8 Best Lawn Fertilizer – Full Overview

Your lawns need essential nutrients to look beautiful and healthy, just as the human body needs the necessary food supplements to look healthy. We learned to eat a balanced diet, that is, eating the right portion of the food classes. Lawns also need some primary nutrients to thrive because each nutrient has a different function it performs for your lawns.

Nutritionists tell us we need to feed our body with these nutrients from our diets, not minding that our body has a few of these nutrients. As the body grows and works, the nutrients get burned, and we must replenish them back. You might think your soils should have the necessary nutrients to make your lawns healthy and beautiful, but that is not always the case, as these soil nutrients may not be enough for your growing grasses.

Fertilizers are generally substances added to plants or agricultural products to improve them. And yes, Lawns also have fertilizers with these needed nutrients in the right proportion.

The primary nutrients required by lawn grasses are Potassium, Phosphorus, and Nitrogen. Nitrogen is a mobile nutrient as it moves through the soil with irrigation water and rain; thus, it needs to be replaced to maintain healthy and green grass. The other two nutrients, Phosphorus and Potassium, are immobile and are sufficiently available in the soil until the plants use them.

Besides the essential three nutrients your lawn needs, you should also be aware of the levels of other secondary micronutrients such as manganese, iron, calcium, zinc, cobalt, and a couple of others.

Buyer’s Guide

Primary Nutrients

There are primarily three nutrients that have their unique importance to the lawns


Phosphorus is a nutrient that helps your grass develop very healthy stems and roots. The stems and roots of your lawn grasses help give it stability, which shows just how necessary Phosphorus is to your lawn.)


When it comes to the ability of your lawn to resist diseases and drought occasions, your lawn grasses get that from the presence of Potassium. The availability of Potassium also makes it possible for your lawn grass to utilize Nitrogen when it is available.


Lawn grasses are green, from various lectures through elementary and high school, we understand that chlorophyll production makes that greenery happen. Nitrogen is that particular nutrient that boosts the ability of your lawn to carry out photosynthesis which makes your grass green. What is lawn grass if it is not green.

Organic and Synthetic Fertilizers

Fertilizers can be organic or synthetic. Organic fertilizers are rich in organic plants, such as kelp, blood meal, and so on; they are eco-friendly and are known for giving a great outcome. Due to the organic nature of the fertilizer, it is released slowly into the lawn grass, and grasses can avoid over-fertilizing.

On the other hand, synthetic fertilizers are pretty popular these days and are known to be among the best in the market. They are not as expensive as their organic counterparts and act relatively quickly. The nutrients are available in an exact ratio, so one nutrient is not necessarily overriding another one.

Forms of Fertilizers

Fertilizers are also available in different forms; they can be granular or liquid. Granular lawn fertilizers can be applied during the dry season and do not require frequent application. The liquid fertilizers can be applied using a spray bottle or sprinkler and more frequently than the granular fertilizers. The lawn grass absorbs the liquid fertilizers quickly and acts on them relatively fast.

Frequently Asked Questions (FAQs)

Questions on the hows and whens are carefully answered here to help further you choose lawn fertilizers. We have seen the products we can make selections from, and we also need to have more knowledge about other things that aid the application of fertilizers.

Which is better, liquid or granular lawn fertilizer?

One of the most significant arguments of lawn owners is using either granular or liquid fertilizers. Both forms of fertilizers serve the same functions and perform their unique purposes.

Granular fertilizers usually require a spreader for their applications and mostly have Nitrogen slow-release features. Due to this slow-release feature of granular fertilizers, nutrients from the fertilizers are absorbed slowly by the plants. Still, they have a longer-lasting effect on your plants than liquid fertilizers. Most granular fertilizers have a high percentage of salt, which causes your plant’s roots to be hot. One other significant benefit of granular fertilizers is that they are relatively cheaper than most liquid fertilizers. Different brands of granular fertilizers have distinct nutrient formulations. Some granular fertilizers, due to their content, have some smells that most users do not welcome.

