Willows (Salix) such as the crack willow and grey willow form fast growing clumps of dense vegetation often near water as they tolerate flooding.
Identify the problem
Willows spread easily as stem fragments are spread by water, and suckers spread locally. Willow replaces native species in riparian sites and forms vast dense (often pure) stands along channels. Causes blockages, flooding and structural changes in waterways.
- Cut willow down to well below lowest green leaves and immediately apply thick layer of Weed Weapon Invade Gel or Weed Weapon Stump Stop Gel to cut stems and stumps.
- Or spray whole willow plant with Weed Weapon Rapid Action, or Weed Weapon Extra Strength plus Dye & Stick.
Stop willow returning
- Almost all cut stems will root where they are dropped and cut stumps re-sprout rapidly if not treated. Do not cut willow unless all plant material can be disposed of at a refuse transfer station or by burning. Best to treat with Weed Weapon Extra Strength plus Dye & Stick while standing to avoid live stem contact with ground.
