You can bring lavender in for the winter, and it’s absolutely worth doing if you want to keep those fragrant plants thriving year after year.
Bringing lavender indoors isn’t just possible, it’s actually a smart way to protect your plants from harsh frosts and freezing temperatures that can kill them outright.
The key is understanding that lavender isn’t a typical houseplant, so you’ll need to mimic its natural Mediterranean conditions to help it survive the colder months successfully.
In this post, we’ll explore exactly how you can bring lavender in for the winter, the steps to prepare your plants, and the common mistakes to avoid so your lavender comes back stronger in spring.
Let’s dig in and get your lavender ready for its indoor season.
Why You Should Bring Lavender In For The Winter
The main reason you bring lavender in for the winter is to shield it from extreme cold and wet soil that can cause root rot and plant death.
Lavender is hardy in many zones, but container-grown plants are especially vulnerable because their roots are exposed to colder temperatures than those planted in the ground.
When you bring lavender in for the winter, you also protect it from harsh winds, heavy snow, and the freeze-thaw cycles that can damage stems and buds.
If your region experiences temperatures below 10°F (-12°C) or prolonged freezing, bringing lavender indoors gives it a much better chance of survival.
Even in milder climates, moving your potted lavender to a sheltered spot or indoors can prevent waterlogged soil from killing the roots during winter rains.
1. Container Lavender Needs Extra Protection
Potted lavender is far more exposed than garden lavender, so you should bring lavender in for the winter if it’s growing in a container.
The soil in pots freezes much faster and harder than ground soil, which can damage or kill the root system entirely.
When you bring lavender in for the winter, you give those roots a stable temperature that doesn’t fluctuate dangerously.
Container lavender also dries out faster in winter winds, but indoor conditions allow you to control moisture levels more precisely.
2. Cold-Hardy Varieties Still Benefit From Indoors
Even if you have a cold-hardy variety like English lavender, you might still choose to bring lavender in for the winter if it’s young or newly planted.
Young lavender plants haven’t developed the deep root systems needed to survive harsh winters, so indoor protection makes a big difference.
You can also bring lavender in for the winter to extend the growing season and enjoy fresh leaves or flowers for culinary or aromatic uses.
Many gardeners bring lavender indoors simply because they want to preserve their favorite variety that might not be fully hardy in their zone.
How To Bring Lavender In For The Winter Successfully
To bring lavender in for the winter without shocking the plant, you need to follow a few important steps that start weeks before the first frost.
Lavender doesn’t like sudden changes, so gradual acclimation is key to helping it adjust to indoor conditions without dropping leaves or stressing out.
Here’s how to make the transition smooth and give your lavender the best chance of winter survival indoors.
1. Time Your Move Before The First Hard Frost
Check your local frost dates and bring lavender in for the winter before temperatures dip below freezing for more than a few hours.
Ideally, move your lavender indoors when nighttime temperatures start hovering around 40°F (4°C) to avoid any cold damage.
Don’t wait until the plant looks stressed or frostbitten, as that weakens its chances of recovering indoors.
A good rule is to bring lavender in for the winter about two weeks before your average first frost date to be safe.
2. Inspect And Treat For Pests First
Before you bring lavender in for the winter, thoroughly check the plant for aphids, spider mites, or other hidden pests that could infest your home.
Spray the foliage with a gentle stream of water to knock off any insects, and consider applying an insecticidal soap as a preventive treatment.
Also remove any dead leaves or flowers that might harbor fungal spores or attract bugs while indoors.
This step is crucial because once you bring lavender in for the winter, pests can multiply quickly in warm indoor air.
3. Repot If Needed And Refresh The Soil
If your lavender is root-bound or the soil has become compacted, repot it into a slightly larger container with fresh, well-draining potting mix.
Lavender hates wet feet, so ensure your pot has excellent drainage holes and use a gritty mix that includes sand or perlite.
When you bring lavender in for the winter, fresh soil gives the roots room to breathe and reduces the risk of rot from overwatering indoors.
Avoid using heavy garden soil that retains too much moisture, as this is a leading cause of indoor lavender death.
4. Choose The Brightest Spot In Your Home
Lavender is a sun-loving plant, so when you bring lavender in for the winter, place it in a south-facing window that gets at least 6 to 8 hours of direct sunlight daily.
If you don’t have enough natural light, supplement with a grow light placed just a few inches above the plant for about 12 hours a day.
Without adequate light, lavender will become leggy, pale, and weak, so this is one of the most important factors for indoor success.
A sunny windowsill in a cool room is often the ideal spot for lavender during winter dormancy.
5. Adjust Watering And Temperature For Dormancy
Lavender goes semi-dormant in winter, so when you bring lavender in for the winter, reduce watering significantly and let the soil dry out between waterings.
Overwatering is the number one killer of indoor lavender, so only water when the top inch of soil feels completely dry to the touch.
Keep temperatures on the cooler side, ideally between 50°F and 60°F (10°C to 15°C), to mimic its natural winter rest period.
Avoid placing lavender near heat vents, radiators, or fireplaces, as hot dry air will stress the plant and cause leaf drop.
Common Mistakes When You Bring Lavender In For The Winter
Many gardeners make errors that harm or kill lavender after bringing it inside, so it’s helpful to know what to avoid.
The biggest mistake is treating indoor lavender like a tropical houseplant that needs constant warmth and moisture.
Another common error is moving lavender abruptly from outside to indoors without acclimating it, which causes shock and leaf yellowing.
People also forget that lavender needs air circulation indoors, so placing it in a stagnant corner can lead to mold or mildew issues.
Finally, don’t fertilize lavender during winter, as this encourages soft growth that’s vulnerable to pests and diseases.
1. Don’t Overwater Indoor Lavender
When you bring lavender in for the winter, it’s easy to overwater out of habit, but lavender prefers dry soil and low humidity.
Let the soil dry out thoroughly between waterings, and always check moisture with your finger before adding more water.
If the pot feels heavy or the soil looks dark and damp, skip watering for another few days.
Remember, lavender roots that sit in soggy soil will rot quickly and kill the plant within weeks.
2. Don’t Expect Continuous Growth Or Flowers
Lavender naturally slows down in winter, so don’t panic if it looks slightly dormant or stops producing new growth after you bring lavender in for the winter.
This rest period is essential for the plant to conserve energy and bloom beautifully the following summer.
Avoid pruning heavily in winter, as lavender stores energy in its woody stems and cutting too much can weaken it.
Just keep it alive and healthy through winter, and you’ll be rewarded with vigorous growth and fragrant flowers come spring.
So, Can You Bring Lavender In For The Winter?
Yes, you can bring lavender in for the winter, and it’s a practical way to protect your plants from freezing temperatures and harsh conditions.
By following the right steps, including gradual acclimation, proper light, careful watering, and cool temperatures, your lavender can thrive indoors through the coldest months.
The key is to treat lavender as a Mediterranean plant that prefers bright light, dry soil, and cooler air rather than a typical tropical houseplant.
So whether you’re saving a favorite variety or starting new plants for next spring, you can absolutely bring lavender in for the winter successfully.
Just remember to check for pests, choose a sunny window, water sparingly, and let your lavender rest until warmer days return.
Your patience and care will pay off when your lavender bursts back to life with those lovely purple blooms and calming fragrance next season.
Happy gardening, and enjoy your indoor lavender all winter long!
