A hornbeam hedge is absolutely winter hardy, at least when it is well established. Nevertheless, it makes sense to take a few care measures before winter so that the hedge survives the cold season well. Tips for caring for hornbeam hedges in winter.
How do I care for a hornbeam hedge in winter?
Hornbeam hedges are hardy and generally do not require winter protection. However, it is advisable to cover the ground with a layer of mulch and, in dry winters, to water occasionally on frost-free days. The fallen leaves serve as a natural layer of mulch and fertilizer.
Hornbeams are hardy
Hornbeams are native plants that belong to the birch family. Just like them, they can cope with temperatures as low as minus 20 degrees without any problem.
In principle, winter protection is not necessary; the trees can survive even severe frost for some time without additional protection.
Nevertheless, it makes sense to prepare the hornbeam hedge for winter. However, they should not be cut before winter. The last cut takes place in July or August at the latest.
Watere occasionally in dry winters
Hornbeam hedges tolerate drying out of the soil very poorly. In very dry winters it is therefore advisable to water young hornbeam hedges occasionally.
We only water on frost-free days, and only so little that there is no chance of waterlogging.
Protect the soil with a layer of mulch
Experienced gardeners always protect the bottom of the hornbeam hedge with a layer of mulch
- ripe compost
- Leaves
- Lawn cutting
- Straw.
The mulch keeps moisture in the soil and prevents the hornbeams from drying out in winter. At the same time, it keeps the soil surface nice and loose. It also protects the plant roots from excessive frost if temperatures drop significantly over a long period of time.
Do not sweep up the leaves of hornbeam hedges
It is a special feature of hornbeam hedges that the dried leaves stay on the trees for a very long time. The last ones only fall off when the hornbeam sprouts in spring.
The fallen leaves should not be picked up but left on the ground. It fulfills the function of a natural mulch cover.
The leaves prevent weeds from emerging, making it much easier to care for the hornbeam hedge. Additionally, the leaves decompose over time and release nutrients. They thus form a natural fertilizer.
Tip
You should always protect freshly planted hornbeam hedges from frost with a layer of mulch. The delicate roots have not yet penetrated deep enough into the earth. If they dry out, the hornbeam will die.
