Lawn Repair Tips

You can achieve like new grass without tilling or removing the existing turf if you know how to lawn repair using our how to tips. I’ve been able to reform even the most hideous lawn into lush beautiful green grass without a tiller.

If you have just a few bare spots we have all the tips on
repairing bare grass areas here.


Here’s How:

This work can get strenuous so take your time. There’s nothing here that can’t wait until another day. Get someone to help you it saves on time and labor.

  • Cool season grasses get renovated in late summer
  • Warm season grasses in early summer

Plan ahead. Don’t just wake up one day and on an impulse decide you’re going to renovate a lawn. There are a few things that need to be done ahead of the actual process of lawn repair.

Soil Testing

If you can get your soil test done several months in advance it would be beneficial because the amendments you add can take quite a while to be effective. It takes a few weeks to get your results back so you want to get that sample into the lab as soon as possible. The sooner you add the amendments according to your results, the better.

repair lawnDepending on the size of your lawn area take 6 – 10 small samples from different sections using a small clean spade. Dig down about 3-6 inches, removing rocks or debris, mix the samples and let dry.

Place about one cup of the dry soil in a clean plastic bag. If you’re sending more than one sample make sure to label each bag for which part of the yard you took the sample from.

Your local cooperative extension department will test your soil for you for a small fee. The mailing address and other necessary forms should be available online.

Having your first soil test at a lab is important. They can give results home soil kits will not. If you want to get a home soil test we have some good prices here.

Lawn repair should always start with a soil test.

Lawn Observation

While we wait for our soil test results, take a stroll around your lawn and make observations.

Are there a lot of weeds?

Any spraying of weeds should be done as early as possible before your project begins, just make sure the weed is actively growing. Use an organic vinager based weed killer.

grass repairThis spray is non-selective, meaning it will damage any vegetation it touches. Just because something is labeled organic doesn’t necessarily mean it’s harmless. Get organic vinegar in you eyes it could blind you for a while.
So, be careful!

Organic weed killers are most effective if sprayed when it’s hot, dry and no wind. Get this done a few weeks in advance of over seeding because it takes a little while for the weed to die off.

We carry products for your lawn repair project including weed control.

For more information on weeds and eliminating them check out our weed page.

What You Will Need:

  • Have compost delivered
  • Reserve aerator thatcher rentals
  • Brew compost tea
  • Buy Grass Seed, Fertilizer
  • Rest

Assuming your soil test results have an organic matter percentage of less than 5%, you will need to order finished compost.

It takes 1 cubic yard of compost to cover 1000 square feet of lawn at a 1/3 inch depth

repairing dead spots

To figure out the square footage of your lawn repair area go here.

A few days ahead of time you will need to reserve a few items at the rental store. Those would be an aerator, thatching machine and a roller. Having a blower on the job site is also a big help. A few other items are necessary to complete this lawn repair project but they are cheap enough to purchase or borrow.

Read ahead a bit and you’ll see you will be aerating your lawn. Try your best to predict 24 hours before you’ve completed the lawn aerating and brew a compost tea with mychorrizhae.

Or it might be better to thatch and aerate the turf on one day and start the next day by spraying the compost tea. Read ahead and try to get a feel of the timeline of the lawn repair project.

There’s way too much info regarding compost tea to write on this page but all the info you’ll need is located at:

Do a little research or your location and the conditions in your yard. If you’ve had problem areas in the past like insect, drought or disease you can try using an endophyte enhanced grass seed.

Purchase 1 – 1/2 times the recommended amount as we will be seeding the lawn repair area twice.

Get a good nights sleep before project day. As I’ve stated before this project is much easier, faster and less expensive if you have help.

Get your neighbors involved and do a few homes in your area. It’s the best way to get this done. Other people will wonder what’s going on and then it gets contagious. The entire neighborhood is free from lawn chemicals and pesticides.

Repairing Grass Can Be Easy

Project day!

Even though I stress mowing the grass at 3 inches throughout this website, doing lawn repair is one of the times that you’re going to cut your grass short.

