Cultivation and Management techniques of Autumn Cherry Blossom
Autumn application of base fertilizer: generally apply base fertilizer in early September, when the fertilizer has sufficient time to mature, so that the tree can be absorbed and utilized before dormancy. At this time, the roots cut off by fertilization can more and more germinate and absorb a large number of roots, thus improving the absorption and utilization of fertilizer. The main types of fertilization are rotten farm manure, combined with a small amount of chemical fertilizer. In general, 50 to 75 kilograms of soil and miscellaneous fertilizer are applied to each young tree, and the basic fertilizer should not be too deep in autumn, and 40 to 50 centimeters is appropriate. The ditch application method can be used for young trees, and the sprinkling method can be used for strong trees.
