Lavender is one of the most popular plants in German gardens. So that the Mediterranean flair will be spread again in the coming year, a lot has to be considered during the winter.
With its purple flowers and intense fragrance, lavender has long been one of the most popular plants both in private gardens and in many parks. The plant, which is native to the Mediterranean, not only decorates our beds, but also looks beautiful in tubs on the terrace.
However, the winters here in Germany are significantly colder than in the south, which is why you should think about wintering in good time. After all, you want to enjoy the wonderful fragrance and the blossom of the lavender again in the coming summer.
What kind of lavender is in my garden?
The trade has a few varieties of lavender. There are hardy, frost-free, frost-sensitive and winter-proof varieties of lavender. The variety therefore decides how you need to prepare the plant for winter. The real lavender is particularly hardy. Varieties such as Schopflavendel, Speiklavendel and Lavender Intermedia are more likely to be sensitive to frost. Lavender in tubs in particular must be protected from the frosty temperatures in order to survive the winter unscathed.
Cut the lavender back in time
In addition to the variety, timely pruning is also crucial to overwinter the lavender. If you cut your lavender back too late, you risk that the parts of the plant cannot mature properly and are therefore not strong enough for the winter. They freeze to death and do not form new shoots next year. (Reading tip: Cutting lavender - when and how?)
➥ The following applies: Prune your lavender right after flowering. This gives the plant enough time to harden.
The right location
Lavender likes it sunny and sheltered from the wind - at least in summer. In winter, you should make sure that the lavender does not get too much sun. In winter, the sun evaporates the water, which can cause the water in the leaves to evaporate, drying out the plant.
Lavender prone to permafrost
If there is permanent frost and the temperatures drop below -15 degrees for several days, hardy varieties are also at risk. Because permafrost doesn't like lavender. It's best to cover your beloved lavender with fleece or a coconut mat these days so that it is protected. You can also cover the ground with mulch, brushwood or leaves. So your plant is also protected from precipitation and dew.
Although lavender needs to be watered a little every now and then in winter, it is better to leave it out on frosty days (when the ground is frozen), otherwise the roots could freeze and suffer great damage.
Lavender in tubs
It is a little easier with container plants. The best protection here is the dry and cool cellar room. Garages, conservatories and stairways with little light also offer optimal shelter - as long as it is frost-free.
If you want to keep your lavender in the bucket for the winter, you should definitely choose an insulating mat as a base. Alternatively, you can also use wood or styrofoam, in any case it is important that the bucket is protected from ground frost.
