Why Bringing Lavender Indoors Can Be Tricky (And How to Fix It!)
Lavender is a plant that truly loves the great outdoors. It thrives on sunshine, breezy air, and soil that dries out quickly. That’s why bringing it inside can present a few challenges. Our homes often lack the intense sunlight lavender craves, and it’s easy to overwater them because we’re used to different indoor plant routines. These conditions can lead to legginess, poor flowering, and even root rot. But understanding these differences is the first step to success! By mimicking its natural environment as closely as possible, we can help your indoor lavender flourish.
The good news? With the right knowledge, you can overcome these indoor gardening hurdles. We’ll cover the essentials: the perfect pot, the best soil, how much light your lavender needs, and a watering schedule that keeps it happy. Plus, we’ll share secret pruning tips to keep your plant bushy and bursting with fragrant blooms. Let’s dive in and make your indoor lavender dreams a reality!
Choosing the Right Lavender for Indoor Life
Not all lavender varieties are created equal when it comes to indoor growing. Some are simply better suited to container life and can tolerate the slightly less intense conditions of an indoor environment. When you’re choosing your lavender, look for these types:
- English Lavender (Lavandula angustifolia): This is a popular choice and generally does well indoors. Varieties like ‘Munstead’ and ‘Hidcote’ are more compact and often perform better in pots.
- French Lavender (Lavandula stoechas): Also known as Spanish lavender, this variety has distinctive “bunny ear” bracts. It can adapt to indoor growing but might be slightly more sensitive to overwatering.
- Lavandin (Lavandula x intermedia): These are hybrids and tend to be larger plants. While they can be grown in pots, they generally require more space and might be better suited for a bright sunroom or greenhouse.
When purchasing, look for healthy plants with vibrant green foliage and no signs of pests or disease. It’s often best to start with a smaller, younger plant, as it will adapt more easily to your indoor conditions.
The Absolute Essentials: Light, Pot, and Soil
These three elements are the foundation for a happy indoor lavender plant. Get them right, and you’re most of the way there!
1. Sunshine is Key: The Importance of Light
Lavender absolutely adores sunlight. Indoors, this means finding the brightest spot in your home. Your plant will need at least 6-8 hours of direct sunlight per day. This is non-negotiable for healthy growth and abundant blooms.
- South-facing windows are your best bet. In the Northern Hemisphere, a south-facing window receives the most direct sunlight throughout the day.
- Supplement with grow lights if needed. If you don’t have a window that provides sufficient light, consider investing in a good quality LED grow light designed for plants. Positioning it a few inches above your lavender and running it for 10-12 hours a day can make a huge difference. You can find excellent options at reputable gardening supply stores or online retailers.
- Rotate your plant. To ensure all sides of your lavender get light, rotate the pot a quarter turn every few days. This prevents it from becoming leggy and leaning towards the light source.
2. Drainage, Drainage, Drainage: Choosing the Right Pot
This is one of the most critical factors for preventing root rot, lavender’s arch-nemesis. Lavender roots hate sitting in soggy soil.
- Must have drainage holes! This cannot be stressed enough. Ensure your pot has multiple drainage holes at the bottom.
- Terracotta is your friend. Unglazed terracotta pots are porous and allow excess moisture to evaporate through the sides, helping to keep the soil drier. They are an excellent choice for lavender.
- Size matters. Choose a pot that is appropriately sized for your plant. Too large a pot can hold too much moisture, while a pot that’s too small will restrict root growth. A pot that’s about 2 inches wider than the root ball is usually a good starting point.
- Consider a decorative cachepot. If you fall in love with a pot that doesn’t have drainage holes, you can use it as a cachepot by keeping your lavender in a plastic nursery pot with drainage holes inside it. Just remember to remove the inner pot when watering to let excess water drain away, and never let water sit at the bottom of the cachepot.
3. Sandy Soil is Best: Creating the Perfect Mix
Lavender, in its natural Mediterranean habitat, grows in rocky, lean soil that drains freely. Replicating this indoors is key.
- Avoid standard potting soil alone. Regular potting mixes are often too rich and retain too much moisture for lavender.
- Amend your potting mix. A good blend for indoor lavender is 1/3 coarse sand (horticultural sand, not play sand), 1/3 perlite, and 1/3 good quality potting mix. This creates a light, airy, and fast-draining medium.
