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?

This one works very well, but we felt that they could make it odorless. The smell is strong and pungent, and you will not be able to walk in your yard for the first few days. The smell then diminishes and disappears over time. So, if you are planning a garden party, do not apply just before it.

Buying Guide For The Best Organic Lawn Fertilizer

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 upon consuming it.

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

3. 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.

4. 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.

5. Coverage

Check for the area it can cover before purchasing 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.

Conclusion

As our gardens continue to be a crucial space for relaxation, enjoyment, and a connection to nature, providing proper nutrition to our lawns has become an essential part of preserving their beauty and health. Organic lawn fertilizers are not only eco-friendly and safe for our families and pets, but also nourish the soil and encourage the growth of lush green grass.
