The hydrangea is not blooming - there can be two reasons for this. The plant got frost or the hydrangea was pruned incorrectly.
If you have a hydrangea (hydrangea) in your garden, you may have noticed the following: The hydrangea forms the flower buds in autumn, next year blooms the hydrangea but not. The simple reason for this is that the buds froze in winter.
1. Protect from frost
You should protect the sensitive plant from temperatures that are too low. A frost protection fleece can be helpful here, or simply cover it with leaves. That's often enough.
2. Correct CutA second reason why hydrangeas don't flower could be wrong pruning. In principle, it is pruned in spring, but you have to be careful that you only cut off the old umbels.
If you also remove the new flowers, you will wait in vain for the flowers to bloom. If you want to stimulate the growth of the plant, remove about 25 percent of the old shoots, close to the ground. The flowering is a bit sparse, but the plant can gather strength for the next year and bloom all the more lavishly.
