Ivy is absolutely hardy. Even the deepest frost over a longer period of time does not bother him. Only variegated varieties are not quite as frost resistant. It is therefore better to grow them in pots, as they are easier to overwinter that way.
Ivy does not need winter protection
You don't have to hibernate ivy in the garden
The normal ivy in the garden does not need any special protective measures in winter. Only with freshly planted ivy can it be worth protecting it from frost and, above all, from drying out with a layer of mulch in the first year.
Overwinter ivy in a pot
A special overwintering is not necessary for deeper tubs. If the ivy is cared for in the flower box, you should protect the soil from frost by placing the planters on an insulating surface and wrapping them with sacking if necessary.
tips
The biggest problem of ivy in winter is drought. If brown leaves appear in spring, this is rarely due to frost damage, but dried leaves. Therefore, in dry winters, water the ivy on frost-free days.
