FAQs
Are these plants thornless?
Yes, the Triple Crown variety is specifically bred to be thornless, making them much easier to prune and pick.
What is the best time to prune these blackberries?
Prune back the canes that have fruited immediately after the harvest season to keep the plant healthy.
Do I need to plant both provided plants together?
You can plant them together for a larger harvest or separately in different parts of your garden as long as both locations receive sufficient sunlight.
Do I need a trellis?
While the plant has a semi-erect habit, it performs best when tied to a support structure like a wall or trellis to keep the fruit off the ground.
Are these plants hardy?
Yes, they are hardy and well-suited to most climates, though they appreciate a sheltered spot during extreme winters.
Troubleshooting
Slow growth after planting
Ensure the plant is receiving at least 6-8 hours of direct sunlight and that the soil is not waterlogged.
Berries are small or dry
Increase watering frequency during the fruit-set stage, as blackberries require consistent moisture to plump up.
Yellowing leaves
Check for excessive moisture in the root zone or potential nutrient deficiency; apply a balanced fertilizer during early spring.

Setup, Compatibility & Care
For the best results, plant your blackberries in a sunny spot with fertile, well-drained soil. If your soil is heavy clay, add organic matter to improve drainage before planting. Once established, regular watering during dry spells will ensure fruit development. Pruning is essential; once the fruiting canes have finished their summer harvest, cut them back to the base to encourage fresh growth for the following year. Ensure the plants are spaced at least 2-3 meters apart to allow for proper air circulation and to prevent disease.
