Water regularly, especially during dry periods and fruit development, to ensure consistent moisture. Aim for about 2. 5 cm of water per week, either from rainfall or irrigation.

Established plants show some drought tolerance but perform best with adequate water. Avoid waterlogging, which can lead to root rot.

Prune annually in late winter or early spring to remove dead, damaged, or weak canes. Thin out older canes that have already fruited, as blackberries typically fruit on second-year wood.

This encourages new growth and improves air circulation, reducing disease risk.

Propagate easily from tip layering, where a cane tip is buried in the soil to root, or from root cuttings. Softwood cuttings can also be taken in summer.

Seeds require stratification but are less common for propagation due to variability.

Not typically grown in pots due to its vigorous, spreading nature. If grown in a very large container, repotting would involve refreshing the soil every few years or root pruning to manage size.

This is rarely necessary for this outdoor plant.
