5 Best Fertilizer for Grass in Summer – {Review 2023}

The use of fertilizer is an absolute must throughout the summer. Maintaining the health of your yard requires taking measures to stop the spread of major harm. If you do not fertilize your lawn regularly, it will become unhealthy and awful. As a result, summer lawns need careful consideration of the most effective fertilizer options available.

It is just as crucial to have a working knowledge of the nutrients and that you need to apply fertilizers appropriately to your lawn. Hence, to keep lawns, gardens, and plant life in forested areas in good condition, different fertilizers are required at different periods of the year.

The numbers 6-0-0, 10-0-4, and 15-0-8 are the optimal numbers for lawn fertilizer throughout the summer. The amount of nitrogen required by warm-season grasses is often much less than that required by cool-season grasses.

First things first, you need to determine what kind of fertilizer your lawn needs and how much of that fertilizer you will need to buy and spread. The findings you seek might likely be found through conducting a soil test. Either the test will be sent to you by the local extension agency, or you will be able to conduct the test independently with the assistance of an appropriate kit. You can make a wise decision about lawn fertilizer if you have the necessary information at your hand.

The following list is the top five best fertilizers to use on grass throughout the summer.

4. The Andersons Professional PGF Complete Fertilizer

The Andersons Professional PGF Complete Fertilizer

The production of this fertilizer by Anderson’s required the use of non-hazardous inorganic components such as ammonium phosphate, urea, potassium sulfate, and ferric oxide, among other ingredients. In addition, these compounds include 16% nitrogen, 4% phosphorus, 8% potassium, 2.72 % sulphur, 3% iron, 0.10 % copper, 0.10 % manganese, and 0.10 % zinc. To the best of their ability, it seems that the company did a fantastic job of ensuring that the grass received the appropriate quantity of micronutrients.

Except for a trace quantity of nitrogen, almost all of the nutrients in this fertilizer are soluble in water. The only exception is nitrogen. Tall lawn grass may continue to rely on the fertilizer for up to eight weeks, although this depends on the slow-release nitrogen provided by the fertilizer. Because of the rapid and sustained feeding processes that grass undergoes, slow-release fertilizers like this one may prove to be quite beneficial to the grass.

Aside from that, the nutrient-rich combination that is included in the composition of this medium guarantees that your plants will grow equitably. Because the nitrogen content of the fertilizer is lower in those areas of the lawn where the grass is less green and apparent, it is essential to apply additional nitrogen particles to those areas of the lawn. In addition, the actions that you are doing will not harm the plants that you have.


  • NPK ratio: 16-4-8.
  • Slow-release.
  • Granules.
  • Applying it is a breeze

Direction for usage:

Prior to applying the product, you must first mow the lawn. Apply to regions of dried plant leaves. You must wet it down thoroughly once you’ve applied it. You should wait for at least one mowing before picking up any particles in the clippings that have been gathered after the application to avoid this.

On cool-season grasses, use 50-75% of the usual rate throughout the summer. The normal treatment rate should be reduced by 50% in centipede lawns. PGF Complete may be applied every six to eight weeks throughout the growing season.

  • Extra-fine particles double the number per square foot of ordinary particles
  • There is a direct correlation between how many particles are there and how equally scattered they are
  • A lower nitrogen content allows for more particles per square foot to be applied
  • Feeds for up to eight weeks on a low dosage
  • For increased soil quality and nutrient uptake, apply Humic DGS

5. Medina – Ready-to-Spray HastaGro Lawn

Medina - Ready-to-Spray HastaGro Lawn

Frequently Asked Questions:

How do you apply fertilizer to a lawn?

The most efficient way to distribute fertilizer is to use a sprayer with a pump to apply liquid fertilizer and a spreader to provide granular fertilizer. This will ensure that the fertilizer is evenly distributed. For water-soluble fertilizer, a hose-end fertilizer dispenser is the best option.

Is it possible to apply fertilizer on damp grass?

Yes. Precautions should be taken in this situation since the fertilizer might be lost if water is still running off the grass after it has been applied.

When Should Lawn Fertilizer Be Applied to Get the Best Results?

There are some times of the year when you should not fertilize your lawn. It is not good to fertilize your lawn while the sun is beating down on it since it might burn the grass. The late afternoon or early evening is often considered the best time to apply fertilizer to a lawn. Of course, every lawn is unique in its way. If you have a lot of shade or tree cover, the time of your fertilizer application may be more unpredictable.

What should I do before fertilizing my lawn?

Mowing and raking the grass are usually recommended before applying lawn fertilizer. It is important to hydrate your lawn and eliminate debris before fertilizing it. When excess debris is removed from a garden by mowing and raking, the soil may be exposed to fertilizer with more ease. When you hydrate your lawn, you create an opening in the turf that allows fertilizer to penetrate the soil and reach the grassroots more easily.


Your landscaping should include grass since it is an essential component. Sometimes, it can seem yellow or sparse because of drought and other environmental factors. When you water it, you also need to give it the appropriate fertilizer to help it grow. 

Nevertheless, it is up to you to determine which course of action is most appropriate given the circumstances of your case. You need to pay close attention to the vitamin content of the food you feed to avoid the risks associated with overheating. 

These treatments will not affect the grass seed you use or damage an already established lawn. They are also helpful in weed control, particularly in the treatment of grasses. To establish the temperature of the soil at which grass should be grown: a soil test and a thermometer should be used.
