Benefits of Using Liquid Fertilizer

Using a liquid lawn fertilizer instead of a granular fertilizer offers a number of benefits.

First of all, liquid fertilizers are easy to use. Most products go directly onto the soil where they will be absorbed by lawn grasses. By contrast, granular fertilizers must be spread evenly over the surface of your yard and then watered in using a hose or automatic sprinkler system.

Nutrient Application

Liquid lawn fertilizers make it easy to apply the necessary nutrients to your yard. The soil around grass plants can become depleted as a result of rainfall and irrigation, as well as environmental runoff from the air and surrounding areas.

Most liquid fertilizers contain nitrogen, phosphorous, and potassium (NPK) which are used by all lawn types to promote healthy green growth during the summer months. Maintaining these levels is especially important for lawns located in regions prone to hot summers.

High Liquid Concentrate

Liquid lawn fertilizers come in concentrate forms, making them more cost-effective than the bagged variety. They also are easier to store, saving space in your garden shed or garage.

Fast Acting Feed

Liquid lawn fertilizers are also fast-acting, so you can improve your yard’s appearance within a couple of days. The exact amount of time necessary will vary depending on the product used and the region where it is applied.

Immediate Bioavailability

In addition to being fast-acting, the nutrients in liquid lawn fertilizer are also readily available. This means that your lawn will have access to all the necessary nutrients within a matter of hours, instead of the days or weeks it takes granular fertilizers to do their job.

Even Distribution

Since liquid lawn fertilizers are applied in a spray form, they are naturally spread more evenly than granular versions. Also, since grass plants can absorb nutrients from all sides, liquid fertilizers pack more of a punch, penetrating both the leaves and roots of the plant.

Blends With Other Fertilizers

Since liquid lawn fertilizers can be absorbed by the leaves of the plant, they mix well with other fertilizers. Liquid fertilizer can be applied to the lawn for immediate results immediately after applying granular fertilizers. Your grass will drink up the liquid fertilizer quickly, and the granular fertilizer will continue to feed for an extended period of time.

Disadvantages of Liquid Lawn Fertilizer

While there are many advantages to using liquid lawn fertilizer, it also comes with a few disadvantages as well.

Requires Several Applications Through The Season

While liquid lawn fertilizer is fast-acting, it also requires a number of applications throughout the season for best results. This can become costly, especially if you have a very large yard or if your lawn is in bad shape.

For this reason, many people prefer to use liquid fertilizer on their problem areas while using granular fertilizer on larger swaths of land.

Expensive Compared to Granular Options

Liquid lawn fertilizer combined with granular fertilizer can pack a powerful punch on your lawn, but using only liquid lawn fertilizer can become quite costly.

This is especially true in regions where it is hot and dry throughout much of the summer.

Liquid fertilizers can also be found for less expensive prices if you know where to look, but you must compare different brands and product offerings to ensure the N-P-K ratio is suitable for your lawn.

Short-Lived Results

As we mentioned earlier, liquid lawn fertilizers are fast-acting but don’t deliver long-term results. For this reason, many people use these fertilizers as part of an ongoing regimen to help maintain the health and appearance of their lawn.

Liquid Lawn Fertilizer Vs Granular

Now that we have discussed the advantages and disadvantages of liquid lawn fertilizer, let’s take a look at how it compares to its granular counterparts.

While both types of fertilizers can deliver positive results, granular options tend to be less expensive and offer long-term benefits.

However, liquid lawn fertilizer also tends to have a more immediate effect on the appearance of your lawn. So if you want to give your lawn a quick pick-me-up before hosting a Barbecue liquid is the way to go.

In our opinion, the best option is to use the two fertilizers together. A liquid to give the grass a quick boost and a granular to save you time when it comes to extended feeding.

How to Choose the Best Liquid Lawn Fertilizer for Your Lawn

When it comes to choosing the best liquid lawn fertilizer for your lawn, you will need to consider a few factors.

Do You Need Instant Results?

If instant results are what you are looking for, you will want to look for liquid fertilizers that are higher in the N-P-K ratio.

Extremely dry climates can be especially challenging since lawns need more water to uptake nutrients, but high humidity climates don’t deliver enough moisture to the grass. For this reason, it is best to choose a fertilizer with an even balance between the N-P-K ratio.

Does Your Lawn Have Special Needs?

While liquid lawn fertilizer is best for general feeding, you can also choose a liquid that takes into account your lawn’s special needs. For example, if your grass contains high levels of magnesium then you should opt for a liquid fertilizer that has a higher concentration of this nutrient.

