Since autumn is just around the corner, that means your lawn’s growing season is just around the corner as well. You may have noticed your grass slows down during the summer months—it doesn’t grow as fast, which means less mowing, and it often takes on a brownish hue, some might even call it “crispy.” This, of course, is completely normal for Michigan lawns. The hot summer months are the dormant period for cool-weather grasses.
But as the daytime temps dip into the 70s more regularly, and precipitation picks up, you can expect your lawn to start “growing and greening” again. With that, there are some things you can do to make your lawn healthier and thicker.
1. Fall is a great time to fertilize. Good Sweet Earth applies organic fertilizer (an alfalfa blend fertilizer) twice a year: in spring and fall. If you were going to only apply fertilizer one time a year, I recommend fall over spring. Why? A few reasons: First, fall fertilization gives your lawn some nutrients before the long, harsh winter. This will make it less distressed when spring rolls around. It also adds organic matter to your soil to help insulate the roots a bit. Second, if you’re applying slow-release organic fertilizer, it won’t break down entirely before winter sets in, which means there will likely be some semi-composted product still on your lawn in the spring; it’s sort of an early spring meal for your lawn which will help green it up early and get it growing strong. Finally, there are less weeds germinating in the fall, which means the nutrients you put in your soil will be more available for your grass, instead of those nasty invasive plants you’d rather not be fertilizing. If you're interested in having us apply some alfalfa blend fertilizer to your lawn, get in touch.
2. Fall is the ideal time to overseed. Like fertilizing, you can overseed in either spring or fall. I prefer late summer/early fall because your grass seeds won’t be competing for space with weed seeds as much. Those gaps in your lawn where grass isn’t growing are prime real estate for weeds. But as your soil gets healthier from organic lawn treatments, those gaps will fill in with grass—unless weeds get there first! In the fall, there are less weed seeds looking for a home, so putting grass seed down in late-August or earl-September (you could do it as late as the first part of October, especially if we have a warm fall) will ensure the grass has a head start over the weeds come spring. To overseed, first, mow your grass lower than you normally would; if the clippings are especially long or clumpy, rake them up so the seed can fall easily to the soil below. Second, buy a sun/shade mix and apply it with a spreader or scatter it evenly by hand. The rate you should be applying is typically 4-6 pounds per 1000 square feet (a 10,000 square foot turf space should be overseeded with about 50 pounds). For bare spots in your lawn: Mix the seed with a little potting soil (soil + compost) and apply it directly as a patch. If rain’s not in the forecast, water it regularly. Every year you do this will mean thicker and less weedy turf.
3. If you’re going to aerate your lawn, do it in fall. Summer is a bad time for aeration simply because you don’t want to distress your lawn any more than you have to during its dormancy. In fall, the grass is growing strong and can recover better from the aeration process. If you’re going to aerate, either hire a company to do core aeration (pulling plugs of soil out of the ground), or rent a core aeration machine and do it yourself. Do NOT succumb to the idea of putting spikes on your shoes and walking around your yard. That simply compacts the soil further. To properly aerate, you need to pull plugs out of the ground so that water and air can get in. Poking holes with spikes won’t do that. That being said, aeration is typically only necessary once every few years, and usually only with over-chemicaled yards. When soil is healthy, full of microbes, worms, bugs and organic matter, it doesn’t need core aeration—the worms and bugs and microbes aerate it for you.
We're excited to be part of the Fourth Annual Macatawa Water Festival this Saturday, July 14, at Windmill Island in Holland! The event goes from 9am-1pm, and is free to the public.
We'll be joining over 30 other community organizations promoting a cleaner, healthier Macatawa Watershed. Activities will include kayaking, fishing and crafts! Meijer will be there providing fresh fruits and veggies from local farmers.
Good Sweet Earth will be there (Steve & Corey) to talk about the importance of healthy soil and vermicomposting in relation to healthy watersheds, with a craft for the kiddos.
The Macatawa Water Festival benefits Project Clarity.
Windmill Island is located at 1 Lincoln Avenue in Holland. For more information, click here.
