You should know that the apple tree does not like frost or hot weather. This is why it is usually grown in the fall.
It is important that its roots get stronger to withstand winter. You can nevertheless proceed to its culture in spring or summer. The main thing is to ensure that the temperatures are neither too low nor too high.
Prefer to choose a sunny or semi-shaded place to plant it. The apple tree particularly likes rich, consistent and well-drained soils.
