> height up to 1', generally shorter
> leaves dark green with light patches, divided into three toothed leaflets
> central leaflet on the plant stalk
> flowers generally have 5 (sometimes doubled to 10) bright yellow (glossy) petals and grow singly on long grooved stalks
> flowers generally bloom March to August/September
> "fruits" are firm clusters of 20-50 achenes on round-prickly heads, each producing 20-150 seeds, dispersed by wind, water, and animals
> seeds can last up to 80 years in waterlogged soils
> creeping stolons (runners) with short swollen stems, can root at stolon nodes
Creeping buttercup can overwinter as a rosette or die back to ground level, storing nutrients in short swollen stems that growth rapidly the next spring.
> promote healthy grass by over-seeding, fertilizing as needed, and not over-grazing;
> add lime to improve grass health and keep buttercup from re-establishing (lime won’t control buttercup that is already well established);
> improve soil drainage and reduce compaction by aerating and avoid trampling when soils are wet;
> clean mowers and other equipment to avoid spreading buttercup seeds;
> remove all of the runners, roots and growing points by trowel (this is most effective from fall to spring while the soil is moist and roots break off less);
> incomplete removal of roots and stems may increase the buttercup population (they can sprout from nodes along stem and root fragments);
> soil can increase seed germination (the number of seeds in infested soils can be immense compared to the number of plants present);
> creeping buttercup’s growing point is at soil level, so plants resist mowing and quickly re-sprout when cut;
> regular cultivation can kill the buttercup but plants buried by cultivation can grow back up through deep soil and re-establish themselves and long-lived seeds in the soil can germinate and re-infest the area once cultivation ceases;
> herbicides can be used if allowed and appropriate for the site and land use (use great care to follow all label directions to ensure safe and effective use).
> usually requires at least two or three applications to eradicate creeping buttercup because of the seed bank and because some mature plants will generally recover;
> carefully monitor the treated area for re-growth and pull up any new seedlings before they establish runners.
