So your having breakfast one morning and sitting by the window looking out at what a beautiful day it is. as your eyes are gazing into the sky, suddenly a spot appears in the corner of your eye. You look down and see that you have a dead spot in your grass.

Don't worry. Do not let this put a damper on your day. We don't get very many beautiful days it seems anymore so I will guide you through how to fix this without any worries, but first lets finish breakfast. I'm hungry.

Now that breakfast is over it's time to do some work in the yard. Lets start by completing a few simple steps and maybe we can even have this completed by lunch.

Step 1) Lets start by determining what type of grass you currently have. You can view some photos that may help you are watch the instructional video as well.

Step 2) Now lets measure the area to see how much soil and seed we will need to purchase.

Step 3) Purchase the same grass type seed as you have discovered your lawn currently has and enough soil to cover the area you previously measured.

Step 4) Lets dig the current dead area out using a round garden shovel. Start digging right on the border of where the dead area and the healthy area connect. Dig approximately 3 inches deep.

Step 5) once the dead area has been removed. Place about 1/2 inch of topsoil over the entire area previously dug.

Step 6) Go ahead and place a thing layer of grass seed over the soil previously applied.

Step 7) Repeat Step 5 and 6 one more time.

Step 8) Apply the almost all the remaining amount of soil to the area until it is level with the surrounding area.

Step 9) Apply more seed on top of the area that was just replaced with new soil. This should be done in a chicken feed type manner to avoid clumping. It is O.K to apply extra seed because there is always a percentage of seed that will not germinate. It is also O.K if you have some extra see to just throw it around the affected area as well to help blend the area together.

Step 10) Now place the remaining amount of soil on top of the seed, even if it is just a hand full or two.

Step 11) If you have a Roller, take your roller across the repaired area to flatten the area. If you do not have a roller, try using a piece of plywood by placing in on top of the area and walking across it several times.If no ply wood, try just walking across the entire area with your shoes to flatten the area.

Step 12) Keep this area moist. The objective here is to keep the area wet at all times but not to wet where it begins to flood. if it begins to puddle or wash away then stop watering until the flooding stops and resume later in smaller amounts.

Additional Note:
1) When preparing to purchase seed and soil, keep in mind that you will need enough soil to cover the entire area and go about 3 inches deep with it.

2) View the post on how to measure a lawn if unsure. Also located in this how to section.

3) It is important to purchase a seed that matches your existing turf for several reasons. Most grass blends are maintained differently and it will be difficult to maintain your lawn in the future if you have multiple blends of grass. Multiple blends of grass can clump easily or be unsightly if the blends are to far apart.

4) The purpose behind doing a layer of soil, then a layer of seed multiple times is because ultimately the top layer of seed will have a percentage of seed that does not germinate for what ever reason, or birds may eat it etc. Also if there are layer of seed beneath the soil, then once they begin to germinate they will have a strong root system being that they are buried deeper. It will take longer for those seeds to germinate though.

5) Applying the new to to meet with the existing soil will allow for the new soil to settle over time and allow for the a small layer of thatch buildup. If you find over time that the area is lower than the existing area because the existing area doesn't have a thatch buildup, apply about 1/2 inch more soil to the area.

6) Rolling the newly seeded area will help create a good seed to soil contact which will help more of the seed germinate and germinate quicker. It is important to have a good seed to soil contact as well as consistent water.

As I read through this article that I just wrote I get the impression that it seems more difficult than it really is. This is a very simple process that I have done thousands of times over my career. It is relatively inexpensive as well.
Depending on the grass type purchased, and that you water properly, you should begine to see some germination in about 2 weeks and should be pretty healthy in about 6 weeks.
