The best climate for growing apples depends on the type of apple. Not all apple trees have the same tolerance profile. Apple trees also need direct summer sun regardless of the type or climate.
Spring is the best time to plant apple trees in most northern and centrally located areas. Southern areas, or places where the fall and winter weather is more mild, allow for fall planting. Apple trees need well-drained soil and should be planted on a north or east-facing slope for best sun exposure. In colder climates, apple trees should not be planted in frost pockets or where cold air settles.
