Lavender care: Practical tips
Lavender is a rewarding garden plant, but it thrives best with the right care. Whether you grow it in a border or a pot, a few simple routines will help your lavender stay healthy and bloom beautifully year after year. Below you'll find practical advice for watering, feeding, winter protection and more.
Watering: How much and when?
Lavender prefers dry conditions and is sensitive to overwatering. In the open ground, established plants usually only need extra water during prolonged drought. Check the soil before watering: if the top 2–3 cm feels dry, you can water. In pots, lavender dries out faster, so check more often—especially in warm weather. Always let the soil dry out between waterings.
Fertilising: Is it necessary?
Lavender does not need much fertiliser. Too much nutrition can even reduce flowering and make the plant leggy. If your soil is very poor, you can give a light dose of compost in early spring, but avoid rich or high-nitrogen fertilisers. In most Dutch and Belgian gardens, extra feeding is not required.
Winter protection and frost sensitivity
Most common lavenders (especially Lavandula angustifolia) are reasonably hardy in the Netherlands and Belgium, but young plants and some varieties can suffer in harsh winters. In open ground, plant lavender in a sunny, sheltered spot with well-drained soil to reduce winter damage. In very wet winters, root rot is a risk. For potted lavender, move the pot to a sheltered spot or against a south-facing wall in winter. If severe frost is expected, you can wrap the pot with fleece or bubble wrap for extra protection.
Caring for lavender in pots
Lavender in pots needs a little more attention. The soil dries out faster, so check regularly and water when the top layer is dry. Make sure the pot has drainage holes and never let water stand in the saucer. In winter, protect potted lavender from excess rain and severe frost as described above.

Frequently asked questions about lavender care
- How often should you water lavender?
- In the ground, established lavender rarely needs extra water except during long dry spells. Always check the soil first: only water when the top few centimetres are dry. In pots, check more often and water when the soil feels dry to the touch.
- Should lavender be fertilised?
- Lavender generally does not need fertiliser. Too much nutrition can harm the plant. If your soil is very poor, a small amount of compost in early spring is enough.
- Is lavender hardy in the Netherlands and Belgium?
- Most common lavender types are reasonably hardy, but young plants and some varieties may need extra protection in harsh winters. Good drainage and a sheltered spot help prevent winter damage.
- Is lavender toxic to dogs and cats?
- Lavender is considered mildly toxic to pets if eaten in large amounts, but most animals avoid it. If you suspect your pet has eaten a significant amount, or if you notice unusual symptoms, always consult your veterinarian for advice.
