They themselves will be pollinated from others within their own or a neighbouring group. For example, the usual equivalent of 1 is A, 2 is B etc.Ĭultivars with three sets of chromosomes - triploids (marked T) - are ineffective as pollinating partners. Other sources or suppliers may use letters. For example, apple will only pollinate apple, pear pollinate pear, but plums, gages will damsons will pollinate each other if compatible.įor cross pollination choose a cultivar from within the same pollination group (flowering period) or from the adjoining groups, where flowering periods overlap. The RHS uses numbers to distinguish between individual pollination groups. a different cultivar of the same kind of fruit. Most apples, pears and some cherries, plums and gages are not self-fertile but need a pollinator, i.e. If smaller trees are wanted, buy cultivars grafted onto very dwarfing, dwarfing or semi-dwarfing rootstocks. The rootstock can also contribute to the disease resisting abilities of the plant. It is the rootstock that largely controls the size and vigour of the tree. Most tree fruit cultivars are grafted or budded onto rootstocks. Where possible, preferably buy from suppliers with Plant Health Propagation Scheme (PHPS) certification. Healthy plantsĪlways aim to obtain healthy plants from a reputable source. ![]() The following represents only a brief guidance on what to consider and a small selection of fruit tree cultivars well suited for the garden.
