Contact allergens: Sap may cause mild skin irritation in sensitive individuals.
Airborne allergens: Pollen can be an allergen for some people during its blooming period.
Edibility: This plant is not intended for human consumption.

How to identify it

Distinctive weeping habit
Long, narrow leaves
Yellowish-green catkins
Rough, grey-brown bark
Graceful, arching branches

Height: 15 to 25m
Spread: 15 to 25m
Leaves: Green, deciduous
Flowers: Yellowish-green

Common problems

Aphids — Small, pear-shaped insects that feed on plant sap, causing yellowing leaves and stunted growth.
Willow Sawfly — Larvae skeletonize leaves by feeding on the tissue between veins.
Willow Scab — Fungal disease causing dark spots on leaves and twigs, leading to dieback.
Crown Gall — Bacterial disease causing tumor-like growths on stems and roots.
Wind Damage — Brittle branches are prone to breaking in strong winds.

Growing it

Propagation: Cuttings, Seed
When to plant: Spring, Fall
Overwintering: Weeping willows are hardy trees and do not require special overwintering care in suitable climates. Ensure they are well-watered before the ground freezes, especially if planted recently.
In containers: Not suitable for containers due to its large size and extensive root system.

Cuttings

Take 6-12 inch cuttings from healthy, current-year stems in late fall or winter.
Remove lower leaves and insert the cut end into moist potting mix or directly into the ground in a protected location.
Keep the soil consistently moist until roots form, which usually takes several weeks to a few months.
Transplant rooted cuttings to their permanent location the following spring.

Plant moisture-loving species around the base to create a lush, water-tolerant garden vignette.

Grows well with

Red Osier Dogwood — Both plants prefer moist soil and can help stabilize stream banks together.
Swamp Milkweed — This native perennial thrives in similar moist conditions and attracts pollinators.
Blue Flag Iris — Its preference for wet soil makes it a good companion for the willow's base.

Keep away from

Black Walnut — Black walnuts exude juglone, a substance toxic to many other plants, including willows.
Certain Lawn Grasses — The extensive root system of the willow can outcompete shallow-rooted lawn grasses for water and nutrients.

Salix matsudana 'Tortuosa' — Known as Corkscrew or Dragon's Claw Willow, it has dramatically twisted branches, not weeping ones.
