The most suitable time for Hydrangea is spring. At this time, the growth ability of the plant is relatively good. After changing the basin, it will adapt to the new environment quickly, and the damage to the plant will not be too great, because it is not easy to be affected by the environment at this time. In addition, do not change basin too often, usually breeding 1 - 2 years to give it a basin to change.
1. With soil: it is better to take some original soil when changing basin, because it is easy to damage the root system if all the soil is removed. Moreover, with part of the original soil, it will also be more conducive to plant adaptation to the new basin soil.
