Mostly deciduous trees and shrubs. Roots are large, fibrous and often stoloniferous. Leaves are usually alternate, lanceolate, pointed at the tips and toothed. Flowers are catkins and borne in spring.
Although willows are not legally declared pest plants (except for Salix fragilis and S. cinerea), they may still be invasive in some situations. Consider lower risk alternatives for your garden, such as native plants.
Water body margins, wet places.
Seeds dispersed by wind and water. Vegetative spread from stem fragments. Human-mediated dispersal through deliberate plantings.
Can form dense stands, outcompeting and displacing native plants.
Follow up treated areas 3 times per year. Encourage natural regeneration of native plants or replant treated areas where possible after 2-3 treatments to establish dense ground cover and minimise reinvasion.
CAUTION: When using any herbicide or pesticide please read the label thoroughly to ensure that all instructions and safety requirements are followed.
