Hydrangeas not only look good in beds, but also in pots. However, with hydrangeas, which are kept as container plants, there are a few things to consider when wintering.Purple hydrangea as a container plant
With their flower-studded umbels, hydrangeas not only beautify flower beds, they also look wonderful planted in a bucket on the terrace or balcony. The only question is what should happen to the tub plant in winter. There is a huge selection of different varieties on the market, so it is best to always choose one that is hardy.
For example, farm hydrangeas, forest hydrangeas, garden hydrangeas, climbing hydrangeas, plate hydrangeas, pot hydrangeas, Japanese hydrangeas and above all panicle hydrangeas are insensitive to low temperatures and frost. These are generally the varieties that you can easily outshine. Varieties that need a lot of sun, on the other hand, are more likely to cause problems in winter.
Overwintering potted hydrangeas - you should note that
➤ Stop fertilizing from autumn:
So that the hydrangea in the bucket survives the winter unscathed, you can do a lot in autumn to prepare it for the lower temperatures. So you should not fertilize the hydrangeas in autumn anymore, because this can lead to considerable damage. This gives the plant more energy and would start to sprout again at the first milder temperatures. Then come back below freezing, mostly freezing not only the fresh shoots, but often also the older parts of the plant.
➤ Remove dried up plant parts:
In addition, you should remove protruding and dried plant parts in autumn so that the plant does not suffer as much from any snow load. However, you should avoid a radical cut back in autumn.
If some shoots freeze in winter, you can simply cut them off in spring.
➤ pour properly:
Hydrangeas don't like dryness and waterlogging. Correct irrigation is particularly important before winter. Depending on the weather, you will need to water your tub hydrangeas. If they don't get rain, you need to water them more often.
➤ Bucket size:
The size of the bucket is important for wintering outdoors. This should have a diameter of at least 30 to 40 centimeters. If the planter is smaller, you need to find a winter quarters in which the temperature is 3 to 5 degrees.
➤ Select a sheltered location:
It is important that the hydrangeas are in a sheltered place in winter.
➤ Protect plants with brushwood, fleece or a jute sack:
Although the hardy varieties are normally not affected by frost, you should protect the hydrangeas with some brushwood, fleece or a burlap bag in severe cold.
