A cross between Northern Spy x M.1 that tends to be more sensitive to soil moisture levels than many rootstocks especially if the soils are poorly aerated. On dry sandy soils MM.106 will produce a tree of smaller size than M.7. On more fertile soils MM.106 will produce a tree of similar height to MM.111. MM.106 does not sucker and is resistant to Wooly Aphids, producing trees with moderate vigour and heavy cropping potential.
Trees on MM.106 are reported to be resistant to potassium deficiency, but can occasionally suffer from magnesium deficiency. Trees on MM.106 adapt well to a wide range of soil types and climatic conditions, making it a very popular rootstock world wide.
Our retail range of rootstocks have been grown for an extra year inground to produce a large plant suitable for a variety of grafting techniques.
*Plant growth is always influenced by climate, nutrition, water availability, etc, so height figures are always only a guide.
