Lavender can be planted in a flower bed, in a pot or in a container. Winter care for Lavender depends on the type of Lavender and the location. This is the best way to get your lavender through the cold season.

The English lavender (Lavandula angustifolia) is one of the most popular plants for flower beds. With its fragrant, blue-violet flowers, it is also a popular plant in a pot on the terrace or balcony. Since it is a Mediterranean plant, a few things need to be kept in mind during winter. Good winter protection is particularly important for potted Lavender to ensure that the plants get through the cold season undamaged. And you should also overwinter lavender properly in the bed in order to enjoy the perennial plant for a long time.

Potted Lavender can be very well protected against frost with bubble wrap (left) and jute fabric (right)

Bubble wrap is recommended as a warm cover. It is not a pretty sight, however the several small air sacs of the bubble wrap provide very good insulation. In our winter protection version, it is wrapped around the Lavender pot as the first and subsequent invisible layer. The jute fabric that follows, not only covers the bubble wrap, but also has an insulating effect. Instead of the jute fabric, you can also use a winter protection fleece up to the appropriate height - approximately 3.93 inches above the rim of the pot - and wrap it around the pot. Tie the jute fabric using a cord.

Tip: You can also put your Lavender along with the pot in a wooden box and fill it with bark mulch. Bark mulch insulates and keeps the root ball of the plant nice and warm.

Overwintering Spanish Lavender

Spanish Lavender (Lavandula stoechas) is significantly more sensitive to frost than English lavender and is therefore planted mostly in pots. Best is to overwinter it in a bright place at temperatures between 41 and 50 degrees Fahrenheit. Unheated rooms or a conservatory are the ideal during the winter months. In very mild regions, it can spend the winter outside if protection such as fir twigs or fleece is provided. However, this is only possible if the plant is well-rooted and has reached a certain age. Young Spanish Lavender cannot tolerate cold conditions.

The Spanish Lavender is very sensitive to cold conditions

In winter, the Spanish Lavender requires very little water. But like English Lavender, it should never dry out completely. In February you can start to get the plant slowly accustomed to warmer temperatures again, then later in the year it can move to its place outside without any problems. Now is the best time to repot and prune the Lavender. You can also shorten the roots slightly. The plant sprouts more vigorously in spring and summer. Don't forget to thoroughly water the Spanish Lavender in the new pot!

Winter protection in flower bed

If you plant Lavender directly in the flower bed, it is also crucial to protect it during winter. Above all, as already mentioned, it does not tolerate the cold east winds. If you are not living in a mild wine-growing region, it is advisable to cover the stems at the base with a layer of bark mulch in the fall and additionally spread a layer of pine twigs over the plant.

The right substrate for winter

All Lavender species have one thing in common: They belong to the category of plants that are very sensitive to winter wet conditions. That is why conventional potting soil is unsuitable for this subshrub. Unfortunately, this is rarely taken into account in the nurseries, because they usually cultivate all plants in the same peat-rich soil. So, repot newly purchased plants into a larger planter with herbal soil or a 1:1 mixture of potting soil and construction sand. It is also very important that the soil is well drained and that no waterlogging occurs in the flower bed.
