Why Grow Lavender Indoors?
Bringing lavender indoors offers a unique blend of aesthetic appeal, delightful fragrance, and potential well-being benefits. Imagine snipping fresh lavender sprigs for a calming tea or a homemade sachet, all from your windowsill. It’s like bringing a piece of the sunny Mediterranean into your living space, even without a sprawling garden.
Indoor lavender plants can brighten up any corner, adding a touch of natural elegance. Their lovely purple blooms and distinctive scent can reduce stress and create a more peaceful atmosphere. Plus, for those with limited outdoor space, like apartment dwellers or those in colder climates, growing lavender indoors is a fantastic way to enjoy this beloved herb.
Choosing the Right Lavender for Indoors
Not all lavenders are created equal when it comes to indoor growing. Some varieties are much better suited to container life and a more controlled environment. The key is to look for compact varieties that don’t require extensive pruning or a huge root system.
Top Lavender Varieties for Indoor Success
- Munstead Lavender: This is a fantastic choice for beginners. It’s a compact English lavender variety that stays relatively small and produces abundant fragrant blooms. It’s known for being quite hardy and tolerates a variety of conditions well, making it forgiving for new indoor gardeners.
- Hidcote Lavender: Similar to Munstead, Hidcote is another popular English lavender that is well-suited for containers. It features deep, rich purple flowers and a beautiful, strong scent. It also maintains a manageable size, making it ideal for windowsills and smaller spaces.
- Sharon Roberts Lavender: This is a dwarf English lavender variety, meaning it naturally stays very small. It’s perfect for tiny pots and tight spaces, offering all the fragrance and beauty of larger lavenders without the size commitment.
- Sweet Lavender (Lavandula allardii ‘Youngii’): While technically a hybrid, Sweet Lavender is known for its lovely fragrance and can be managed well in pots. It tends to be a bit more vigorous than some English lavenders but responds well to pruning.
- English Lavender (Lavandula angustifolia): Generally, most varieties of English lavender (like Munstead and Hidcote) are the best bet for indoor growing. They prefer drier conditions and can handle the limited root space of a pot more effectively than some of their cousins.
What to Avoid for Indoor Growing
Larger, more sprawling varieties, like some of the French or Spanish lavenders (Lavandula stoechas), can be more challenging indoors. They often require more space, specific humidity levels, and can become leggy or difficult to manage in pots. While beautiful, these are often best left for outdoor gardens where they have room to flourish.
Essential Care for Thriving Indoor Lavender
Once you’ve chosen your lavender variety, providing the right environment is crucial. Lavender is a Mediterranean herb, so it thrives on sunlight, good drainage, and not too much moisture. Mimicking these conditions indoors is the secret to happy plants.
1. Light: The More, The Better!
This is arguably the most critical factor for indoor lavender. Lavender needs a lot of sunlight to grow well and produce those fragrant blooms. Think of it as wanting to soak up as much sun as possible.
- South-Facing Windows: Your best bet is a bright, south-facing window that receives at least 6-8 hours of direct sunlight per day.
- West or East-Facing Windowsoles: These can work, but you might need to supplement with grow lights, especially during shorter winter days.
- Supplemental Lighting: If you don’t have enough natural light, invest in a good quality LED grow light designed for plants. Position it a few inches above your lavender for 12-16 hours a day to really boost its growth. You can find helpful guides on choosing the right grow lights from sources like the Royal Horticultural Society.
- Rotation: Rotate your pot every few days so all sides of the plant get exposure to light. This helps prevent the plant from leaning too much in one direction.
2. Watering: Less is More
Lavender hates soggy feet! Overwatering is one of the quickest ways to kill an indoor lavender plant. It prefers to dry out between waterings. This mimics its native habitat, which is often dry and well-drained.
- Check the Soil: The best way to know when to water is to feel the soil. Stick your finger about an inch or two into the soil. If it feels dry, it’s time to water. If it feels moist, wait a few more days.
