In the large family of hydrangeas, panicle hydrangeas are considered to be particularly hardy.

Panicle hydrangeas tolerate frosty temperatures
The hardy panicle hydrangeas withstand adverse temperatures and even ice and snow. If their shoots freeze down in winter, that's not really a problem, after all, the bushes will sprout again in spring. Nevertheless, it can be more difficult to drive out again once all above-ground parts have frozen away. For this reason, it is advisable to also provide the panicle hydrangea with winter protection. For this purpose you can very well use brushwood and fir or spruce branches and mulch the root area with bark mulch or similar.
Flowering is not endangered by frost
In contrast to the peasant hydrangea, the frost cannot harm a panicle hydrangea, after all it only blooms on the young, this year's shoots. In addition, the old wood is cut out in the spring anyway. It only becomes dangerous if the plant is encouraged to sprout very early by a very sunny location or mild temperatures and is finally surprised by late frosts - especially around the time of the ice saints in mid-May. In this case, the fresh shoots with the new flower buds freeze and the flower may fail. The resourceful gardener therefore provides appropriate protection when late frosts threaten.
Protect young specimens
Many young plants are very sensitive to frost, and panicle hydrangea is no exception. Therefore, very young specimens - for example in the first and maybe also in the second year - should preferably overwinter under cold house conditions and should never stay outdoors. If necessary, you should dig up the shrub again and keep it in a bucket.
Overwinter panicle hydrangeas properly in pots
Older specimens in larger tubs can usually overwinter outdoors without any problems, provided they are provided with protective mats. For this purpose, place them in a sheltered location, e.g. B. to a heat radiating house wall. However, if the planter is smaller than about 40 to 50 centimeters in diameter, the potted hydrangea should overwinter in the house, in the apartment or, if necessary, in the garage or basement. The environment should be frost-free, but cool and bright. However, a lack of brightness can be remedied with the help of a plant lamp (€21.99). Overwintering temperatures between 2 and 5 °C are ideal.
tips and tricks
Panicle hydrangeas need to be watered from time to time, even in winter, but fertilization is not necessary.
