Understanding the Best Lawn Fertilizers

Lawn fertilizers are made from 3 nutrients and filler. These nutrients are:

Nitrogen (N)

This is a protein apparent in all plants, so it goes without saying that supplementing it would spur grass growth. That’s not all because it helps your lawn to fight off harmful pests. It is one of the nutrients that promote the lavish green color in your lawn.

Phosphorus (P)

This is an ingredient that provides your grass its ability to turn nutrients into growth-material. Fertilizers contain nutrients, but phosphorus allows these nutrients to provide a robust root. For instance, if you have a new lawn and wants to enhance its growth, applying a fertilizer with phosphorus can help you achieve that.

On the other hand, if your lawn has been around for decades, you should avoid fertilizers with phosphorus.

Potassium (K)

Just like nitrogen, potassium is meant to spur the growth of your grass. It is called the “quality nutrient” because it affects your grass shape, color, and size. If you come across a healthy looking lawn, chances are it’s because of potassium.

Additionally, potassium helps your grass to develop resistance to drought and cold.

Complete Package: N-P-K Fertilizers

If your lawn is new, you will probably want to invest in an N-P-K fertilizer. The proportions of these nutrients are shown on the bottle or bag. The bag might show something like “10-6-4” (10 parts N, 6 parts P, and 4 parts K).

10-6-4? How do you read these proportions? Consider a 50 pounds bag of lawn fertilizer and it is marked 10-6-4, this is what it contains:

• 5-pound of nitrogen or 10 percent.
• 3-pound of phosphorus or 6 percent.
• 2-pound of potassium or 4 percent.

Clay or sand will make up the rest of the weight. This helps you to spread out the fertilizer easily.

Other Nutrients for Healthy Grass

Too little or too much acid in the soil is harmful to your lawn. When you test the pH, you will see if it is in the recommended range of 6.5-7.5. If it is below 6.5 (acidic), you should add lime, if it is above 7.5 (alkaline), you should add an acidic fertilizer such as sulfur, ammonium sulfate, or ammonium nitrate.

Types of Lawn Fertilizer

Generally, when you hit the market, you will come across 3 different kinds of lawn fertilizer: water-soluble, granular, and organic.

Organic Fertilizer

Organic type is all-natural and you can easily make it at your home. This is what is commonly known as compost manure.  Organic fertilizer breaks down slowly releasing nutrient back into the soil. The soil then feeds your lawn.

Granular Fertilizer

Granular type of fertilizer comes in time-release formulas and enables you to control when your lawn will be fed.

Water-soluble Fertilizer

Water-soluble type is an instant-release fertilizer, so the results will be instant (about 5 days). This type of fertilizer uses ammonium-based products to help your grass absorb the solution easily.

When you are choosing the best type for your need, ensure that you consider these factors:

• how you intend to apply it,
• how much your grass needs,
• how regularly you will be applying it,
• and how available you are to take care of your lawn.

Considering these four things can help you make an informed decision for your lawn’s specific needs. For instance, if you are around throughout the summer/spring to watch your lawn, the water-soluble type might be the best. On the contrary, if you can’t get time and you won’t be around, the granular type might be the one for your grass.

Also, ensure that you note any other issue that your lawn might be having. Lawn fertilizer can include ingredients that ward off pests or bugs and removes weeds like black clover, crabgrass, and chickweed. You can also get fertilizers with extra ingredients that enhance fast-growth.

Different Types of Grass Require Different Lawn Fertilizers

Knowing the type of grass in your yard can be a critical step in figuring out what types of fertilizer to buy. As a rule of thumb: if you dwell in an area with a hot climate, this area will have warm season grass. These types of grass need between 3-4 pounds of lawn fertilizer for every 1,000 sq. ft. annually.

On the flip-side, colder regionals have what is called cool season grass. This grass requires about 1-2 pounds of fertilizer for every 1,000 sq. ft. annually. It is a sturdier grass that can withstand more, so it requires less lawn fertilizer-care.

