The Q&A Archives: Crabgrass

Question: My lawn is being taken over by crab grass. What could I do to stop this, so I can have nice green grass again.

Thank you.

Answer: The key to a healthy lawn is good maintenance. The most important thing you can do is fertilize in the fall and then mow often. Mow often enough that you never cut off more than one third of the grass height at a time. Set your mower blades at two inches to enable the grass to shade out weeds.

Also, run some basic soil tests to determine how much fertilizer is needed and also check the pH to see if you need to lime. Your local county extension should be able to help you with the soil tests and interpreting the results.

Next, check with your county extension as to the best varieties of grass for your local area and ask them to help you develop a regular lawn maintenance plan based on your soil test results and the type of grass you are growing. Good luck with your lawn this summer!
