Why grow blackberries when they grow wild?

The domesticated varieties we offer have delicious differences in flavor, are productive and we have six varieties without thorns! We offer well rooted 1 year vines. Some blackberries cannot be shipped to CA or HI, see individual varieties for details.

Useful Facts

Pollination: Self-pollinating, except for Cascade Trailing.

Hardiness: A way to make all varieties much hardier is to lay the canes on the ground and cover them in late fall with soil, snow or a thick mulch. Uncover them in the early spring. Hardiness depends on the variety but even the most hardy cultivars Chester and Triple Crown, Loch Ness and Tayberry are only hardy to Zone 5.  Most others are hardy to USDA Zone 7.

Harvest time: Varies from June through October. See ripening order at the bottom of the page.

Method of propagation: Cuttings, tip layering.

Life expectancy: 6 to 25 years depending on variety and care.

Bearing age: 2 years and every year thereafter. Prime Jim, Prime Jan and Prime Ark 45 bear the first year.

Yield: 10-20 pounds per plant.

Plant spacing: Each variety differs in vigor. Between plants; Triple Crown 8; Marion types, Cascade Trailing, Logan and Black Pearl, Black Diamond and most others 7 feet, Loch Ness, 6 feet, Boysen 5', Tayberry and Prime Ark  4 feet, Arapaho, Apache, Chickasaw, 2 to 4 feet.

Exposure: Sun or partial shade.

Soil requirements: Wide range of soils. Will tolerate some poor drainage. Will do best in soils with abundant organic matter.

Pests and diseases: None

Cultural requirements: Except for Prime Ark, Prune out all canes in the autumn after they bear fruit. Blackberries bear on last years growth. Train on wires or fences, except the free standing Arapaho, Loch Ness or Apache. Prune Prime Ark can be pruned to the ground each fall after bearing like a primo cane raspberry.

Training: Keep the canes off the ground to make care easier. Keep the new and two year old bearing vines separate so you can prune off and remove them after they bear. See owner’s manual that comes with each order or click here to see it on line.

Using blackberries

In the landscape: Use as a barrier hedge; trellised on a fence.

In the kitchen: Make cobblers, pancakes, pies, mousses, sauces and, of course, jams and jellies.

For Your Health: Many varieties of blackberries have more anthocyanins
than blueberries. They are also high in fiber.
Wild Treasure, Chester, Logan, Boysen and Marionberries are among those rated highest in nutritive values.
