For an apple tree to bear well, the self-sterile tree needs a suitable pollen donor. In this article we will clarify at what distance the two trees can stand from each other so that they are rich.
How far away should the pollinator be from the apple tree?
For high yields, it is recommended that asuitable pollinatoris located at a distance offifty to one hundred meters from the apple tree. It is also important that it is a suitable variety as a pollen donor.
How big can the distance between the apple tree and the pollinator be?
For a rich fruit yield, it is recommended that the two treesbe no more than fifty to one hundred meters apart. However, the pollinating insects fly up to a kilometer in search of food, so that even a distant apple tree can serve as a pollen donor.
As a rule, there are enough cross-pollinators in the immediate vicinity of home gardens. A he althy mix of varieties makes sense here too. Therefore, before planting an apple tree, coordinate the variant with your neighbors.
Why does the apple tree need a pollinator?
Apple trees areself-sterile cross-pollinators. Since its own pollen does not germinate sufficiently on the stigma, the apple tree cannot pollinate itself. In addition, not every variety is an equally good pollen donor for another.
A special feature of apples are the triploid varieties, such as Gravensteiner. If you cultivate these, there should be two diploid varieties nearby so that they can fertilize each other with foreign pollen.
Which apple trees cross-pollinate?
Thepollinator varieties must bloom at the same timeBut even if this is the case, it is not guaranteed that a particular apple tree is suitable as a pollen donor. For this reason, there are long lists in which it is noted which apple varieties are particularly beneficial for cross-fertilization. Crabapple varieties are also often used. These bloom profusely, produce lots of nectar and do not need to be cut. They are planted at a suitable distance from the apple trees and, like any other apple variety, ensure good fruit set.
Tip
Pollinator insects need food all year round
So that fruit trees bear plenty of fruit, it is important to provide an attractive environment for honey and wild bees as well as bumblebees and hoverflies. In addition to the blossoms of the fruit trees, the hard-working helpers need an early and night harvest in order to always find enough food. Also ensure that you have suitable shelter options.
