It is generally believed that the yellow leaves of fruit trees are caused by lack of fertilizer. The main fertilizers that are lacking are nitrogen fertilizer, magnesium fertilizer and iron fertilizer. However, when there is no shortage of fertilizer, the leaves sometimes yellow. There are several reasons for the yellow leaf phenomenon:
1 Soil viscosity tends to cause yellow leaves, excessive watering or excessive rain can cause yellow leaves. 2 yellow leaves caused by frost damage, common in winter cold grapes not buried in the grapes often occur, resulting in late spring sprouting, yellow leaves. 3 Yellow leaves caused by excessive ringing, ringing should be based on the strength of the tree. 4 The application of unripe organic fertilizer resulted in yellow leaves. 5 herbicide damage caused by yellow leaves.
