Control weeds now: The best time to defeat perennial weeds like dandelions is in the fall, when they are absorbing all the nutrients they can. Whether using herbicide granules or sprays, weed killers are best if used in steady temperatures above 60 degrees Fahrenheit and when the soil is moist.
Don’t scalp it: You may not have to mow the lawn much in the fall, but keeping it short (about 2-3 inches tall for most grasses) will prevent the grass from being matted down by leaves and Michigan’s wintery snow. Pay attention not to over cut though, as grass that is too short has fewer roots, which allows room for weeds to take over. Experts suggest that you never cut more than 1/3 of the grass blades at any one time.
Fall is the best time to fertilize: While grass is short and slowly growing, its roots are still growing quickly- and fertilizer can help your grass establish deep roots for optimal spring growth. Often just one application in early September and another in late October or early November is enough. In cold regions like metro Detroit, selecting fertilizer rich in nitrogen will allow your lawn the best winter protection.
Bye-bye Leaves: Although fall leaves are pretty, they should not be left to accumulate on your lawn all year. A mat of leaves can smother your grass and contribute to the breeding of fungal disease. Rake away leaves and compost them, or use a mulching mower to shred and spread them over your lawn like.
