Do hardy hydrangeas need additional winter protection?
Almost all hydrangeas offered in our latitudes are hardy and need only mild protection in mild regions. Even with locations where lower temperatures are lower over a longer period of time, the hydrangea usually copes well. However, you should take appropriate measures here to protect the plant from frost.
The winter hardiness is also dependent on the variety
How much frost a hydrangea tolerates is usually noted on the plant label, because not all hydrangea varieties are coping well with the longer frost periods of our climate zone equally well. Farmerships that are relatively hardy and robust are relatively freezing, even in harsh areas and with a little winter protection. Panicle hydrangeas tolerate frosty temperatures well.
Winter protection makes sense
Also hardy hydrangeas need a light winter protection. The following measures have proven successful:
Please never use plastic wrap to protect the hardy hydrangea from the cold. Also bubble wrap is unsuitable. Moisture accumulates under these impermeable materials. These are optimal conditions for mold and other fungi that can cause massive damage to the plant.
Winter hardy hydrangeas in the tub overwinter
Hydrangeas, whose pots have less than thirty centimeters in diameter, should preferably be overwintered in the house. Well suited is a room in which also during the day a temperature of about ten degrees prevails. Ventilate regularly, because too high air humidity threatens the risk of fungal diseases.
Container horticultural hibernate in the field
With our tips, you can maintain hardy hydrangeas on the balcony or terrace even during the cold season:
Tips
Hardy hydrangeas usually do not freeze to death - but can dry up. Therefore, it is important to water the plants moderately but regularly in winter, especially when the days are a bit warmer and free of precipitation.
