Lavender is one of the most popular plants in German gardens. In order for the Mediterranean flair to spread again in the coming year, a few things have to be considered during the winter.
With its purple flowers and intense fragrance, lavender has long been one of the most popular plants in both private gardens and many parks. The plant, which is native to the Mediterranean region, not only decorates our beds, but also looks beautiful in pots 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 scent and the blossom of lavender again next summer.
What kind of lavender do I have in my garden?
The trade has several varieties of lavender ready. There are hardy, frost-free, frost-sensitive and winter-hardy lavender varieties. So, the variety decides how you need to prepare the plant for winter. Real lavender is considered to be particularly hardy. Varieties such as French lavender, Spike lavender and Intermediate lavender are more sensitive to frost. Lavender in pots in particular must be protected from the freezing temperatures in order to be able to survive the winter unscathed.
Pruning back lavender in time
In addition to the variety, timely pruning is also crucial in order to be able to overwinter the lavender. If you cut back your lavender too late, you risk that the parts of the plant cannot mature properly and are therefore not strong enough for the winter. They freeze and do not form new shoots the next year. (Reading tip: Cut lavender - when and how?)
➥ The following applies: Cut back your lavender immediately 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, causing the plant to dry out.
Lavender susceptibleagainst permafrost
When there is permafrost and temperatures fall below -15 degrees for several days, then even hardy varieties are at risk. Because permafrost doesn't like lavender at all. It is best to cover your beloved lavender with fleece or a coconut mat these days so that it is protected. You can also cover the soil with mulch, sticks, or fallen leaves. This also protects your plant from precipitation and dew.
Although lavender needs a little watering even in winter, it is best not to water it on frosty days (when the ground is frozen) or the roots could freeze and be seriously damaged.
Lavender in tubs
It's a little easier with potted plants. The best protection here is the dry and cool basement room. Garages, conservatories and stairwells with little light also offer optimal shelter - as long as it is frost-free.
If you also want to let your lavender spend the winter outside in a bucket, you should definitely choose an insulating mat as a base. Alternatively, you can also use wood or styrofoam, but it is important that the bucket is protected from frost.
