Salix atrocinerea thrives in consistently moist soil, especially during its establishment phase. Water deeply and regularly, ensuring the soil does not dry out completely.

While tolerant of occasional waterlogging, prolonged drought will stress the plant. Reduce watering frequency slightly once established, but maintain adequate moisture.

Prune Salix atrocinerea in late winter or early spring before new growth begins. Remove any dead, damaged, or crossing branches. Pruning can also be used to shape the tree or encourage denser growth.

For vigorous shoots, coppicing (cutting back to near ground level) can be done every few years.

Salix atrocinerea is easily propagated from hardwood cuttings taken in late autumn or winter. Select healthy, one-year-old shoots, cut them into lengths of 15-30 cm, and insert them into well-drained soil or pots.

Keep them moist and protected until they root, usually by spring.

Repotting is rarely necessary for Salix atrocinerea as it is typically planted as a larger specimen or allowed to grow in situ. If container-grown, repotting every 2-3 years into a slightly larger pot with fresh, well-draining compost may be required to prevent root circling and ensure adequate space for growth.