- Water Thoroughly, Then Drain: When you do water, water deeply until water runs out of the drainage holes. Then, make sure to empty the saucer. Never let the pot sit in standing water.
- Frequency: This might mean watering once a week, or even less frequently, depending on your home’s humidity, temperature, and the pot size. In winter, you’ll water much less.
- Avoid Misting: Unlike some tropical plants, lavender doesn’t benefit from misting and can even develop fungal issues if its leaves are kept consistently wet.
3. Soil: Drainage is Key
Lavender needs well-draining soil. Regular potting mix can hold too much moisture, leading to root rot. You need to create a gritty, airy mix that allows water to pass through quickly.
- Potting Mix: Start with a high-quality, well-draining potting mix.
- Amendments: To improve drainage, mix in perlite, coarse sand, or fine gravel. A good recipe is about 2 parts potting mix to 1 part perlite or sand.
- Terracotta Pots: Consider using unglazed terracotta pots. They are porous and allow the soil to dry out faster than plastic pots, which is a big plus for lavender. Be sure they have drainage holes!
You can also find specialty cactus or succulent mixes, which are designed for excellent drainage and can be a good base for your lavender soil blend.
4. Temperature and Airflow
Lavender prefers moderate temperatures and good air circulation. It’s quite tolerant of heat, but extreme cold can be an issue for some varieties.
- Ideal Range: Most indoor lavenders do well in temperatures between 65-75°F (18-24°C) during the day. They can tolerate cooler temperatures at night.
- Avoid Drafts: Keep them away from cold drafts from windows or doors in winter, and also away from direct heat sources like radiators or heating vents.
- Good Airflow: Proper airflow helps prevent fungal diseases. If your home is very stuffy, a small fan on a low setting for a few hours a day can help.
5. Potting and Repotting
Choosing the right pot size and repotting at the correct time helps keep your lavender healthy and promotes growth.
- Initial Potting: Start with a pot that is only slightly larger than the root ball of your young plant. Lavender likes to be a little snug.
- Drainage Holes: Always ensure your pot has drainage holes. This is non-negotiable!
- When to Repot: Repot your lavender when it outgrows its current container, usually every 1-2 years. Look for roots coming out of the drainage holes, or the plant drying out very quickly.
- Repotting Time: The best time to repot is in the spring, just as new growth begins.
- Pot Size: When repotting, choose a pot that is only 1-2 inches larger in diameter than the current one. Again, avoid overly large pots, which can lead to overwatering.
6. Fertilizing: Be Gentle
Lavender is not a heavy feeder and actually prefers soil that isn’t too rich. Over-fertilizing can lead to lush foliage but fewer blooms and can make the plant more susceptible to pests and diseases.
- Frequency: Fertilize sparingly, if at all. Once or twice during the spring and summer growing season is usually sufficient.
- Type of Fertilizer: use a balanced, water-soluble fertilizer diluted to half or quarter strength. You can also use a compost tea.
- Avoid Nitrogen: Too much nitrogen promotes leafy growth at the expense of flowers, which is the opposite of what we want for lavender.
7. Pruning for Shape and Blooms
Pruning is important for maintaining a compact shape, encouraging bushy growth, and promoting more flowers. It also helps prevent the plant from becoming woody and leggy.
- When to Prune: Prune after the main flowering period is over, typically in late summer or early fall. You can also do a lighter prune in early spring to shape the plant.
- How to Prune: Cut back about one-third of the plant’s growth, making sure to cut just above a set of leaves. Avoid cutting into old, woody stems where there are no leaves, as it may not regrow from there.
- Deadheading: Remove spent flower stalks regularly to encourage more continuous blooming.
Troubleshooting Common Indoor Lavender Problems
Even with the best care, you might encounter a few issues. Here’s how to tackle them:
Yellowing Leaves
Yellow leaves can be a sign of several things, but the most common culprits for lavender are overwatering or poor drainage.
- Check Watering: Ensure you are letting the soil dry out between waterings.
