Winter hardiness depends on the location
Almost all Macrophylla species, like that Farm hydrangea botanically correct, have a very good winter hardiness. Many old varieties of the farmer's hydrangea are still very popular today because they have proven themselves through their excellent winter hardiness. However, their specific resistance to frost and other adverse weather conditions mainly depends from their location away. These varieties are particularly necessary in regions where it gets very cold in winter good winter protection. The hardiest varieties include u. a. "Emile Mouillière", "Otaksa", "Lanarth White" and "Veitchii". Because of their inadequate winter hardiness, however, “Hanabi” and “Pink Elf” should better be cultivated in the tub.

Flower buds freeze to death in frost
The biggest problem with farmer hydrangeas isn't their actual winter hardiness, however - most varieties come off brilliantly the winter - but the fact that the flower buds formed in late summer of the previous year freeze to death can. As soon as this happens
the flowering fails in the following year. After all, farm hydrangeas only bloom on last year's wood and therefore do not develop any new flower buds in the current growing season. This problem can only be circumvented with appropriate winter protection or by planting new varieties that bloom on both old and new wood.New cultivars of the farm hydrangea particularly hardy
These new breeds including "Endless Summer" as well as the "Forever & Ever" series with four different flower colors are not only characterized by good winter hardiness. It is also not a problem if flower buds or previous year's shoots freeze to death, because new buds are formed on the young shoots.
Bring farm hydrangeas over the winter
In order to protect the wintering buds of the farmer's hydrangea from frost, good winter protection is necessary. However, this does not only happen through a cover (e.g. B. through a fleece or bast mats), but above all through the wise choice of location. In general, the sunnier the location, the more vulnerable the flower buds are to late frosts in spring. For this reason plant your farm hydrangeas if possible to a partially shaded or shady place without midday sun.
Tips & Tricks
In particular, the root neck is used for protection against the cold, e.g. B. by covering with bark mulch and / or leaves, grateful. This prevents the roots growing close to the ground from freezing through and thus dying off.
