Organic fertilizer has a lot of benefits for both you and your lawn.

The main benefit of using organic soil is it adds organic matter to the soil and naturally increases nutrient exchange. There are billions of microorganisms in the soil that are a key part of the process and they love to eat organic fertilizer.

When the soil is healthy, it’s able to maintain better moisture levels and attracts a bigger earthworm population. Earthworms are the easiest and most effective way to naturally improve aeration and drainage plus their waste is full of nutrients that plants love.

One of the best reasons to use organic fertilizer is because it lasts a long time. Since organic material takes longer to break down, these fertilizers last for months and remain in the soil even with watering or heavy rain.

Types of organic lawn fertilizer

There are three different types of best organic lawn fertilizer. Each has a different makeup and adds different nutrients and minerals to the soil. The three types are:

Plant-based: Plant-based fertilizers don’t last as long as other organic options but they’re generally the best way to condition the soil. One of the major benefits of a plant-based fertilizer is they can be very effective at helping dry soils hold onto water.

Plant-based fertilizers often use bases of alfalfa meal, compost, cottonseed meal, legumes, and molasses.

Animal-based: These fertilizers include things like bone meal, blood meal, and manure. They add a lot of nitrogen to the soil and are great for the beginning of planting season or when you first seed your lawn.

Mineral based: An example of organic mineral-based fertilizer is calcium or Epsom salts which can add necessary nutrients to the soil while also changing the pH.

Sometimes, this is necessary for optimal growth and a mineral-based organic fertilizer is a great way to achieve it.

Organic Vs Chemical Fertilizer - Which works better?

Both organic and chemical lawn fertilizers give you results but they’re by no means equal.

Here are some of the differences to keep in mind while when determining what’s best for your lawn.

Application: The most common form of organic fertilizer is pellets. Application is generally pretty easy but can take a while. One big plus is that applying too much organic fertilizer does not harm your plants.

Chemical fertilizer most commonly comes in liquid form. It’s easy to apply but you have to be very careful not to use too much because it can quickly burn your lawn and cause brown spots.

Nutrients: Organic products have all the nutrients your lawn needs but the amount of each can fluctuate. That said, they do contain a lot of the macronutrients that your soil also needs.

While chemical fertilizers have precise amounts of essential nutrients, macronutrients are lacking. There’s also a danger that nutrients can build up in the soil over time and run-off when watering or during heavy rain.

Nutrient Release: Nutrients are released slowly with an organic fertilizer at a rate that plants can absorb effectively. Because of this, it requires fewer applications and won’t lead to overgrowth.

Synthetic fertilizers provide a quick burst of nutrients and generally offer a short term solution.

Grass grows quickly and needs to be mowed more frequently. Since the nutrients are released quickly, more frequent applications are needed.

Soil: There’s no question that organic fertilizer is better for soil. It gives the natural microorganisms and bacteria the food they need to help create a well-balanced ecosystem ideal for plant growth.

Chemical fertilizers don’t do anything beneficial for the soil. In fact, the can actually decrease fertility in the long run.


Using organic grass fertilizer is a great choice for the long-term health of your lawn. It provides a large amount of organic matter to the soil that worm and microbe populations thrive on. It leads to the slow release of nutrients over a long period of time, and good texture, drainage, and aeration of the soil.

And because of the time the nutrients are released over, you don’t have to worry so much about overdoing it when you apply it. So you won’t damage your lawn.

Our favourite choice of the best organic lawn fertilizer is Espoma EOFW30 Organic Fall Fertilizer. It comes in easy to use granules, using a source of extended release nitrogen, and with no unpleasant odour due to not using animal parts or manures.
