Apples

M25 – Very vigorous. Up to 5m high.

Grow as full or half standard. Ideal in poorer soil in exposed sites. Space trees 7-10m apart.

MM111 – Vigorous. Up to 4m high.

Grow as standard or half standard. Tolerates wet ground and has good disease resistance. Space trees 6-10m apart.

MM106 – Semi vigorous. Up to 4m high.

Good for half standards, espaliers, cordons. Space half standards 3-6m apart.

M116 – Medium. Up to 3m high.

10% less vigour than MM106. Space trees 3-6m apart.

M26 – Semi dwarf. Up to 3m high.

Requires staking. Used for bush trees and cordons. Space bush trees 2-4m apart.

M9 – Dwarf. Up to 2.5m high.

Needs permanent staking. Makes good bush and cordons. Space bushes 2m apart.

M111/M9 – Dwarf. Up to 2.5m high.

A combination of a vigorous rootstock and a dwarfing rootstock.

Doesn’t need permanent staking.
It produces a tree with a strong root system that is suited to poorer and wetter soils than any other rootstock, yet still allows for a small tree.
This combination of MM111 with an M9 interstem is ideal for more marginal growing areas where a small tree is required.
Due to the extra work involved, these trees sell for £24. Pre ordering a season or two beforehand is recommended.
