Best Lawn Fertilizers – Buyer’s Lawn Care Guide

Fertilizer is a quick way to give your lawn a much-needed boost to help you have gorgeous grass all year round. However, there are several buying considerations you have to keep in mind when you start shopping for the best lawn fertilizers. Along with our reviews that allow you to compare products, this short buyer’s guide will highlight all of the important aspects you need to consider.

Best Lawn Fertilizer 1 Grass
Carefully choosing lawn fertilizers will ensure that your grass has all of the nutrients it needs to put down strong roots and turn a lush green color. 

Choose a Type

One of the first things you’ll notice when you start looking at the best lawn fertilizers is that it comes in two main types. There is a granular type and a liquid type. They both have good and not-so-good points associated with them. Picking one helps you knock out undesirable fertilizers right away.

  • Granular – Granular fertilizer comes in water-soluble or quick-release formats. Quick-release granular fertilizer will last three or four weeks before you need to reapply it. Water-soluble granular fertilizer will last up to three months. Granular fertilizer goes on your lawn with a spreader, and it’s an easy way to ensure you get even coverage each time you apply it.
  • Liquid – If you’re after a very fast-acting fertilizer, liquid is the way to go. They’re convenient, and you usually buy them in a concentrate form. You hook the concentrate up to a hose sprayer and cover your yard. The plants can absorb liquid fertilizer through the roots and leaves, and this means you can see results quicker. However, you have to reapply it every two or three weeks.

Organic or Synthetic

Depending on your preferences, the best lawn fertilizers can be either synthetic or organic. Synthetic is more powerful because it can contain stronger ingredients, but organic is usually considered to be much safer.


Organic fertilizer can go on your lawn, in your flower beds, and on your garden. It’s safe to use directly around your pets and family, and they can usually go on the yard as soon as you apply it. Since they have all-natural ingredients, it can take organic fertilizers longer to start working than synthetic ones. However, they have great long-term effects because they’re eco-friendly. They usually require fewer applications as well. This type of fertilizer is usually less expensive, and it’s more forgiving if you put too much on your lawn.


Synthetic fertilizer is very fast-acting, and it works well if you have a short amount of time to green up your lawn. If you’re on a budget, there are very cheap options available. If you want a stronger formula, this is usually the best lawn fertilizer type to choose. It can kill insects and weeds while improving your yard’s health. They have chemicals, and they contain an exact formula with the nutrients your lawn needs to grow and thrive. However, these chemicals can be harmful if they get around your pets and kids. So, you have to use them carefully.

Best Lawn Fertilizer 2 Type
Things like the weather, type of soil, and the time of year will dictate what is the best lawn fertilizer for your needs. It changes as the year goes on, and you want to stay on top of it to give your grass all of the nutrients it needs.

Nutrient Value

It’s a good idea to pay close attention to the nutrient content of your fertilizer. These are the numbers on the bag commonly referred to as the NPK ratio. The NPK stands for nitrogen, phosphorus, and potassium. They’ll be listed as ##-#-#. So, if a fertilizer has 10-05-5, you know the nitrogen, phosphorus, and potassium levels in the formula. Pay close attention to this number because it gives you a good indication on which nutrient levels will green up your lawn.

Application Process

The best lawn fertilizers have an application process you have to follow to get the best results. If you choose organic fertilizers, they’re more forgiving and will still give you good results if you apply too much. Synthetic fertilizers have specific application requirements that can result in burning your grass if you’re not careful. One way to apply the fertilizer is to use a spreader and walk over your yard. You’ll have to water it in after you apply it. The second application process is using a liquid fertilizer with your hose and spray it over your yard. Some fertilizers tell you to avoid walking on it for a few hours after you apply it, and others allow you to walk on it right away.

Grass Type

There are northern and southern grasses. A lot of the best lawn fertilizers are too strong for southern grasses. Should you apply this fertilizer to your southern grass, it can burn or kill it. If the fertilizer you choose has a specific grass it works for, it’ll say right on the bag. If you’re not sure, try to get an all-purpose fertilizer. You can also look for an organic fertilizer over a synthetic one.

Best Lawn Fertilizer 3 Grass Types

There are dozens of types of grasses, shrubs, and trees that won’t work well with all types of fertilizer. Northern grasses are generally more hardy than Southern grasses, and the fertilizer can create burned patches if you choose the wrong one. 

Alternatives to Traditional Fertilizers

If you’re still not sure what you want with the best lawn fertilizer, you can try a few alternatives. These are natural things you can pick up at your local garden store. However, they’re relatively slow-acting. Slow release fertilizer avoids burning your roots. Additionally, you won’t see any huge changes straight away. You can try:

  • Bone Meal – Bone meal is a byproduct of the meat packing industry. It has phosphorus and calcium in the formula, and this can give your lawn a boost.
  • Blood Meal Blood meal is another leftover from the meat packing industry. To get it, blood meal goes through a drying and steaming process, and it has high phosphorus levels.
  • Peat Moss – Peat moss is something you commonly mix into the soil when you plant trees or shrubs because it lightens up heavy clay-like soils and aerates it If you have sandy soil, peat moss adds weight to prevent it from leaching nutrients out.
  • Fish Emulsion – Fish emulsion is what’s left over from the fish processing industry. It’s organic, nontoxic, and very mild. If you have sensitive plants that will burn with traditional fertilizer, this is a great option.
  • Composted Manure – You can toss composted manure into your compost pile to give it a boost, and it works to condition the soil.
  • Compost – If you need to improve your soil, compost is a great all-around fertilizer option. It contains everything from plant remains to waste like egg shells or leftover food.

Best Lawn Fertilizer 4 Compost

Compost and organic fertilizers are slow release options, but they’re a good option if you’re not sure which fertilizer you need. Avoid the weed and feed options.

Whichever fertilizer is the best lawn fertilizer for your needs, it’s important that you take your time and compare lawn care products. This will ensure that you get the best product for your needs. Pay close attention to the type of grass the fertilizer works with because some aren’t suitable for southern grasses. Take your time, make your pick, and enjoy green grass all season long.
