Black Willow thrives in consistently moist soil. Water deeply and regularly, especially during dry periods and the first few years after planting.

Avoid letting the soil completely dry out, but also ensure good drainage to prevent waterlogging, which can lead to root rot. Aim for consistently damp, not saturated, conditions.

Pruning is primarily done to remove dead, damaged, or crossing branches, and to shape the tree. This is best performed in late winter or early spring before new growth begins.

For shaping younger trees, consider thinning out branches to improve air circulation and light penetration. Avoid heavy pruning during the growing season.

Black Willow can be easily propagated from stem cuttings. Take hardwood cuttings in late fall or early winter after the leaves have dropped.

Cuttings should be at least 15-30 cm long and planted in moist soil or a well-draining potting mix. Rooting is typically successful, especially in moist conditions.

Repotting is generally not necessary for established Black Willows planted in the ground. For container-grown specimens, repotting may be needed every 2-3 years to refresh the soil and provide more space.

Choose a larger pot with good drainage and use a well-draining, loamy potting mix. Perform this in early spring.
