The Best Lawn Fertilizer Brands Reviewed

best lawn fertilizer

When you have a lawn, it’s common to want to make it look nice. After all, unkempt and dying lawns are less of a symbol of a green thumb and more of the start to a bad horror movie. Freddy Kruger probably did not have the best lawn fertilizer.

Keeping up with your lawn can bring in that luscious green color you crave while also helping out the ecosystem. Lawns are green, so they undergo photosynthesis, the process of taking in carbon dioxide and putting out oxygen. The roots of the grass also keep the soil structured and able to absorb more water, which cuts down on flooding during a nasty storm.

Why You Need the Best Lawn Fertilizer

Having the best lawn fertilizer will, by extension, give you a great-looking lawn. And a healthy lawn will improve many aspects of your outdoor space. Along with helping to prevent erosion, it’s also a boon to wildlife. A healthy lawn means it’s easier for little critters like earthworms to live in, which increases nutrients in the soil. And healthy soil means a better, brighter garden and a lawn that’s resistant to pests and disease.

What lawn fertilizer does

Lawn fertilizer is something that you apply on your lawn. Most comprise of nutrients like potassium, phosphorus, and nitrogen that promote the growth of grass. Each chemical has its own purpose, but overall, they all work together to help your lawn grow and thrive.

When you buy a bag of lawn fertilizer, you should take into account when you’re going to be using it. There are some lawn fertilizers meant for fall, while others are better when you spread them in spring.

When you want to use it

Though opinions vary on the best times to spread lawn fertilizer, they typically find common ground in that the fall and early sprint is the best time to feed your lawn. During the fall, you’ll want to spread lawn fertilizer to give the soil some strength as it begins to get colder and the ground hardens. Once the snow melts and the ground thaws, spreading lawn fertilizer in the early spring will give you the best chance of having a flourishing lawn in the later spring and summer months.

Some fertilizers are specifically designated for these seasons. The ones marketed toward the fall usually contain a greater amount of phosphorus, to give the lawn stronger roots, while the ones for spring contain more nitrogen to promote green growth. When you’re picking out a bag of fertilizer, it will usually have a ratio of the chemicals listed on the bag.

How to apply lawn fertilizer

Lawn fertilizer comes in a liquid and a solid form. These naturally have different application processes and various benefits.

Liquid fertilizer must be diluted with water and spread with a special applicator made for liquid fertilizers. Though the results are quicker than a solid fertilizer, you’ll need to reapply them more often. Also, you could end up killing your lawn if you don’t dilute it correctly or apply too much.

Solid fertilizers are for most typical lawn lovers. They’re more expensive, but they don’t come with the high risk of burning your lawn because of the way they release the chemicals. Additionally, you do not need to reapply it as much as you do with liquid fertilizer. The best lawn fertilizer will do the work for you and keep your grass green and happy.

Be Aware of the Environment

Though lawn fertilizers can make your lawn look great and be great for the ecosystem, larger doses can do more harm than good.

Most lawn fertilizers contain large amounts of nitrogen and phosphorus. Though these chemicals are great for lawn growth and hardiness, they’re also one of the leading sources for algal blooms. These blooms are not the kind of growth you want to see.

When it rains after you’ve fertilized your lawn, parts of the fertilizer are washed away into sewers or anti-flooding systems. The systems usually lead to a body of water, often a lake or a river. The fertilizers release their chemicals just as they would on your lawn.

The chemicals build up, causing a bloom of algae that often covers the surface of the water, preventing fish from getting the oxygen they need and killing off entire water ecosystems.

Be conscious of the environment, and if you can, try to avoid spreading fertilizer when it’s going to rain. Check your weather reports and make sure your dosages are correct, so you don’t kill the grass before it grows.

What We Considered

First, we looked at the reviews. The best lawn fertilizer is not going to have one star on Amazon, and it’s not going to come with a plethora of bad pictures from customers. We only chose to include fertilizers that had 4.0 out of 5.0 stars or better.

We also looked at the size. Lawn fertilizers can get pricey. Buying a product that’s only available in teeny tiny sizes is not efficient. In fact, it may make you decide you don’t want to keep up with your lawn anymore.

Another thing we took into account was the kind of fertilizers. Solid fertilizers are more practical for the typical homeowner, so those options were preferable over liquid fertilizers. However, we did include some liquid options.
