Watering. Keep soil consistently moist, especially during dry spells. Avoid letting the soil dry out completely or become waterlogged.
Fertilizing. Apply a balanced, slow-release fertilizer in early spring to support healthy growth. Avoid over-fertilizing, which can cause excessive leaf growth at the expense of roots.
Bay willow is a hardy tree that grows quickly and tolerates a range of soil types, especially moist soils. It prefers full sun to partial shade and needs regular watering, especially when young. It can be prone to pests like aphids if not cared for properly but generally requires moderate maintenance.

Salix pentandra, also known as bay willow, produces pollen that can cause allergic reactions in sensitive people, especially during its flowering season in spring. Symptoms may include sneezing, runny nose, and itchy eyes. To reduce exposure, avoid close contact during flowering and consider planting it away from areas where allergy sufferers spend time.
Common problems
Overwatering can cause root rot, while drought stress may lead to leaf browning. Pests such as aphids and caterpillars can occasionally affect the leaves. Poor drainage and lack of sunlight can weaken the tree.
Uses
Used ornamentally for its attractive foliage and flowers, and for stabilizing soil near water bodies. Also supports local wildlife by providing habitat and nectar.
Notes
Prune in late winter to maintain shape and remove dead wood. Repotting is not applicable as it is a tree typically grown outdoors. Sensitive to waterlogged soil, so ensure good drainage.
