Although their bright yellow-and-white heads may look cheerful, daisies can be a nuisance to gardeners. In some gardens, they serve as ground cover, but in others these quick-spreading perennials can colonise a lawn, creating unsightly disruptions. Removing daisies is simple, but requires patience and thoroughness. These plants can be eliminated by hand or using chemical herbicides; in either case, prompt action makes dealing with the problem much easier.
Removing daisies by hand
Locate the daisies you want to remove. If you have only a few plants to get rid off, a simple hand approach is best.
Dig up each daisy using a small knife or a specialised daisy grubber. Make sure to remove not only the flower and stalk but the leaves and roots of the plant.
Examine the affected area regularly to make sure that daisies are not reappearing. Dig up any plants you may have missed.
Killing daisies with herbicide
Select a herbicide to treat your lawn. There are a number of products on the market, many of which contain methylchlorophenoxypropionic acid, commonly known as mecoprop. Check the packaging to see if a herbicide is recommended for use on daisies.
Dilute the herbicide with water if necessary, following the instructions on the packaging. Pour the mixture into a watering can or sprayer.
Spray or pour the herbicide on any areas where daisies grow. Repeat this process according to the schedule on the herbicide's packaging or until the infestation is gone.
Carefully rinse the watering can or sprayer. Be sure that all herbicide residue is rinsed out before reusing it.
Always follow the safety instructions on your herbicide's packaging.
