Unless you have a history of weed problems, early spring probably isn’t the best time to fertilize or apply herbicides to grass, the Cornell Horticulture blog recently posted.
In the recent post Lawn myth busting: Skip spring ‘weed and feed’, the blog explores the dos and don’ts of lawn herbicides and fertilizers.
“If weed and feed has become a ritual for you, it’s time to break the habit,” the blog post says. “Try skipping it this year and applying fertilizer and herbicide only if you need them and in separate treatments at the times when they will be most effective.”
The blog post also shares other lawn tips such as to seed thin areas and damaged spots.
“Spring is a race for space between grass and weeds,” the blog says. “If you can see soil, broadcast and rake in grass seed to fill that space.”
In the above video, Frank Rossi, a turf specialist and associate professor in the Department of Horticulture at Cornell University, demonstrates how to fix a dog spot on a lawn.
