In 2006 you wrote; "Layman's tip: Let the frost kill off the crabgrass this fall, and make preventive applications to your lawn in the spring 30 days apart. Once around the third week in april, and again around the third week in may. You should also maintain an adequate fertility level as this will help your lawn fill in and compete against the crabgrass intrusion."
Anything new to know? I have had crabgrass and spurge in my front yard, soil is very compressed, and needs to be aerated and aggressively thatched. Have some moss too, which is new, so need to sweeten soil acidity. Want to do first pre-emergent treatment as soon as snow is gone. Eventually add some topsoil and overseed. Am I on the right track? What order and when? Still have 6-8 inches of snow (and road salt) on half of it, but it is melting fast. I have been known to overdo the lawn treatments, (fishermans fertilizer) which resulted in a brown lawn that did not take time away from fishing....
