A good lawn fertilizer should not only transform your garden but also make the soil healthier without putting your pets at risk.

If you are a DIY gardening enthusiast, you will know how important it is to provide the right nutrient to the soil. It should get organic matter, which will add the necessary microbes and nutrition while not sticking to the ground. That’s not all; water drainage is essential, and the soil should be well aerated for that.

That’s precisely why we detest chemical fertilizers – they often burn the grass. But, looking for an organic alternative is not easy with so many options in the market.

Hence, we decided to make it easier for you by curating this list of the 13 best organic lawn fertilizers. We have also mentioned the pros and cons of each to make it easier for you to decide.

So, without further ado, grab a cup of your favorite beverage and dive in!

  1. Dr. Earth Super Natural Lawn 9-0-5 715

If you are looking for quick results, the Dr. Earth Super Natural Lawn 9-0-5 715 will be an excellent choice. We were very impressed to see how quickly it made a difference to the soil. We recommend using it every 3 months to make sure that your lawn stays healthy and well-hydrated.

No products found.

Why Did We Like It?

We loved how beneficial it is to promote a hardy root system, as it helps them grow stronger and latch on to the soil. This, in turn, ensures that the plants are not adversely affected or uprooted even during major hurricanes and storms. We were very happy to see the leaves of our plants shining after applying the fertilizer.

Furthermore, the smell could be slightly unpleasant, but that is because of the pack’s large fish content. It is made of fish bone meal, feather meal, fish meal, seaweed, calcium sulfate, alfalfa meal, mycorrhizae, and some additional microbes. All of this is extremely healthy for the soil, and the nutrient level rises on application. Hence, you will be able to grow several items on the lawn.

Another great feature is that it will control thatch from accumulating in one place. It digests thatch, leading to a clean surface free from debris. Also, it prevents Mycorrhiza from growing, and the soil stays healthy and hydrated.

What Could’ve Been Better?

We felt that the product could be considered expensive if used for big lawns and yards. Bags of 18 pounds will not suffice for long in large spaces, and you will have to buy them often. But if you can afford to spend more, then we will surely recommend this product.

Pros
  • Makes the soil fertile enough to plant shrubs and trees
  • Can feed up to 3 months
  • Controls thatch from accumulating
  • Makes the roots stronger
Cons
  • Expensive

We applied it every 8 weeks throughout the growing season on our lawn, and it worked out well. Although you can begin applying it any time of the year, it is best to begin in early spring. That way, you can repeat the application in mid-summer, which promotes good grass growth.

The different types of grass that grow well with this fertilizer are Tall Fescue, Kentucky Bluegrass, Centipede grass, Perennial Ryegrass, St. Augustine grass, and Bermuda grass. Furthermore, they grow well while reducing the growth of weeds.

Plus, you can cover an area of 5,000 square feet, making it very economical. This will do the job perfectly while ensuring you can cover lawns of all sizes.

What Could’ve Been Better?

One major drawback is that it attracts a lot of flies. This could be problematic and usually lasts for the first few days after you apply the fertilizer. We would recommend not letting the kids play in the lawn for a few days after application. Let the fertilizer settle down, and the flies will go away.

Pros
  • No fishy odor
  • Can cover an area of 5,000 square feet
  • Deep root development
  • Non-burning formula used

The item supplied our grass with a lot of highly-digestible carbon, which helped in the growth of microbes. This enhanced the level of good bacteria making the soil fertile and rich.

Because it does not contain sewage or manure, there is no smell. We were very happy with this as our kids could play in the yard the same day.

Another amazing benefit is that there is no risk of burning the turf even if you apply more than necessary. It is suitable for all weather conditions, and you can apply it throughout the year. There is no toxic element in it, and hence, you do not have to worry about the fertilizer mixing with a pond or well in the backyard.

What Could’ve Been Better?

While you will love the results, this product takes more time to work than its peers. In a month, we found that our grass is greener and thicker. But you will not see immediate results, and you will need to wait at least 3 weeks to see a difference. Be patient with it, and it will work well.

Pros
  • Stimulates healthy growth of plants
  • Can be applied in cold and hot weather
  • No issues with burning

This contains a mixture of pasteurized poultry manure, feather meal, and gypsum, which together make for a great mix. It comes in a 30 lbs pack, which is sufficient for a 5,000 square feet area.

A great fact that we noticed is that the nitrogen is released at a slower pace. It is 2.5 times slower than its peers, which is very beneficial for the soil. This ensures that there is a constant nitrogen supply for the soil. It makes the soil healthy and keeps it like that for weeks.

