How to fix an over fertilized lawn?

It's not unusual to see a burnt grass in your backyard despite you did everything right, you water it and add fertilizer regularly, and still ugly, brown grass is present. If you ever wonder what is wrong with your grass and how to fix it, we will list some possible solutions. 

 

Why my grass turns brown at some spots?

There can be many reasons why your lawn is in such bad condition. One of them can be overwatering, and when that's the case, the roots won't die immediately and you will need to let the soil recover and dry completely. Still, probably the biggest problem is when your grass is over-fertilized.

You won't notice that at the first, you may think that brown grass areas could be because of the pet’s urine. That could be the case also, dogs and cats are well known because they can destroy the soil and flowers around your garden. Their urine is rich in nitrogen that kills your grass and turns it brown. 

However, if those brown areas are much bigger in your garden, you probably over-fertilized it. When you use fertilizer in normal, recommended amounts your grass will be healthy and lush but if you accidentally put in too much it will destroy your lawn. Before doing anything you should check the level of fertilization that is recommended for grass type you have because if you do it on your own, you can ruin your grass completely. Still, there are some ways how to fix it and we will show you. 

 

Symptoms of over-fertilizing

We will list you most common symptoms you will notice if you over-fertilized your grass. The first one is establishing the crust on the surface of the soil. Another sign is black, yellow, or brown hairs of grass. If your grass is slower in development and growth, that also indicates that you over-fertilized it. The main reason why these symptoms occur is that with over-fertilizing you add too much soil to the ground and that prevents water from reaching the roots.

 

How to deal with over-fertilized grass?

As we said earlier we will list you some possible solutions. Depend on how damaged is your grass you may apply only some of them or if it's too harsh all of them. 

The very first step you need to do is to check your grassroots. This is important to determine how serious it is, is it only grass that is damaged or roots system as well. If your roots are still fine and healthy, the only thing you need to do is watering your lawn. Make sure that during this check you check on a few critical areas. 

The next thing will be watering. It doesn't matter how harsh it is, watering is always good and recommended solution. For this use a garden hose or sprinklers. Water damaged brown areas of grass but also make sure to water the entire lawn to permit leaching fertilizer through your whole garden. Water will help you flush nitrogen and other nutrients that cause the damage. In this case, it's recommended to water your lawn about 5 to 7 days. 

Watering will help you in most cases and your problem will be fixed, but if after a week of watering you can still spot brown areas on your lawn, your problem is a little bit bigger then it seems. You need to examine your roots one more time. After that, the only solution you have is to replace damaged, brown areas of your lawn with a new one. Despite that, even if you notice at first that your problem can't be solved with water only, keep watering for at least one week to lush all nutrients. 

To prepare the substrate for your new grass you must rake all burned, brown grass and maintain tilling other affected areas of your lawn. Raking is the most simple way how to remove dead grass and tilling is also very important and it will help new roots to reach deep into the soil. 

The next thing you need to do is to decide and choose between re-sodding or re-seeding. It also depends on your available budget, but if we talk about a smaller area that is damaged you can simply re-seed it, but if it's a larger area of your backyard you will probably have to re-sod it. 

No matter which option you choose keep watering your lawn after you're work is done. Do it on daily basis for at least a week for good roots health. Your new lawn will spread faster and easier if the soil is well watered. Don't cut your new grass until it's about 3 inches tall. Regular watering and mowing it higher will give the best conditions for new roots.

 

Final thoughts

To sum up, in most cases you will be able to get rid of those ugly, brown areas on your lawn just by watering it. Make sure to check roots and determine how serious is the damage to your grass. Only in extreme cases, you will be forced to replace the damaged area. When your grass is healthy and lush again be careful when adding fertilizer again and water it regularly.