Tricks and Tips of Estimating Lawn Fertilizer Needs

The simplest way to estimate the amount of fertilizer required by your grass is to measure your lawn’s surface area. Take a measurement of length and width to compute square footage. Alternatively, you can do a strategic guess, which will be almost as accurate as measuring.

In general, every 8 steps are roughly 10 feet of space. Walk from different sides of your lawn as you take the width and length. You will get an idea of how much area you need to cover. As a visual guide, consider a standard tennis court which measures 36 feet by 78 feet.

For misshaped lawns, you can consider these computations:

Triangle

Determine the width and length of the triangle. Multiply the width by the length and then divide by 2. This answer will be your lawn’s surface area.

Circles

Find the center of your lawn and walk out toward the edge. Multiply 3.14 by this number to get the surface area.

When to Fertilize

The rule of the thumb is to fertilize your lawn as early as possible. You should get the right nutrients to your lawn when it is growing and when it primarily needs them.

One trick you can follow is to check the weather forecast in order to fertilize your grass one day before the rain begins. This is the best way to put down your fertilizer and let the Mother Nature do the rest (the hard work).

If your lawn is grown, fall is the perfect time to fertilize it. The idea behind this timing is to ensure that your fertilization coincides with the cooler temperature and during the wet time of the year – the perfect condition for your grass to absorb the nutrients easily.

The second best season of fertilizing is spring. This is when your lawn is coming back to life and wants food. Applying a quick-release weeding fertilizer can be a good idea since it will starve pests and weeds. It also helps your lawn to develop strong roots – ideal for withstanding harsh weather during the dry season.

Methods of Applying Lawn Fertilizers

Some lawn owners just spread these fertilizers like chicken feed. This is wrong since you will most likely get irregularities in the color of your lawn as the fertilizer starts to work its magic. You should get a fertilizer spreader, which will make the task easier.

However, these tools can make your work even harder if they don’t function easily, you don’t know how they work, or if they aren’t effective.

There are different types of spreaders or applicators out there:

Hand-Held Applicators

They used to work quite well. Sadly, some manufacturers have changed these products, and what used to be a simple, useful tool is now the number one source of frustration. With that said, there are still great applicators out there.

Push-type Spreaders

These types can be a broadcast-style or drop-style wheel spreaders. Each has its lawn depending on the shape and size of the surface you want to apply your fertilizer. The neighboring area might also affect your choice.

A broadcast spreader spreads the fertilizer in a bigger area, and the distance it spreads is influenced by how slow or fast you push it. A drop spreader simply drops the fertilizer to the ground. The only concern with this style is to avoid overlap as you move back and forth, and always close the hopper when you rest.

Whichever brand and model you decide to buy, make sure that the manual is easy to follow and offers all the setting. These machines are calibrated with various size openings, but with no guide, you will be using the machine blindly.

Which ever way you spread your fertilizer, be aware that these fertilizers might stain your brick and concrete, especially if they have iron. Sweep it thoroughly before you water.

Lawn Fertilizers FAQs

Q: Can I store unused lawn fertilizer for use next season?

A: Yes. You can easily store and reuse unused fertilizer as long as it bag is tightly closed and kept in a dry place. If water finds its way into the bag, you will have lumping of the fertilizer, break up these clumps before you place it in your spreader.

Q: How many lawn fertilizer applications should I do during the year?

A: We would recommend you to apply these fertilizers at least two times a year for cool season grasses, one in fall and one in spring. If you decide to do just once per year, do it during fall. For warm season grasses, we would recommend you to do it regularly – during the hot months.

Q: I want to de-thatch my lawn. Is it okay to apply the fertilizer before I dethatch or should I apply it after de-thatching?

A: You should always apply your fertilizer after de-thatching.

Q: What are the 3 numbers on lawn fertilizer bags? What do they mean?

A: These numbers represent the percentage or concentration of 3 nutrients that are required by your grass. For instance, 10-10-10 is read as 10% Nitrogen, 10% Phosphorus, and 10% potassium.
