1、 Soil

The cultivation of Hydrangea requires that the soil must be loose, water retaining, permeable, fertile and moderately slightly acidic, so as to be conducive to growth

2、 Moisture

Hydrangea has high requirements for moisture, and the humidity of the surrounding air is required to be relatively high. Because its leaf evaporation is large, if the humidity is low, the flower can not ensure normal growth

3、 Light

The maintenance of Hydrangea requires bright scattered light. It is best not to maintain it in a full light environment, nor in a completely shaded environment. It can maintain its normal growth by ensuring 3 to 6 hours of light every day

4、 Temperature

Hydrangea does not have high requirements for temperature. It can overwinter on land normally in many places in China. It is most appropriate to keep the temperature between 18 and 28 degrees. It should not be lower than 5 degrees in winter. About 20 degrees can promote flowering

5、 Pruning

The maintenance of Hydrangea should pay special attention to the pruning time. Generally, there are two common varieties in the market: big flower Hydrangea and endless summer. The flower buds of endless summer can differentiate many times, so the pruning time is not very sensitive. However, the large Hydrangea must be pruned in the first and middle of August, followed by the time of flower bud differentiation. If the pruning lags behind the defoliation, the flower buds are actually cut off, which will reduce the number of flowers in the later stage
