Reinvigorate Your Lawn
By spreading grass seed over your existing lawn, you can thicken up the thin areas, and your lawn will start to look terrific again.
Thankfully, your dead grass will probably grow back with the proper care if you've caught the problem quickly (within about 3-5 weeks). Depending on why it died in the first place, you'll need to aerate, water, and/or manage unwanted pests.
If the plants pull out from the ground easily, they're probably dead. If the roots hold fast when pulled, the plants are dormant. You will also see the difference when you start to water or when rain returns as moisture will revive brown grass. However, it will not bring dead grass plants back to life.
You want to aerate the lawn when your grass is in its peak growing period so it can recover quickly—think early spring or fall for cool-season grasses, and late spring through early summer for warm-season grasses. If you have high-traffic areas or heavy clay soil, you will want to aerate every year.
Best Ways To Plant Grass Seed Over Old Grass
Definitely yes! Hand-sowing is the simplest method if you only need to cover a few spots. Take a handful of seeds and spread them over the dead patch, or better yet, involve your kids and introduce them to some basic gardening chores.
There are a variety of reasons your lawn may develop Brown patch, including high heat and humidity, excessive nitrogen, moisture, poor soil damage, too much thatch, and compacted soil. In some cases, you can't prevent your lawn from developing Brown thatch—after all, you can't control the weather.
It's your lawn's way of conserving energy and water, Mann explains. The grass will break dormancy and begin growing again when the temperatures and/or rainfall levels become more ideal for it. Note that when dormancy ends, grass leaves that have turned brown won't revive, but new leaves will appear.
Topdressing the lawn should be done right after aeration as it's not nearly so useful to do it without the holes already there. As mentioned, the idea is for the topdressing to mix in with the existing clay soil.
THE BENEFITS OF OVERSEEDING
The investment in overseeding pays off by reducing the amount of fertilizer, water and pesticides required. Most importantly, a renovated lawn stays greener and looks thicker and healthier!
You may want to rake the soil to remove debris and to loosen and expose soil. 2) If you're going to aerate, you'll want to do this beforehand. Typically, overseeding 48 hours following aerating is a best practice, as this will give the seed the best chance of getting into the soil.
Mowing actually helps make your grass grow thicker because the tip of each blade contains hormones that suppress horizontal growth. When you cut the lawn, you remove these tips allowing the grass to spread and grow thicker near the roots.
Keep Your Lawn Thriving
Epsom Salt is not just a good fertilizer for flowers or vegetables. If you want your front yard turf to look lush and stay healthy all year long, spray the lawn with an Epsom Salt solution once a month. This treatment helps grass seeds germinate and develop into strong blades.
Aerate and Overseed Your Lawn When Needed
Water and nutrients need to reach lawn roots in order to lead to thicker and greener grass. Over time, lawns can become compact, whether it's from traffic or harsh weather, limiting this easy access of water and nutrients. The solution is annual aeration.
No, watering dead grass will not restore it.
One easy way to see if your grass is dead is by pulling it up lightly. If the grass is dead, the roots will be easily ripped from the ground. If it is dormant, the roots will be stronger and hold on to the ground.
It depends on the type of grass. Kentucky bluegrass has runners that help it spread on its own. But many northern grasses are bunch-type grasses which don't spread, so seeding is needed to fill in bare spots. Perennial ryegrass and fescue are among the non-spreaders.
Don't mow a brown, dormant lawn on your regular schedule
When your grass has turned brown, don't mow your lawn just because it's Friday night and that's when you always do it. In fact, you should never mow your lawn if it's less than three inches tall, whether it's green or brown.
If you're unsure whether your grass is dead or dormant, you can try irrigating and waiting a few days to see if it starts to green up. For a quicker test, give the grass a good tug from the base of the blades. Dormant grass still has a healthy root system and will be hard to pull out.
For best results, aerate the lawn first, then spread seed and fertilizer afterwards. Going in this order - aeration, seeding, then fertilizing - allows the seed and fertilizer to fall into the aeration holes and make full contact with the soil.
After Aeration Overseed and Fertilize
The holes provide excellent soil exposure for seeds and deliver fertilizer directly to the roots of your grass. For best results, use high-quality seed and fertilize with Milorganite®. Mixing grass seed with Milorganite is an effective way to spread seed accurately.
