Yes, and it is actually a smart approach for Santa Cruz gardeners who want berries without the aggressive spreading that blackberries are known for. A large container keeps them contained and productive.
Blackberries need a pot that is at least 15 to 20 gallons with good drainage holes. Use a quality potting mix (not garden soil, which compacts in containers) and choose a compact or thornless variety bred for container growing. Baby Cakes, a thornless primocane-fruiting dwarf, does well in pots and produces fruit on first-year canes. UC IPM's caneberry production guidelines note that consistent moisture is critical for container berries, since pots dry out faster than ground soil, especially during our warm inland days in the Pajaro Valley or Scotts Valley.
Place your pot where it gets at least 6 hours of direct sun. In foggier parts of Santa Cruz (the Westside, Aptos near the coast), a south-facing spot against a wall helps concentrate warmth and light. Even in the fog belt, blackberries produce reasonably well because they tolerate cooler conditions better than many fruiting plants.
The main challenge with container blackberries is watering. During summer, you may need to water daily. Drip irrigation on a timer solves this if you set it up early in the season. Feed with a balanced berry fertilizer in spring and again after the first flush of fruit. In winter, the canes will go dormant. Prune out any canes that fruited (they will not produce again), and leave new canes for next year's crop.
This week: If you want container blackberries this season, order a Baby Cakes or Prime-Ark Freedom plant now and pick up a 15-to-20-gallon pot with drainage holes.

Frequently Asked Questions
How big does the container need to be for a potted blackberry?
Use a pot of at least 15 to 20 gallons with good drainage holes, and fill it with quality potting mix rather than garden soil, which compacts in containers. The larger volume holds moisture longer and gives the roots room to establish.
Will blackberries still produce in foggy coastal Santa Cruz?
Yes. Blackberries tolerate cooler, foggier conditions better than many fruiting plants, so they remain viable across the region. In foggier spots, placing the pot against a south-facing wall helps capture extra warmth and light.
How do I prune a potted blackberry through the year?
Remove canes once they have fruited, since they will not produce again, and keep the new canes for next season. Canes go dormant over winter, then resume growth in spring.
