5 Best Lawn Fertilizer for Beautiful Lawns in Spring

With the arrival of spring comes the need to sprinkle a good lawn fertilizer on your lawn. You might be confused about when and what type of fertilizer should you invest in.

Application of the right lawn fertilizer at the right time will give your lawn the essential nutrients to grow it to be beautiful and healthy. We would look at 5 best lawn fertilizer for spring.

What is The Need for Lawn Fertilizers?

Your lawn has many enemies like pests, weather, insects, etc., so keeping it healthy and fresh becomes a challenging task. Lawn fertilizers are a solution to this. But do we actually know why lawn fertilizers are important?

A lawn fertilizer provides all the healthy and important nutrients for the grass to grow in a high-quality soil. Potassium, nitrogen and phosphorus are the three food elements that your lawn needs to be green and fresh.

Not only these elements, but sunshine and water are also required for the grass to thrive. Lawn fertilizers are organic and environmentally friendly. As I have already shared in this post, they provide your lawn the healthy nutrients which helps the grass to grow at a faster rate.

How to Choose the Best Lawn Fertilizer for Spring?

I have often heard my friends complaining about the confusion in choosing the right lawn fertilizer for their lawns.

Hence, another important decision to be made is the choice of your lawn fertilizer to maintain your lawn beautifully. Fertilizers come in different blends of plant nutrients to take care of lawns and to complete other basic needs.

An ideal lawn fertilizer should release the nitrogen slowly into the soil, making sure that its loss to the environment is as little as possible.

Phosphorus is an important element required by the grass to grow, but an excess amount of phosphorus might get washed away into the nearest water bodies and harm them.

Using phosphorus free products is also an option to avoid water pollution. Potassium is important for the grass to make it heat & cold tolerant and also for protecting it from diseases.

If you are choosing a lawn fertilizer, then you should also take the climate conditions into mind as well. You might notice a three-digit number on the packaging of a lawn fertilizer.

This is known as the NPK ratio, which explains the percentage of nitrogen, phosphorus and potassium in a product. Depending on the NPK ratio needed by a lawn, a lawn fertilizer should be chosen.

For example, if an NPK ratio mentioned on a product is 20-0-10, then it signifies 20% nitrogen, 0% phosphorus and 10% potassium.

A lawn fertilizer comes in two different forms – liquid and granular. Choosing the granular lawn option might prove to be a better one for your lawn rather than choosing the liquid one.

A liquid lawn fertilizer might pose a risk to the nearest water bodies, exposing it to harmful chemicals like cadmium and arsenic. Since the liquid lawn fertilizer drains off easily, you might have to apply it more frequently as compared to the granular one.

The only disadvantage of a granular lawn fertilizer is that it takes time to show results.

The Negative Impact of Fertilizers on the Environment

Fertilizers provide all the important nutrients to the grass, but have we ever considered how they are negatively affecting the environment?

Nitrogen is converted into ammonium or nitrate by the microbes in the soil so that it can be used by the plants. This nitrate gets easily released into the environment, hence causing soil acidification.

The released nitrate can penetrate into the groundwater used by humans for domestic purposes, further posing as a threat to their lives.

Cadmium is known to be present in soil in minute amounts. If large amounts of cadmium are released into sandy soils, then it can turn out to be a severe problem for the growth of the grass.

High intake of phosphorus in a fertilizer might result in the accumulation of algae in the nearest water bodies which results in the death of aquatic animals as they are robbed of all the oxygen content in the water bodies.

The effect of lawn fertilizers on humans as well as plants’ health is a controversial topic until now. It is believed that the NPK ratio in the fertilizers damage crops faster than those which are not receiving fertilizers.

If a higher amount of nitrogen is used for green leafy vegetables, moreover if it is eaten raw as a salad, then it might have an adverse effect on the health of humans.

Every lawn might have a different requirement, so it is better to research different fertilizers before choosing one for your lawn.
