1, most of the reasons why hydrangeas don't bloom wrongly are caused by people's pruning mistakes, because most of the hydrangeas we raise are opened by old branches, including the endless summer that everyone raises, and old branches can bloom with new buds. If he doesn't prune properly, even if the new buds grow and bloom, the flower heads will become smaller and the flowering period will be delayed, so pruning must be appropriate. Moreover, most of the hydrangeas raised by everyone are big-flowered varieties. It must be remembered that hydrangeas are old branches.
This old branch must be aged before it can sprout and blossom in the next year, so it must be trimmed well. Generally, after August, the hydrangeas in Panyu should not be trimmed. It is recommended that you prune it in time after flowering, and all the lateral buds that grow in the future will be preserved. Of course, this bud will not stop growing until the end of autumn. In the second year, it will come out from the top and bloom, so will the endless summer, and so will other varieties of hydrangea.
2. The indoor temperature is too high in winter. In winter, if the indoor temperature is always high and the rising trend is very rapid, its branches are always in the emerald green at the top, so it is not easy to bloom. So try to keep the temperature not too high in winter. Some people who love flowers immediately put them indoors, and the temperature is constantly above 20 degrees. It is not appropriate for them to grow all the time.
I suggest you put it near the window where the temperature is relatively low, or you can put it in Daoli District. Most hydrangeas are not prone to problems as long as the temperature is not lower than MINUS 10 degrees. Let it stop growing in a short time, at least for more than a month, and the branches will thicken and harden, then the top will sprout quickly.
3. It has been said that the temperature of hydrangea is not lower than-10 degrees before freezing, and most varieties are not easy to freeze to death. Under normal circumstances, if they are raised at home, many flower friends will choose to plant them in the ground. However, if the temperature of plants on the ground exceeds-10, they will see the top of branches freeze to death or twigs freeze to death, and they can germinate the next year.
However, after the germination stage, this kind of bud is thin and weak, and it is all branches without vernalization, so the probability of its flowering will be very small. So if the temperature there is too low, plant it in the garden and provide safety protection in winter, such as wearing a non-woven handbag or packaging bag.
4, lack of light Many people keep hydrangeas indoors. Hydrangea is a sunny green plant, which is more tolerant to shade, so don't put it in dark places, especially in autumn and spring. Without light, the branches in autumn will look very thin, will not age, and will not bloom easily the next year. In spring, the branches are old, but if you put them in the shade of the room, they won't bloom.
Therefore, it is recommended that you ensure sufficient sunshine in spring, autumn and winter, and moderately shade 30%-50% in hot weather, so that problems are not easy to occur. With sufficient light, the branches will age quickly, and with sufficient light in spring, the buds will grow quickly, and the flowers with buds will have a headache. These are the four key points that cause hydrangea not to bloom when we raise hydrangea. It must be effectively avoided during normal maintenance to ensure that there is no problem. Most people who love flowers are mainly caused by improper pruning, so please see where you belong and correct it in time.
