What does vernalization of hydrangea mean?
Hydrangea blooms in winter, so it is necessary to prepare a pair of sharp scissors, then disinfect the scissors, and then prune the branches and leaves of hydrangea, so as to increase the ventilation and light transmission between plants and make hydrangea flourish. It is also necessary to cut off branches that grow too long to reduce the consumption of nutrients.
When maintaining hydrangea in winter, it is necessary to control the ambient temperature between 4- 10 degrees to avoid frostbite of plants, and at the same time, stop fertilization to avoid the harm of fertilizer to hydrangea. After the temperature rises and the weather gets warmer, fertilization can be carried out according to the growth state of hydrangea to increase its flowering.
