Bulbous Buttercup [Ranunculus bulbosus]
Bulbous buttercup is a very common tufted perennial weed, and it takes its name from the bulb like swollen underground corm. When the foliage dies back at the end of the season, this underground corm survives until the following year, when it will re-emege again.
Although it can cause problems in lawns it is not as common at the creeping buttercup. It is more common in fields and other grassy areas.
The leaves are divided into three leaflets which are deeply lobed. The yellow flower is typical of all buttercups, flowering between March and August.
Bulbous buttercup will grow in most conditions, but it prefers dry, alkaline soils.
Bulbous buttercup may be hand weeded if the plants are few in number. Encourage healthy turf with good lawn care practices to help prevent weeds invading.
For a serious invasion, chemicals may be needed to control bulbous buttercup, therefore choose a selective weed killer that will control this weed.
It should be noted that this weed can be difficult to control with chemicals and in most cases more than one application will be required.
When using weed killers in the garden always wear the correct protective equipment and clothing. Always read the product label and follow the manufacturers health & safety recommendations and application guidelines.
