How to choose your lawn fertilizer

#1 - The type of grass

Knowing what type of grass is planted in your yard can help you choose the right fertilizer for your lawn. That's because grasses come in warm- and cool-season varieties. And a warm-season grass that thrives in a southern state needs different amounts of nutrients than a cool-season grass that grows better in the north and vice versa.

#2 - The soil properties

Your soil has one of the most important effects on your fertilizer needs. It is generally recommended to perform a soil test to determine what nutrients your soil is lacking and the pH level. These simple tests give you a detailed breakdown of your lawn's soil by taking a sample and mailing it to a lab.

#3 - The type of fertilizer

It's important to consider the pros and cons of each type of fertilizer when choosing the right fertilizer for your lawn. Often, the best choice for a lawn is a combination of fast-acting inorganic fertilizers and slow, steady nutrients from an organic fertilizer. Nevertheless, you need to check the pros and cons of these organic and inorganic fertilizers.

#4 - The recommended time to use the lawn fertilizer

As there are different types of grass, different types of fertilizers and different seasons. You also have to consider the right time to apply your fertilizer. That's why on the fertilizer packages you will find indications about the ideal time to apply them. On these directions you will see cool season, warm season, etc.

#5 - The fertilizer application instructions

The way you fertilize your lawn depends greatly on the type of fertilizer you use and the size of your garden. There are several types of lawn fertilizer applicators that spread an even layer of fertilizer on your lawn. All application directions are usually listed on the fertilizer labels, which you should read carefully to help or enlighten you in your tasks.

When and how to apply lawn fertilizer?

Applying lawn fertilizer is an important lawn care chore. Properly fertilized lawns are healthier, out-compete weeds and recover from stress more easily than unfertilized lawns. But how and when to apply that fertilizer is pretty much everyone's dilemma.

When to fertilize? That's the question. Fertilizing your lawn is done every season, but you have to take into account your type of lawn. If your lawn is at the beginning of its active growth period, it is necessary to apply lawn fertilizer once or twice a year and that is more than enough. This is a good time to apply fertilizer because it is when the grass is starting to grow and is greener. For cool season grasses, spring and fall are the peak growth periods. For warm season grasses, which usually grow in the south, you can fertilize in late spring or early summer and again in late summer.

Caution!

Never fertilize during droughts. Lawns naturally go dormant during droughts and do not need fertilizer because they are not actively growing.

How to apply fertilizer? Another good question. Fertilizer should be applied to dry grass with a spreader or other tools and watered in afterwards. If you are using organic fertilizer, don't worry about applying enough of it, as it is not dangerous if you have exceeded the required dose. However, if you use chemical fertilizer, it is necessary to read the dosage prescribed on the label.

The different types of lawn fertilizer

Starter lawn fertilizer

This type of fertilizer promotes the growth of the lawn, as it has a high nitrogen content. Its use is recommended after seeding, because it is quickly absorbed by the plants, but with a short term effectiveness. By this, the fertilizer helps the roots of the grass to anchor in the soil to give a green and healthy lawn. This type of fertilizer should be applied every 6 to 8 weeks during the first season that the grass will grow.

Slow release lawn fertilizer

Fertilizers of this type have a short to medium term effectiveness (about 10 weeks). It is a good choice of fertilizer if you want your lawn to grow faster and denser. It is very convenient to use. Made of granules, it diffuses nutrients into the soil over a long period of time, without the gardener having to come back to it.

Synthetic lawn fertilizers or Organic lawn fertilizers?

Synthetic fertilizers for lawns

Synthetic fertilizers are the standard product traditionally used in commercial lawn care programs to prevent weeds and disease, and to help grass grow green and healthy. Synthetic fertilizers have been used for years on lawns, and they typically involve up to six applications of product throughout the season that covers the lawn with weeds, diseases and pest control. An emerald green lawn is the hallmark of synthetic fertilizers or at least what the companies selling these products promote.

Organic fertilizers for lawns

Organic fertilizers are made from ingredients found in nature and not produced in a laboratory. Quality organic fertilizers are made from bionutrients and act as probiotics that improve the soil's ability to digest fertilizer and absorb nutrients. Not all organic fertilizers are created equal.

