How To Grow Lavender In Minnesota

Growing lavender in Minnesota is absolutely possible when you choose the right varieties and follow a few cold-climate tricks.
 
Even though Minnesota winters are brutal, lavender can survive here if you treat it like the Mediterranean plant it is.
 
You just need to understand its needs for sun, drainage, and winter protection.
 
In this post, we’ll walk through how to grow lavender in Minnesota from planting to pruning to overwintering.
 
Let’s dig in.
 

Why Growing Lavender in Minnesota Is Challenging But Doable

Growing lavender in Minnesota comes with a unique set of hurdles.
 
The main issue is that lavender hates wet feet and harsh freeze-thaw cycles.
 
Minnesota’s heavy clay soil and humid summers can be tough on lavender.
 
But with the right approach, you can absolutely grow lavender in Minnesota.
 
Here’s why it works and what you need to know.
 

1. Minnesota’s Cold Hardiness Zones

Most of Minnesota sits in USDA zones 3b to 5a.
 
That means winter temperatures can drop to -35°F in the northern parts.
 
English lavender varieties like ‘Munstead’ and ‘Hidcote’ are hardy to zone 5.
 
So if you’re in southern Minnesota, you have a fighting chance.
 
If you’re further north, you’ll need extra protection or grow lavender in containers.
 

2. The Drainage Problem

Lavender roots rot easily in soggy soil.
 
Minnesota’s clay-heavy soil holds water like a sponge.
 
So before you plant lavender in Minnesota, amend your soil with coarse sand and compost.
 
You can also plant on a raised mound or in a raised bed.
 
Good drainage is the single most important factor for growing lavender in Minnesota.
 

3. Humidity and Fungal Issues

Minnesota summers can be humid, especially in July and August.
 
Lavender is prone to root rot and fungal diseases in humid conditions.
 
So space your plants at least 18 to 24 inches apart.
 
Air circulation around the foliage keeps problems away.
 
Water at the base, not overhead, to keep leaves dry.
 

How to Plant Lavender in Minnesota

Planting lavender in Minnesota starts with timing and site selection.
 
The best time to plant is in late spring after the last frost.
 
This gives roots time to establish before winter.
 
Here’s how to do it right.
 

1. Choose the Right Variety

For growing lavender in Minnesota, stick with English lavender (Lavandula angustifolia).
 
‘Munstead’ and ‘Hidcote’ are your best bets for cold hardiness.
 
Avoid French or Spanish lavender, as they won’t survive Minnesota winters.
 
You can also try ‘Phenomenal,’ which is a hybrid with excellent winter survival.
 

2. Pick a Sunny Spot

Lavender needs at least six to eight hours of full sun daily.
 
In Minnesota, a south-facing slope or garden bed works best.
 
The more sun, the better the bloom and the stronger the scent.
 
Don’t plant lavender in Minnesota near trees or shrubs that cast shade.
 

3. Prepare the Soil

Mix coarse sand or pea gravel into your planting hole.
 
Aim for a soil pH between 6.5 and 7.5.
 
Add a handful of lime if your soil is acidic.
 
Raised beds are ideal for growing lavender in Minnesota because they drain faster.
 

Caring for Lavender in Minnesota

Once your lavender is in the ground, care is mostly about water and pruning.
 
Lavender is drought-tolerant once established.
 
Water deeply but infrequently, letting the soil dry between waterings.
 
Here are the key care steps.
 

1. Watering Wisely

Newly planted lavender needs regular water for the first few weeks.
 
After that, cut back to once a week if there’s no rain.
 
Overwatering is the number one killer of lavender in Minnesota.
 
If leaves turn yellow or roots feel mushy, you’re watering too much.
 

2. Pruning for Shape and Health

Prune lavender in early spring before new growth appears.
 
Cut back about one-third of the plant, but never into the woody stems.
 
This keeps the plant bushy and prevents it from getting leggy.
 
Light pruning after the first bloom encourages a second flush.
 

3. Fertilizing Lightly

Lavender doesn’t need much fertilizer.
 
Too much nitrogen makes it grow soft and floppy.
 
A light application of compost in spring is usually enough.
 
If your soil is poor, use a low-nitrogen fertilizer once in early spring.
 

4. Winter Protection

This is the make-or-break step for growing lavender in Minnesota.
 
After the ground freezes, mound straw or evergreen boughs around the base.
 
Don’t cover the crown too early, as that can cause rot.
 
In northern Minnesota, consider growing lavender in pots and moving them to a garage.
 

So, Can You Grow Lavender in Minnesota?

Yes, you can grow lavender in Minnesota when you choose hardy varieties and protect them from winter wet and cold.
 
The key is excellent drainage, full sun, and smart overwintering.
 
With a little patience, your Minnesota garden can enjoy lavender’s beauty and fragrance.
