1. Organic milorganite fertilizer

Milorganite is an organic nitrogen fertilizer. It contains 4% chelated iron and helps your lawn achieve this rich green color quickly.

Milorganite is one of the oldest fertilizers on the market and consists of heat-dried microbes that have broken down the organic matter in the wastewater. Once they have done their job, they die and leave a layer of cake. This caked material is dried, heated to kill all pathogens, and then crushed into granules that make for a fantastic organic fertilizer.

Milorganite is non-flammable and will not burn your lawn or grass when you use it. The NPK value of 6: 4: 0 means that it has little impact and is unlikely to damage the environment. Plus, you don't have to water it, which saves you time and effort.

Milorganite is environmentally friendly, safe and reliable for decades. For many it is the best lawn fertilizer and I can understand why!


  • It shows quick results

6. Miracle-Gro water soluble lawn feed

I know that a lot of people are not fans of Miracle Gro products. Their NPK ratio is too high for practically all products and they do not feed the soil in addition to the lawn.

Nevertheless, they work surprisingly well when used as directed. They recommend using their hose end sprayer to ensure proper dilution, and they are very specific in terms of the amount of product to be added to the spray glass. If you follow the instructions, the water-soluble Miracle-Gro lawn feed is very easy to apply and results in a lush green carpet of grass.

At 36-0-6, this is the highest NPK option we list today. But remember, it is diluted with water. Once it has passed through the hose sprayer, apply a much lower dose overall. Just be careful not to overdo it as too much can cause burns. It is also recommended to fertilize early in the morning so that the grass can dry during the day.


  • Greens the grass quickly
  • Easy to use when using the company's hose sprayer


  • Can cause burns to the fertilizer if overused

Understand what fertilizer is

Choosing the best lawn fertilizer can be a challenge. We help! Source: Mini D

There are many things that work as fertilizers. Whether synthetic or organic, a fertilizer is essentially a substance that provides your plants with nutrients. As a result, if your plants have the fertility they need in their soil, they are healthier. Healthy plants grow faster, produce higher quality flowers or fruits and are less susceptible to pests and diseases.

The basic nutrients your plants need are nitrogen, phosphorus and potassium. These three resources give your plant almost everything it needs to survive:

  • Nitrogen helps with photosynthesis and also accelerates rapid growth.
  • Phosphorus helps with healthy root development and also helps with flowering and fruiting.
  • Potassium strengthens the stems and supports good root development.

For lawns, we are less concerned with the supply of a large amount of phosphorus, since no flowers or fruits are produced on lawns. Our main interest is nitrogen so that it grows vigorously and stays healthy.

While these primary nutrients are essential for plant development, many others are also consumed. For lawn grass, iron in the form of chelated iron can produce a much deeper green color than the lawn could otherwise produce. And for those of us who are looking for a perfect lawn, that's important!

What kind of grass do you have?

It is important to know which grass you have. If you do not know your lawn type, you cannot select products optimized for this type. In addition, some types of weeds and feeds target certain grasses as weeds. It is not a good thing for your fescue lawn if its fertilizer kills it!

Some types of grass are best suited to a particular climate. For example, many of the grasses with thicker blades can withstand more heat than the types with slim blades. This makes it a great choice for the southern climate. The fine-leaved species can grow faster in cooler climates and return quickly after frost or ice.

As a rule, a product that is only a fertilizer without any weed control can be used on most types of lawn. You still need to have an idea of ​​your lawn's ideal needs to get the best growth, but it's less likely to cause harm.

There are three basic variables that we discuss when we talk about lawn fertilizers.

Organic vs synthetic

Organic fertilizers are developed from naturally occurring sources. These can be other herbal products such as alfalfa flour, waste products such as chicken manure or dead material such as milorganites microbial substance. Many organic substances are safe for animals and children and feed the soil and the grass growing there.

Synthetic fertilizers are chemical mixtures that are produced in the laboratory. Although these contain the same basic nutrients in relation to NPK, they do not come from biological sources, but from laboratories. They are often purer than their organic counterparts and can burn fertilizer if used excessively. Plastics often only target the growing material in a lawn and in no way improve soil quality.

Granular vs Liquid

Granular fertilizers are pebble-like or pelletized fertilizers that can be easily distributed when dry. These only fertilize after wetting and then dissolve to release nutrients into the soil. You can send them by hand or spread them using a spreader. They can be used at any time of the day.

Liquid fertilizers include both water-soluble and pure liquid forms. These are applied with a hose end sprayer, which dilutes the fertilizer and spreads it over the lawn. It is best to apply in the morning so that the excess moisture evaporates during the day.

Quick release vs. Slow release

Slowly releasing fertilizers release nutrients through your lawn over time. They feed much longer because they slowly break down into the soil when watered.

In contrast, a quick fertilizer provides a quick insight into plant nutrition that lasts from a few days to a maximum of a few weeks. After this time, they tend to be washed out of the ground by regular watering.

When should the lawn be fertilized?

Depending on the type of fertilizer used, you may need to fertilize more or less frequently. It's best to read the manufacturer's instructions and apply as suggested.

In principle, all-season fertilizers can be applied at any time of the year. There are seasonal blends that are optimized for a specific season and the needs of your lawn during that time.

How much lawn fertilizer to use

As with fertilization, it depends on what you use. Follow your manufacturer's instructions regarding the amount to be used.

Avoid over-fertilizing your lawn. Too much fertilizer can burn the blades of grass, and the fertilizer can also damage the grass roots system. Fertilizer fire leads to yellow, unsightly spots, which can take some time to grow back. Fertilize your lawn according to the label on your product.

Use lawn fertilizer safely

While most lawn fertilizers are generally recognized as safe, we still recommend some safety precautions when using or storing them.

  • Wear protective gloves when working with lawn fertilizer. Whether it's a liquid fertilizer or a granular one, you don't really need large amounts of it on your skin.
  • Keep lawn fertilizer out of the reach of pets and children. My dogs are absolutely fascinated by organic fertilizers and although it doesn't hurt to eat them, they can get sick if they eat a lot of them. Children just put everything in their mouths, and the blue color of a product like Miracle-Gro is appealing – and really unsafe to eat!
  • Use it according to the manufacturer's instructions. Although you may think that a lot of fertilizer is better than just a little, this is usually not the case. Too much fertilizer can cause your lawn to burn fertilizer. This can damage the roots and yellow the blades. Fertilize your lawn according to the manufacturer's recommendations.
  • Make sure it is in an airtight container. Liquid fertilizer tends to spoil if it does not remain fully sealed. Granular types tend to clump when exposed to moist air. To ensure that your lawn fertilizer is ready to spread over your grass type, an airtight container is best.
