How Does Lawn Fertilizer Work?

If you live in a place where year-round plant growth is just a green dream, then using fertilizer could be a godsend for your parched, perishing lawn. The right fertilizers help your lawn grow big and strong, enabling the development of healthy roots and thick, green grass blades.

Why? Because fertilizer provides your plants and grass with the nutrients, minerals, and vitamins they require to survive and thrive. Fertilizer does for your lawn what multivitamins do for humans. If you’re not getting enough of some nutrients, you take a multivitamin to stay healthy. The same goes for your lawn and fertilizer.

What Is in Fertilizer?

Most lawn fertilizers contain nitrogen, phosphorus, and potassium. The nitrogen helps your grass grow new blades. Phosphorus helps your lawn’s roots by making them stronger and more resilient. And potassium keeps your grass healthy and free of disease.

The number that you see on bags of fertilizer represents how much of each of these nutrients is in the bag. For example, a 10-10-10 has an even ratio of NPK, or nitrogen, phosphorous, and potassium (K is its element symbol).

When Should You Fertilize?

Before you purchase your fertilizer and apply it to your lawn you need to conduct a soil test. I know fertilizing is exciting, but you’ll be so thankful that you waited and did the test. Soil tests not only reveal to you when you should fertilize your lawn, determining if it needs nutrients in the growing seasons, colder seasons, or even both, it also gives you information about what fertilizer you should purchase.

It will help you figure out which nutrients your soil is lacking, which will inform your purchasing decision since you’ll want to get a fertilizer that’s dominant in those nutrients. It will also tell you what quantity of fertilizer you should buy.

Types of Lawn Fertilizer

Strictly speaking, there are two different types of lawn fertilizer: organic and synthetic fertilizers. They are very different when it comes to factors like how long they take to work, how safe they are to use, and how effective they are in promoting healthy growth for your lawn.

Below are descriptions of each, along with their benefits and disadvantages so you can make an informed decision about which one is right for you and your lawn.


Organic fertilizers typically are made with natural ingredients like kelp, alfalfa, seaweed, and blood meal. Typically, organic fertilizers are slow-release, not working as quickly as synthetic fertilizer products because they aren’t aided by anything artificial.

Because organic fertilizers use natural ingredients they are far more environmentally friendly than synthetic fertilizers which can release harmful chemicals into water runoff. They also are much safer to use on the lawns of homes that have children and pets since they won’t harm either.




Some of the most popular fertilizers available are synthetic because people love how inexpensive they are and how quickly they work. When it comes down to it, synthetic fertilizers are much more hassle-free than organic fertilizers, they’re even easier to apply.

Synthetic fertilizers make good use of science to improve your lawn, providing you with an exact ratio of nutrients so you know specifically how the fertilizer will benefit your yard. However, they do tend to include some nasty ingredients occasionally, which can be unsafe for children and pets. Be sure to read the label of your fertilizer before using it to make sure it’s safe, especially if you have kids.

Lawn Fertilizer Safety

Naturally, there are some safety concerns with using any fertilizer, whether it’s precautions for your lawn, your pets, you, or the environment. To make sure that you stay safe while caring for your lawn, use the safety tips below with your fertilizer.

Wear Gloves

Among all the safety tips, this is the one that’s the most important. You need to wear gloves while applying fertilizer, especially if you’re using a synthetic product.

If your skin comes in contact with nitrogen, you could experience a chemical burn which is extremely painful. If you want to go the extra mile safety-wise, consider also wearing goggles while applying fertilizer to your lawn. As much as fertilizer on your skin may hurt, fertilizer in your eyes will be ten times worse.

Store Safely

Whether you’re working with organic or chemical fertilizer, it’s important to keep it away from children and pets while storing it. Consider putting it on a top shelf or somewhere else where children and pets will not be able to reach it.

A good place to store it is in a garden shed or your garage. It should be kept in a cool, dry place, so if you live in a region that gets extra hot during the summer, you may want to move the fertilizer to an indoor area.

Carefully Apply

As important as it is to keep your safety, your family’s safety, and your neighborhood’s safety in mind, you’re also going to want to protect what you bought fertilizer for in the first place: your grass.

You certainly don’t want to burn your grass, so follow the instructions on the bag to the letter. Over-fertilization can happen easily, especially with chemical fertilizers. Imagine how disappointed you’ll be if you buy fertilizer to help your lawn and end up burning it.

Be Careful After Applying

Keep the possibility of runoff in mind while and after you apply fertilizer to your lawn. Once you fertilize your lawn, the chemicals are sitting on top of your lawn. So, keep pets and children off it until you’ve watered or it has rained, so the majority of those nutrients have settled into the soil or runoff in the groundwater.
