Fruit Tree Rootstocks Explained

The final size of a fruit tree is dependant on several factors:

• Selected rootstock, the vigor of a fruit tree is mainly determined by the rootstock onto which it is grafted. The dwarf rootstocks have weaker root systems than the vigorous rootstocks, use more dwarfing rootstocks if you want smaller trees and/or are training into particular forms, (see table below).
• Vigor of the particular variety chosen, e.g. Apple Charles Ross is always less vigorous than Apple Laxtons Superb when grown on the same rootstock.
• Soil conditions. Fruit trees will not do well on poor, shallow soils.
• Geography, where you are in the country, latitude and altitude. Fruit trees grown in northern exposed areas on poor soils will always be less vigorous than those grown in more favourable areas.
• Pruning regime/training method. In a set time, trees pruned or trained will not reach the same size as those free growing.

Choose your rootstock with your chosen varieties, training method and your location in mind.
