It is enough to correct one nuance related to the maintenance conditions, and the indoor hydrangea will come to life again.
Even a novice gardener can cope with the task. The peculiarity of this plant is that it reacts sharply to any negative change in the environment.
If the hydrangea leaves have started to turn black, you need to pay attention to one detail: whether they are dry or wet.
In the first case, we are talking about a simple sunburn. If they are raw, then the problem is different.
If there is a wet, wilted and blackening hydrangea on the window, it means that the plant is cold. These signs are the result of a draft or low room temperature.
Some gardeners mistakenly take these symptoms for a lack of moisture. They begin to water the plant abundantly, but only make things worse. The hydrangea begins to slowly rot and it comes to the point that all that remains is to throw away the dried-out trunk.
In addition, in this case, the possibility of a fungal disease in the flower cannot be ruled out. You need to carefully examine the hydrangea and try to transplant it into new soil and a pot as quickly as possible.
