Lavender is an aromatic subshrub valued for its fragrant flowers and easy-care nature. It is ideal for sunny locations and dry soils, where it adds accents with its blue-violet blooms and attracts bees. Lavender is not only an ornamental plant but is also used in the kitchen, for fragrance extraction, and in folk medicine.

sparingly after establishment

at the root zone

Waterlogging is one of the main causes of failure.

very light

as needed

Lean soil supports compact, aromatic plants.

Lavender is perennial and remains in place for 5-10 years. Not suitable for crop rotation, but as a permanent planting in perennial beds, herb spirals, or rock gardens. Keep at least 40 cm distance from other plants.

1. Sucking insects (aphids, whiteflies)
2. Spittlebugs

1. Fungal diseases (root rot, grey mold, leaf spot)

1. Site selection: Full sun, warm, and well-ventilated.
2. Soil: Well-drained, lean, and calcareous.
3. Watering: Absolutely avoid waterlogging, water only during prolonged drought.
4. Pruning: Regular pruning promotes vitality and prevents woodiness.
5. Spacing: Ensure adequate spacing for good air circulation.

Look for wilting leaves, discolorations, unusual growth patterns, or visible pests. Most problems with lavender are due to incorrect site conditions or overwatering.

Lavender is a perennial subshrub that sprouts in spring and flowers in summer. The flowering period can be extended by pruning.

Once annually for flowers, continuously for leaves.

1. Flowers: Fully open but not yet faded.
2. Leaves: Young and fresh, before woody growth.

Hang flowers and leaves to dry or spread them on a rack. Protect from direct sunlight. Store in airtight containers after drying.

Store dry, cool, and dark.

Dried flowers and leaves: 1-2 years. Essential oil: Several years with proper storage.

1. Drying
2. Distillation for essential oil
3. Infusion in oil or alcohol
4. Use as a spice

In usual culinary amounts, lavender is considered safe. Excessive consumption or ingestion of large amounts of essential oil can lead to gastrointestinal upset. Pregnant and breastfeeding women should exercise caution.

Young leaves can be consumed raw in small quantities. Flowers are usually processed dried or fresh in dishes.

Lavender is a robust, perennial subshrub that requires little special training or shaping. The main care consists of regular pruning to promote flowering and a compact growth habit.

Lavender is an excellent food source for bees, bumblebees, and other pollinating insects. Its flowers provide nectar and pollen, contributing to local biodiversity. The plant itself offers little shelter or food for other wildlife.

In early spring (March/April), the most important pruning is done to rejuvenate the plant and prepare it for flowering. Young plants can be planted out if needed.

The main flowering period is from June to August. After flowering, cut back the spent stalks to encourage reblooming. Harvest flowers regularly for fragrance and culinary use.

A light pruning can be done again in autumn if necessary to maintain shape. Autumn planting is also possible.

In harsh areas, light winter protection (e.g., with brushwood) is advisable to protect the plant from severe frost. Absolutely avoid waterlogging.
