Why is my lavender woody?

Lavender naturally becomes woody at the base as it ages, which is a normal part of its growth cycle.

How often should I prune?

Prune once a year after flowering to maintain shape and prevent the center from becoming too bare.

Care

Plant your lavender in soil that drains very well to avoid root rot. Keep an eye out for yellowing leaves, which often signal that the plant is sitting in too much moisture. Pruning after the first bloom helps keep the plant tidy and encourages a second flush of flowers.

Watering: Allow the soil to dry out completely between waterings to prevent root issues.
Feeding: Apply a light, balanced fertilizer once in the early spring.
Pruning: Trim back the woody stems after flowering to maintain shape and prevent legginess.
Repotting: Repot only when the plant becomes root bound, as they prefer to be slightly snug.

Temperature: -15 to 35°C

Safety

People: Lavender is generally considered non-toxic to humans, though large amounts can cause mild digestive upset.
Pets: Lavender is toxic to cats and dogs if ingested in large quantities.
Children: The plant is not inherently dangerous, but the stems can be slightly prickly and the flowers may attract many stinging bees.
Contact allergens: Some people may experience skin irritation or contact dermatitis from the essential oils in the foliage.
Airborne allergens: The strong fragrance can trigger sensitivities or headaches in those prone to scent-based allergies.
Edibility: Only use culinary grade lavender for cooking, as some ornamental varieties may be treated with pesticides or have a soapy flavor.

Growing it

Propagation: cuttings, seed
When to plant: spring, early autumn
Overwintering: Ensure the soil is well-drained to prevent winter rot. In very cold areas, you can mulch around the base, but keep it away from the woody stems.
In containers: Lavender grows well in pots provided you use a gritty, fast-draining potting mix and a container with large drainage holes.

Softwood Cuttings

Take a 10 cm cutting from a non-flowering shoot in late spring.
Strip the leaves from the bottom half.
Insert into a pot with moist, sandy compost.
Keep in a bright spot out of direct sun until rooted.

Thyme — This herb thrives in the same dry, sunny conditions as lavender.
Sedum — These succulents provide a nice textural contrast while needing little water.

Similar species

Russian Sage — It offers a similar airy, purple look but is more tolerant of cold.
