Does Lavender Need To Be Covered In Winter

Lavender needs to be covered in winter only in certain conditions.

 

If you’ve been asking yourself does lavender need to be covered in winter, the short answer is: it depends on your climate, your lavender variety, and how you’ve planted it.

 

In mild climates, lavender usually sails through winter without any protection at all.

 

But in colder zones with freezing temperatures, harsh winds, and heavy snow, covering lavender in winter can mean the difference between a thriving plant and a dead one come spring.

 

In this post, we’ll go over when you should cover lavender in winter, when you shouldn’t, and the best ways to protect lavender plants so they survive the cold season.

 

Let’s dig in.

 

Does Lavender Need to Be Covered in Winter?

 

Lavender needs to be covered in winter when you live in a cold climate or grow a tender variety that can’t handle freezing temps.

 

English lavender, for example, is one of the hardiest types and can survive winters down to about zone 5.

 

French and Spanish lavender, on the other hand, are much more tender and will need winter protection in anything below zone 7 or 8.

 

Keeping lavender alive through winter really comes down to a few key things:

 

1. Your Climate Zone

 

The biggest factor in whether you need to cover lavender in winter is where you live.

 

If you’re in USDA zones 5 to 7, most hardy lavender varieties will survive without cover, though a little mulch around the base helps.

 

In zones 4 and below, covering lavender in winter isn’t just a good idea, it’s pretty much essential.

 

And if you’re in zone 8 or warmer, covering lavender is usually unnecessary and can even cause more harm than good.

 

2. The Lavender Variety You Grow

 

Not all lavender is built the same when it comes to cold tolerance.

 

English lavender varieties like ‘Munstead’ and ‘Hidcote’ are the toughest and rarely need winter cover in moderate climates.

 

Lavandins are also quite hardy and can handle cold snaps well.

 

But if you’re growing French lavender or Spanish lavender, you’ll definitely want to cover them in winter or grow them in pots you can move indoors.

 

3. Whether It’s Planted in the Ground or a Pot

 

Lavender planted in the ground has the earth as insulation, which helps protect the roots from freezing.

 

Lavender in pots doesn’t have that luxury, so the roots are much more exposed to cold.

 

If your lavender is in a container, covering it in winter or moving it to a sheltered spot is basically a must in cold regions.

 

When You Should Cover Lavender in Winter

 

You should cover lavender in winter when temperatures regularly drop below 20°F (-6°C) and stay there.

 

You should also cover lavender if you’re growing tender varieties, if your plants are young, or if they’re in pots exposed to wind and frost.

 

Here are a few situations where covering will save your lavender:

 

1. You Live in Zone 5 or Colder

 

In these zones, winter can be brutal.

 

Covering lavender in winter helps insulate the crown and roots from hard freezes.

 

You don’t need to smother the plant, just give it a protective layer of mulch, straw, or a breathable cover.

 

2. You Grow Tender Lavender Varieties

 

French and Spanish lavender aren’t fans of the cold.

 

Covering these in winter, especially during freezing nights, gives them a fighting chance to come back strong in spring.

 

3. Your Lavender Is in a Pot

 

Container lavender is very vulnerable in winter.

 

Covering the pot or wrapping it with burlap can protect the roots from freezing solid.

 

You can also move pots to a sheltered wall or garage if you have the space.

 

How to Cover Lavender in Winter the Right Way

 

Covering lavender in winter isn’t complicated, but doing it wrong can do more harm than good.

 

Here’s how to protect lavender plants properly:

 

1. Don’t Cover the Crown Too Early

 

Wait until the ground is about to freeze before you add cover.

 

Covering too early traps warmth and moisture, which can lead to rot.

 

2. Use Breathable Materials

 

Straw, pine needles, or horticultural fleece work great.

 

Avoid plastic or anything that seals in moisture, because that’s a recipe for fungal problems.

 

3. Keep Cover Loose Around the Plant

 

Don’t pile mulch right up against the stems.

 

Leave a little breathing room around the crown so air can circulate.

 

4. Remove Cover in Early Spring

 

As soon as the worst of the cold passes, uncover your lavender.

 

Leaving cover on too long can trap heat and cause the plant to rot.

 

So, Does Lavender Need to Be Covered in Winter?

 

Lavender needs to be covered in winter only if you live in a cold climate, grow a tender variety, or have lavender in pots.

 

In milder zones and with hardy English lavender, covering lavender in winter often isn’t necessary at all.

 

The key is knowing your zone and your plant so you can decide if covering lavender in winter is the right move for your garden.

 

Do that, and your lavender will reward you with fragrant blooms year after year.