Secondly, it has calcium in it, which makes the soil healthier. It adds all the necessary ingredients without burning the ground. You can apply it without worrying about burning or promoting excess bacteria growth.

Overall, we found this to be a very efficient product. The 30 lbs pack will last you long in case of a small or a medium-sized lawn.

What Could’ve Been Better?

The one issue we had with this product is that it does not prevent weed from growing. That means you will have to clear the garden often to ensure that there is no weed. This could be problematic for those leading a busy life.

Pros
  • Safe for pets and children
  • Releases nitrogen slowly, ensuring a better spread
  • Last for long
  • Has a great calcium content

Are you wondering how this fertilizer is made? Well, a lot of rich and organic ingredients are fed to earthworms. These then pass through the worm systems and are completely altered physically and chemically. It then results in the formation of super hummus, which is very fertile and works amazingly well for root growth.

Another great advantage is that it improves the structure of the soil. The fertilizer is in the form of tiny round particles that allow for ample aeration. They do not stick to each other and help roots grow faster and become more fibrous. The water retention capacity of the soil also increases, leading to better hydration.

What Could’ve Been Better?

If you are purchasing this pack, ensure that there are no bugs in it. The first pack that we ordered had some bugs, and if they are scattered on the soil, they will begin to breed. Hence, check the mix and only then pour it on the soil.

  • Non-toxic and safe to be used around pets
  • Promotes fibrous root growth
  • Can be easily absorbed

What Could’ve Been Better?

While we mentioned a number of plants that are compatible with this product, there are others that will not accept this, and you might not see any changes.

Pros
  • Contains nitrogen, potassium, and phosphorus

  • Slow-Release Gardener's Supply All-Purpose Fertilizer Is...
  • Conditions soil for more vigorous root growth and improved...
  • NPK: 5-5-5

Why Did We Like It?

One problem that often occurs with fertilizers is that it gets absorbed by the soil and the excess washes off when you water your plants. This means that the effect lasts only for a short while, and you will have to reapply again frequently. With this product, you can rest assured that the formula is going to work for a long time.

This is because of the slow-releasing feature that ensures that it dissolves with the soil over time. It will keep releasing important nutrients in the soil and hence will ensure that your plants stay healthy for a long while.

Also, we were happy to see how well the roots developed over time. If you are using it for new plants, this will ensure that they grow well and the roots grip the soil in a very short time.

What Could’ve Been Better?

Pros
  • Provides balanced nutrition
  • Promotes better water penetration
  • Good for root development
  • Perfect for all seasons
Cons

What Could’ve Been Better?

The only problem we noticed with this product is that you have to mix it well with water before application.

Overall, we were very impressed by the efficiency, and an 8-ounce bag will provide you with benefits for 6 months up to a year depending on the number of plants.

What Could’ve Been Better?

What Could’ve Been Better?

Pros
  • Safe for humans, wildlife, and pets
  • Easy to apply
  • Available in granulated form
  • Works quickly

Hence, you are going to love this odorless formula. It will ensure that a lush green turf replaces your patchy or bare lawn.

Many fertilizers need time to be soaked in, and hence you cannot venture around the lawn within an hour or 2 of applying. But here, because of its organic and 100% natural formula, you do not have to restrict yourself, pets, and kids at all. They can immediately play on the lawn after application and will face no health issues.

Also, this 10-0-2 formula does not contain phosphorus. This meets the Town & Municipality Regulations that restrict the use of phosphorus. Hence, you can use it around water bodies easily.

What Could’ve Been Better?

The product works really well, but we would have been happier if the price would be lesser. It is on the expensive side, and if you have a large lawn, then it can exceed your budget. However, if you have the liberty to spend a little more, then we would recommend this product.

Pros
  • Promotes strong root systems
  • Odorless formula
  • No phosphorus
  • Free from harsh chemicals
Cons

  1. Natural Alternative Early Spring 25005

Are you looking for a product that can be used near water bodies? The Natural Alternative Early Spring 25005 will be an incredible choice. It can promote root development and ensure that grass, as well as plants, grow well. The slow-releasing formula would feed the soil slowly and hence lasts for a long time.

No products found.

Why Did We Like It?

First of all, we were very happy to see the high level of nitrogen content in them. It also has biosolids and microbes that promote the growth of plants and grass. The level of biosolids matches the standards of EPA and hence are perfect for gardening enthusiasts.

