Rootstock Cherry Colt is used for the propagation of fruit trees through budding or grafting the desired scion onto the rootstock. Colt was developed at the East Malling Research Station in Kent and released in 1977. It is a cross between the sweet cherry Prunus avium and a related but less vigorous species Prunus pseudocerasus. It was the first dwarfing rootstock for sweet cherries, making it possible to grow a cherry tree in a small garden.
Colt produces a tree to around 4.5 m, and tolerates poorer soils. Colt is roughly comparable to the apple MM111 rootstock.
*Plant growth is always influenced by climate, nutrition, water availability, scion vigour, etc, so height figures are always only a guide.
