Shallow planted trees of ‘Delicious’ apple (Malus domestica Borkh.) on Malling 7A (M 7A) and Malling-Merton 111 (MM 111) rootstock were smaller in the 5th year following planting and had higher bloom densities than deep-planted trees. Trees on MM 111 also had more fruit per cross sectional area when shallow planted. Deep planted trees of MM 111 had greater depth to the first root. No differences were observed in degree of lean of either rootstock.
