Why Indoor Lavender Might Be Tricky (And How to Fix It!)

Lavender, the beautiful fragrant herb we all adore, usually thrives under the warm sun in well-drained soil. Bringing it inside means we have to mimic those perfect conditions as best we can. The most common challenges for indoor lavender are:

Not enough light: Lavender craves sunshine! Indoor light can be much weaker.
Overwatering: This is a big one! Lavender hates soggy feet and can quickly develop root rot.
Poor air circulation: Stagnant air can encourage pests and diseases.
The wrong soil: Lavender needs soil that drains quickly, just like it would in a garden bed.

But the good news is, these are all very manageable issues. By understanding what lavender needs and providing it, you’ll set yourself up for success. We’ll walk through each step to make sure your indoor lavender is as happy as can be.

Choosing the Right Lavender Variety for Indoors

Not all lavenders are created equal when it comes to indoor growing. Some varieties are naturally more compact and better suited for containers. When you’re shopping, look for these:

Munstead Lavender: A dwarf variety known for its compact growth and prolific blooms.
Hidcote Lavender: Another excellent dwarf English lavender with deep purple flowers.
Little Lottie Lavender: A sweet dwarf lavender with pale pink flowers, perfect for smaller spaces.
Lady Pine Lavender: This variety has a more upright growth habit and can do well indoors.

Avoid larger, more sprawling varieties as they will quickly outgrow indoor pots and might be harder to manage. Asking your local nursery for “dwarf” or “compact” lavender varieties is always a good bet.

Essential Supplies for Indoor Lavender Care

Before you get started, let’s gather what you’ll need. Having the right tools makes the whole process smoother and more enjoyable, especially for beginners!

Potting Essentials:

Container: Choose a pot with drainage holes! Terracotta or ceramic pots are great because they allow the soil to breathe and dry out. Aim for a pot that’s about 6-8 inches in diameter for a young plant.
Potting Mix: This is crucial for lavender. You need a mix that drains incredibly well. A good option is to use a cactus or succulent mix, or create your own by combining regular potting soil with perlite or coarse sand (about a 2:1 ratio of soil to perlite/sand).
Watering Can: A can with a fine spout is best for controlled watering.
Pruning Shears or Scissors: For trimming and shaping your plant.

Light & Air:**

Sunny Spot: The brightest window you have, ideally south-facing.
Grow Light (Optional but Recommended): Especially if you don’t have a very sunny window. LED grow lights are energy-efficient and effective. You can find great options on sites like Greenhouse Megastore, a reputable source for horticultural supplies that often feature detailed product information and reviews.

Step-by-Step Guide: Repotting Your Lavender Plant

When you first bring your lavender home, or if it’s outgrown its current pot, repotting is key to healthy growth. For beginners, this might sound daunting, but we’ll break it down into easy steps.

Step 1: Prepare Your New Pot

Select a pot that is only about 1-2 inches larger in diameter than the current one. Ensure it has plenty of drainage holes at the bottom. If the pot doesn’t have holes, you’ll need to drill some or choose a different pot. Good drainage is non-negotiable for lavender.

Step 2: Create the Perfect Potting Mix

Fill the bottom of your new pot with your well-draining potting mix. Remember, lavender needs to feel almost dry between waterings. A mix designed for succulents or cacti is a great base. You can also make your own by mixing 2 parts regular potting soil with 1 part perlite or coarse horticultural sand.

Step 3: Gently Remove the Lavender

Carefully take your lavender plant out of its old pot. If it’s stuck, you might need to tap the sides of the pot or gently loosen the soil around the edges with a knife. Try not to disturb the roots too much. If the roots are tightly coiled (root-bound), you can gently tease them apart a little with your fingers, but don’t force it.

Step 4: Position the Plant

Place the lavender plant in the center of the new pot. The top of the root ball should be about an inch below the rim of the pot. This leaves space for watering.

Step 5: Fill with Soil

Add more of your well-draining potting mix around the root ball, gently firming it down as you go. Make sure there are no large air pockets. The soil level should be consistent with how it was in the old pot; don’t bury the stem deeper.

Step 6: Water Lightly

Water your repotted lavender lightly. You want the soil to be moist, but not saturated. Allow any excess water to drain freely from the bottom holes.

