8 New Best Lawn Fertilizer Reviews in 2019 – A Comprehensive Guide

Wonder why the grass looks greener on the other side? Well, it might be because a good lawn fertilizer is used there. In this article, we will be focusing on the best lawn fertilizers. Not only that, we will be including some important information about these fertilizers along the course of writing this article.

How To Choose The Best Lawn Fertilizer?

There’s a lot of fuss on how to choose the best lawn fertilizer. This is why we have decided to include a guide to help you choose the best fertilizer for grass below.

Numbers

The numbers on your fertilizers are very important as they determine if you will be going home with a good fertilizer or not. Sometimes, you see something like ‘NPK 15-4-8’ and wonder what it means. In simple terms, it is the percentage of nitrogen, phosphorous and potassium in the fertilizer. With an NPK 15-4-8 combination, it means there is a 15% concentration of nitrogen, 4% of phosphorous and 8% of potassium.

In general, the importance of nitrogen is to help make the plants look lush and green. Also, phosphorus helps to strengthen the roots of the plants while potassium helps to fight drought and diseases. In light of this, when selecting a fertilizer for your lawn, make sure you check the NPK combination and ensure you choose the one that suits your needs. However, worthy of note is that phosphorous can contaminate water. So, before making your buying decision, keep a tab on the phosphorous level.

Organic Or Synthetic?

You have a choice of choosing the process which your fertilizer is made. You can either go for synthetic fertilizers or the organic ones. Synthetic fertilizers are made from different processes and they tend to include different minerals and gasses. Often, these fertilizers produce quick results but when applied in the wrong way, they can burn your grass. Besides, synthetic fertilizers can lead to environmental and physical problems if they find their way into the water supply.

Organic fertilizers, on the other hand, are made from living organism waste like manure or blood and bone meal. These fertilizers do not show results as fast as the synthetic ones but they are mostly safe for the environment, animals and people in general. We advise that organic fertilizers should be a priority over synthetic ones. This is because they do not cause harm to the environment.

Types Of Fertilizers For Your Grass

There are different types of fertilizers for different situations, weather and soil type. We will be highlighting all of them below.

Quick Release Fertilizers

Just like the name, quick-release fertilizers are made to provide nutrients to the soil immediately. This is particularly useful for soil with serious nutrient problems. When this is applied, changes in the lawn become visible almost immediately. Besides, you can begin to see the changes in less than 5 days. However, it is important to note that sometimes, this type of fertilizer can lead to burning of the grass. This is why the fertilizer should be used the right way the manufacturers prescribe.

Time Release Fertilizers

The time-release fertilizer works by feeding the lawn nutrients for a stipulated time frame. With this, there is a constant supply of nutrients to the soil and the plant which helps to keep the grass looking lush for a long time. With this fertilizer, all you need is a single application and the plants will continue to enjoy the nutrients till the time expires. Usually, the manufacturers of the fertilizer indicate the time frame for this.

Gradual Release Fertilizer

The gradual release fertilizer is sometimes called the ‘slow release formula’. The way it works is by slowly giving the plants the needed fertilizer at the right time. Besides, this is only possible because the nutrients don’t get drained away into the soil after application. Also, this type of fertilizer doesn’t burn the grass and it is safe to use them at any time of the year.

Starter Fertilizers

Starter fertilizers are good for growing new lawns. Often, this type of fertilizer contains a high level of phosphorous. This is because phosphorus is useful for improving the strength of roots.
