The McIntosh Apple Tree is a highly cold-hardy (Zones 3-7) deciduous fruit tree, prized for its classic red-skinned, white-fleshed, tart, and aromatic apples that ripen in mid-September. Originating in Canada, these productive trees (12–20 ft tall) require full sun, well-drained soil, and a pollinator like Gala or Fuji. They are perfect for fresh eating, baking, and cooking.