Step 7: Find the Best Spot

Place your freshly repotted lavender in its new, sunny home. We’ll talk more about light in the next section!

The Golden Rule: Light, Light, and More Light!

Lavender plants are sun-worshippers. Indoors, this means finding the sunniest spot you possibly can. Think of it as giving your plant a daily dose of sunshine therapy!

South-Facing Window: This is your prime real estate. A south-facing window typically receives the most direct sunlight throughout the day, which is exactly what lavender craves.
East or West-Facing Windows: These can work too, especially if they get several hours of direct sun. An east window will give you morning sun, while a west window provides afternoon sun.
Signs of Insufficient Light: If your lavender starts to look leggy (long, weak stems with leaves spaced far apart) or your blooms are sparse, it’s likely not getting enough light.

Boosting Light with Grow Lights

Let’s be honest, even the sunniest indoor window might not provide enough rays for lavender, especially during shorter winter days. This is where a good grow light can be a total game-changer.

Type of Grow Light: Full-spectrum LED grow lights are excellent. They mimic natural sunlight and are energy-efficient. You can get clip-on lights for individual plants or larger fixtures for multiple plants.
Placement: Position the grow light about 6-12 inches above your lavender plant. Adjust the height as the plant grows.
Duration: Aim to provide about 10-12 hours of light per day. You can use a timer to ensure consistency.

Here’s a quick look at how different window directions might perform:

Window Direction	Sunlight Exposure	Suitability for Lavender
South	Most direct, strongest sunlight (6+ hours)	Excellent
West	Direct afternoon sun (4-6 hours)	Good, especially in summer
East	Direct morning sun (4-6 hours)	Good, especially in summer
North	Indirect, diffused light (minimal direct sun)	Poor for blooming, may survive but won’t thrive

If your home lacks adequate natural light, investing in a grow light will significantly increase your chances of success. For more information on choosing the right grow lights, resources from university extension offices, such as those found on Iowa State University Extension and Outreach, offer valuable scientific insights into horticultural lighting.

The Art of Watering Lavender Indoors

This is where most indoor lavender plants meet their match. Lavender prefers to dry out between waterings. Overwatering leads to root rot, a common killer of this Mediterranean herb.

Check the Soil First: Stick your finger about an inch or two into the soil. If it feels dry, it’s time to water. If you feel any moisture, wait longer.
Water Deeply, Less Often: When you do water, water thoroughly until water runs out of the drainage holes. This encourages roots to grow deeper.
Empty the Saucer: Never let your pot sit in standing water. Discard any excess water from the saucer after about 30 minutes.
Reduce Watering in Winter: During the cooler, darker months, your lavender will need even less water.

A good rule of thumb is to water about once every 1-2 weeks, but always check the soil moisture first. It’s much better to underwater lavender than overwater it.

Soil & Drainage: The Foundation of Success

As we’ve touched on, soil is critical. Lavender thrives in lean, gritty, well-draining soil. Garden soil typically holds too much moisture and can become compacted in pots.

What to Use:

A commercial cactus/succulent mix.
A homemade blend: 2 parts organic potting soil, 1 part perlite, 1 part coarse sand or pumice.
Adding a top dressing of small gravel or pebbles can also help with drainage and aeration around the base.

Ensure your pot has drainage holes! This cannot be stressed enough. If you’re using a decorative pot without holes, you can either drill them yourself or use it as a cachepot – place your lavender in its plastic nursery pot (with drainage) inside the decorative pot, and remove the inner pot to water. This prevents water from accumulating at the bottom.

Temperature and Humidity Needs

Lavender originated in the Mediterranean, so it enjoys warmth and lower humidity. Most average indoor home temperatures are perfectly fine for lavender.

Ideal Temperature: Lavender prefers temperatures between 65-70°F (18-21°C) during the day and can tolerate slightly cooler temperatures at night. They can handle short periods of heat.
Avoid Extremes: Keep your lavender away from drafty windows in winter or direct blasts from heating vents, which can dry it out too quickly or cause stress.
Humidity: Lavender doesn’t like high humidity. If your home is very humid, ensure good air circulation. Opening a window occasionally or using a small fan can help.

