Apple trees can be found in many gardens. Now, one might assume that it doesn't matter which variety of apple you plant. The apples certainly grow equally well everywhere. But that is far from the case. There are big regional differences.
Differences between north and south
Apples like it sunny on the one hand, but also humid on the other. One variety wants more sun, the other more rain. And so the whole thing can be well graded and divided. Which means that apple trees that grow and thrive in the south and give the gardener a bounty of harvest, are far from bearing in the north what the south benefits from.
Get advice from the gardener
So it is also clear that you shouldn't plant every apple tree in every part of the country if you want a bountiful harvest. Therefore, ask your gardener which trees are most suitable for your climate. If you pay attention to this, you will never have problems with the apple harvest again.