- Check Drainage: Make sure your pot has holes and the soil is well-draining. If the soil is constantly soggy, repot into a mix with more perlite or grit.
- Light: In some cases, insufficient light can also contribute to yellowing.
Leggy Growth
If your lavender is stretching out with long, weak stems and few leaves, it’s not getting enough light. Pruning can help, but the primary solution is more light.
- Increase Light: Move to a sunnier spot or add grow lights.
- Prune Back: Cut back the leggy stems to encourage bushier growth from the base.
No Flowers
A lack of blooms is frustrating, but usually fixable. It often comes down to light or nutrients.
- Not Enough Light: This is the most common reason. Lavender blooms best with at least 6-8 hours of direct sun.
- Over-fertilizing: Too much nitrogen can promote leaves over flowers.
- Pruning: Ensure you prune correctly after flowering to encourage future blooms.
- Age/Maturity: Very young plants may need a year or two to mature before flowering profusely.
Pests
Indoor lavender is generally less prone to pests than outdoor plants, but aphids, spider mites, or mealybugs can still appear.
- Inspection: Regularly inspect your plant’s leaves and stems.
- Treatment: For mild infestations, you can often wipe pests off with a damp cloth or spray the plant with a gentle insecticidal soap. Ensure good airflow and proper watering, as stressed plants are more susceptible.
Harvesting Your Indoor Lavender
The reward for all your care is beautiful, fragrant lavender! Harvesting can be done throughout the blooming season.
- When to Harvest: The best time to harvest is when the flower buds are plump and just starting to open. The scent is usually strongest at this point.
- How to Harvest: Use clean, sharp scissors or pruning shears. Cut the stems just above a set of leaves. You can harvest whole flower stalks.
- Uses: Dried lavender can be used in sachets, potpourri, herbal teas, or culinary dishes (ensure your variety is culinary safe). Fresh sprigs can add fragrance to a room or be made into simple bouquets.

Frequently Asked Questions about Indoor Lavender
Q1: Can any lavender plant be grown indoors?
While many lavender varieties can be kept indoors, it’s best to choose compact, English lavender types (like Munstead or Hidcote) as they are more suited to container living and controlled environments. Very large or sprawling varieties can be more challenging.
Q2: How much light does indoor lavender really need?
Lavender absolutely thrives on light. Aim for a minimum of 6-8 hours of direct sunlight daily. A bright, south-facing window is ideal. If you can’t provide this naturally, supplemental grow lights are essential for healthy growth and flowering.
Q3: My lavender is getting leggy. What am I doing wrong?
Leggy growth is almost always a sign of insufficient light. Your plant is stretching to reach for more sun. Move it to a brighter spot and consider using a grow light. Pruning the leggy stems back can also encourage bushier growth from below.
Q4: How often should I water my indoor lavender?
This is where many beginners go wrong! Lavender hates constantly wet feet. Allow the soil to dry out completely between waterings. Stick your finger about two inches into the soil – if it feels dry, it’s time to water. This might be once a week, or even less often, depending on your home’s conditions.
Q5: My lavender isn’t flowering. What should I do?
The most common reason for no flowers is not enough light. Ensure your plant is getting at least 6-8 hours of direct sun. Other causes could be over-fertilizing (too much nitrogen), incorrect pruning, or the plant may be too young to flower profusely. Be patient and ensure its basic needs are met.
Q6: Can I grow lavender in a regular potting mix?
Regular potting mix can hold too much moisture for lavender. It’s crucial to use a well-draining soil. Amend your potting mix with at least 30-50% perlite, coarse sand, or fine gravel to ensure excellent drainage and prevent root rot.
Q7: How do I know when my indoor lavender is healthy?
A healthy indoor lavender will have vibrant green or grey-green foliage, a compact, bushy shape (with proper pruning), and produce fragrant blooms during its flowering season. If it looks droopy, dull, or is constantly drying out extremely fast, assess your watering, light, and soil conditions.
