Having a healthy and attractive lawn isn't really a "set it and forget it" operation. There's mowing, watering, fertilizing, and then there are other optional tasks like aerating, weeding and de-thatching.
But one relatively easy task many homeowners overlook when it comes to the health of their lawn is overseeding. Lawns can take a beating over the course of a year: pets doing their business, kids playing, high foot traffic, drought, squirrels digging, ice-melt run-off in the winter, and more. Turf can thin out over the course of a year, just from normal wear-and-tear.
That wear-and-tear can cause gaps in your lawn, and those gaps can make your yard look worn. Even worse, those gaps are where weeds pop up! Nature hates empty space. If you've got a gap on your lawn-- even a nickel-sized gap-- something's going to pop up there: crabgrass, Canada thistle, dandelions, chickweed, or other annoying plants. Now, I'm not opposed to some diversity in a lawn, but too much can make a lawn look ragged.
The best way to combat those weeds naturally is to take away the space where they're most likely to germinate, and the best way to do that is to overseed with a sun/shade grass seed every late-summer or fall (September-October). You can also overseed in the spring (April to early-May), but your grass seed will be competing for space, water and nutrients with weed seeds. Really the only time you shouldn't overseed is summer (late-May-August) and winter (November-March).
Good Sweet Earth sells an uncoated sun/shade grass seed perfect for overseeding in Michigan (and other cool-temp grass zones).
For areas where you struggle to get grass to thrive, we have an all-natural soil amendment called Lawn Soil, especially blended to help grass seed germinate and grow strong in its first month of life.