You’re going to beat up your turf pretty good with this process and mowing low will insure good seed to soil contact. If you can, gradually start cutting it shorter a couple of weeks ahead of time in preparation of your lawn repair.

Thatch

It’s a must to remove any thatch before over seeding, to ensure a good soil to seed contact. If you stick with treating your lawn organically then this will probably be the last time you’ll need to remove thatch from your lawn.

In a natural lawn, fungi breaks down thatch as a normal biological process. Synthetic fertilizers and over watering your lawn help increase the build-up of thatch.
repairing lawn area

Thatching a lawn is very much like mowing. Just back and forth, overlapping your wheels.

Set the machine so it goes into the soil about 1/8 inch. This height will aid in removing thatch and any dead weeds.

Do a thorough job!

Thatch twice if you have any doubts that you didn’t remove all of it. The second time go over the lawn perpendicular to your first direction.

You can rake up any removed thatch but I highly recommend blowing the grass with a hand-held or better yet a back pack blower. Blowing the lawn hastens the process and it’s easier on the body. It also does a very good job, which is very important in lawn repair, so the grass seed can contact the soil.

You can read a ton more on lawn thatch here.

Aerating

We should now have a pretty clean surface with most of the weeds gone, the thatch removed and the lawn cut relatively short.

The next stage of lawn repair is to aerate the soil. Make sure you use a core aerator. Don’t use gimmicky aerating shoes or spikes penetrating into the lawn. If it isn’t coring a soil plug, it isn’t aerating.lawn repairs

Once again, you’ll want to do a very good job at this lawn repair stage.

It’s common for me to go over the lawn with the aerator 3 – 4 times when repairing a lawn. This will allow the compost to get into the soil.

Don’t worry about making a mess.

Your lawn should be littered with cored soil plugs ranging in size of 1/2 inch to 3 inches. The more the better. The best part of aerating is we just leave the plugs on the lawn.

You can call it a day now if you want. Depending on the man power at your site you’ve accomplished a lot. You can continue with your lawn repair now or begin seeding in the morning. Just remember to time your brewing compost tea.

Lightly spread a layer of seed

If you bought extra grass seed, you can put down a light layer now. It’s not necessary, as we’ll be seeding again later. It’s just effective to get some seed into the lawn repair holes and under the compost layer. I discuss seeding a bit further down the page.

At the most, broadcast only 1/2 of the recommended amount of grass seed as we will use the remainder in a bit. I understand it’s a bit more costly to buy extra grass seed but the better job you do now the less problems in the future. Having thick green grass solves many lawn issues before they begin.

Compost Tea

This is when we spray our prepared compost tea with added mycorrhizal. Try to time brewing the compost tea so it’s ready to use at 24 hours after you start the pump. Spray the lawn tea over the holes as best as you can.
repair the lawnThe better job you do repairing the lawn now the more beautiful your grass will be later. Cover the entire yard trying to hit all the holes. The tea loaded with microbes and mycorrhizal fungi will aid the seed that will germinate and the exposed root system from aerating. Try not to skip this step. The difference could be a mediocre lawn or amazing trouble-free turf.

Depending on your lawn repair schedule another compost tea with mycorrhizal brew should be timed with the upcoming seeding process.

Lawn Repair Organically


Top dressing the lawn

While our second lawn repair compost tea is brewing we’ve got to spread our compost. One cubic yard of finished compost equals 1/3 inch thick covering 1000 square feet. Don’t go any thicker than 1/2 inch.

After a couple of wheelbarrows you’ll get the hang of it. Just sort of fling it with a quick wrist action. The better you fling it the less raking spreading it later.

grass repairsThis is a great time to have a second person helping you with your lawn repair. One filling the wheelbarrow and one spreading. Once you get a rhythm down it goes pretty quick. I can topdress a lawn of about 5000 square feet in a few hours.

Now that you’ve spread the compost with a shovel it needs to be raked out. Try to get the majority of the compost off the existing lawn and onto the soil surface.

