How to Remove Sweet William

Sweet William (Dianthus barbatus) is a flowering perennial that is common in landscaping and flower beds. They are small plants that only reach up to 20 inches high. The flowers come in a variety of colors, including pink and white, and are slightly fragrant. Sweet william self-sows readily. If you have a stand of volunteer sweet William in your garden that you want to remove, the easiest way to do so is to simply pull them up. You can also use a hand spade to assist, if the soil is hard.

Instructions

    • 1

      Water the soil around the sweet William thoroughly the day before you want to remove the plant. This softens the soil and makes removal easier.

    • 2

      Grasp the plant by the base, as close the soil as possible. Pull up firmly to remove the plant from the soil. Pull out as much of the root ball as possible.

      Use a hand spade to dig around the roots if the plant will not come up easily. Insert the spade into the soil 4 inches from the base of the sweet William at a slight angle. Push down on the handle to uproot the plant, then pull it until it is clear of the soil.
