How Far Apart Should You Plant Lavender Plants

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 and how you want them to look in your garden.
 
If you want a dense hedge or a full border, you can plant lavender a bit closer, around 12 inches apart.
 
If you prefer each plant to have room to breathe and grow into its natural shape, give them 18 to 24 inches of space.
 
So how far apart should you plant lavender plants?
 
The short answer is: enough space so the air moves freely between them, because lavender hates wet feet and poor airflow.
 
In this post, we’ll walk through the right spacing for different lavender varieties, why spacing matters so much, and how to get it right the first time.
 
Let’s dig in.
 

Why Spacing Lavender Plants Correctly Matters

Getting the spacing right when you plant lavender is one of the most important things you can do for their long-term health.
 
Here’s why how far apart you plant lavender makes such a difference:
 

1. Airflow Prevents Root Rot

Lavender is a Mediterranean plant that thrives in dry, sunny conditions.
 
When you plant lavender too close together, the leaves and stems stay crowded, and air can’t move between the plants.
 
That trapped moisture around the base of the plant is a recipe for root rot and fungal issues.
 
Proper spacing lets the breeze dry out the foliage after rain or watering, which keeps your lavender plants happy and healthy.
 

2. Sunlight Reaches Every Plant

Lavender needs full sun to bloom well, and when plants are packed too tightly, they start shading each other out.
 
If you plant lavender plants close together, the ones in the middle or back of the row end up leggy and weak as they stretch for light.
 
Spacing them properly means every plant gets the six to eight hours of sun it craves.
 

3. Room to Grow Without Competing

Lavender has a fairly wide root system for such a compact plant.
 
When you space lavender plants too closely, the roots fight for water and nutrients, and nobody wins.
 
Giving each plant its own little patch of soil means stronger growth and more blooms.
 

How Far Apart to Plant Lavender by Variety

Different lavender varieties grow to different sizes, so how far apart you plant lavender depends on which type you’ve got.
 
Here’s a quick breakdown:
 

1. English Lavender (Lavandula angustifolia)

English lavender is the most cold-hardy type and typically grows into a neat mound about 18 to 24 inches wide.
 
For these, plant lavender plants about 18 inches apart so they have room to spread without touching.
 
If you’re growing a hedge, 12 to 15 inches apart works fine.
 

2. French and Spanish Lavender

French and Spanish lavender varieties tend to be larger and bushier, often reaching 24 to 36 inches wide.
 
For these bigger types, you’ll want to plant lavender plants about 24 to 36 inches apart.
 
They need that extra elbow room, or they’ll sulk and produce fewer flowers.
 

3. Dwarf Lavender Varieties

Dwarf lavender stays compact, usually under 12 inches wide.
 
If you’re planting dwarf varieties, you can space lavender plants about 8 to 12 inches apart.
 
These smaller types are perfect for edging borders or growing in pots, where spacing is less of a concern.
 

Tips for Planting Lavender at the Right Distance

Now that you know how far apart to plant lavender, here are a few extra pointers to make sure it goes smoothly.
 

1. Dig the Hole Twice as Wide as the Root Ball

When you plant lavender, dig a hole that’s about twice as wide as the pot it came in.
 
This loosens the soil around the roots and gives them an easy start.
 

2. Add Grit for Drainage

Lavender loves sandy, well-draining soil.
 
If your soil is heavy clay, mix in some horticultural grit or sand before you plant lavender plants.
 

3. Don’t Amend With Rich Compost

Lavender actually prefers lean soil, so skip the rich compost.
 
Too many nutrients make lavender grow floppy and produce fewer flowers.
 

4. Water Deeply, Then Back Off

After you plant lavender, give it a good soak.
 
After that, water sparingly, because lavender is drought-tolerant once established.
 

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 up to 36 inches and dwarfs needing as little as 8 inches.
 
The key is giving each plant enough room for airflow, sunlight, and root space.
 
Get the spacing right when you plant lavender, and you’ll be rewarded with healthier plants and more of those gorgeous, fragrant blooms.
 
Happy planting.
