Hydrangeas not only do well in beds, but also in tubs. However, there are a few things to consider when hibernating.
With their flowering 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 potted plant in winter. There is a huge selection of different varieties on the market, so it is always best to choose one that is hardy.
Insensitive to low temperatures and frost are, for example, farmer's hydrangea, forest hydrangea, garden hydrangea, climbing hydrangea, plate hydrangea, pot hydrangea, Japanese hydrangea and especially panicle hydrangea. In general, these are also the varieties that you can easily outshine. Varieties that need a lot of sun, on the other hand, will also give you more problems in winter.
Overwintering tub hydrangeas - you should pay attention to this
» Stop fertilizing from autumn:
To ensure that the hydrangea in the tub survives the winter unscathed, there are a number of things you can do in autumn to prepare them for the lower temperatures. So you shouldn't fertilize the hydrangeas in autumn for the time being, because that can lead to considerable damage. This gives the plant more energy and would start sprouting again at the first milder temperatures. When temperatures drop below zero again, it is usually not just the fresh shoots that freeze, but often the older parts of the plant as well.
» Remove dried plant parts:
You should also remove protruding and dried-up parts of the plant in autumn so that the plant does not suffer so much from possible snow loads. However, you should avoid a radical pruning in autumn.
If some shoots freeze in winter, you can simply cut them off in spring.
» Water correctly:
The hydrangea does not like drought and waterlogging. Proper watering is important, especially before winter. You then have to water your tub hydrangeas depending on the weather. If they don't get any rain, you'll need to water them more frequently.
»Bucket Size:
The size of the pot is important for wintering outdoors. This should have a diameter of at least 30 to 40 centimeters. If the planter is smaller, you must look for winter quarters where 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 usually not affected by frost, you should protect the hydrangeas with some brushwood, fleece or a jute sack in severe cold.
