These things may vary slightly depending on which part you choose to grow. There are a few things to do in preparation for planting buttercups. After its first year, it can flower for up to 10 years and about 6 weeks yearly.Įven though few varieties can last up to 10 years, you’ll get several flowering years from most of the buttercups. ![]() Buttercup flowers are often used to make medicine for skin diseases, flu, nerve pain, etc, but since it’s very similar to several, poisonous flowers, be extremely careful if you want to use Bulbous buttercup for this purpose.īuttercups are perennials and usually do not produce flowers in their first year, depending on species. Their foliage is without a stalk, and even though they can grow in sandy and dry areas, they prefer a more grassy and rich soil. Its stems are slightly hairy, usually 8-15 inches tall and can grow up to 16 inches. Bulbous Buttercup (Ranunculus Bulbosus)Īs we already mentioned, Bulbous buttercups are an average size Ranunculus variety with fuller, yellow flowers. Let me show you some popular buttercup varieties you might be interested in growing. In contrast, the smaller varieties can grow up to 10 inches tall. How to Plant and Grow Buttercup Flower?Īround 600 ranunculus varieties grow in different shapes, sizes, and colors, with the average varieties growing up to 2 feet tall.Growing Conditions for Buttercup Flowers.California Buttercup (Ranunculus Californicus) Aconite Leaf Buttercup (Ranunculus Aconitifolius) Good agronomic practices are key to a healthy, persistent forage stand and should include proper fertility and soil pH levels and grazing and mowing management, along with effective and properly timed herbicide applications. Often it is a sign of over-grazing and a poor stand of desirable forage. Keep in mind, that pastures with dense populations of buttercup and other weed species in most cases are lacking proper management. Also, be aware that another weed called lesser celandine ( Ficaria verna) can exist in pastures and similar locations as buttercups and looks very similar. Most of these have a perennial lifecycle, however some can behave as a winter annual. On a side note, herbicides applied in fall (mid-September thru October) are not as optimal as a spring application but can still provide some control of buttercup.īuttercup species that are common to PA include: bulbous buttercup ( Ranunculus bulbosus), creeping buttercup ( Ranunculus repens), tall buttercup ( Ranunculus acris), and small flower buttercup ( Ranunculus arbortivus). So, be sure to consider all the tradeoffs when using this practice. However, by using this tactic, buttercup will likely only be suppressed, and clover growth can be temporarily stunted. If you are concerned about keeping white clover in the mix, 2,4-D (1 pint) could be used. Keep in mind, these treatments will severely injure or kill any legumes in your stand. ![]() When spraying in the spring make sure the air temperatures are at least 50F or more for a few consecutive days for effective control. Spraying when buttercup is flowering usually does not provide effective control. ![]() ![]() Since herbicide spray coverage is important, it is best to use higher spray volumes (at least 15 gallons/acre, but 20 gpa or more would be better) to allow the application do get into the sward and onto the weeds. Herbicides such as 2,4-D (2-3 pints/acre), 2,4-D (1 quart) + dicamba (1 pint), metsulfuron/MSM (0.2-0.3 oz), or Crossbow (2-3 quarts) are commonly used to control buttercup. The use of herbicides during early spring (Mid-March thru April) is the most effective time to control buttercup populations. Routine mowing can also occur during the rest of the growing season to thwart weed seed production and encourage pasture growth, but a well-timed herbicide application is important for best control.Īs for the best time to spray herbicides - the short answer is early spring. Mowing fields as low as possible during the early spring before they start to flower can help reduce seed production. A combination of mowing and herbicides will provide the best management of buttercup species. Do not wait until the pasture is "yellow" with buttercup flowers (as pictured above) to spray. However, this should not be considered a badge of honor. Pastures that are yellow because of buttercup infestations are a common sight during spring.
