Taking care of a lavender tree indoors is absolutely possible when you give it the right light, soil, and airflow.
These fragrant beauties, often shaped into little standards with a woody trunk and a mop of silvery foliage on top, can thrive inside your home if you treat them like the Mediterranean sun-worshippers they are.
The trick is understanding that a lavender tree indoors isn’t just a houseplant—it’s a plant that wants to pretend it’s still living on a sunny hillside in Provence.
In this post, we’ll walk through exactly how to take care of a lavender tree indoors, from watering and pruning to dealing with pests and humidity.
Let’s get your lavender tree happy and healthy inside.
How to Take Care of a Lavender Tree Indoors: The Basics
Learning how to take care of a lavender tree indoors starts with getting the fundamentals right.
Lavender trees indoors have specific needs that differ from most tropical houseplants.
If you can nail these basics, the rest of lavender tree care indoors becomes much easier.
Here’s what matters most:
1. Give It All the Sunlight You Can
Lavender trees indoors need at least six to eight hours of direct sunlight every single day.
A south-facing window is your best bet for a lavender tree indoors.
If that’s not available, a west-facing window works too, but you may need a grow light to supplement.
When caring for a lavender tree indoors, rotate the pot every few days so all sides get even light.
Without enough sun, your lavender tree will get leggy, weak, and refuse to bloom.
2. Use Well-Draining Soil and a Terracotta Pot
The number one killer of a lavender tree indoors is soggy roots.
Lavender hates wet feet, so plant yours in a mix that drains fast.
A blend of potting soil, sand, and perlite works beautifully for how to take care of a lavender tree indoors.
Terracotta pots are ideal because they wick away extra moisture through the walls.
Always make sure your pot has drainage holes, and never let your lavender tree sit in a saucer of standing water.
3. Water Deeply but Infrequently
When you take care of a lavender tree indoors, watering is where most people go wrong.
Wait until the top two to three inches of soil are completely dry before watering again.
Then water thoroughly until it runs out the bottom of the pot.
In winter, cut back even more—your lavender tree indoors might only need water every two to three weeks.
Sticking your finger in the soil is the simplest test when figuring out how to take care of a lavender tree indoors.
4. Keep Humidity Low and Air Moving
Lavender trees indoors come from dry, breezy climates, so high humidity is their enemy.
Most homes are fine, but if your bathroom or kitchen is steamy, keep your lavender tree out of there.
A small fan on low, or just a crack in the window, helps with air circulation.
Good airflow prevents the fungal issues that plague a lavender tree indoors in stuffy rooms.
Pruning and Feeding Your Lavender Tree Indoors
Once the basics are handled, learning how to take care of a lavender tree indoors means keeping it shaped and fed.
This is where your lavender tree goes from surviving to thriving.
1. Prune After Flowering
A lavender tree indoors needs regular trimming to keep that tidy standard shape.
After the flowers fade, cut back about one-third of the green growth.
Never cut into the old woody trunk, because it rarely regrows.
Light pruning throughout the season also helps a lavender tree indoors stay bushy instead of spindly.
2. Fertilize Sparingly
When you take care of a lavender tree indoors, less fertilizer is more.
Feed once in spring with a balanced, slow-release fertilizer diluted to half strength.
Too much food makes a lavender tree indoors produce soft, floppy growth with fewer blooms.
If in doubt, skip the fertilizer—lavender trees indoors actually prefer lean soil.
3. Watch for Pests and Root Rot
Spider mites and whiteflies are the usual suspects on a lavender tree indoors in dry indoor air.
Wipe leaves with a damp cloth and treat infestations with neem oil.
Yellowing lower leaves usually mean overwatering, the most common mistake in how to take care of a lavender tree indoors.
So, How Do You Take Care of a Lavender Tree Indoors?
Taking care of a lavender tree indoors comes down to mimicking its natural Mediterranean home.
Give it tons of sunlight, fast-draining soil, infrequent deep watering, low humidity, and good airflow.
Prune it after flowering, fertilize lightly, and keep an eye out for pests and soggy roots.
When you take care of a lavender tree indoors with these simple habits, it will reward you with silvery foliage and those unmistakable fragrant purple blooms.
Enjoy your little slice of Provence right there on your windowsill.
