When To Bring Lavender Inside

You should bring lavender inside before the first hard frost hits, especially if you’re growing a tender variety that won’t survive freezing temperatures.
 
Knowing when to bring lavender inside can mean the difference between a plant that thrives for years and one that turns to brown mush overnight.
 
If you’ve been asking yourself when to bring lavender inside, the short answer is simple: timing depends on your climate, your lavender type, and how cold it’s getting at night.
 
In this post, we’ll walk through exactly when to bring lavender inside, how to do it without shocking the plant, and how to keep it happy all winter long.
 
Let’s dig in.
 

When to Bring Lavender Inside

When to bring lavender inside really comes down to watching the thermometer, not the calendar.
 
Most lavender varieties start to suffer once nighttime temperatures dip below 40°F (4°C).
 
Hardy English lavenders can handle a light frost, but tender Spanish and French lavenders will not.
 
So the ideal window for when to bring lavender inside is right before that first frost warning.
 
If you wait too long, the roots can freeze and the plant may never recover.
 

1. Check Your Lavender Variety First

Not all lavender is created equal, and this matters a lot when deciding when to bring lavender inside.
 
English lavender (Lavandula angustifolia) is the hardiest and can survive down to about 10°F in the ground.
 
French and Spanish lavenders, on the other hand, are tender and need protection once temps drop below 50°F at night.
 
If you’re growing lavender in a pot, the roots are far more exposed to cold than they would be in the ground.
 
That means potted lavender should come inside even earlier, often when nights hit the mid-40s.
 

2. Watch the Weather Forecast Closely

The best way to nail when to bring lavender inside is to keep an eye on your local forecast.
 
Once you see nighttime lows creeping toward 40°F, it’s time to start planning.
 
Don’t wait for the actual frost, because by then the damage may already be done.
 
A good rule of thumb: bring lavender inside a week or two before your area’s average first frost date.
 
This gives the plant time to adjust to indoor conditions gradually.
 

3. Signs Your Lavender Is Ready to Come In

Your plant will often tell you when to bring lavender inside if you pay attention.
 
Look for slowed growth, yellowing lower leaves, or a general look of “stalling out.”
 
You might also notice the soil staying wet longer, which happens when the plant slows down in cool weather.
 
These are all cues that your lavender is preparing for dormancy and would rather be indoors.
 

How to Bring Lavender Inside Without Stressing It

Once you’ve figured out when to bring lavender inside, the next step is doing it gently.
 
Lavender doesn’t love abrupt changes, so a little preparation goes a long way.
 

1. Transition It Gradually

If you can, move your lavender to a shaded, sheltered spot outdoors for a few days first.
 
This helps it acclimate to lower light levels before coming all the way inside.
 
Then bring it in and place it near a bright window.
 

2. Pick the Right Indoor Spot

Lavender needs at least six hours of sunlight a day, even indoors.
 
A south-facing window is usually your best bet.
 
If natural light is scarce, a grow light can fill the gap.
 

3. Ease Up on Watering

When you bring lavender inside, cut back on watering significantly.
 
Indoor air is drier and the plant’s growth slows, so it needs much less moisture.
 
Let the top inch of soil dry out completely between waterings to avoid root rot.
 

Common Mistakes to Avoid When Bringing Lavender Inside

Even when you know when to bring lavender inside, a few missteps can sabotage your plant.
 
Here are the biggest ones to watch for.
 

1. Bringing It In Too Late

Waiting until after a frost is the number one mistake people make with lavender.
 
Once the roots freeze, the damage is usually irreversible.
 
So set a reminder and act before that first cold snap.
 

2. Overwatering Indoors

Lavender hates soggy roots, and indoor conditions make overwatering even easier to do.
 
Always err on the side of underwatering during the winter months.
 

3. Skipping Good Airflow

Stuffy rooms encourage mildew and fungal issues on lavender.
 
Keep a little air moving around the plant, but avoid cold drafts from doors and windows.
 

4. Forgetting to Check for Pests

Before you bring lavender inside, inspect the leaves and soil for aphids, spider mites, or whiteflies.
 
A quick rinse or a dab of insecticidal soap can stop an infestation before it spreads to your other houseplants.
 

So, When Should You Bring Lavender Inside?

You should bring lavender inside before the first hard frost, ideally when nighttime temperatures start dipping toward 40°F.
 
Knowing when to bring lavender inside protects your plant from cold damage and gives it a chance to rest comfortably through winter.
 
Tender varieties like French and Spanish lavender need to come in even earlier than hardy English types, and potted lavender is always more vulnerable than plants in the ground.
 
Watch your forecast, transition the plant gradually, and dial back the watering once it’s indoors.
 
Do that, and your lavender will reward you with healthy growth and fragrant blooms when the warmer months roll back around.
