Algarrobo Blanco, Prosopis alba, is highly drought-tolerant once established. Water deeply but infrequently, allowing the soil to dry out completely between waterings.

In prolonged dry periods, provide supplemental water, especially to young trees. Overwatering can lead to root rot.

Pruning Prosopis alba is primarily for shaping, removing dead or damaged branches, and improving structure. Prune in late winter or early spring before new growth begins.

Remove suckers from the base to maintain a single trunk. Avoid heavy pruning, as the tree has a natural, spreading habit.

Prosopis alba can be propagated by seeds, which may require scarification or stratification to break dormancy. Cuttings can also be taken, but are generally more difficult to root.

Grafting is another method used for specific cultivar propagation, typically performed by specialists.

Repotting is rarely necessary for Prosopis alba, as it is a large tree adapted to open spaces. If grown in a container for a short period, repot only when root-bound, typically every 2-3 years.

Use a well-draining potting mix and a larger container. Minimize root disturbance.