If you have barren patches of land, this will bring back a smooth green surface. The grass turned out to be thicker, and the leaves would shine. We were very happy to see them grow to be so healthy.

Adding on, it is perfect for use beside water bodies like ponds, rivers, and seas. This is because it does not contain phosphorus. Phosphorus often flows into water bodies if used beside it and then causes the growth of algae in it. That depletes the oxygen levels and can cause fishes to die. So, it is better to use this phosphorus-free product if you have a pond.

What Could’ve Been Better?

While we were very happy with the green coverage, it took awhile for the product to work. Do not be disappointed if you see that there is no development initially. Give it a few weeks, and you will see the garden transform. Also, ensure that you water it well for the perfect coverage.

Pros
  • Filled with rich organic microbes
  • Lasts for a long time
  • Works well around water bodies
  • Iron and sulfur promotes root development
Cons
  • It takes time to show results

Organic Lawn Fertilizer Buyer’s Guide

Now that you have gone through the top lawn fertilizers, you must have a clear idea as to what to expect. There are different kinds of mixes, and they come in different amounts. Now it can still be very confusing to choose one. To help you out, we have curated this buyer’s guide, which will help you make a choice. Read on to know all about it.

  1. Material Used

One of the major considerations is the kind of materials that have been used for making the fertilizer. Now generally there are 2 kinds of materials. One mix contains bone meals and feathers, which work wonderfully for the soil.

There are other ingredients derived from animal manure and fishes, which are very nutritious for the soil. But on the other hand, these smell a lot and could be a problem if you plan on hosting a party in your backyard soon.

Also, these are blood meals and hence can attract animals. Make sure you do not have a lot of rodents or other unwanted visitors before applying it.

That brings us to the next type of mix, which contains plant remains, seaweed, alfalfa meal,cottonseed meal, and microbes. These usually do not have any smell while providing all kinds of nutrients to the soil. If the smell is a problem, this is a great alternative.

Sometimes, some products may have a toxic element that may not work with pets and kids. So, ensure that your product is free of all toxins so that your pet does not fall sick on consuming it.

  1. Use Of Sewage Sludge

Earthworms, fungi, and bacteria which are part of sewage sludge are positive additions to the soil, and they can improve the texture and composition. Roots grow better, and they are able to send food upwards to the leaves in an efficient manner thanks to the lots of minerals and nutrients.

You must have noticed that some of the fertilizers have a large number of biosolids. These bio-solids are nothing but sewage wastes. The wastes are collected, composted, and then treated. It is known to be biologically safe, but we would suggest not to use it for growing food.

 If you have a vegetable or a fruit garden, then stay away from fertilizers with biosolids. They may have metal accumulation or hormones which should not enter edibles.

  1. Presence of Phosphorus

Phosphorus is also beneficial and helps in promoting root and plant growth. It is that ingredient that makes plants grow faster. But it also has a major problem. We would advise not to use phosphorus if you have a water body beside it.

This is because it tends to mix with the water and cause algae to grow in it. Algae reduces the oxygen level of the water and makes it unsuitable for living organisms like fishes.

So, if your garden needs a dose of phosphorus, then apply it very carefully. Ensure that you do not add too much water to the garden so that none of it flows into the pond or river beside.

  1. Granules v/s Liquid

Fertilizers are generally available in 2 forms, liquid and granular. The most common type is the granular one, which needs to be mixed with water and then applied. Some organic products can directly be applied to the soil, and you can sprinkle water over it. Liquid ones usually come in concentrated form. You will have to mix it with water and then sprinkle it over the entire area.

  1. Coverage

Check for the area it can cover before purchasing a fertilizer. Most packs can cover an area of 3,000-5,000 square feet at one time. If it covers a very less area, then you will have to buy it frequently, and that will be expensive. Hence, make a note of it beforehand.

Verdict

Organic fertilizers might have less NPK value, but they are full of nutrients and essential microbes. So, they make a healthy medium to add these microorganisms to the soil, thereby making it more healthy.

Now, before we sign off, let us do a quick recap of our favorites. The Dr. Earth Super Natural Lawn 9-0-5 715 is an excellent option when it comes to seeing results quickly. It works immediately, and you will see a transformed lawn within days.

The Safer Brand Ringer Lawn Restore SA9333, on the other hand, is a brilliant choice if you want an excellent solution for soil that has become dry or barren. And if you are looking for a cost-effective item, the Espoma EOSR30 Organic Summer Revitalizer will work well.

With this, we have come to the end of our guide. Choose carefully, and you will have a beautiful garden to boast of.

Happy shopping!
