Lavender Care Guide: Grow Fragrant Lavandula Indoors and Outdoors

Overview

If there's one herb that truly transforms a garden, it's lavender. Known for its unmistakable scent and striking purple spikes, this Mediterranean native is a magnet for bees and butterflies. While it looks delicate, it's actually incredibly tough—provided you give it the right environment.

Lavender is famously easy to grow once established, but it has a reputation for dying suddenly because many people treat it like a typical thirsty garden flower. It prefers life on the dry side.

Light and Placement

Lavender is a sun-worshipper. It needs a minimum of 6 to 8 hours of direct, blazing sun every day. If you plant it in the shade, it will get leggy, lean toward the light, and refuse to flower.

Airflow is just as important as sunlight. Don't crowd your lavender plants too close to walls or other leafy shrubs. They need a breeze to keep their foliage dry and prevent fungal diseases.

Watering Strategy

Overwatering is the number one killer of lavender. These plants evolved in the dry, rocky hills of the Mediterranean, meaning they hate "wet feet." Let the soil dry out completely between waterings. If you stick your finger into the soil and feel any moisture, walk away.

If you're growing it in a pot, make sure you use an unglazed terracotta pot, which allows the soil to breathe and dry out faster.

Soil and Potting Mix

Forget the rich, dark potting soil you use for your houseplants. Lavender wants poor, gritty, fast-draining soil. Mix standard potting soil with generous amounts of coarse sand, perlite, or even gravel.

It also prefers slightly alkaline soil. If your garden has heavy clay or highly acidic soil, you're better off growing your lavender in raised beds or containers where you can control the drainage.

Pruning and Maintenance

To keep your lavender looking like a neat, compact mound rather than a sprawling, woody mess, you have to prune it. Grab your shears right after the first flush of flowers fades in late summer. Cut the green growth back by about one-third.

A critical rule: never cut down into the old, brown, leafless wood. Lavender cannot easily generate new shoots from old wood, and cutting too deep can kill that section of the plant permanently.
