Buttercup flowers look great as wildflowers, brightening up fields and hillsides. They are also at home in flower beds and rock gardens.

There are three ways to control and eliminate Buttercup weeds. First, you can handpick them. However, that can be laborious and you need to be certain that you get all of the roots. Second, you can alter their growing environment. For example, Buttercup weeds like low, acidic soils. The trouble with this method is that it can also negatively impact other plants that you want to have in the area. Finally, you can resort to chemical controls. This is very effective and okay to use in your lawn. But, if used in a flower garden, it can kill desirable flowers, too. And, you definitely do not want to use chemical weed controls in your vegetable garden.
Buttercups grow from seed or roots. The Buttercup seeds are difficult to germinate and takes weeks to sprout. Most people grow these plants from the division of the roots. Divide plants in spring or fall. Or, they can be bought at your local garden store.
Buttercups are invasive plants. Even small pieces of the roots can form a new plant. Make certain to use garden edging to keep them from spreading to other parts of your flowerbed, or into your lawn. It is important to control their spread.

Water established plants during dry periods and droughts.
In the fall, add a layer of mulch in cold weather areas. This will help protect the roots during the winter months.
Pruning is not required. However, like other plants, remove any sick or dead leaves and stems. Deadheading the blooms is not needed.
Insect and plant diseases do not appear to be too common. However, you may experience plant disease problems in wet, humid weather.
