The growth, but also the flowering and fruit production of an apple tree are influenced by different factors. If the fruit tree does not thrive as desired, there can be various reasons for this, which we would like to go into in more detail in this article.
Why doesn't the apple tree grow?
Incorrect orpoor nutrient supply, insect infestation, tree diseases and drought often lead to the apple tree not growing. Newly planted trees were sometimes simply planted too deep. Excessively compacted substrate or waterlogging can also be to blame for poor growth.
Why is the planting depth so important so that the apple grows well?
If the root collar is not slightly above the ground,the trunk will begin to rot. The bark protects the tree even in extreme weather conditions. However, if it comes into constant contact with moisture, the bark softens and the wood becomes sick.
Always plant an apple tree so that the thick grafting area is about ten centimeters above ground level. Trees that are planted too deep and barely grow can be dug up again in the first few years and replanted.
Why does compacted soil harm the apple tree?
In compacted substrates theproportionofcavitiesis verylowand the pores of the soil are extremely small. Watercan bepoorly stored and there is little oxygen available in the soil.
This is not good for the roots of the apple tree, especially since waterlogging often forms in these substrates, which leads to root rot.
So loosen the heavily compacted soil before planting with
- Sand,
- mineral sediments (silt) or
- Compost
up. In addition, you should incorporate soil activator (€36.00 on Amazon) to promote soil organisms.
What nutrients does the apple tree need for good growth?
A lack of the nutrientspotassium, iron or zinc causes the apple tree to grow poorly. Too much fertilizer is also harmful to it.
You can prevent this as follows:
- It is recommended to have a soil analysis carried out before fertilization.
- This means you know exactly which nutrients are missing or in excess.
- This way you can specifically eliminate any shortage or excess.
Why does drought affect apple growth?
Since thestorage organsof the apple tree do not reach the deeper,water-bearing soil layers anymorein dry conditions,the leaves hang tiredly on the branches, begin to change color and dry out. The fruits are rejected and height growth stagnates.
Always water the fruit tree thoroughly if there is no rain. A fully covered fruit tree requires a lot of water and should be watered every few days in the evening hours for about 30 to 45 minutes with a gentle stream, directly in the root area.
How do pests or diseases affect growth?
Diseases and pestsaffecttheleaves, fruits, bark, rootsand even thewoodof the apple tree. For the vitality of the tree and good growth, it is therefore important that you check it regularly for signs of disease and insect infestation.
Severe damage can usually be avoided through targeted control. Rely on biological measures that protect beneficial insects and thereby ensure an ecological balance in your garden.
Tip
Stimulating growth through pruning
Regular pruning encourages the apple tree to produce new shoots and produce lush leaves and lots of flowers. In particular, you can rejuvenate old fruit trees that no longer want to grow well and only produce sparse fruit in this way and promote growth.
