Lesser celandine controls

Controls: Celandine has specialized overwintering buds which makes it difficult to control. People can control lesser celandine by repeatedly digging it out and sifting through the dirt for the buds; removal and covering the area with 4-6 inches of sheet compost and/or cardboard; smother with old carpet or plastic; repeated mowing every 3-4 weeks; use of herbicides to control vegetation. Celandine has spread by well meaning neighbors who have “shared” the plant with others since it blooms in the early spring and has a very bright yellow flower.
