Farm hydrangeas should be protected in winter
Originally, the varieties designated today as farmer hydrangeas originate from Japan, where in many parts a similar climate prevails as in this country.
Hardiness depends on the location
Almost all Macrophylla species, as the farmer's hydrangea is botanically correct, have a fairly good winter hardiness. Many old varieties of the farmer's hydrangea are still very popular today, because they have proven themselves by an excellent winter hardiness. However, their specific resistance to frost and other adverse weather conditions mainly depends on their location. Especially in regions where it gets very cold in winter, these varieties require good winter protection. Among the hardest winter varieties include u. a. "Emile Mouillière", "Otaksa", "Lanarth White" and "Veitchii". Due to their poor winter hardiness better cultivated in the bucket, however, should "Hanabi" and "Pink Elf".
Flower buds freeze in frost
However, the biggest problem with farm hydrangeas is not their actual winter hardiness - most varieties are excellent over the winter - but the fact that the flower buds formed in the late summer of the previous year may freeze to death. As soon as this happens, the flowers will fail in the following year. Finally, potted hydrangeas only flower on the previous year's wood and therefore do not form new flower buds during the current growth period. This problem can be avoided only with a corresponding winter protection or with the planting of new, on both old and new wood flowering varieties.
New breeds of the farmer hydrangea particularly hardy
These new varieties, such as "Endless Summer" and the "Forever & Ever" series with four different flower colors, are characterized not only by a good winter hardiness. It also does not pose a problem when flower buds or previous shoots freeze because new buds are formed on the young shoots.
Farmer hydrangeas bring over the winter
To protect the overwintering buds of the farmer's hydrangea from the frost, a good winter protection is necessary. However, this does not happen only through a cover (eg by a fleece or bast mats), but above all by the wise choice of the location. In general, the sunnier the location, the more endangered are the flower buds due to late frosts in spring. For this reason, plant your farmer hydrangeas as close as possible to a partially shaded or shady spot without midday sun.
Tips & Tricks
In particular, the root neck is for a cold protection, z. B. by a cover with bark mulch and / or leaves, grateful. Such prevents the freezing and thus dying of near-ground waking roots.
