Reasons and Solutions for Yellowing Leaves on Orange Trees
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 occurs. So what causes this phenomenon? When it appears, how do we solve it? Let's learn about it together below.
1. Reasons for yellowing leaves on orange trees
There are many reasons for 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, thus causing the leaves to turn yellow. There is also the influence of weather on citrus trees: excessively high temperatures lead to excessive water loss, and if water is not supplemented in time, this can also cause leaves to turn yellow. Finally, there is unsuitable soil in the planting site, or changes in soil structure, which prevent the orange tree from growing normally, thus resulting in yellowing leaves. Of course, it is also possible 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 certain nutrients, then we only need to reasonably apply additional fertilizer to restore the tree's vigor and supplement the missing nutrients in time, and it will quickly turn green again. If it is the influence of pests and diseases, then it is necessary 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 light problem, which is even easier to solve: just build a shade shelter.
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 heavy base fertilizer 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 root-outside fertilization. Second, reasonable water management: do not overwater, drain promptly, 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.
