1、 Remove the blade

Generally speaking, it's best to insert the watered branches after flowering in combination with the pruned branches, so that the utilization rate of the branches is high. Hydrangea inserted in water must have an ideal environment. The branches inserted in water cannot carry any leaves, that is, there can be no leaves below the water surface. All the leaves at the underwater position should be removed, otherwise they are easy to rot

2、 Rooting agent soaking

When Hydrangea is hydroponically cultured, the branches are soaked with rooting agent in the water or before water insertion, which stimulates the formation of healing tissue and is more conducive to rooting

3、 Breed in a dark environment

During hydroponic culture, the growth of roots needs a dark environment, and the water part of branches should be placed in a dark environment, so as to be more conducive to the growth of roots. If the light is too strong, it will inhibit the growth of new roots. Hydrangea that has just been watered is not recommended to be placed in areas with too bright light or too strong wind, which will cause dehydration and wilting of leaves and even rot of branches, resulting in failure of watered insertion
