Observations, suspicions, history |
MM.111 is appropriate for use with spur type scion varieties, on poor dry sandy soils, and on heavy soils where MM.106 would fail. Because MM.111 produces large trees, utility of MM.111 in North America is limited to extreme situations and home gardens. MM.111 is very tolerant of a wide range of soil conditions, and is the most drought tolerant clonally produced apple rootstock. |
