You can grow lavender in Maine successfully, even though the state is known for its cold winters and short growing season.
The key is choosing the right varieties, planting them in the right spot, and giving them the specific care they need to survive Maine’s climate.
If you’ve been wondering how to grow lavender in Maine, you’re in the right place because it’s absolutely doable with a little planning.
In this post, we’ll cover the best lavender varieties for Maine, how to plant and care for them, and how to overwinter them so they come back year after year.
Let’s dig in.
Why You Can Grow Lavender in Maine
Growing lavender in Maine works because lavender is a hardy perennial when you pick the right type.
The state’s cool summers and well-drained soils in many areas actually suit lavender better than you might think.
The main challenge is winter wet and cold, not the summer heat.
If you can manage moisture and choose cold-hardy varieties, growing lavender in Maine becomes a rewarding project.
Here’s why it works:
1. Cold-Hardy Varieties Exist
English lavender varieties like ‘Munstead’ and ‘Hidcote’ are your best bet for growing lavender in Maine.
These are rated for USDA zones 5–8, and most of Maine sits in zones 4–5, so they can handle the cold.
‘Munstead’ is especially tough and has been grown successfully in Maine gardens for years.
Avoid French and Spanish lavender, which are tender and won’t survive a Maine winter.
2. Maine’s Soil Can Be Amended
Lavender hates wet feet, and Maine’s native soil tends to be acidic and heavy in many spots.
But you can fix that by mixing in sand, gravel, or compost to improve drainage.
Raised beds are a fantastic option for growing lavender in Maine because they keep roots out of soggy ground.
A pH between 6.5 and 7.5 is ideal, so add lime if your soil is too acidic.
3. The Growing Season Is Short but Sufficient
Maine’s growing season runs from late May to early October, which gives lavender enough time to bloom.
Lavender typically flowers from June to August, right in the middle of that window.
As long as you start with healthy plants, growing lavender in Maine will give you plenty of blooms.
Just don’t expect a long harvest like you’d get in Provence.
How to Plant Lavender in Maine
Planting lavender in Maine the right way sets you up for success from day one.
Follow these steps to give your plants the best start:
1. Wait Until After the Last Frost
In Maine, the last frost can happen as late as mid-to-late May, depending on your region.
Plant lavender outdoors only after the soil has warmed and the danger of frost has passed.
If you’re in northern Maine, you might wait until early June.
This timing is crucial for growing lavender in Maine because cold soil shocks young plants.
2. Choose a Sunny Spot
Lavender needs at least six to eight hours of full sun every day.
Pick the sunniest spot in your yard, ideally on a south-facing slope.
Good air circulation also helps prevent fungal issues, which lavender is prone to in humid climates.
Don’t plant lavender in a low spot where water pools after rain.
3. Amend the Soil for Drainage
Mix your soil with coarse sand or small gravel to improve drainage before planting.
If you’re using a raised bed, fill it with a mix of potting soil, sand, and compost.
Add a handful of lime to sweeten acidic soil, since lavender prefers slightly alkaline conditions.
Good drainage is the single most important factor when growing lavender in Maine.
4. Space Plants Properly
Space lavender plants about 18 to 24 inches apart to allow for airflow.
Crowding leads to poor circulation and invites disease, especially in Maine’s humid summers.
Dig a hole twice as wide as the root ball but no deeper.
Set the plant so the crown sits slightly above soil level to keep water from pooling around the stem.
Caring for Lavender in Maine
Once your lavender is in the ground, the care routine is simple but specific.
Here’s what you need to do:
1. Water Sparingly
Lavender is drought-tolerant once established and hates being overwatered.
Water deeply but infrequently, letting the soil dry out between waterings.
In Maine’s rainy stretches, make sure your soil drains fast and never stays soggy.
Overwatering is the number one killer of lavender in Maine.
2. Prune Regularly
Prune lavender lightly in early spring to remove dead growth and shape the plant.
After blooming, trim back about a third of the plant to encourage bushy growth.
Never cut into the woody base, as it may not regrow.
Regular pruning keeps your lavender healthy and helps it survive Maine winters.
3. Fertilize Lightly
Lavender doesn’t need much fertilizer and too much can harm it.
A light application of compost in spring is usually enough.
Avoid high-nitrogen fertilizers, which cause leafy growth at the expense of flowers.
Growing lavender in Maine is more about good soil and drainage than feeding.
4. Overwinter with Care
Winter is the hardest part of growing lavender in Maine.
Protect plants by mulching around them with straw or evergreen boughs after the ground freezes.
Don’t mulch too early, as it can trap moisture and cause rot.
In colder zones, you can also grow lavender in pots and move them to a sheltered spot or unheated garage for winter.
So, How Do You Grow Lavender in Maine?
You grow lavender in Maine by choosing cold-hardy English varieties, planting them in well-drained soil, and protecting them through winter.
It takes a bit of effort, but the reward is a fragrant, beautiful plant that comes back year after year.
With the right variety, good drainage, and proper winter care, growing lavender in Maine is absolutely achievable.
Give it a try this season and enjoy the sweet smell of success in your own garden.
