Detailed Buying Guide for Best Lawn Fertilizer for Spring

Types Of Lawn Fertilizer

Organic Fertilizer

As the name describes, an organic lawn fertilizer contains only natural ingredients in its formula. It is healthy for the environment, animals, and humans.

Most gardeners who aim to build a system in the lawn choose this type of grass fertilizer. It creates a perfect natural balance for both your lawn and the soil.

Natural lawn fertilizer can work to provide essential natural nutrients to the plants in your garden so that they can thrive.

During the decomposition of fresh organic elements, all the soil particles in your lawn will bind together and form a good structure.

Not only that, but the organic products also support the production of healthy microbes, which are beneficial for your plants.

Due to the only natural ingredients in the formula, organic fertilizers are more expensive than other types of grass food. However, if you use an organic product, you don’t need to buy extra nutrients or different pesticides for your garden.

Compared to non-organic fertilizer, an all-natural product gives the result slower. But due to the healthy substances in the formula, this type of spring fertilizer is ideal for use in the long term.

Liquid Fertilizer

Liquid fertilizers contain many powerful chemical ingredients. That’s why they can give a good result after a short period.

After applied, the fertilizer can immediately reach the grassroots to form protection. No grass or harmful substance can attack the soils in your garden.

This type of fertilizer usually comes in a spray bottle or an automatic sprinkler (with a sprinkler attachment). You can spread the fertilizing liquid over all surfaces of your lawn with convenience.

If you are low on budget, a liquid lawn fertilizer will be the best option. The great thing is, you can either buy a premixed fertilizer or prepare the mixture from different ingredients by yourself.

Concentration and chemical control are the 2 most important factors to notice when mixing the liquid lawn fertilizer. If you overdo the mixture, the heavy dose of fertilizer may become harmful to your lawn.

Liquid fertilizers contain a lot of chemicals. You need to avoid contacting them directly and keep them far away from your children and pets.

Another drawback is, this chemical fertilizer can be absorbed quickly right after they are applied. Therefore, you have to reapply this product to your lawn frequently.

Granular Fertilizer

Granular fertilizers can remain up to 12 weeks and have a slow decomposition. The gradual decomposition allows the soils in your lawn to receive consistent supplies of nutrients.

This type of fertilizer also contains chemicals in its formula like liquid products do. However, due to its long-lasting, it does not require frequent application.

The granular fertilizer usually appears as coarse powder or pellet. You can spread it across your lawn either using a lawn spreader or by hand.

You can apply the granular fertilizer using 1 of the 2 following techniques:

1. Add the fertilizer in a hole before putting the soil in.

2. Use the fertilizer as a top dressing after filling the soil in the hole.

Although granular fertilizers contain chemicals as ingredients, they stay in a dry form. Hence, there is no issue if you touch them directly.

However, it is still essential to keep them away from your children and pets.

Coverage

A package of fertilizer should be able to cover the entire of your lawn. Before buying a product, make sure that you measure your garden.

Usually, a good fertilizer can deal with 2000 – 4000 square feet. Some high-quality models can even provide extensive coverage of up to 5000 – 6500 square feet.

You should buy a package that is as big as possible for multiple uses.

Ingredients

No matter which type the fertilizer is, it has to contain the 3 following essential nutrients:

When buying a spring lawn fertilizer, you should check the NPK value (NPK ratio) shown above or under the fertilizer label. It tells the percentage proportion of those 3 main ingredients in the product.

For example, a package of spring fertilizer shows a 22-0-4 ratio. This means that the product has 22 percent Nitrogen, 0 percent Phosphorus, and 4 percent Potassium.

The best spring fertilizer should have a high NPK value, especially Nitrogen. Each nutrient in the 3 above have different features:

  • N: Support leaf development and make lawn green
  • P: Support rapid growth of root
  • K: Prevent disease for a stronger and deeper root growth

The best time to fertilize or spray in spring:
