How Close Can You Plant Lavender

You can plant lavender as close as 12 to 18 inches apart for most varieties, though the exact spacing depends on the type you’re growing.
 
If you’re wondering how close you can plant lavender, the short answer is close enough to form a lovely hedge but far enough to let air move freely between each plant.
 
That airflow is critical because lavender hates wet feet and crowded roots.
 
In this post, we’ll explore how close you can plant lavender, why spacing matters so much, and how to get it right the first time.
 
Let’s dig in.
 

How Close Can You Plant Lavender?

How close you can plant lavender really comes down to the variety and your goal.
 
Here’s the breakdown so you can plant lavender with confidence.
 

1. English Lavender: 12 to 18 Inches Apart

English lavender (Lavandula angustifolia) is the classic choice for borders and hedges.
 
You can plant English lavender about 12 to 18 inches apart if you want a tight, full look.
 
This is the closest you can plant lavender of this type without risking poor airflow.
 

2. French and Spanish Lavender: 24 to 36 Inches Apart

French and Spanish lavender grow wider and bushier than English types.
 
So how close can you plant lavender like this?
 
Give them 24 to 36 inches of space.
 
They need that extra room because their roots spread further and their foliage traps more moisture.
 

3. Dwarf Varieties: As Close As 10 to 12 Inches

If you’re growing dwarf lavender like ‘Thumbelina’ or ‘Little Lottie,’ you can plant them closer.
 
Ten to 12 inches apart works well for these compact growers.
 
This is about as close as you can plant lavender without crowding the roots.
 

Why Spacing Matters When You Plant Lavender

Planting lavender too close causes more problems than most gardeners expect.
 
Here’s why you should respect the spacing when you plant lavender.
 

1. Airflow Prevents Root Rot

Lavender is a Mediterranean plant that craves dry, breezy conditions.
 
When you plant lavender too close together, the foliage blocks wind and traps humidity.
 
That trapped moisture creates the perfect environment for root rot and fungal disease.
 

2. Sunlight Reaches Every Plant

Lavender needs full sun to bloom well.
 
If you plant lavender too tightly, taller plants shade out the smaller ones.
 
Spacing ensures every plant gets the six to eight hours of sun it needs.
 

3. Roots Have Room to Breathe

Lavender roots spread wider than you might think.
 
When you plant lavender close together, the roots compete for water and nutrients.
 
That competition weakens the plants and reduces flowering.
 

Tips for Planting Lavender at the Right Distance

Getting the spacing right is only half the battle when you plant lavender.
 
Here’s how to set your plants up for success.
 

1. Prepare the Soil First

Lavender needs sandy, well-draining soil with a pH between 6.5 and 7.5.
 
Mix in coarse sand or gravel before you plant lavender to improve drainage.
 

2. Dig Holes Slightly Wider Than the Root Ball

When you plant lavender, dig each hole about twice as wide as the pot.
 
This loosens the soil and gives roots an easy start.
 

3. Space Based on Mature Size, Not Pot Size

How close you can plant lavender depends on how big it gets, not how small it looks now.
 
Check the tag for the mature spread and space accordingly.
 

So, How Close Can You Plant Lavender?

You can plant lavender as close as 12 to 18 inches apart for English varieties, 24 to 36 inches for French and Spanish types, and 10 to 12 inches for dwarf cultivars.
 
The key is balancing the look you want with the airflow your plants need.
 
When you plant lavender at the right distance, you’ll enjoy healthier plants and bigger blooms.
