The Q&A Archives: weeds in lawn

Question: What is the best way to get rid of white clover & crepping charley in the lawn?

Answer: Clover tends to thrive in a lawn that is undersupplied with nitrogen, so you might want to run some basic soil tests and check the fertility and pH. Then fertilize and/or spread lime based on the test results.

Creeping Charlie or ground ivy (Glechoma hederacea) is very difficult to control. You could treat it with an herbicide containing triclopyr (read and carefully follow the label directions) and then replant the grass. September is the best time of year to seed lawn grass.

Be sure this is an area where grass would thrive -- Glechoma sometimes invades areas that are not suitable to lawn grass, such as shaded spots. Lawn grass needs full sun all day or at least half the day.

Your local Penn State cooperative extension should be able to help you with the soil tests and interpreting the results. They should also be able to help you with a lawn care and maintenance plan based on the growing conditions in your yard. Good luck with your lawn!
