Keep the soil consistently moist, especially during establishment and dry periods. Salix rosmarinifolia thrives in damp conditions.

Water deeply and regularly, ensuring the soil does not dry out completely, but avoid waterlogged conditions which can lead to root rot. Reduce watering slightly in winter.

Prune in late winter or early spring before new growth begins. This can include removing dead, damaged, or crossing branches. Light pruning can be done after flowering to maintain shape and encourage denser growth.

For larger specimens, more structural pruning may be needed.

Easily propagated from softwood cuttings taken in late spring or early summer. Cuttings should be at least 10-15 cm long, with the lower leaves removed.

Insert them into moist, well-draining potting mix and keep in a humid environment until rooted. Can also be propagated from seed sown in autumn.

Young plants may need repotting every 1-2 years into slightly larger containers. Mature plants in the ground rarely need repotting. When repotting, use a good quality, well-draining potting mix.

Ensure the new pot has adequate drainage holes to prevent waterlogging.
