What to do when orange tree leaves turn yellow? Latest solutions explained in detail
The orange tree is an economic crop, and it also has a certain ornamental value; for example, the kumquat is a citrus variety with a very beautiful tree shape. When we grow orange trees, abnormal yellowing of the leaves often appears, so what causes this phenomenon? When this phenomenon occurs, how should we solve it? Let us learn about it together below.
1. Causes of yellowing leaves on orange trees
There are many causes of yellowing leaves on orange trees. First, it may be caused by a lack of certain nutrients, such as a deficiency of nitrogen, iron, zinc, manganese, magnesium, etc. Second, it may be improper pest and disease control, with orange tree leaves suffering damage from pests and diseases, thereby causing the leaves of the orange tree to turn yellow. There is also the effect of weather on citrus trees: excessively high temperatures lead to too much water loss, and if water is not replenished in time, this can also cause leaves to turn yellow. Finally, there is unsuitable soil at the planting site, or changes in soil structure, which prevent the orange tree from growing normally, thus producing the phenomenon of yellowing leaves. Of course, there is also the possibility that the light is too strong and the leaves are burned by sunlight and turn yellow; this situation also exists.
2. Prevention and control methods
When orange tree leaves turn yellow, we need to solve the problem according to different situations. If it is a lack of some nutrient, then we only need to reasonably apply additional fertilizer to restore the tree's vigor and promptly supplement the missing nutrient, and the leaves will quickly turn green again. If it is the effect of pests and diseases, then it is enough to treat the different pests and diseases accordingly. As for the problem of water loss, we only need to water reasonably and maintain field humidity to avoid this phenomenon. Finally, if it is caused by soil problems, then improve the soil structure for the soil problem, such as adjusting pH, soil fertility, permeability, etc. There is also the problem of light, which is even easier to solve; just build a shade shed.
3. Precautions
During the process of growing orange trees, we generally only need to pay attention to these issues, and basically the phenomenon of yellowing leaves will not occur. First, we should apply additional fertilizer reasonably: apply base fertilizer heavily in winter, apply spring fertilizer early in spring, scientifically use nitrogen fertilizer, potassium fertilizer and phosphorus fertilizer during the flowering and fruiting period, and use them together with foliar fertilizer, and finally carry out reasonable foliar feeding. Second, reasonable water management: do not water too much, drain water in time, and keep the soil moist. There is also reasonable pruning of branches and leaves, intertillage and earthing up, etc. Finally, do a good job in the prevention and control of pests and diseases.
