Overseeding your lawn is a really important part of having a thicker, healthier and greener lawn with less weeds. It really isn't difficult to do, but it does require some knowledge to get the most germination for your buck. Read on to learn the why, what, how, when and where of overseeding your lawn. Keep in mind, we're a West Michigan-based company, so our recommendations are targeted for this region.
Where should you overseed your lawn? It doesn't take much space for a weed to sprout. Nature hates any empty space, so if there's a bit of soil showing, there's a good chance something's going to pop up there. You may not even see that empty space-- it could be as small as a quarter on your lawn-- but it's there. That's why it's important to overseed your entire lawn, every single year. Cover it, from corner to corner, with a sun/shade mix of grass seed.
Follow the application instructions on the bag; don't put down more than the recommended rate (typically, for a sun/shade mix, 2.5 pounds for 1,000 square feet of turf). If you're patching a bare spot, don't cover the entire space with seed, sprinkle it like you're seasoning a steak. Remember that grass spreads and more isn't better when it comes to grass seed.