What Is the Size of Your Lawn?

Depending on the size of your lawn, you will need to take into account how much fertilizer you will need. Because liquid lawn fertilizers are so effective at delivering nutrients, it is common for people to over-fertilize their lawns.

For this reason, it is best to take an area measurement of your yard and calculate the area (in square feet), then choose a fertilizer that gives you enough N-P-K for your lawn.

Do You Have the Necessary Equipment for Liquid Application?

Some liquid lawn fertilizers attach directly to your garden hose while others require you to mix them into a large tank and then siphon the fertilizer out.

It is important to consider your options and understand if you have the necessary equipment for liquid lawn fertilizer application before choosing a product.

Do You Have an Insect or Weed Problem?

If you need to address weeds or other pests, you will want to choose a liquid weed and feed fertilizer. This type of fertilizer is also beneficial if your grass is prone to insect infestations, and it will kill the bugs and weeds without harming your healthy lawn.

How to Apply Liquid Nitrogen Fertilizer To Your Lawn?

When applying liquid nitrogen fertilizer to your lawn, you first need to attach the hose to your fertilizer tank.

Next, you will want to look at the product’s label and select an attachment for your garden hose that is compatible with the product’s specifications. You should also take into account how close or far apart you want the fertilizer drizzles to be, which largely depends on the size of your lawn.

Once you’ve selected the attachment, open the fertilizer tank and make sure that your hose is turned off. Now you can attach the spray nozzle to your garden hose, turn the water on to a light stream, and begin applying fertilizer. For best results, walk in long straight lines across your lawn (keeping it as straight as possible), but make sure you overlap each line by 50 percent.

When to Apply Liquid Lawn Fertilizer?

Liquid lawn fertilizer should be applied in the early morning or late evening hours when it will have time to be absorbed by the grass. Applying liquid fertilizer too late in the day will cause it to evaporate causing damage to your lawn.

How Much Liquid Lawn Fertilizer Should You Apply?

Choosing how much liquid fertilizer to apply is largely dependent on your lawn’s size. As a general rule, you should only apply the recommended amount of fertilizer for your lawn size.

To find what that amount is, take an area measurement of your lawn in square feet and multiply it by the fertilizer’s manufacturer-recommended application rate.

For example, if you have a 15′ x 20′ yard (225 sq ft) and the manufacturer recommends applying .5 lbs per 1,000 sq ft then you will want to apply roughly 11 lbs of fertilizer to your lawn.

Soil Testing 

Soil Testing is another way to know exactly how much liquid lawn fertilizer you need. Soil testing kits are available for around $20 at home improvement stores, garden centers, and other retailers. These tests will help you determine the pH level of your soil and how much fertilizer it requires in order to reach a certain nutrient level.

If your lawn’s soil has a low pH reading (it is too acidic), you can add lime to the soil. If your lawn’s soil has a high pH reading (it is too alkaline), you can add sulfur to the soil to lower it.

How Long Does My Liquid Lawn Fertilizer Last?

Most liquid lawn fertilizers last around one month or until it rains. Be sure to check the product’s label as there may be a different shelf life for each type of fertilizer product.

How many times a year should I fertilize my lawn?

In the majority of cases, it is best to fertilize your lawn once a month from May through September. In hotter climates, this may need to be adjusted accordingly since grass will require more water and less fertilizer.

No matter how you choose to apply liquid fertilizer, make sure you apply it at the recommended frequency for your area’s grass type. As a general rule, you should fertilize your lawn every 1-2 months from April to September.

During the winter, you will want to stop fertilizing your lawn. In colder climates, apply one last fertilizer treatment in August so that your lawn can get a jump start on growth during warmer weather.

Fertilizers With Weed and Insect Control

Some liquid lawn fertilizers do double duty by offering weed and insect control. These fertilizers are referred to as weed and feeds.

Weed and feed products can be a great way to simplify your lawn care routine and make your fertilization process more efficient. The downside, however, is that these products are often more expensive than standard liquid fertilizers.

Using Weed and Feed as Part of Lawn Care

Read the product’s label to determine whether or not it has weed and insect control as well as how much coverage you will get out of one bottle.

Typically, weed and feed products will last around three weeks to one month. Just as with regular liquid fertilizers, be sure to apply weed and feed at the recommended frequency for your lawn’s grass type.

Liquid Lawn Fertilizer FAQs
