Product Description:

Rubus 'Olallie' Oregon has produced some amazing soft fruits, and the Olallieberry is one of the greatest. Developed from a cross of Loganberry and Youngberry, this blackberry look-alike offers a sweet-tart burst of flavor from tender, juicy berries. Enjoy them fresh or processed into baked goods, smoothies, jams, syrups, and any number of treats. Olallieberries ripen early with medium-sized, oblong fruit in deep, purple black. The thorny vines are vigorous and long, so they’re best trellised. Its name comes from the Chinook word for ‘berry’, and it’s part of the parentage of Marionberry.

Olallieberries are 1 year old and ship late March in 3 ½ inch pots. Order early for best availability. Detailed planting information and growing instructions are included with each order and may be obtained below. Available only in the contiguous US.

Initial Instructions
After unpacking, allow the plant a few days to gradually acclimate to its full exposure. Plant your Olallieberry in an area with well-drained, not soggy soil that’s enriched with humus. Initially, apply ½ cup of Territorial’s Complete Fertilizer per plant mixed into the bottom of the planting hole, backfill around the plant and water well. Olallieberry plants appreciate a minimum of ½ day of sun to full sun for best production.

In years to follow, apply ¼ pound of Territorial’s Complete Fertilizer per plant in the spring (before growth starts) and again in May. Maintain good weed control. If using mechanical weed control do not work soil very deep as Olallieberry roots are shallow.

Olallieberries are generally vigorous growers and require support to hold up the plants. A trellis or fence at least 4-5 feet tall should provide adequate support. Olallieberries produce fruit on the 2nd year old canes. After fruiting, the cane will die, and you can prune it back to the ground. In spring, prune the canes to about 5 feet tall to encourage lateral branching and produce more fruit. Keep the soil moist for the first year to establish the plant.
