Choosing the Right Lavender for Indoor Living
Not all lavender varieties are created equal when it comes to thriving indoors. While they all love sunshine, some are more adaptable to container life and the slightly less intense conditions of a typical home.
The key is to select varieties known for their compact growth habit and tolerance for drier indoor air.
Best Lavender Varieties for Indoor Cultivation
- English Lavender (Lavandula angustifolia): Often considered the gold standard for its strong fragrance and beautiful blooms. Varieties like ‘Munstead’ and ‘Hidcote’ are more compact and do well in pots. They are relatively cold-hardy but appreciate a warm, sunny spot indoors.
- French Lavender (Lavandula dentata): Recognizable by its serrated, tooth-like leaves and unique flower spikes, French lavender is more tolerant of humidity and can be a good choice. It tends to be a bit larger, so look for smaller cultivars.
- Spanish Lavender (Lavandula stoechas): With its distinctive “bunny ear” bracts, Spanish lavender is visually striking. Some compact cultivars can be grown indoors, but they generally prefer more heat and sun than English varieties.
I’ve found that ‘Munstead’ is often the most forgiving and rewarding choice for beginners looking to grow lavender as a houseplant. Its compact size and robust nature make it an excellent candidate.
Lavender as a Houseplant: The Ideal Indoor Environment
The secret to a flourishing indoor lavender plant lies in replicating its natural Mediterranean habitat as closely as possible. Think bright, sunny, and well-ventilated conditions.
Don’t worry—it’s more achievable than you might think!
Sunlight Requirements for Potted Lavender
Lavender is a sun worshipper. It needs at least six to eight hours of direct sunlight per day to thrive and bloom indoors. A south-facing window is usually your best bet.
If natural light is scarce, don’t despair! A good quality LED grow light can be a fantastic substitute. Position it about 6-12 inches above your plant for 10-12 hours daily.
Temperature and Air Circulation
Indoor lavender prefers cool to moderate temperatures, ideally between 60-70°F (15-21°C) during the day and slightly cooler at night. Avoid placing it near heat vents or drafty windows.
Good air circulation is crucial to prevent fungal diseases, which lavender is susceptible to in humid, stagnant conditions. Open a window occasionally or use a small fan on a low setting to gently circulate the air around your plant.
Choosing the Right Container
The pot you choose makes a big difference. Lavender absolutely hates “wet feet,” meaning its roots sitting in soggy soil. Opt for a pot with excellent drainage.
Unglazed terracotta pots are ideal because they are porous and allow moisture to evaporate through their walls, preventing overwatering. Choose a pot that’s at least 8-12 inches in diameter to give the roots room to grow.
Mastering the Art of Watering and Humidity
This is perhaps the most critical aspect of caring for lavender as a houseplant. Overwatering is the number one killer of indoor lavender.
Remember its native arid climate: it prefers dry conditions between waterings.
When and How to Water Your Indoor Lavender
Always let the soil dry out significantly between waterings. To check, stick your finger about two inches deep into the soil. If it feels dry, it’s time to water.
When you do water, do so thoroughly until water drains from the bottom of the pot. Empty any excess water from the saucer immediately to prevent root rot.
In winter, when growth slows, reduce watering frequency even further.
Humidity Levels
Unlike many houseplants that crave humidity, lavender prefers drier air. This is another reason why it can do so well indoors, especially in homes with dry heating systems.
Avoid misting your lavender, as this can encourage fungal issues on the foliage.
Feeding Your Indoor Lavender: Nutrients for Success
Lavender is not a heavy feeder. In its natural environment, it thrives in relatively poor, lean soils. Too much fertilizer, especially nitrogen, can lead to lush foliage but fewer flowers and weaker plants.
Fertilizer Recommendations
Feed your indoor lavender sparingly. A balanced, slow-release granular fertilizer applied once in spring is often sufficient. Alternatively, you can use a diluted liquid fertilizer (half strength) every 4-6 weeks during the active growing season (spring and summer).
Cease fertilization entirely in fall and winter when the plant is dormant.
Soil Composition for Optimal Growth
The right soil mix is fundamental for a healthy indoor lavender. It needs to be extremely well-draining to prevent waterlogging.
Creating the Perfect Potting Mix
A standard potting mix won’t cut it alone. You’ll need to amend it significantly. Here’s a blend I recommend:
- 2 parts good quality potting mix: Choose one that’s peat-free if possible.
- 1 part perlite or coarse sand: This dramatically improves drainage.
- 1 part small gravel or grit: Further enhances drainage and aeration.
You can also add a small amount of garden lime or bone meal to slightly raise the soil pH, as lavender prefers a neutral to slightly alkaline soil (pH 6.5-7.5).
Pruning for Bushiness and Blooms
Pruning is essential for maintaining a compact shape, encouraging bushier growth, and promoting abundant flowering. Don’t be afraid to snip!
When and How to Prune
- After the first flush of blooms: Once the flowers start to fade, deadhead them by snipping the flower stalks back to the first set of leaves. This encourages a second flush of blooms.
- Early spring (main prune): Before new growth really kicks in, give your lavender a more substantial prune. Remove about one-third of the plant’s overall size, focusing on leggy or woody stems. Aim to maintain a rounded, compact shape.
