If you have a hydrangea (hydrangea) in the garden, you may have noticed the following: The hydrangea will start flowering in autumn and next year flourishes the hydrangea but Not, The simple reason is that the buds froze to death in winter.
1. Protect from frost
So you should protect the sensitive plant from too low temperatures. A frost protection fleece can be helpful here, or simply cover it with leaves. That is often enough.
2. Right cut
A second reason why hydrangeas don't bloom could be in the wrong cut. In principle it is cut in spring, but you have to be careful that you only cut off the old flower umbels.
Anyone who removes the new flowers, however, 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 near the ground. So the flowering is also somewhat sparse, but the plant can gather strength for the next year and bloom all the more abundantly.
