The best choice for medium to large gardens - this rootstock will produce an apple tree about 4 metres (14 foot) wide at maturity. 

The roots are reasonably vigorous and an MM106 rootstock apple tree can easily support itself without the need for staking. It will produce about 23 kilo (50lb) fruit in a normal season. 

The tree will not grow too large, so that the average mobile person will find it easy to prune. It is normally too vigorous for cordons and espaliers, although on poor soil and with a less vigorous variety it may be a good combination.

GardenAction recommend the MM106 for the amateur gardener wanting a reasonable sized tree in medium to large gardens.