- Look for cactus or succulent mixes. These pre-made mixes are often a good base, as they are formulated for plants that prefer drier conditions. You can then amend them further with extra perlite or sand if you feel they are still too moisture-retentive for your liking.
- Don’t fertilize heavily. Lavender prefers lean soil, so avoid over-fertilizing. Too much fertilizer can lead to weak, leggy growth and fewer blooms.
The Art of Watering: Less is More for Lavender
This is where most indoor lavender plant parents stumble. Overwatering is the quickest way to kill your beautiful herb. Lavender prefers to dry out between waterings.
How Often to Water:
There’s no strict schedule. Instead, you need to become a soil detective!
- Check the soil moisture. Stick your finger about 2 inches into the soil. If it feels dry, it’s time to water. If you feel any moisture at all, wait longer.
- Feel the weight of the pot. A dry pot will feel significantly lighter than a freshly watered one.
- Consider environmental factors. Your plant will need watering more frequently in warmer, sunnier conditions and less frequently in cooler, dimmer conditions.
How to Water:
- Water thoroughly. When you do water, water until you see it draining from the bottom of the pot. This ensures all the roots get a drink.
- Water the soil, not the leaves. Wet foliage can encourage fungal diseases, especially in an indoor environment with less air circulation.
- Empty the saucer. Never let your pot sit in a saucer full of water. This is a direct path to root rot. Discard any excess water after about 15-20 minutes.
A good rule of thumb is to water your indoor lavender only once every 2-3 weeks, but always check the soil first!
Feeding Your Lavender: A Light Touch
As mentioned, lavender thrives in lean conditions. It doesn’t require a lot of feeding. In fact, over-fertilizing can be detrimental, leading to lush foliage but very few, if any, blooms.
- During the growing season (spring and summer): Feed your lavender sparingly, perhaps once a month, with a balanced liquid fertilizer diluted to half strength. Look for a fertilizer that is not too high in nitrogen.
- In fall and winter: Do not fertilize at all during this dormant period.
- Avoid high-nitrogen fertilizers. These promote leafy growth at the expense of flowers.
Your goal is a healthy, somewhat woody plant with fragrant spikes, not a giant leafy bush. A light feeding is just to supplement the nutrients in its fast-draining soil.
Pruning for a Fuller, Bloomier Plant
Pruning is essential for keeping your indoor lavender plant compact, bushy, and encouraging more flowers. Without it, your plant can quickly become leggy and sparse.
When to Prune:
- After flowering: This is the most important time to prune. Once the flowers have faded, trim them back. This prevents the plant from putting energy into seed production and encourages new blooms.
- In spring: A light prune in early spring can help shape the plant and encourage new growth.
- Avoid heavy pruning in fall/winter: During its semi-dormant period, avoid major pruning as this can stress the plant.
How to Prune:
You’ll need a sharp, clean pair of pruning shears or scissors.
- First prune (after flowering): Cut back the flower stalks just above a set of leaves. You can cut back another inch or two below the faded flowers to encourage branching.
- Shaping prune (spring): Aim to reduce the plant’s size by about one-third. Cut back stems to just above a leaf node (where new leaves emerge). Always make your cuts at an angle.
- Deadheading: Throughout the growing season, deadhead spent flowers by snipping them off.
- Remove dead or weak stems: Any stems that look brown, dry, or spindly should be removed.
Think of pruning as shaping a beautiful hedge; you want to encourage its natural, compact form.
Pest Patrol: Keeping Troubles at Bay
Indoor plants can sometimes attract pests, but lavender is generally quite resilient. The most common invaders you might encounter are:
- Aphids: Small, green, or black insects that cluster on new growth.
- Spider Mites: Tiny, almost invisible mites that create fine webbing on the undersides of leaves.
- Whiteflies: Small, white, moth-like insects that fly up when the plant is disturbed.
Prevention and early detection are key!
What to Do:
- Inspect regularly. Make it a habit to check your plant’s leaves (tops and bottoms), stems, and soil for any signs of pests.
- Wipe down leaves. Regularly wiping down your plant’s leaves with a damp cloth can physically remove many pests and dust.
- Horticultural soap or neem oil. For mild infestations, a solution of insecticidal soap or neem oil (follow product instructions carefully!) can be very effective. You can find these at most garden centers and online. A good resource for identifying and managing common houseplant pests is the Penn State Extension.
- Improve air circulation. Pests often thrive in stagnant, humid conditions. Ensuring good airflow around your plant can help deter them.
