Product Q&A

Answer:

Hi-Yield Triclopyr Ester is not labeled to control lesser celandine, so we are not sure if it would be effective. Lesser celandine is a very difficult plant to control, and you will probably have to use a non-selective herbicide such as RoundUp QuikPro to spot treat it carefully. 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.
