"The Crabgrass Strategy So here is a strategy to rid your lawn of crabgrass and many other similar grassy weeds. In the spring, instead of using crabgrass killer, overseed your lawn to make it more dense. Then you raise your lawn mower to 2 or better 2 ½ inches for the whole season. You will still have some crabgrass, but not as much as last year. Then in the fall, overseed the lawn again. Keep that lawn mower high from then on and by the third year you will see very little crabgrass."
Create a Raingarden Did you know that stormwater runoff carries leaves, grass clippings, fertilizers and pesticides from streets and rooftops that are contaminating your lakes and rivers? The easiest way to help water infiltrate into the ground rather than run off into storm sewers is by creating a raingarden. Strategically place your garden on a site that will intercept rain water runoff. If constructed properly, the garden will drain the water within two days.