You can even consider placing your potted lavender on a tray filled with pebbles and water. As the water evaporates, it increases humidity around the plant, but make sure the bottom of the pot is not sitting directly in the water.

Feeding Your Indoor Lavender

Lavender isn’t a heavy feeder. In fact, too much fertilizer can lead to weak, leggy growth with fewer flowers.

When to Fertilize: Feed only during the active growing season, which is typically spring and summer.
What to Use: Use a balanced, dilute liquid fertilizer or a fertilizer formulated for herbs or flowering plants. A good option is a fertilizer with a lower nitrogen (N) number. For instance, a 5-5-5 or a 10-10-10 diluted to half strength.
How Often: Fertilize sparingly, perhaps once a month during spring and summer.
Skip in Fall/Winter: Do not fertilize during the fall and winter months when the plant is resting.

Over-fertilizing is a common mistake that can actually harm your plant. It’s better to under-fertilize than over-fertilize lavender.

Pruning for Health and Abundance

Regular pruning is essential for keeping your indoor lavender looking tidy, encouraging bushier growth, and promoting more blooms. Don’t be afraid to grab those scissors!

When to Prune:

After Flowering: Once the flowers have faded, prune back the spent flower stalks to about an inch above the leaves. This prevents the plant from putting energy into seed production and encourages it to produce more flowers.
In Spring: Give your plant a good trim in early spring before new growth really takes off. Cut back about one-third of the plant, shaping it to be more compact and rounded. Avoid cutting into old, woody stems if possible, as they may not regrow.
Throughout the Year: You can trim off any leggy stems or remove dead foliage as needed.

Pruning encourages the plant to branch out, resulting in a fuller, more attractive plant with more flower-producing stems.

Common Pests and Problems (And How to Deal With Them!)

Indoor plants can sometimes attract pests. Fortunately, lavender is fairly resistant, but it’s good to know what to look out for.

Aphids: Small, green or black insects that cluster on new growth.

Solution: Wipe them off with a damp cloth, spray with insecticidal soap, or rinse the plant with a strong stream of water. A solution of insecticidal soaps can be very effective and is a safer option for home use.

Spider Mites: Tiny mites that create webbing and cause stippling on leaves. They thrive in dry conditions.

Solution: Increase humidity, wipe the leaves, or spray with insecticidal soap. Regularly misting your plant (away from the direct sun) can deter them.

Root Rot: Caused by overwatering and poor drainage.

Solution: The best defense is prevention! Ensure excellent drainage and let the soil dry out between waterings. If caught early, you may be able to repot into dry, well-draining soil, trimming away any rotted roots.

Powdery Mildew: A white, powdery fungus on leaves, often due to poor air circulation and high humidity.

Solution: Improve air flow, reduce humidity, and remove affected leaves. A fungicide can be used if the problem is severe.

Regular inspection of your plant can help you catch any issues early, making them much easier to manage.

Harvesting Your Indoor Lavender

The joy of growing lavender indoors is being able to snip fresh stems whenever you please! Freshly cut lavender can be used in many ways.

When to Harvest: The best time to cut lavender is when the flower buds are just starting to open but before they are fully bloomed. This is when the essential oils are most concentrated.
How to Harvest: Use sharp scissors or pruning shears to cut the stems. Cut them long enough for your intended use.
Using Fresh Lavender:

In Potpourri: Dry the stems and use them in homemade potpourri or sachets.
In Craft Projects: Bunches of lavender are beautiful in vases or used in DIY crafts.
Culinary Use: Ensure you are using culinary varieties of lavender (like English Lavender) and that they have not been treated with pesticides. Use sparingly in cooking, as the flavor can be strong.
Aromatherapy: Simply enjoy the calming scent by a sunny window or by your bedside.

To dry lavender, bundle stems together and hang them upside down in a cool, dark, well-ventilated area. Once dried, you can strip the flower heads off the stems.

Bringing Dormancy into Play (Optional but Helpful!)

True English lavender varieties benefit from a period of dormancy, much like they would experience outdoors during winter. If you want to encourage more prolific blooming and a healthier plant over time, you can simulate this.

When: Typically from late