Liquid fertilizers are hugely known; on the other hand, for their ease of use, most come in bottles that also have hose-ends that act as sprayers. Users can mix other liquid fertilizer forms in the tank for easier spreading. The primary good thing about liquid fertilizers is how the plants quickly absorb them and their effects. However, the quick actions of liquid fertilizers make it not to stay too long in your soil and would require frequent application. There are, however, other brands of liquid fertilizers that have the slow-release nitrogen feature. Unlike the granular fertilizers, they do not have a high level of salt content, and most liquid fertilizers brand all have identical formulations in their containers.

Both fertilizers are reasonable and work for different purposes to pick them based on our requirements.

When should I put fertilizer on my lawn?

Due to the adverse effects of wrong fertilizers applications, it is crucial to know the best time to apply them. The best time to add fertilizers is the times when the grasses are actively growing. And the stage of active growth is predominantly based on the type of grass and your growing zone. The first step is to identify the type of grass that can be a cool-season type of grass, warm-season, or grasses with a combination of both cool and warm.

The best times to fertilize cool-season grasses are during spring and fall; you fertilize them lightly and heavily during fall. The actively growing period of warm-season grasses is during summer and late spring; it is best to fertilize these grasses in spring when they are turning green.

With this knowledge of what type of grass you have, you can fertilize when it is best and bring you the best results.

What if it rains after I fertilize?

Most lawn owners get terrified and worry about it raining right after applying fertilizer to their plants. It would interest you to know that rain after you fertilize is not exactly a big problem; it is in most cases a good thing. Especially in cases when you use a granular fertilizer which most times take time to be absorbed by the plant, rain can help you break them down faster and allows them to have a stronghold in the soil. Water helps to activate your fertilizer, so is not something to cause worry. However, if you live in areas with heavy rains, using liquid fertilizers could be a better option as they absorb into the plants quickly. Thus, avoiding cases of having fertilizers washed away.

What is the best ratio for lawn fertilizer?

The best fertilizers contain macronutrients in specific proportions that helps to nourish your grass and keep it green and lush. The NPK ratio of lawn fertilizer is something one must be mindful of as it shows the effectiveness level of the fertilizer. Nitrogen is a macronutrient that is essentially the most of the three essential others: Phosphorus and Potassium. The best fertilizers ratio is the ones whose nitrogen level is significantly 3 or 4 times more than the phosphorus level. The percentage of the fertilizer to choose bases on the soil type and needs of the soil. A soil PH test is conductible to ascertain the nutrient deficiency of the lawn, which would aid the NPK ratio of the fertilizer to choose for your lawn grass.

Which fertilizer would green up a lawn the fastest?

Lawns look beautiful and are a pride when they are green, thick, and rich. Being green takes the lead as the foremost priority of fertilizing a lawn. The nitrogen content in fertilizers is a big reason for the greenery abilities of grass. When buying fertilizer to make your grass green, you should go for brands with a good nitrogen ratio. In addition to Nitrogen, some fertilizers add Iron as a component which boosts the greenery feature. Fertilizers with extremely low or zero Phosphorus are a great choice, and Phosphorus are needed majorly for roots that grasses do not need.

The Scotts brand of fertilizer is trusted among lawn owners and is designed specially for green and thick grasses. The all-in-one fertilizer has an NPK of 32-0-4, which reflects the richness in Nitrogen.

Should I fertilize or kill weeds first?

Weeds are highly unwanted plants that, in most cases, thrive on the nutrients for wanted plants. While we look to maintain a healthy-looking lawn grass, we could face the growth and intrusion of weeds. Lawn owners are focused on fertilizing their grass to improve its appearance and, at the same get rid of these weeds. It is advisable to kill the weeds first before applying fertilizers; it is possible using safe herbicides that would not affect your grass in any way.
