Creeping Buttercup
( Ranunculus repens )
Perennial spreading by seed and creeping surface stems. A problem in lawns as it forms a rosette at soil level, so resists mowing. Flowers from May to August.
Height - up to 30 cm on open ground. Dig out, clearing all of the runners, white fibrous roots do not regrow, but ensure that the crown is removed. Rake up the creeping stems before mowing Weedkillers to use:-
Glyphosate, systemic action killing the whole plant. Apply as spot weeder in the lawn. Treat the whole lawn with a selective weedkiller on its own ( eg. Verdone ) or a weed-and-feed type, it will probably take two or three applications to eradicate it.
