The 4 Best Lawn Fertilizers (Organic & Synthetic) 2021

For many of us maintaining a great looking lawn can be a struggle. You might look over at your neighbors grass with envy and wonder what you can do to make yours look just as nice. Nobody wants ugly brown patches scattered around their yard and they don’t want weeds or crabgrass either. One of the best ways to rid yourself of these problems is to make sure your lawn gets all of the nutrients it needs throughout the growing season and that starts by choosing the right fertilizer.

Below you’ll find our recommendations for the best choices around, but first, we’ll take a quick look at the benefits of organic fertilizers vs synthetic options.

The Organic Choice

As you’ve probably already guessed, organic fertilizers are made from all-natural ingredients such as seaweed, kelp and alfalfa. They feed your lawn much-needed nutrients, but it takes longer for your grass to see the benefits than it does if you choose the synthetic option.

If you want a great lawn as quickly as possible, organic is not the best way to do it. If you’re trying to balance what’s best for the environment, your children and your pets with a desire for a healthy law then organic is the perfect solution.

Why Synthetic Fertilizers Are More Popular?

While environmental concerns are a major concern for many homeowners, synthetic fertilizers are still the more popular choice. There are a couple of main reasons for this – they’re usually less expensive and you get positive results more quickly.

There’s a lot of science that goes into making great fertilizers and the experts have included a lot of ingredients that result in a fast-growing healthy lawn, but they can also harm the environment around them and they can be a potential hazard for your kids and your pets.

If you do go the synthetic route, be sure to keep your children and pets off your lawn while you do.

The Best Lawn Fertilizers 2021:

1. Simple Lawn Solutions Complete Lawn Food

Why It’s Great For Your Lawn:

There’s a good reason that Simple Lawn Solutions have called this one the Complete Lawn Food – it’s full of ingredients both organic and synthetic that provide all of the nutrients that your lawn needs to grow healthy and thick.

A common term in the fertilizer world is the NPK ratio, which refers to the mix of nitrogen, phosphorus and potassium in the product. This one has a ratio of 16-4-8, which is ideal for helping the grass grow. It can be used on all types of grass and it’s relatively safe to use compared to many of its competitors.

Potential Concerns:

There isn’t a whole lot that we don’t like about Complete Lawn Food. Like any fertilizer, you do have to be careful not to use too much of it and it may be a bit more expensive than some of its competitors. It’s also usually sold in smaller 32-ounce containers which won’t cover large lawns so you may have to buy a few containers if you have a bigger yard.

  • An ideal NPK ratio.
  • Combines organic and synthetic ingredients.
  • Works on all types of grass.
  • Relatively safe.
  • A little more expensive.
  • Usually sold in smaller quantities.

A Great Choice:

The Simple Lawn Solutions Complete Lawn Food is the perfect product for dealing with problem areas of your lawn. While you can use it on your entire lawn, that’s not the best use of this product. It can get expensive if you’re using this on a large lawn, but for mallet lawns or problem areas of a larger lawn, it’s ideal.

2. Scotts Turf Builder Weed & Feed

It’s specially formulated to attack dandelions and clovers while thickening your lawn with nutrients at the same time. It uses something Scotts calls WeedGrip technology and it’s highly expensive.

Potential Concerns:

As the label on the package says keeps this product away from your children and your pets too. This product is highly effective because it’s synthesized to attack weeds and it uses some potentially harmful ingredients to accomplish this task. You also don’t want to overuse this product as it will burn your lawn if you’re not careful with it.

  • Highly effective weed killer.
  • WeedGrip technology.
  • Fast-acting.

Scotts Turf Builder is a great choice if you have a lawn full of weeds or a couple of areas you’re trying to rid yourself of dandelions. It does contain strong ingredients that may be harmful to small children or pets so it should be used in moderation. As long as you’re careful when using this product we highly recommend it.
