What Should I Look For When Buying Lawn Fertilizer?

There are dozens of different kinds of fertilizers on the market today, each claiming to be the best fertilizer for specific reasons. However, what is most important is finding the fertilizer that is best for your unique lawn and its specific needs.

Here we will be breaking down a few important criteria to consider before purchasing a new lawn fertilizer so that you can narrow down your search and easily choose the one that will work best for your lawn.

Type of Fertilizer

There are three main types of lawn fertilizer. These include organic, synthetic, and liquid. Organic fertilizers are derived from all-natural ingredients which means that they are naturally occurring in soil. Organically sourced fertilizers contain zero chemicals and will not pose a threat to pets or wildlife. When using organic fertilizers, you also will not need to worry about water pollution, which can be a major concern if you live near a well-established water source. Organic fertilizers tend to take longer to activate than synthetic, however, so a level of patience is required when using them.

Synthetic fertilizers contain all of the nutrients that your lawn needs but are derived from chemical versions of these nutrients. Synthetic fertilizers will provide a much faster result in fuller and greener grass and will be much more effective at maintaining weed control than an organic fertilizer can. However, chemical-based fertilizers can be more dangerous to children, pets, and wildlife, and they will not provide the long-term, soil health benefits that organic can.

The third main type of fertilizer is liquid fertilizer. This type of fertilizer is usually a strong concentration of fertilizer that is mixed with water and then sprayed on your lawn along with the water either from a hose or a large pump sprayer. Liquid fertilizers work to provide an almost instantaneous effect by soaking the fertilizer into the soil along with the water. Liquid-based fertilizer will be absorbed into grass and soil the fastest, however, it will often need to be applied more frequently than granular fertilizers.

Application Process

Depending on which type of fertilizer your choose for your lawn, there is likely to be a different application process for each one. To find a fertilizer that works best for your specific lawn, it is important to find one that will be easy to apply to your yard.

If you own a large yard and need to apply a significant amount of fertilizer during each session, a granular fertilizer that can be applied with a rotary spreader may work best. If you have a smaller lawn, however, a liquid fertilizer may work best as it can be applied more often as needed.


Healthy lawns need several different kinds of nutrients to thrive. The three most important are nitrogen, phosphorus, and potassium. Before you begin shopping for the best lawn fertilizer for your lawn, it can help to perform a simple soil test that can tell you the current nutrient levels of your lawn and what nutrients it is most in need of.

When shopping for fertilizers, you will base your purchase upon the NPK ratio of the fertilizer which refers to the nitrogen, phosphorus, and potassium ratio found in the fertilizer. Depending on the result of your home soil test, you can search for a fertilizer that includes the necessary level of nutrients as well as the secondary nutrients such as hydrogen, calcium, and sulfur that your lawn may need.

Another thing you should keep in mind when thinking about purchasing and using fertilizer is whether it will harm your family or pets. If you own dogs and they have the run of your property, you should really be asking yourself, “Can lawn fertilizer harm dogs?
