Harcourt Apple vs Ottawa 3 Rootstock

The Harcourt apple is a cold hardy apple produced by the University of Alberta. The fruit is good for fresh eating or baking, and ripens in late August.

Ottawa 3 Rootstock is the most dwarfing rootstock to come out of the cold-hardy breeding program by the Agricultural Canada Research Station in Ottawa. It produces dwarf to semi-dwarf trees that are 45-55% of standard size. Due to its superior hardiness, it is well adapted to Canadian weather conditions.

It originates from Malling 9 (M.9) and the Robin Crab and is considered more dwarfing than Malling 26 (M.26) and more vigorous than Malling 9. Ottawa 3 Rootstock is very productive and bears fruit early, often requiring structural support when young.