Always use clean, sharp pruning shears to make clean cuts and prevent disease. Avoid cutting back into old, woody stems that have no green growth, as these rarely resprout.
Troubleshooting Common Indoor Lavender Challenges
Even with the best intentions, you might encounter a few hurdles. Knowing what to look for can help you quickly address issues and keep your lavender as a houseplant thriving.
Yellowing Leaves and Drooping
This is often a sign of overwatering or poor drainage. Check the soil moisture. If it’s soggy, let it dry out completely. Ensure your pot has drainage holes and the soil mix is appropriate.
Underwatering can also cause drooping, but the leaves will typically look crispy and dry, not soft and yellow.
Lack of Blooms
The most common reason for a lack of flowers indoors is insufficient light. Move your plant to a brighter location or supplement with a grow light.
Too much nitrogen fertilizer can also lead to lush foliage at the expense of flowers. Review your feeding schedule.
Pests and Diseases
Indoor lavender can occasionally attract pests like aphids or spider mites, especially if air circulation is poor or the plant is stressed.
- Aphids: Small green or black insects, often found on new growth. Wipe them off with a damp cloth or spray with insecticidal soap.
- Spider Mites: Tiny pests that create fine webbing. Increase air circulation and humidity (around the plant, not on the foliage) to deter them, and use insecticidal soap if needed.
Fungal issues like powdery mildew can occur if humidity is too high or air circulation is poor. Ensure good airflow and avoid overhead watering.
Repotting Your Thriving Lavender
As your lavender grows, it will eventually outgrow its pot. Repotting gives it fresh nutrients and more space for root development.
When and How to Repot
Repot your lavender every 1-2 years, typically in early spring before new growth begins. Look for signs of root bound plants, such as roots growing out of the drainage holes or the plant drying out very quickly.
- Choose a pot only one size larger than the current one.
- Gently remove the plant from its old pot.
- Loosen any circling roots at the bottom.
- Place a layer of your well-draining potting mix in the new pot.
- Center the lavender and fill around the root ball with more mix, leaving about an inch of space from the rim.
- Water thoroughly.
Enjoying Your Indoor Lavender: Beyond Just Beauty
Growing lavender indoors offers more than just visual appeal. The aromatic compounds released by the plant have numerous benefits.
Aromatherapy and Wellness
The soothing fragrance of lavender is renowned for its calming properties. It can help reduce stress, promote relaxation, and even aid in sleep.
Simply brushing against the foliage can release its delightful scent, creating a serene atmosphere in your home.
Culinary and Craft Uses
If you’re growing an English lavender variety, you can harvest the flowers for culinary uses. Add them to baked goods, infuse teas, or create lavender sugar.
Dried lavender flowers are perfect for sachets, potpourri, or homemade essential oil infusions. Just snip the flower stalks when they are fully open, tie them in small bundles, and hang them upside down in a cool, dark place to dry.
Frequently Asked Questions About Growing Lavender Indoors
Can I use any type of lavender for indoor growing?
While you can try, some varieties are much better suited than others. English lavender (‘Munstead’, ‘Hidcote’) and some compact French lavender cultivars are generally the most successful due to their smaller size and better adaptability to indoor conditions. Larger, more sprawling varieties struggle to get enough light and airflow indoors.
Why are my lavender leaves turning brown?
Brown leaves, especially crispy ones, usually indicate underwatering or extremely low humidity. If they are soft and brown, it could be a sign of root rot from overwatering. Check your soil moisture carefully. Ensure your plant is getting consistent, but not excessive, moisture.
Does indoor lavender need a dormant period?
Ideally, yes. Lavender benefits from a cooler, drier period in winter to rest before its next growing cycle. If possible, move your plant to a slightly cooler room (around 50-55°F or 10-13°C) and reduce watering significantly during these months. This mimics its natural outdoor dormancy and encourages more vigorous growth and blooms in spring.
Is lavender safe for pets indoors?
Lavender is generally considered mildly toxic to pets if ingested in large quantities, potentially causing mild stomach upset. However, most pets aren’t keen on eating large amounts of aromatic plants. It’s always best to place plants out of reach of curious pets, especially if they have a history of nibbling on houseplants.
How often should I deadhead my indoor lavender?
Deadheading, or removing spent blooms, should be done regularly throughout the flowering season. This not only keeps your plant looking tidy but also encourages it to produce more flowers instead of putting energy into seed production. As soon as a flower spike fades, snip it off at the base of the stem or just above the first set of healthy leaves.
Conclusion: Embrace the Serenity of Indoor Lavender
Bringing lavender as a houseplant into your home is a truly rewarding endeavor. With the right care—plenty of sunshine, well-draining soil, careful watering, and a little pruning—you can enjoy its captivating beauty and calming fragrance no matter the season.
It might take a bit of observation and adjustment to find the perfect spot and routine for your specific plant, but the effort is well worth it. Your home will feel more serene, and you’ll gain the satisfaction of cultivating a truly unique and beneficial indoor companion.
So, go ahead, choose your favorite compact variety, prepare its cozy pot, and embark on your journey to growing beautiful indoor lavender. Happy gardening!
