Fruit tree height estimator

The mature height and size of a fruit tree is determined mainly by the rootstock. However the natural vigour of the chosen variety (the scion vigour), the quality of the soil, and the local climate all have a significant effect. The fruit tree height estimator on this page uses a formula to relate all these factors - not just the rootstock - to predict the mature height of your fruit tree.