Verdict

Both organic and synthetic lawn fertilizers provide life, health and greenness to your lawn. However, organic fertilizers are more likely to preserve your soil longer and provide better grass health. So, for the sake of the environment, it's best to opt for organic fertilizers.

Benefits of using lawn fertilizer

Landscaping a commercial property often requires significant investments. Specifically, your lawn, which is why it is important to fertilize it and keep it in good condition. For this, lawn fertilizer is essential because:

1- It allows the lawn to produce more oxygen:

We all like to breathe fresh and pure air. Having a lush green lawn can help produce more oxygen. In addition to that, a healthy grass helps to keep the area fresh and pure.

2- It allows the grass to protect the properties of the soil:

When plants, specifically grass grows, they absorb nutrients from the soil to keep them alive. At the same time, when the roots cling to the soil, they hold the soil and prevent soil runoff. So when you use fertilizer, the grass is more alive than ever and holds the soil even more. In addition to this, it will replenish the nutrients ensuring that your lawn is healthy and lush. Thus, using fertilizer is an excellent lawn care solution.

3- It makes your lawn more resistant to disease:

Your lawn needs fertilizer as much as it needs water and sunlight. It needs essential nutrients such as nitrate, potassium and phosphorus to thrive and survive. When your plants and turf receive the right nutrients, they are well protected from disease, develop better stress tolerance and are less prone to disease.

4- It allows for improved overall turf growth:

Sometimes you may find that the grass grows lush and healthy in one area, but is thin and sparse in another. This is mainly due to lack of nutrients. The soil may not have evenly distributed nutrients, which is why it is helpful to fertilize using the best lawn fertilizers. This will not only ensure better health for your garden, but will also ensure uniform growth.

5- It provides better pest resistance:

A healthy and well-fertilized lawn is more resistant to pest damage. Proper fertilization ensures that your garden is thick, vibrant and healthy, making it difficult for pests and insects to settle in. Even if your lawn has been affected by pests, disease or other external factors, following a regular fertilization program can ensure a quick recovery.

Tips

Mow your lawn only when it's dry

Dry grass blades stand upright and are less likely to clump when mowed. Whenever possible, mow the lawn when it is dry, as wet grass is harder to mow and is more likely to clump, which can make cutting the lawn take longer. Wet grass can slow down your blades and your lawn mower will not be able to cut at its optimum speed. As grass builds up in the deck, the blades slow down, leading the mower to tear rather than cut the grass.

Add fertilizer to your lawn care routine

To achieve that "grass is greener on the other side of the fence" look, you'll also need to add fertilizer to your lawn care routine. Fertilizing a lawn is an easy do-it-yourself project for homeowners, the only supplies you'll need are a lawn spreader and a high quality fertilizer that meets the requirements of your grass variety. There are two types of spreaders, a drip spreader and a broadcast spreader. Drip spreaders are best for small lawns and broadcast spreaders are ideal for large areas.

Don't forget to dethatch your lawn

Thatch, or the buildup of organic debris between the grass blades and roots can cause dead spots in the lawn and open spaces for weeds to grow. Inspect the lawn for a one-inch layer of thatch. Use a thatch rake or electric dethatcher to remove the thatch. Afterward, the lawn will look terrible, but it will recover in about three to four weeks.

Allow your grass to breathe a little

Sometimes after heavy rains, the cold has solidified the soil under your lawn, making it difficult for water to pass through. Using a garden fork, go around your lawn and poke holes about 1-2 inches deep, about a foot apart. This will help break up the soil a bit. This allows your grass to breathe a little.

Apply your fertilizer in the right place

Keep as much fertilizer on your lawn as possible. If excess fertilizer ends up in your walkways, driveways, or even on the sidewalks, sweep it back into its bag or sweep it back into your lawn. Fertilizer left on hard surfaces can be dumped into streams or other water bodies, or into storm drains that lead to the same areas. Protect the water by keeping the fertilizer in its place. If your fertilizer does not contain herbicides or insecticides, you can fertilize your shrubs and other plants while you fertilize your lawn.
