You can plant lavender outside by choosing a sunny spot with well-draining soil and planting it in the spring or early fall.
Planting lavender outside is actually easier than most people think, as long as you give it the conditions it craves.
If you’ve been wondering how do you plant lavender outside, the answer mostly comes down to sun, drainage, and spacing.
Lavender hates wet feet, loves the heat, and thrives when you plant it outside in a spot that gets at least six to eight hours of direct sunlight.
In this post, we’ll walk through exactly how to plant lavender outside, from picking the right location to caring for it after it’s in the ground.
How Do You Plant Lavender Outside Step by Step
Planting lavender outside starts with picking the right location, then preparing the soil, then getting the plant in the ground the right way.
Here’s how to do each part so your lavender settles in happily.
1. Choose a Spot With Full Sun
Lavender needs full sun to bloom well and stay healthy.
Pick a spot that gets at least six to eight hours of direct sunlight every day.
The more sun the better, especially in cooler climates.
If you plant lavender outside in a shady spot, it’ll get leggy, produce fewer flowers, and become more prone to disease.
2. Make Sure the Soil Drains Well
Drainage is the number one thing lavender cares about.
Lavender roots rot quickly in soggy soil, so you want a spot where water never pools.
If your soil is heavy clay, amend it with coarse sand or gravel before you plant lavender outside.
You can also plant lavender outside on a slight slope or in a raised bed to help water drain away.
Aim for slightly alkaline soil with a pH between 6.7 and 7.3.
3. Dig a Hole Wider Than the Root Ball
When you’re ready to plant lavender outside, dig a hole about twice as wide as the nursery pot and just as deep.
Width matters more than depth because lavender roots spread outward.
Loosen the soil around the hole so roots can move freely.
If you’re planting lavender outside in a container, make sure it has drainage holes and fill it with a gritty, well-draining mix.
4. Plant at the Right Depth
Set the lavender in the hole so the top of the root ball sits level with the surrounding soil.
Don’t bury the crown, which is where the stems meet the roots, or the plant could rot.
Backfill gently, firm the soil with your hands, and water lightly.
When you plant lavender outside, the crown should stay slightly above the soil line to keep moisture away.
5. Space Plants Properly
Give lavender room to breathe.
Space English lavender about 18 to 24 inches apart, and larger varieties up to 3 feet apart.
Good air circulation prevents fungal issues and helps the plant grow evenly.
If you plant lavender outside too close together, they’ll compete for nutrients, sunlight, and airflow.
When Is the Best Time to Plant Lavender Outside
The best time to plant lavender outside is in spring after the last frost, or in early fall in warmer climates.
Spring planting gives lavender a full season to establish roots before winter.
Fall planting works well in mild regions where winters don’t get too harsh.
Avoid planting lavender outside during the peak of summer heat, as the stress can stunt new growth.
Also skip planting in frozen or waterlogged ground, since roots won’t settle properly.
Caring for Lavender After You Plant It Outside
Once you plant lavender outside, a little aftercare goes a long way.
Water newly planted lavender deeply once or twice a week for the first month, then cut back.
After that, lavender is drought-tolerant and usually only needs water during long dry spells.
Don’t overwater, as that’s the fastest way to kill lavender.
Add a light layer of gravel or sand mulch around the base to keep moisture off the crown.
Prune lightly after the first bloom to keep the plant bushy and prevent it from going woody.
If you live in a cold climate, add a layer of mulch in late fall to protect the roots through winter.
So, How Do You Plant Lavender Outside?
You plant lavender outside by choosing a sunny spot with well-draining soil, digging a wide hole, and setting the plant so the crown sits at or slightly above soil level.
Plant lavender outside in spring or early fall, space plants 18 to 36 inches apart, and water deeply until roots establish.
Give it full sun, avoid soggy soil, and prune lightly after blooming.
Do all that, and your lavender will reward you with fragrant blooms for years.
