In autumn, Nanking cherry blossom needs to pay attention to disease prevention and leaf preservation. Because the leaves of Nanking cherry blossom are easy to be attacked by diseases, if they are not controlled in time, they will lose their leaves, and the nutrients will not be accumulated, which is very harmful to the next year's flowering, so we must pay attention to prevention and control in autumn.

In autumn, Nanking cherry blossom needs to apply enough base fertilizer, generally in the first ten days of September.

Generally, the fertilizer is moderate when fertilizing, but be careful not to bury too deep.
