Make tall trunks winterproof
Due to their growth character, tree roses are much more exposed to frost than low rose bushes; In addition, the sensitive finishing point - which is located directly under the crown - cannot be protected by piling. It is particularly important to protect the crown from drying out, i.e. from winter sunlight when the ground is frozen at the same time. Most roses do not freeze to death, but rather dry up when the ground is hard frozen and the roots can no longer absorb water. For optimal winter protection, tie fir twigs in the crown to protect the sensitive finishing area and finally put a jute sack (€ 8.28 on Amazon *) or a special winter fleece over it.
Do not use plastic bags! Condensation forms underneath, which in turn promotes the development of rot.
