General Information: Silverweed, often mistaken for Creeping Cinquefoil (same
family) is a perennial weed and is a common weed on neglected lawns and turf in the UK. It is
rarely a problem on well maintained lawns. It spreads by creeping stems which root at
Leaf: Silverweed leaves are a silver colour on the underside of the leaf hence
the name. Leaves are similar to those of the creeping cinquefoil, the difference being (aside from
the silver underside) silverweed leaves are of a 'pinnate' structure, meaning that they are
arranged on opposite sides of the stalks. Each silverweed leaf contains 6 - 14 toothed leaflets,
whereas cinquefoil has only 5 leaflets.
Flower: Silverweed flowers are yellow and are visible from May to August,
producing 5 petals.
Preferred habitat: Silverweed can grow in most soil conditions but is very is
common on neglected lawns.
Control: The treatment for this weed is pretty much the same as Creeping
Cinquefoil. Regular raking or light scarifying will help weaken silver. For a serious problem use a
selective weed killer containing Dicamba or Mecoprop or alternatively a modern mixture such as
fluroxypyr & clopyralid such as 'Verdone Extra', a repeat application about 6 weeks later will
most likely be needed.
