If you’re planning to sow tall fescue seeds this year, you should know that this is a cool season’s grass. Many of you may be struggling to keep up with green fescue, and that’s precisely where our article will help you.

In this article, we’ll help you pick the best fertilizers for your fescue and guide you on using them. Our fertilizing guidelines will make sure that your patch of green fescue remains the talk of your neighborhood.

Let’s dig for the best fertilizers and learn how to use them the right way!

What Is The Correct Type Of Fertilizer For Fescue Grass?

There are many types of fertilizers available in the market. You’ll notice that most fertilizers have an NPK categorization. The NPK stands for nitrogen (N), phosphorous (P), and potassium (K). Whatever fertilizers product you are going to buy, make sure you check the NPK ratio beforehand.

For your fescue grass, it’s best to opt for a slow-release formula. Don’t go for high concentration as it can kill and burn your grass. It’s best to stick to a 3-1-2 ratio for fescue grass fertilizer. For example, you can buy a bag of fertilizer that has an NPK ratio of 12-4-8.

You must use a slow-fertilizer whenever possible. Most popular fertilizer brands will have a blend of slow-release and soluble forms of nitrogen. Your fescue will benefit immediately from the soluble nitrogen, whereas the slow-release nitrogen will take at least two to three months.

The Nitrogen Content

For the tall fescue, it’s best to use more slow-release nitrogen than the soluble one. A good fertilizer brand will have more than 40% to 50% of slow-release nitrogen. Read the labeling thoroughly and look for statements like, ‘containing 40% nitrogen in the form of slow-release’. It’s best to avoid fertilizing the fescue grass with dry fertilizers or hose-end sprays.

In this type of fertilizer, most of the nitrogen content is soluble and has a quick-release form. We are against this type of fertilizer because the effects last for only up to 6 weeks. During the initial days after the application, you might see abundant growth, but that is not a long-term effect.

You will also see that the fertilizing products come with a seasonal distinction. There’s a different fescue fertilizer for summer, winter, and spring. If you want your fescue to thrive in extreme temperatures, using these seasonal fertilizers can be helpful. It will also ensure that your grass is getting the right feed at the right time.

How Much Fertilizer Does Fescue Grass Need?

To reap the maximum benefits of your fescue grass fertilizer, you should first learn the correct amount. The first and foremost thing that you should check is the nitrogen content in your fertilizer bag. The right nitrogen concentration for fescue grass is 3-5 pounds per 1000 square feet.

This amount should be spread on your fescue lawn in three applications over a single year. It should not be more than 5 pounds regardless of the N-P-K ratio or the brand. If you have 1000 square feet lawn, you will require almost 1 pound of nitrogen in late winter.

The next step is to switch to a slow-release form of fertilizer. In the mid-spring and early fall, you need to apply about 1.5 pounds of actual nitrogen. Unfortunately, most brands do not mention the nitrogen content in the package or labeling.

However, you can calculate the nitrogen content from the NPK ratios. You have to multiple the nitrogen percentage by the total weight of the bag and then divide it by 100. For example, a fertilizer bag measuring 50 pounds and having an NPK ratio of 12-4-8 has an actual nitrogen concentration of about 6 pounds.

There are also other ways of determining this value. Always make sure that you are calculating the nitrogen before spreading the fertilizer. With fescue grass, the ideal amount is 1.5 pounds per 1000 square feet.

Therefore, if a bag has 6 pounds of nitrogen concentration, it can cover 4000 square feet. If your lawn is smaller than 4000 square feet, remove the extra fertilizer and store it. For helping you out with the measurement, 1 pound of granular fertilizer is equal to two cups.

Follow this simple calculation for actual nitrogen, and you’ll see stunning green fescue grass all over your lawn.

Spreading Fertilizer The Right Way

Many of you may be fertilizing your lawn for the first time. Our extensive fertilizing guide will also help you to spread your fescue grass with accuracy. You must not distribute the fertilizer by hand, as it will not maintain consistency.

You can use the two ways to spread the fertilizers – broadcast spreaders and drop spreaders.

