In order to keep the pot soil often acidic, it can be combined with adding 0.2% ferrous sulfate when applying liquid fertilizer to turn it into alum fertilizer for watering. Adding 0.5% superphosphate soaking solution for 1 to 2 times during the pregnancy bud period can promote the blooming and bright colors.

Hydrangea has larger leaves and requires more water. Water frequently in spring and summer to keep the pot soil moist; in the midsummer high temperature, water once in the morning and evening, and pay attention to proper shade; water less in winter, just keep the pot soil humidity; The pot soil is always kept in a moist state, especially in summer, and should be given sufficient moisture.

From May to August, in addition to meeting the water demand of the pot soil, water is sprayed on the leaf surface once a day.
