Water California Blackberry regularly, especially during establishment and dry periods. Aim for consistently moist, but not waterlogged, soil. Deep watering encourages strong root development.

Reduce watering slightly once established, but ensure adequate hydration during fruit production for optimal yield.

Prune California Blackberry annually, ideally in late winter or early spring before new growth starts. Remove old, dead, or unproductive canes.

Thin out dense growth to improve air circulation and sunlight penetration, which helps prevent disease and encourages better fruit production.

California Blackberry can be propagated through several methods. Tip layering is effective, where a long cane is bent down and covered with soil to root. Cuttings can also be taken from semi-hardwood in summer.

Division of established root clumps in dormancy is another reliable method.

Repotting is typically relevant for container-grown California Blackberry. Repot every 2-3 years in spring as growth begins. Choose a pot at least 5 cm larger in diameter.

Use a well-draining potting mix and ensure the plant is adequately watered after repotting.
