Watering, pruning, propagation, and repotting details from plant data
Humboldt's Willow thrives in consistently moist soil. Water regularly, especially during dry periods, ensuring the ground does not completely dry out.
Deep watering is preferable to frequent shallow watering to encourage robust root development. Monitor soil moisture by feeling the top few centimeters.
Prune in late winter or early spring before new growth begins. Remove dead, damaged, or crossing branches to maintain the tree's shape and health. Pruning can also be used to control size and encourage denser foliage.
Heavy pruning can rejuvenate older trees.
Humboldt's Willow is easily propagated from softwood cuttings taken in late spring or early summer. Dip cuttings in rooting hormone and plant them in moist, well-draining potting mix.
Alternatively, hardwood cuttings can be taken in late autumn and planted directly into the ground.
Repotting is generally not applicable for mature trees planted in the ground. For container-grown willows, repot every 2-3 years in spring into a slightly larger pot. Use a well-draining potting mix.
Ensure the root ball is kept moist during the repotting process.
