You should plant lavender about 12 to 18 inches apart for most varieties.
If you’re growing a compact type like English lavender, that spacing works beautifully because it gives each plant just enough room to spread without crowding its neighbors.
For larger varieties, you might want to space them a bit further—around 18 to 24 inches—so they have space to reach their full size.
The key idea behind how far apart you plant lavender is simple: good airflow keeps your plants healthy and happy.
When lavender plants are too close, they compete for water, nutrients, and sunlight, and that’s when problems like root rot and fungal disease start to show up.
So how far apart do you plant lavender really depends on the variety, your climate, and how you plan to use the plants.
In this post, we’ll walk through the ideal spacing for different lavender types, why spacing matters so much, and a few extra planting tips to help your lavender thrive.
Let’s dig in.
How Far Apart Do You Plant Lavender By Variety
The right spacing for lavender isn’t one-size-fits-all because different lavender varieties grow to different sizes.
Here’s how to think about how far apart to plant lavender based on what you’re growing.
1. English Lavender (Lavandula angustifolia)
English lavender is the classic choice for gardens, and it’s a relatively compact grower.
These plants usually reach about 18 to 24 inches wide, so planting them 12 to 18 inches apart is a safe bet.
If you’re wondering how far apart to plant lavender hedges using English varieties, sticking to that 12 to 18 inch range gives you a dense, tidy look without overcrowding.
2. French and Spanish Lavender
French and Spanish lavenders are bigger, bushier plants that can spread up to 3 feet across.
For these, how far apart you plant lavender matters even more, so aim for 24 to 36 inches between each plant.
That extra space lets air move freely through the foliage, which is exactly what these heat-loving varieties need.
3. Dwarf Lavender Varieties
Dwarf lavenders stay small, often topping out at around 12 inches wide.
For these little guys, you can plant lavender about 8 to 12 inches apart and still get great results.
Just remember that even dwarf plants need breathing room, so don’t squeeze them together just because they’re small.
Why Spacing Lavender Correctly Matters
Getting the spacing right isn’t just about looks—it directly affects how healthy your lavender stays.
Here’s why how far apart you plant lavender makes such a big difference.
1. Airflow Prevents Disease
Lavender hates sitting in damp, stagnant air.
When plants are spaced properly, breezes move through the garden and dry out the foliage after rain or watering.
That airflow is your best defense against fungal issues like root rot and powdery mildew.
2. Roots Need Their Own Space
Lavender has an extensive root system that doesn’t like competing with neighbors.
When you plant lavender too close together, the roots fight for water and nutrients, and all the plants end up stressed.
Giving each plant its own patch of soil keeps the roots happy and the tops growing strong.
3. Sunlight Reaches Every Plant
Lavender is a sun worshipper and needs full sun to bloom well.
If plants are crammed together, taller ones shade out the smaller ones, and you end up with leggy, flowerless stems.
Proper spacing means every plant gets its fair share of that golden sunshine.
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 set your garden up for success.
1. Space Them Based On Mature Size
Always check the mature width of your specific variety before planting.
A good rule of thumb for how far apart you plant lavender is to use the mature width as your guide.
That way, you won’t have to dig up and move plants later when they outgrow their spot.
2. Leave Room For Airflow In Pots Too
If you’re growing lavender in containers, spacing still matters if you group pots together.
Leave a few inches between pots so air can circulate around each one.
3. Consider Your Climate
In humid climates, plant lavender a little further apart than you normally would.
Extra humidity means you need extra airflow, so err on the wider side when deciding how far apart to plant lavender.
4. Don’t Forget Drainage
Spacing and drainage go hand in hand for lavender.
Amend your soil with sand or gravel so water drains fast, and pair that with proper spacing for the healthiest plants.
So, How Far Apart Do You Plant Lavender?
You should plant lavender about 12 to 18 inches apart for most varieties.
Larger French and Spanish types need 24 to 36 inches, while dwarf varieties can sit closer at 8 to 12 inches.
The reason how far apart you plant lavender matters so much comes down to airflow, root space, and sunlight.
Get the spacing right, and your lavender will reward you with healthy growth and those gorgeous, fragrant blooms year after year.
Happy planting.
