Surge Broadleaf Herbicide for Turf is not specifically labeled for lesser celadine. Herbicides which contain the active ingredient glyphosate, such as Round Up, are effective in controlling (but not necessarily eradicating) lesser celandine. Applications should be made in late winter or early spring when leaves are visible, but prior to full flowering, and when temperatures are above 40°F. Glyphosate will impact other vegetation so try to target only the celandine. It may take 1-2 weeks before the full effects of the treatment are visible.
