Benefits of Using Liquid Fertilizer for Lawn
When it comes to fertilizer, there are a lot of reasons to choose a liquid product over a granular option. Let’s take a look at some of the benefits of using a liquid fertilizer.
Because liquid fertilizer is concentrated, you get a lot of use out of a small bottle. This saves you money and is a lot easier to carry around than a comparable amount of granular fertilizer.
Another benefit to a highly concentrated form of fertilizer is you can dilute it to suit your needs. While each product is different, most have a higher starter application with lower maintenance applications throughout the season.
Easy to Apply
A lot of these products attach directly to a garden hose for easy application. Others are designed to be added directly to irrigation systems and some require a separate sprayer. However it’s applied, liquid fertilizer gives a uniform, even coverage that granular fertilizer does not.
Liquid fertilizer is also a much better way to cover large areas of land. Because it applies evenly, you can rest assured that one side of your lawn will get just as much fertilizer as the other.
Liquid fertilizers deliver nutrients to both the roots and the surface of the grass so they’re absorbed quickly. Granular fertilizer, on the other hand, does not provide anything to leaves of grass and can take time to take effect in the soil.
Some of these most important nutrients for lawns have to be carried to the root and the only way to do that is by watering them in. Since liquid fertilizers are mixed with water, you can save time by feeding your lawn and giving it the water it needs at the same time.

When to Apply Liquid Lawn Fertilizer?
When you should apply your liquid fertilizer depends on the type you’re using. Usually, you can find detailed instructions on the side of the bottle. That said, there are some general guidelines to keep in mind.
If you’re using a fertilizer that is applied once a year, apply it around Labor Day. That’s when your lawn will need it the most and it will soak up all the nutrients. This also helps build up a reserve in the soil to help it get through the cold fall and winter ahead.
If you want to apply your fertilizer twice a year, add a second application in October to give your lawn a little extra food for the winter.
You may also choose to do a third application in the early spring and a fourth mid-summer if necessary. If you’re applying fertilizer all year round, it’s better to give a smaller dose in the spring unless you notice slow growth or discoloration.
Some of the products we chose for our recommendations are specifically for spring and summer. In this case, the first application is usually given in the spring with smaller doses applied every few weeks throughout the summer.
Take caution when applying liquid chemical fertilizer at the peak of summer when it’s really hot and humid. It can actually harm your lawn. Luckily, organic options are safe to use in this weather. We included several organic options on our list.
As far as what time of day to apply fertilizer, the most important thing is to avoid the hottest part of the day. Applying fertilizer when the weather is too hot and humid can damage the grass. In the summer, early morning applications are best.
Finally, it’s best to fertilize your lawn when the ground is moist. This will help it get absorbed more quickly. It’s also less likely to burn or harm your grass than if you apply it to dry ground.
How Much Liquid Lawn Fertilizer to Apply?
Again, it varies. The most important factors to determine how much fertilizer is the size of your lawn and how much nitrogen it needs throughout the year.
Knowing the right amount of fertilizer to apply is really important. Too little and you won’t get the results you’re looking for. Too little and you won’t get the effect you’re looking for; too much and you can end up seriously damaging your lawn.
The best way to find out how much fertilizer you need to apply to your lawn is to get a soil test. Fertilizers are classified by the amount of nitrogen, phosphorus, or potassium they contain. This is expressed as NPK. A soil test can tell you how much of each you need which will help you choose the right fertilizer.
Testing your soil isn’t as difficult as you might think. Most major home and garden centers sell easy-to-use kits that measure all three of the major elements in liquid grass fertilizers. Once you know what your soil needs, you can choose a fertilizer that suits your lawn’s needs.
How Much to Apply
Once you know that you’re using the right fertilizer, follow the directions on the side of the bottle. These fertilizers usually have pretty clear instructions as to how much you should use for initial applications as well as maintenance doses throughout the season.
How to Apply Liquid Fertilizer to Lawn?
There are a few ways to apply liquid fertilizer, both of which are pretty easy to do. Again, each product is a little different so make sure you read the directions for the product you choose and follow them carefully. Here’s an overview of how they work.
The most common way to apply liquid fertilizer is to spray it onto your lawn. This can be done in a few different ways.
Some of the products we chose some in bottles that are designed to fit right onto a garden hose. First, shake the bottle well to make sure the contents are mixed well before attaching it to the hose.
Once the hose is attached securely, turn on the water. Then, turn the sprayer to the “on” position. Fertilizers that come with their own spray nozzle are generally calibrated so the liquid is automatically diluted to the right concentration but, again, read the directions on your product to be sure.
Apply the spray in a side-to-side motion being sure to cover the entire area as evenly as possible. Start in the far area of your lawn, making your way back to the spigot so you can turn the water off when you’re done without having to walk through the areas you fertilized.
For the products that don’t come with a spray attachment, you will need to use a sprayer. You can use a hose-end sprayer that works similarly to the method mentioned above. Pump sprayers are another option.
Pump sprayers are large containers that you either carry or wear on your back. Fill the container with the properly diluted fertilizer. Use the handle to add pressure to the container. Then, hold the wand and press the lever or button to release the fertilizer.
With a pump sprayer, work systematically from one side of your lawn to the other, ending close to the door. This way, you won’t have to walk through the freshly fertilized grass when you’re done.
If you have an irrigation system, it’s the perfect way to fertilize your lawn and pretty easy, too. We included one product that is meant to be used in this manner. Exactly how you use it depends on what type of irrigation system you have.
With this type of fertilizer, you can either add it directly to the tank with water or use it with a ProFeeder system. Make sure you follow the instructions carefully and, remember, this type of fertilizer should not be used with sprayers.
To choose the best liquid fertilizer for lawns, it’s very important to make sure you know what your lawn needs. A soil test is the best way to do this. They’re easy to use, inexpensive, and available at most home and garden centers.
Once you know what NPK ratio you need, there are a lot of great options to choose from. We included a nice variety of quality products here to help you find one that will work best for your lawn.
