Each flower consists of between 5 – 7 glossy yellow petals.
Measuring 20mm – 30mm across they are borne singular or in clusters on long, hairy stalks.

It is rare to find it on dry, free draining sites. A presence of creeping buttercup is often a good indicator of the aforementioned symptoms and remedial action needs to be taken to improve the drainage. It prefers heavy wet soils that often suffer from prolonged wetness and water logging. It is an easy weed to recognise with its lovely golden yellow flowers that can add an array of colour if the infestation is widespread.

Apply a herbicide to help reduce the population of buttercup plants in the spring plus use good pasture management techniques throughout the year to help improve and thicken the stand of desirable forages.Creeping buttercup is perennial weed and the most common of the buttercups found in turf. Consult the herbicide label for further information on grazing restrictions, precautions, or other possible limitations.įor fields heavily infested with buttercup a variety of control tactics may be needed. For best herbicide activity wait until daytime air temperatures is greater than 50 F for two to three consecutive days. For optimum results apply a herbicide in the early spring (February - March) before flowers are observed, when buttercup plants are still small and actively growing. However, legumes such as clovers interseeded with grass pastures can be severely injured or killed by these herbicide products. PastureGard, Crossbow), or metsulfuron (eg. Depending on other weeds present products that contain dicamba+2,4-D (eg. Mowing fields or clipping plants close to the ground in the early spring before buttercup plants can produce flowers may help reduce the amount of new seed produced, but mowing alone will not totally eliminate seed production.įor chemical control, herbicides registered for use on grass pastures that contain 2,4-D will effectively control buttercup. Whereas, livestock animals allowed to overgraze fields during the fall and winter months is one of the main factors that contribute to buttercup problems. Therefore, pasture management practices that improve and promote growth of desirable plants during these months is one of the best methods to help compete against the emergence and growth of this plant. Most buttercup plants emerge from seed during the fall or late winter months. This is one reason buttercups can survive year to year and new plants emerge each year. Waiting until after flowers appear can be too late to implement control tactics. New seed are produced during the time petals are showy. Although each of these plants may have somewhat similar flower heads, each of these buttercup species differs somewhat in their vegetative leaf characteristics. There are four different species of buttercups that may be found in Kentucky: bulbous buttercup (Ranunculus bulbosus), creeping buttercup (Ranunculus repens), tall buttercup (Ranunculus acris), and small flower buttercup (Ranunculus arbortivus). Plants typically produce five, shiny yellow petals in the early spring. In fact, many fields that have dense buttercup populations are fields heavily grazed by animals during the fall through the early spring months.īuttercups are sometimes classified as short-lived perennials, but often grow as winter annuals. As a cool season weed, this plant often flourishes in over grazed pasture fields with poor stands of desirable forages. Green, Extension Weed Scientist - One of the signs that spring has arrived is when the yellow flowers of buttercup begin to appear, but it’s during the winter months that the vegetative growth of buttercup takes place.
