Should Potted Lavender Be Brought Inside For Winter

Potted lavender should be brought inside for winter in most climates, especially if you’re growing a variety that isn’t fully hardy in your growing zone.
 
Lavender loves the sun and hates soggy, frozen roots, so when winter rolls around, potted lavender can struggle outdoors in cold, wet conditions.
 
If you’ve been wondering whether potted lavender should be brought inside for winter, the short answer is yes for many gardeners, though there are exceptions depending on your climate and the type of lavender you grow.
 
In this post, we’ll look at when potted lavender should be brought inside for winter, how to do it the right way, and what happens if you leave it out in the cold.
 
Let’s dig in.
 

Why Potted Lavender Should Be Brought Inside for Winter

Lavender is a Mediterranean plant that thrives in dry, sunny, warm conditions, and that’s exactly why potted lavender should be brought inside for winter in many regions.
 
Here’s why bringing potted lavender inside for winter makes such a difference:
 

1. Potted Roots Freeze Faster Than Ground Roots

When lavender grows in the ground, the soil mass insulates the roots and protects them from freezing temperatures.
 
But potted lavender doesn’t have that luxury because the roots sit in a small volume of soil that freezes quickly, so bringing potted lavender inside for winter protects those vulnerable roots.
 

2. Wet Winter Soil Kills Lavender

Lavender hates wet feet, and cold, soggy soil is the number one killer of potted lavender in winter.
 
When potted lavender stays outside in winter rain and snow, the soil stays wet for weeks, which leads to root rot.
 
That’s another big reason potted lavender should be brought inside for winter where you can control moisture.
 

3. Cold Hardy Varieties Still Struggle in Pots

Even English lavender, which is one of the hardiest types, can suffer in a pot during a harsh winter.
 
The cold hardiness rating you see on a plant tag assumes the lavender is planted in the ground, not in a container.
 
So even if your lavender is labeled hardy to your zone, potted lavender should still be brought inside for winter to be safe.
 

When Potted Lavender Should Be Brought Inside for Winter

Timing matters when you bring potted lavender inside for winter, and getting it right keeps your plant healthy through the cold months.
 

1. Move It Before the First Hard Freeze

The best time to bring potted lavender inside for winter is right before your first hard freeze, when nighttime temps start dipping below 40°F (4°C).
 
If you wait too long, the roots may already be damaged by the cold, and bringing potted lavender inside for winter won’t undo that damage.
 

2. Bring It In Gradually

Don’t yank your lavender from a sunny patio into a dark room overnight.
 
Instead, move potted lavender inside for winter over a few days by placing it in a shaded spot first, then bringing it indoors so it can adjust.
 

3. Choose the Right Indoor Spot

When you bring potted lavender inside for winter, pick a cool, bright spot like a sunny windowsill or a heated garage.
 
Lavender needs at least six hours of light a day, so a south-facing window is ideal for potted lavender brought inside for winter.
 

How to Care for Potted Lavender Indoors in Winter

Once potted lavender is brought inside for winter, the care routine changes a bit compared to summer.
 

1. Water Sparingly

Potted lavender brought inside for winter needs far less water because growth slows down and the plant uses very little moisture.
 
Water only when the top inch of soil feels dry, and never let the pot sit in standing water.
 

2. Skip the Fertilizer

Don’t feed potted lavender that’s been brought inside for winter, since fertilizer encourages soft new growth that weakens the plant.
 
Save the feeding for spring when you move potted lavender back outside.
 

3. Keep Air Moving

Good airflow prevents mold and mildew on potted lavender brought inside for winter, so avoid cramming it against a wall.
 
A small fan on low or a cracked window on mild days helps potted lavender stay healthy indoors.
 

4. Watch for Pests

Indoor conditions can attract spider mites and whiteflies, so check potted lavender brought inside for winter every week.
 
Wiping leaves with a damp cloth keeps pests away from potted lavender growing indoors in winter.
 

When You Can Leave Potted Lavender Outside in Winter

In warm climates like zone 8 and above, potted lavender can often stay outside all winter with a little protection.
 
If you live in a mild area, potted lavender should still be brought inside for winter only during unexpected cold snaps.
 
Otherwise, you can leave potted lavender outside if you move it against a south-facing wall, wrap the pot in burlap, and elevate it on bricks so water drains freely.
 

So, Should Potted Lavender Be Brought Inside for Winter?

Potted lavender should be brought inside for winter in most climates because container roots freeze faster, wet soil causes rot, and even hardy varieties struggle in pots.
 
Bring potted lavender inside for winter before the first hard freeze, place it in a bright, cool spot, and water it sparingly.
 
If you live in a warm zone, potted lavender can stay outside with protection, but when in doubt, bringing potted lavender inside for winter is the safer choice.
 
Hope this helps you keep your potted lavender happy and healthy all winter long.
