- Manual removal is best for small patches. Make sure to remove the entire plant including any root or stem fragments to ensure new plants won’t sprout.
- Place all plant material in a tied plastic bag and throw it away in the trash— not your yard waste bin or home compost.
- Tilling and mowing only increases the size of the infestation. These practices should not be used when treating creeping buttercup.
