Big Daddy Thornless Blackberry is a vigorous, thornless cultivar that produces deep purple, glossy berries renowned for their sweetness and rich flavor. Growing 60 to 72 inches tall with a dense, productive habit, this variety thrives in full sun with moderate water and well-drained soil. The thornless canes make harvesting a genuine pleasure, and the fruit's high antioxidant content, bioflavonoids, and vitamin C make it as nutritious as it is delicious. Once berries ripen to full black, they're ready to harvest and should be picked every few days at peak ripeness.

Plant Big Daddy Thornless Blackberry in well-drained soil in a location with full sun exposure. Allow bare-root plants several days to acclimate gradually to their new site before planting. Space plants 3 inches apart. Plant in early spring as soon as soil is workable.
Harvest only berries that are fully black; underripe berries will not continue ripening once picked. Look for berries that are plump yet still firm, and they should pull easily from the cane with a gentle tug. Harvest frequently, every few days once ripening begins, and keep the center plug within the berry intact during picking, unlike raspberries. Pick in the morning or once the heat of the day has passed, and refrigerate immediately after harvest to preserve quality.
