September Ruby is a very cold hardy tree developed for the Prairie Fruit Breeding Cooperative. It is a vigorous grower that is resistant to fire blight and is popular among orchards for its annual production. Its apples are very good for eating and cooking. This tree blooms in mid May for an attractive ornamental.

Note: We do not ship grafted apples to BC due to regulatory restrictions from the Canadian Food Inspection Agency.

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.
