Matters needing attention in hydrangea cultivation

1, hydrangea likes acidic soil and is not tolerant to barren and saline-alkali soil. It grows poorly in alkaline soil, its branches and leaves are yellow, and it is suitable for loose, fertile and humus-rich acidic soil. Due to the influence of pH value, its color can change from white to red and from red to cyan.

2. In the annual growth period, topping can be done twice to promote branching. After flowering, leave the old branches in L ~ 2 nodes and cut them short to control the plant height and promote the growth of new branches. After autumn, cut off the top of new shoots to stop the growth of branches, so as to facilitate wintering.