Both these spreaders have flexible application settings. You have to read the manufacturer’s manual for the correct usage. You can find the proper settings for your spreader on the label as well.

Also, you may come across spray bottles for liquid fertilizers. These types of fertilizers have to be mixed with water for application. It is best to check the usage directions before mixing or using the product.

Broadcast Spreaders

The broadcast spreaders are perfect for maintaining a consistent spread. These units use a whirling mechanism to distribute fertilizer in a large area evenly. However, these spreaders are not as precise as the drop spreaders.

The broadcast models can be wheeled or hand-held. If you are working in a large area, we recommend buying a wheeled model.

Drop Spreaders

The drop spreader has more accuracy while spreading the fertilizer. However, you might not want to use the drop spreaders for big lawns. The drop spreaders are only apt for spot application.

Fertilizing Fescue Grass Throughout The Year

When it comes to fertilizing fescue grass, timing is the key. You have to stick to a strict schedule to ensure that the grass maintains its vibrant dark green color.

Our fertilizing schedule will help you to achieve the right balance between all the nutrients. It will prevent your lawn from damaging or diseases.

Later winter

As you know, fescue thrives better in the cooler season, so late winter will not be very challenging. You have to wait for the soil to maintain a consistent 50 degree to enhance the root growth. 

You need to follow this process in February or early March. Use low phosphorous and high nitrogen fertilizer, preferable an NPK ratio of 18-0-4. This fertilizing process will also help you to combat weed infestation.

We recommend that you refrain from using slow-nitrogen at this point. Pick an application rate of nitrogen that is around 1 pound per 1000 square feet. This combination will work correctly for most of the fescue lawns.


After 4-6 weeks of fertilizing in the later winter, your fescue grass will need fertilization again. This fertilization process should take place in the initial week of April. This time you have to opt for a complete fertilizing ratio.

Pick a fertilizer that has the classic 12-4-8 NPK ratio. It should also have an adequate concentration of slow-release nitrogen. This time, the rate should be 1.5 pounds per 1000 square feet. The secret to fertilizing the correct way is balancing the nitrogen levels.


In summer, it is not necessary to fertilize your lawn. However, if your yard is looking pale yellow or dull, a little fertilizer could be helpful.

You must be very careful and ensure that less fertilizer should go into your fescue grass. Don’t apply more than 0.5 pounds of actual nitrogen in a lawn that is 1000 square feet big.

Early fall

At this time of the year, you should get more active on the fescue lawn. It’s easy September, and your fescue will require the essential nutrients. You can stick to the same fertilizer you were using, or you can switch to an option with low or no phosphorous content.

Note that a little higher potassium content at this time can be fruitful for the lawn. The ideal ratio is somewhere near 12-0-12 or 12-4-14. In early fall, it’s best to choose a slow-release nitrogen formula.

The actual nitrogen application rate should be 1.5 pounds per 1000 square feet. Also, you don’t have to ‘winterize’ your lawn or apply any special fertilizer.


During the winter season, many lawn owners feel the temptation to apply another round of fertilizers. You must know that the soil may not be in the capacity to absorb the nutrients. The roots of the grass are unable to absorb any fertilizer when the temperature is around 45 degrees.

You should keep the fertilizing activities on hold during the cool season. A warm spell is an ideal time to spray some fertilizers on the off-color and dull lawn. All in all, this fertilizing schedule will ensure that the grass is always greener on your side.

Fertilizing The Tall Fescue

Fertilizing the fescue grass is not as difficult as other types of grasses. The fescue grass can overgrow and fill your lawn with greenery within just a few days.

 The best time to get active in your yard is during spring and fall. Remember that applying excessive fertilizer will not make your lawn greener. Instead, applying frequent fertilizer will just make the grass multiply faster.

In such situations, your lawn will require regular mowing. The fescues grow more quickly in colder periods and have an instant response to fertilizers.

Along with following a strict fertilizing schedule, you also need to take care of watering and mowing. You must be calculative while buying fertilizers and also applying them. You can only have those bright green lawns if you have put great effort into taking care of them.