Remember, after raking it even, it should be 1/3 inch thick. Don’t exceed 1/2 inch. Add compost to any spots that you may have missed with the shovel.

I understand this section is a great deal of work. I do it on a regular basis. I also know how beneficial this lawn repair method is to a trouble-free turf.

This is the toughest part of the project. We’re almost done with our lawn repair. Remember, applying a layer of compost can be done any time of year as long as the grass is actively growing. It doesn’t have to only be done when renovating. It’s just nice to aerate before hand if needed, to ensure the organic matter is getting into the soil.

Seeding a lawn

You now have an option, you can use an over seeder and the machine will embed the seed 1/4 inch into the repaired lawn soil. If you do use this machine you should go over it twice. The second way would be perpendicular to the first. I generally don’t use the over seeder to save on customer costs but it can be a good practice if you’re not used to this process. The machine will also break up any clumps of compost you didn’t get with the rake.

I like to apply the seed directly on top of the compost so when I apply my lawn tea after grass seeding it makes good contact.
over seeding Hand held broadcast spreaders, are a nice little tool and they’re not too expensive. I try to use the hand-held spreaders for grass seeding instead of he walk behind spreaders. You just have more control of where the seed is going and the amounts you’re applying.

Do a good job. Nice even coverage. You don’t want to go through this process again.

Second application of compost tea

I know I harp on it all page long but try to time the tea brewing for when you’re ready to use it. Read the page links on compost tea I have at preparing for the project section.

Apply your lawn tea on top of the seed. Make good contact. Take your time. Do a good job.

Rake and Roll

If you didn’t use an over seeding machine to embed the grass seed into the soil now you have to with a back of a rake.

It’s a pretty simple process. Use a bamboo or plastic leaf rake and with the back of the rake, just walk the entire surface of the lawn repair pressing the rake firmly down. This will bury the seed about 1/4 inch deep. Make sure you cover the entire lawn repair surface.

lawn patch

Now we need to roll the entire yard. If you do not have access to one of these rollers, they’re inexpensive to rent. Fill it with water 1/8 to 1/4 way. Don’t put too much water in it. You don’t want to compact the soil. Roll the entire lawn repair surface. If you feel you need to go over again twice that’s fine.

planting grass

This ensures the seed adheres to the soil nicely which is very important. You don’t want all that expensive seed and hard work washed away with one heavy rain storm.

Fertilizing

Finishing up, we just spread a nice organic starter fertilizer over the entire surface. Something like a 2-4-2 would work well. Notice the middle number is higher than typical lawn fertilizer bags. Phosphorus is important seed germination and root development.

Applying Synthetic Starter Fertilizer

I’m asked all the time if I ever deviate from my organic methods. I’ll do whatever I can to keep someone from using a full synthetic fertilizer and pesticide program.

One of these times is with the starting fertilizer added at the end of the lawn repair process. Chemical seed starting fertilizers are very effective and quick acting.

The sooner the grass seed germinates and the lawn gets established the better organic future it will have. You will be happy with the results and be less inclined to go back to chemical fertilizers.

The thicker the grass stand the less problems the lawn will have which means less future inputs which is what we are striving for.

This should be a time you will want to cheat with synthetic fertilizers if you choose to.

Water
repair lawnThe final step of our lawn repair, as with just about any gardening project is to water the soil. We must keep it moist until at least the second to third mowing. Not to the point were the water runs off, just moist.

In cooler areas it’s a bit easier with autumn approaching. In the warm areas you really need to keep ahead of the game. So be careful. You don’t want to waste all that hard work and money lawn repairing on something as simple as watering the grass.

Keep Off The Grass

Ok, that wraps up the lawn repair method I use at Comfylawn Landscaping. Keep the grass moist until the third mowing and keep off the lawn repair surface as much as possible until it’s completely established. You’ll know when.

Because we used mycorrhizal fungi with our compost tea grass seed germination should be accelerated.

For example Kentucky Blue Grass usually takes 21 days to germinate. I’ve seen KBG germinate in 10 days with the added mycorrhizal.

Good Luck with Your Lawn Repair
