Balsors Blackberry
Red Mammoth Raspberry

The Balsors Blackberry is a cold-hardy variety that produces very large, sweet and juicy blackberries late in the summer. They are great for baking and fresh eating.

Balsors Blackberry are floricanes, primarily fruiting on second year canes. Each spring cut back all two-year old canes, leaving only the last year’s growth. This is a self-pollinating variety, so it doesn’t require a second plant nearby to set fruit.

Developed by the University of Saskatchewan Fruit Program, SK. Red Mammoth was a high yielding and firm variety released in 1999. It produces distinctively large bright red berries about 1 inch wide. It is also more cold hardy than older raspberry cultivars. Red Mammoth is firm which makes it suitable for commercial production and sweeter than Boyne. Floricane.

Needs to be trellised as canes are not as sturdy as other varieties.
