The 9-0-2 formula has a high level of nitrogen to help your lawn grow quickly. The potassium will help the roots grow strong, so you'll have a thick, green lawn. This fertilizer can also help repair thinning lawns.

The company advertises that just 3 applications each year are enough to provide your lawn with all the nutrients it needs. This is because each application provides a slow release of nutrients that lasts up to 8 weeks. The results are also noticeable quite quickly, with visible results in 3-5 days.

However, there are some drawbacks to using this fertilizer. One common complaint is the smell. If you don't like the smell of animal waste, then you will not like this fertilizer. It is made from blood meal and feather meal, which both have a strong smell. But the smell goes away quickly once it is on the ground and watered in.

The fertilizer is tricky to spread because it is a powder and it also has chunks the size of a pea. This means it sticks to the sides of the spreader and is applied inconsistently to the ground.

Buying Guide:

There are many different organic lawn fertilizers on the market. They all have a different balance of nutrients and a different composition.

There are a few things you need to think about when choosing the best organic lawn fertilizer:

Types Of Fertilizer

Depending on what they're composed of and what they do for your soil, you may categorize natural fertilizers into a variety of different types:

  • Animal-based

There are many different types of fertilizers. Some, like those made from bone meal, feather meal, blood meal, and manure, release nutrients quickly. However, over-application of manure can burn plant roots.

Some animals are attracted to the smell of blood meal. If you don't want animals coming to your yard, it's not a good idea to put blood meal there.

  • Plant-based

Some people think that plant-based fertilizers, such as compost, are more valuable for conditioning your soil than for adding nutrients. This is because they often have low NPK values.

One of the main benefits of using compost is that it helps dry soil retain water. This is important for plants, as they will be able to uptake the water more easily. Apart from compost, there are other plant-based fertilizers that you can use, such as kelp seaweed, alfalfa meal, and cottonseed meal.

  • Treated Sewage Sludge

This is sewage material that has been composted and treated until it is considered to be biologically safe.

Dried manure is often used for commercial purposes. But it's not recommended to use when growing vegetables in your backyard. The USDA has ruled against using dried manure in the US for organic food production because of toxic metal accumulation, hormones, pharmaceuticals, and other unwanted things.

Nutrients

When choosing the best organic lawn fertilizer, pay attention to the NPK value. This will tell you how much Nitrogen (N), Phosphorus (P), and Potassium (K) is in the fertilizer.

The numbers on the bag of fertilizer tell you how much of each element is in the product. An organic fertilizer showing 8-2-2 consists of 8% Nitrogen, 0% Phosphorus, and 2% Potassium. In a 20 lb bag of fertilizer, this would mean 1.6 lbs of nitrogen, 0.4 lbs of phosphorus, and 0.4 lbs of potassium.

Nitrogen, phosphorus, and potassium are important for plant growth. Grass needs these nutrients in the greatest quantities to grow well.

Your soil probably has some of the things your grass needs to grow. But you can also add fertilizer to help make up for any nutrients that are missing from the soil.

For grass, it is usually important to have plenty of nitrogen in your fertilizer. This will help the grass grow well. However, for new lawns, phosphorus and potassium can be more important. This will help the lawn grow stronger roots.

These are the benefits of using them on your grass:

Nitrogen:

  • Essential for proper growth.
  • Needed for developing a strong green color. Deficiency in nitrogen will result in chlorosis producing grass with a yellow-green color.

Phosphorus:

  • Important for the development of strong root systems.
  • A lack of phosphorus can result in slow growth.

Potassium:

  • Protects from cold, disease, and drought.
  • Deficiency can slow the rate of growth.
  • It also plays a part in phosphorus and nitrogen having their full effects.

Organic fertilizers usually have low NPK values. This means that they have less of the main nutrients that plants need to grow- nitrogen, phosphorus, and potassium. This is because organic fertilizers are made from natural ingredients, which contain a variety of minerals and nutrients.

There are two ways to find out if your soil is deficient in any nutrients. You can either test the soil yourself or get a local co-operative testing office to do it for you.

Now, if you have looked at the products listed above, you might be wondering:

One of the reasons it is discouraged to use phosphorus in lawn fertilizers is because it can dissolve into water. This can pollute waterways, such as rivers and lakes.

Phosphorus is important for new lawns, but it's not as important to put it in your fertilizer when you are taking care of an established lawn unless your soil is deficient.

Is Organic Lawn Care Better?

Organic fertilizer usually doesn't have as high of an NPK value as chemical fertilizers, but there are some benefits to using it.

Organic fertilizers add organic matter to your soil, which is good for the growth of grass. Micro-organisms thrive on this material and produce a healthy nutrient-rich environment for your grass to grow in.

Chemical fertilizers can kill the microorganisms that are living in the soil. They also harm other life in the soil, like earthworms, bacteria, and fungi. Organic fertilizer makes soil richer over time. This makes the soil better in many ways, like composition, texture, drainage, and root growth.

Organic materials need to be broken down by organisms in the soil to release their nutrients slowly. This is good for your grass because it means that you do not need to fertilize as often. It also means that the fertilizer will continue working over a period of weeks or months, even if it rains a lot. So although organic lawn fertilizer can sometimes be more expensive, you will end up using less of it, which can balance out the cost.

Another great thing about using paper is that it's biodegradable and doesn't harm animals that enter your garden. Plus, it's safer for both people and pets!

Using Organic Lawn Fertilizer

Organic fertilizer contains nutrients that are good for your grass. However, it takes a while for the grass to use these nutrients. This is because the organic material has to be broken down first.

It is important to plan ahead when you are going to fertilize your lawn. Do not wait until the lawn looks unhealthy. You can buy organic fertilizer in pellets, granules, meal, or liquid form. Granules and pellets are the easiest to apply evenly. Liquid fertilizer is easy to spray, but it can be harder to get even coverage. Put granules in a spreader and apply them at a steady rate as you walk around your lawn.

There are liquid fertilizers that can give you quicker results. Some products include beneficial microbes. This is a good choice if your soil has become sterile from using chemicals in the past. The microbes help to produce healthy soil and revive your grass. If your lawn is already healthy, then you might not need to go to the extra expense.

Here are some tips on how to use it:

You can also spread organic fertilizers by hand. If you do this, you might want to get a pair of gloves. Organic fertilizers are not as dangerous as chemical fertilizers, so you don't have to worry about using too much. However, using the same setting on your spreader as you would for chemical fertilizer will probably work just fine.

After you apply the fertilizer, it's a good idea to mow your grass. This will help the fertilizer get down to the soil. You can also leave the grass clippings on the lawn to help them decompose and add nutrients back to the soil.

After you apply the fertilizer, water the lawn thoroughly. But don't water it so much that the water runs off. It's safe for pets and children to use the area after you've applied the fertilizer. But be aware that dogs might be attracted to products with blood or bone meal in them. So it can be a good idea to keep your dog away from the area until after you've watered it in. If your dog seems interested, watch it carefully.

The best time to apply organic fertilizer for grass is in the fall. This conditions the soil nicely ahead of spring growth. You can also add it in the spring, but because organic fertilizer needs microorganisms to break it down, warmer soil is often required. This means it can take a while for visible results.

You can also apply the best organic lawn fertilizer in the summer. Some brands make separate organic fertilizers that are specially formulated for the spring, summer, and fall.

Final Thoughts

Organic grass fertilizer is good for the long-term health of your lawn. It helps to add organic matter to the soil, which makes it a good place for worms and microorganisms to live. This can help release nutrients slowly over time and keep the soil healthy.

You don't have to worry about overdoing it when you use this fertilizer. That means you won't damage your lawn.
