7 Best Lawn Fertilizers of 2022 – Fertilizer for Green Grass

You surely know that your grass needs the best lawn fertilizer to grow healthy and lush. It is actually a necessary food supplement for your grass even though the soil in the region where you live is quite good. The purpose of fertilizing your lawn is to provide essential nutrients to the ground, effective pest control throughout the year, and to boost the well-developed root system of your plants.

The crucial thing you should take care of is to provide a correct ratio of primary nutrients such as nitrogen, potassium, and phosphorus, and enough oxygen, hydrogen, and carbon as well. Also, don’t forget secondary micronutrients such as calcium, manganese, iron, cobalt, copper, zinc, chlorine, nickel, boron, and molybdenum which won’t affect the soil, but will help your lawn become and stay lush and green in the long run.

Quick Glance: The Best Lawn Fertilizer on the Market


Buying Guide

Best Lawn Fertilizer for grass

Before deciding which lawn fertilizer is the best option for your grass, you need to understand the number system on the package. The combination of those numbers represents the NPK ratio of every fertilizer.

In general, every fertilizer is a mix of three primary nutrients:

  • Nitrogen for foliar growth and color
  • Phosphate for boosting the growth of flowers and roots
  • Potassium for increasing the ability of grass to absorb nitrogen

The desirable NPK is marked like – 20-5-10. These numbers show the percentage of these three nutrients in the package, respectively.

There are a few tips which will help you to choose the best lawn fertilizer for your grass.

​Organic Vs. Synthetic

Organic Lawn Fertilizer

Organic fertilizer

This type of fertilizer contains organic plant food such as alfalfa, blood meal, or kelp. Since it takes longer to start working, organic fertilizers release slowly


  • They are eco-friendly and give better effects in the long run
  • There is a low possibility of over-fertilizing


  • This type of fertilizer is quite expensive and pretty hard to apply
  • It often attracts pests and bugs


Synthetic (inorganic, manufactured, or artificial) fertilizer

Synthetic lawn fertilizer

The fact is that some of the best lawn fertilizers on the market are synthetic.


  • They are inexpensive and act quickly
  • With them, you will get the exact ratio of necessary nutrients


  • It can quickly over-fertilize your lawn or even become toxic
  • Your soil has no benefits of this type of fertilizer


​Controlled-Release Vs. Fast-Release Nitrogen Lawn Fertilizer

Controlled-release (polymer) nitrogen fertilizer

Controlled release lawn fertilizer

Since the nitrogen in this fertilizer is coated with the polymer during the process of manufacturing, the releasing of this nutrient is prolonged. In average, this process can last between two and twelve months after application.


  • This type of fertilizer will provide uniform growth of your grass
  • It probably won’t burn grass or disappear through the air or soil


  • It is possible that nutrients won’t be available for your grass when needed


Fast-release (soluble) nitrogen fertilizer

Fast release lawn fertilizer

This type of fertilizer releases nitrogen within one week and includes ammonium nitrate, ammonium sulfate, calcium nitrate, urea, and stabilized urea.


  • Greening of your lawn is visible right away
  • It is a quite inexpensive type of fertilizer


  • It may burn your grass or cause its undesirable excessive growth
  • You need to count on losses through both the air and soil


​Granular Vs. Liquid Lawn Fertilizer

Granular fertilizer 

Granular lawn fertilizer

Since it is a slow-release type of fertilizer, you can apply it less often. That will reduce the possibility of damaging your lawn.


  • You can apply it in the dry and hot season
  • There is no need for frequent application


  • You need to wait for a more extended period to notice positive results
  • The pH of the soil can adversely affect the effectiveness of this fertilizer


Liquid fertilizer 

Liquid Lawn Fertilizer

You can find this type of fertilizer as a water-soluble powder or concentrate of synthetic chemicals which you can apply by a sprinkler or spray bottle. Since grass absorbs this fertilizer quickly, you will need to apply it again after every two to three weeks.


  • They act fast and become available to grass almost immediately
  • The application and handling are quick and easy


  • If you don’t follow directions strictly, this type of fertilizer can cause grass damage
  • It is a severe water polluter
