Unlike the potted plant, the hydrangea in the bed is relatively hardy, but under certain conditions. First, it depends on the species, because some are less frost resistant, others more. This is due in part to the increasing interest in raising hydrangeas as container plants. As a result, winter hardiness is no longer a priority for growers. This is especially true of some plate and farmers’ hydrangeas, while climbing hydrangeas, panicle hydrangeas, woodland hydrangeas, garden hydrangeas and Japanese hydrangeas can withstand frost particularly well.

Tip: Shade-loving varieties are hardier, while those that prefer full sun as a location are more sensitive to cold.

On the other hand, the region or the winter itself also plays a role. If this is particularly cold (with nights below minus 20 degrees), then the plant needs a little support to get through the cold season.

Some varieties of hydrangea are better protected from frost and more winter hardy

Last but not least, age is also crucial. The younger your garden hydrangea is, the more it will also need extra protection. If you have even just planted them fresh, even more so!

Hydrangea wintering in the garden – prepare the garden hydrangea.

Before you start winter protection, it is important to prepare the garden hydrangea. Only in this way hydrangeas can overwinter in the garden without suffering any damage:

  • Some varieties still bloom even in the fall, and as long as this blooming continues, you do not need to worry about winter protection yet. As soon as they have wilted, cut them back.
  • Cut off any parts of the plant that have withered.
  • Also, rake up any fallen leaves regularly to prevent fungal growth from the high humidity in the fall.
  • Normally, all leaves should have fallen from the shrub by winter. However, if fall suddenly turns to winter instead of gradually, you may need to do some remedial work by plucking them off.
  • Continue not to let the soil dry out, but keep them moist until the first frost.
  • Stop fertilizing in the fall, as this would encourage growth, and anything that sprouts new in the fall may freeze in the winter. And in this case, usually the older parts of the plant also carry damage.

  • Protect the shoots if you cut your hydrangeas in the fall . Because if the plant sprouts now, it is particularly sensitive parts of the plant, which would most likely be harmed by frost. For small shrubs, it is easy to put burlap or a plant fleece over the plants at night.

Note: Even very large shrubs are difficult or impossible to cover with linen. Therefore, it is more advisable to wait until spring before pruning.
