Lavender plants should be spaced about 12 to 18 inches apart for most varieties, though the exact distance depends on the type you’re growing and how you want them to look in your garden.
If you’ve been wondering how far apart to plant lavender, the short answer is that proper spacing keeps air flowing between plants, which is crucial for preventing root rot and fungal diseases.
Getting the spacing right also means your lavender will have room to spread without competing for nutrients and sunlight.
In this post, we’ll walk through how far apart to plant lavender based on variety, whether you’re growing it in beds, borders, or containers, and the common mistakes to avoid.
Let’s dig in.
How Far Apart to Plant Lavender by Variety
How far apart you plant lavender really comes down to the mature size of the variety you’ve chosen.
Here’s a breakdown to help you figure out the right spacing for your garden.
1. English Lavender (Lavandula Angustifolia)
English lavender is the classic choice for most home gardens, and it typically grows into a compact mound about 18 to 24 inches wide.
When you plant lavender of this type, space them roughly 12 to 18 inches apart.
This gives each plant enough room to fill out without smothering its neighbors.
If you’re planting a hedge or a dense border, you can push the spacing closer to 12 inches.
For a more natural, relaxed look, lean toward 18 inches.
2. Lavandin (Lavandula x Intermedia)
Lavandin varieties like ‘Grosso’ and ‘Provence’ are bigger, hardier plants that can spread up to 30 inches or more.
Because they grow larger, you’ll want to plant lavender of this type about 18 to 24 inches apart.
Crowding lavandin is one of the fastest ways to invite disease, so don’t skimp on the distance.
3. Spanish and French Lavender
Spanish and French lavender tend to be more tender and a bit more sprawling in habit.
For these types, plant lavender roughly 24 to 36 inches apart.
They appreciate the extra breathing room, especially in humid climates where airflow is everything.
4. Dwarf Lavender Varieties
Dwarf cultivars like ‘Thumbelina’ or ‘Hidcote’ stay small, often topping out around 12 inches wide.
You can plant lavender of these smaller types about 8 to 12 inches apart.
This is also a great spacing for growing lavender in tight borders or as a low edging plant.
Why Spacing Matters When You Plant Lavender
Spacing isn’t just about looks, it directly affects the health of your plants.
1. Airflow Prevents Disease
Lavender hates sitting in damp, stagnant air.
When you plant lavender too close together, moisture gets trapped between the foliage and roots.
That’s the perfect environment for root rot and fungal issues like powdery mildew.
Good spacing lets breezes move through and keeps the foliage dry.
2. Roots Need Room to Spread
Lavender has an extensive root system that needs space to grow outward.
If plants are crammed together, their roots compete for water and nutrients.
That competition stresses the plants and can stunt their growth.
3. Sunlight Reaches Every Plant
Lavender is a full-sun plant, and it needs at least six to eight hours of direct light daily.
Plant them too close and larger plants will shade smaller ones.
Proper spacing ensures every plant gets its share of the sun.
Tips for Spacing Lavender in Different Settings
The ideal distance can shift a little depending on where you’re growing your lavender.
1. In Garden Beds and Borders
For garden beds, stick with the variety-based spacing above.
A good rule of thumb is to plant lavender so that at maturity, the plants just barely touch.
This creates a full look without overcrowding.
2. In Containers
When growing lavender in pots, plant just one per container.
Lavender doesn’t like competition, and a single plant in a pot will thrive far better than two squeezed together.
Choose a pot at least 12 inches wide so the roots have room to expand.
3. In Hedges and Mass Plantings
For a lavender hedge, space plants about 12 inches apart for a tight, formal look.
If you want a looser, more natural mass planting, go with 18 to 24 inches.
Just remember, tighter spacing means you’ll need to prune more diligently to maintain airflow.
4. Consider Climate and Humidity
If you live in a humid region, err on the side of wider spacing.
Extra distance between plants helps combat the moisture that humid air brings.
In drier climates, you have a little more flexibility to plant lavender closer together.
So, How Far Apart Do You Plant Lavender?
You plant lavender about 12 to 18 inches apart for most varieties, with larger types needing 18 to 24 inches and smaller dwarfs doing fine at 8 to 12 inches.
The key is matching your spacing to the mature size of your plants and the climate you’re growing in.
Give your lavender room to breathe, and it’ll reward you with healthier growth and those gorgeous, fragrant blooms year after year.
Happy planting.
