Yellow leaves as a damage image on the apple tree
When an apple tree shows signs of disease or other problems, it is often not easy for agr to pinpoint the cause. If the tree suddenly gets yellow leaves in spring or summer, there may be several reasons.
Fungus, mildew and scab
Among the most dreaded diseases of the apple tree are powdery mildew and apple scab. Both diseases are not actually a yellowing of the whole leaves, but the following symptoms:
However, yellow discolored leaves can also be caused by a fungal disease. This in turn is not only due to a lack of resistance of the respective apple variety, but often also to an insufficiently executed pruning.
The yellowing shortly after transplanting
If it comes to the yellowing of the leaves already shortly after planting or transplanting a young tree, this may also be the reason for the damage picture. For example, if the planting was done in the middle of summer or on a hot spring day, the roots of the apple tree may be too dry. The reason may also be a lack of water supply or too stony soil with less loose root substrate. For the planting of an apple tree, for these reasons, not only should an appropriately prepared planting hole of sufficient size and humus-rich substrate be available, but the time should ideally also be chosen in autumn after the leaves have fallen off.
Rodents and other pests
The yellow coloring of the leaves usually speaks in favor of a disturbance in the juice balance of the apple tree. This may also be due to damage to the roots by voles and other pests.
Tips & Tricks
Voles can not only be distributed by chemical means, mechanical traps and the electronic vole fright. A transplanting of the tree trunk with currant bushes protects naturally, as voles do not like their smell.