- Isolate affected plants. If you find pests, move the affected plant away from others to prevent spreading.
Healthy plants are less susceptible to pests, so focusing on optimal light, watering, and soil will go a long way in keeping your lavender pest-free.
Troubleshooting Common Indoor Lavender Problems
Even with the best intentions, you might encounter a few hiccups. Here’s how to solve them:
| Problem | Cause | Solution |
|---|---|---|
| Yellowing Leaves | Overwatering is the most common culprit. It can also be underwatering, or nutrient deficiency (less likely). | Check soil moisture. If wet, let it dry out thoroughly. If dry, water deeply. Ensure good drainage. If it persists and soil is appropriately moist, consider a very diluted fertilizer during the growing season. |
| Leggy Growth (Long, thin stems) | Insufficient light. | Move your plant to the sunniest spot available or supplement with grow lights. Rotate the plant regularly. Prune back leggy stems to encourage bushier growth. |
| No Flowers | Lack of sufficient light, or over-fertilizing. Lavender needs lots of direct sun to bloom. | Ensure at least 6-8 hours of direct sunlight daily. Supplement with grow lights if necessary. Avoid high-nitrogen fertilizers. Prune at the right times to encourage flowering. |
| Wilting | Can be overwatering (root rot) or underwatering. If the soil is wet and the plant is wilting, it’s likely root rot. | Check soil moisture. If very wet, the roots may be rotting. Repot into fresh, well-draining soil, trimming away any mushy or black roots. If soil is dry, water thoroughly. |
| Brown Leaf Tips | Often caused by inconsistent watering, low humidity, or mineral buildup from tap water. | Ensure soil is neither too wet nor too dry. Use filtered or distilled water when possible. Improve air circulation. |
Bringing in the Outdoors: Seasonality and Care
Just because it’s indoors doesn’t mean lavender completely forgets its connection to outdoor seasons. While you’re aiming for consistent conditions, understand that your plant will respond to subtle cues.
- Growing Season (Spring/Summer): Your lavender will be actively growing, potentially flowering, and will need the most light and occasional but thorough watering. This is also when it benefits from light feeding and pruning after flowering.
- Dormant/Resting Period (Fall/Winter): Light levels naturally decrease, and temperatures might be cooler even indoors. Your lavender will naturally slow its growth. You’ll need to water even less frequently, and definitely stop fertilizing. Pruning during this time should be minimal, focusing only on removing dead growth. The key is to keep it as bright as possible even as growth slows.
Respecting this natural cycle will help your lavender stay healthy and strong, leading to better blooms when the conditions are right for it to put on a show.
FAQ: Your Indoor Lavender Questions Answered
Q1: Can I grow lavender from seed indoors?
A: While possible, starting lavender from seed indoors can be challenging and time-consuming for beginners. Seeds need stratification (a period of cold, moist conditions) and can have low germination rates. It’s generally easier and provides quicker results to buy a young plant from a nursery.
Q2: How much humidity does my indoor lavender need?
A: Lavender prefers dry air! It hails from arid Mediterranean climates. Avoid placing it in steamy bathrooms or near humidifiers. Good air circulation is more important than high humidity for lavender.
Q3: My lavender smells great but isn’t producing many flowers. What can I do?
A: This is likely due to insufficient light or over-fertilizing. Ensure it gets at least 6-8 hours of direct sunlight daily. If you’re feeding it regularly, especially with a high-nitrogen fertilizer, cut back drastically. Pruning after flowering also encourages more blooms!
Q4: Can I grow lavender in a normal houseplant pot without drainage holes?
A: It’s highly discouraged. Lavender roots are very susceptible to rot if they sit in water. Always use pots with drainage holes. If you must use a decorative pot without holes, use it as a cachepot and keep the lavender in a plastic pot with drainage inside that.
Q5: What kind of pruning should I do if my plant is already very leggy?
A: If your plant is leggy, it means it hasn’t had enough light. You can prune it back to encourage bushier growth. For leggy stems, cut them back by about one-third to one-half, just above a leaf node. This will encourage new shoots to emerge from lower down, making the plant denser.
Q6: How do I know if my lavender is getting enough light?
A: Look for signs! If your plant is stretching out with long, thin stems and sparse leaves, it’s not getting enough light (this is called etiolation). The leaves should be a healthy green color, and you should see flower buds forming during its blooming season. If it’s leaning heavily
