numbers based on what you’re growing.
 

1. English Lavender (Lavandula Angustifolia)

English lavender is the classic hardy type most gardeners grow.
 
For these, plant lavender about 12 to 18 inches apart.
 
They stay relatively compact, so this spacing gives them room without wasting garden space.
 

2. French and Spanish Lavender

French and Spanish lavender tend to grow wider and looser.
 
For these larger types, how far apart you plant lavender should be closer to 24 to 36 inches.
 
They need that extra room because their sprawling habit can crowd neighboring plants fast.
 

3. Dwarf Lavender Varieties

Dwarf varieties stay small and tidy.
 
You can plant lavender plants about 8 to 12 inches apart with these.
 
Just don’t go tighter than that, even if they look tiny at planting time.
 

4. Lavender in Hedges or Borders

If you’re planting a lavender hedge, space plants 12 to 15 inches apart.
 
This lets them grow into a continuous line while still giving each plant airflow.
 
For a looser border, plant lavender closer to 18 inches apart.
 

Why Lavender Spacing Matters So Much

Getting lavender spacing right isn’t just about looks.
 
It affects the health of your plants in a big way.
 

1. Airflow Prevents Root Rot

Lavender hates wet feet.
 
When plants are too close, air can’t move between them, and the soil stays damp longer.
 
That’s a recipe for root rot, which is the number one killer of lavender.
 

2. Sunlight Reaches Every Plant

Lavender needs full sun to bloom well.
 
If you plant lavender plants too close together, the larger ones shade the smaller ones.
 
Proper spacing means every plant gets the six to eight hours of sun it craves.
 

3. Fewer Pests and Diseases

Crowded lavender is a magnet for fungal issues and pests.
 
Good airflow from correct spacing keeps the foliage dry and less inviting to problems.
 

4. Room to Grow Without Competition

Roots need space too.
 
When you plant lavender too close, the roots compete for water and nutrients.
 
Spacing them properly lets each plant establish a strong, independent root system.
 

Tips for Planting Lavender at the Right Distance

Now that you know how far apart lavender plants should be, here’s how to get it right.
 

1. Measure Before You Dig

It sounds obvious, but most people guess.
 
Use a tape measure and mark your spots before planting.
 
This ensures your lavender spacing is consistent across the bed.
 

2. Account for Mature Size

Don’t space based on how small the plants look now.
 
Check the mature spread of your variety and plant lavender accordingly.
 
A plant that looks tiny today can double in width within a season or two.
 

3. Plant in Raised Beds or Mounds

If your soil drains poorly, plant lavender in raised beds or on small mounds.
 
This improves drainage and lets you control how far apart lavender plants sit.
 
It’s a simple fix that makes a huge difference.
 

4. Leave Room for Airflow Between Rows

If you’re planting multiple rows, space the rows 24 to 36 inches apart.
 
This keeps air moving through the whole patch, not just between individual plants.
 

So, How Far Apart Should Lavender Plants Be Planted?

Lavender plants should be planted 12 to 18 inches apart for most varieties, with larger types needing up to 36 inches.
 
The exact distance depends on the variety, but the goal is always the same: give each plant room to breathe.
 
Proper lavender spacing means better airflow, more sun, healthier roots, and fewer problems down the road.
 
Get the spacing right at planting time and your lavender will reward you for years with fragrant blooms and sturdy growth.
