Care Guide
Watering
Willows thrive in consistently moist soils. Water regularly, especially during dry spells, as they naturally grow near water sources.
Sunlight
Plant in full sun to partial shade. They perform best and develop the strongest growth when receiving at least 6 hours of direct sunlight daily.
Soil and Fertilizer
Prefers rich, evenly moist loam or clay soils. Generally does not require heavy fertilization unless the soil is particularly poor.
Pruning
Prune in late winter or early spring while the tree is dormant to remove dead, damaged, or crossing branches and shape the canopy.
Propagation Methods
Cutting
Willow branches root extremely easily. Take hardwood or softwood cuttings and push them directly into moist soil or water where they will quickly develop roots.
