- Fertility :
- Generally, apple trees are self-sterile. You need two apple trees of different varieties to ensure pollination. Apple trees are compatible within the same type. As all varieties of cultivated apple trees belong to the species Malus domestica, they can therefore pollinate each other. We advise you to have 2 apple trees in your yard, or to check if there are any nearby, if you want to be able to harvest apples.
