| Rootstocks | Pollination for successful fruiting | |
| Fruit trees are grown on rootstocks which determine vigour and eventual size. Each type has different characteristics. | Pollination Groups (GRP): Apple trees require a pollination partner growing nearby, either a fruiting or an ornamental apple tree, that flowers at a similar time. A few varieties are Triploid(T) and require two pollination partners. These are indicated in the table.The flowering period, which ranges from A (early) to E (late), is given in the apple varieties table. A variety can be pollinated by another of the same flowering period or one to either side.
Explanation of Terms Bush – two year trees topped at 75cm to produce a head of branches. Container – tree in a ten-litre pot topped at 75cm to produce a bush tree. |
