The grass is always greener for people who use liquid fertilizer for lawns.

But how do you know if the fertilizer should be a one-time application or an ongoing treatment regime?

Liquid fertilizer is an easy way to boost your lawn's nutrients, but it can be costly if you use it all the time. So how do you know when to use liquid fertilizer and when not to?

Before we answer that, we must understand what liquid fertilizers are and how they work. Read on!


What is a liquid fertilizer?

Liquid fertilizers are an easy way to give your lawn a quick boost of nutrients.

They are an excellent choice for lawns needing extra nutrients. These products are easy to apply and offer quick results.

Liquid fertilizers are often sold as pre-mixed solutions that you can use right out of the bottle or jug. Some are designed for use on specific types of grasses, while others are suitable for any type of lawn.

Liquid fertilizers are a great option for homeowners who want to do their lawn care. They're easy to use and don't require much effort.

They can also be applied by anyone with basic gardening knowledge, which makes them perfect for DIYers.


Is liquid fertilizer better than granular fertilizer?

Two types of fertilizer, granular fertilizer  and liquid fertilizer

The answer depends on your lawn, but liquid fertilizer is generally better than granular fertilizer. Here are some of the reasons why:

  • Liquid fertilizers dissolve quickly. They can be applied to the lawn and absorbed immediately. This makes them very efficient for homeowners who want quick results.
  • Liquid fertilizers are water-soluble. This makes them ideal for homeowners who don’t want to spend time mixing granular fertilizer and applying with a hose or sprinkler system.
  • Liquid fertilizers can be applied as needed. If you have a small yard that doesn't need much fertilizer, liquid is ideal because it's easy to measure and apply.
  • Liquid fertilizers are less likely to burn your lawn than granular products. Granular products can clump together when they hit the ground, leaving large patches of unirrigated soil behind. This is especially problematic in dry areas where water conservation is essential.
  • Liquid fertilizers are more likely to be absorbed by the soil. They're less likely to clump together or leave dry patches behind. This is especially important in areas that experience droughts or periods of high heat.


How to apply liquid fertilizer to your lawn?

There are many ways to apply liquid fertilizer, but the most effective application method is using your battery-powered sprayer. If you have an automatic sprinkler system, you can add the fertilizer directly to the water supply.

Here's how to apply liquid fertilizer using a battery-powered sprayer:

1. Be sure the sprayer is clean and free of debris. Remove the lid from your sprayer and pour it into a bucket or other container.

2. Fill your battery-powered sprayer with water until it reaches about half full.

3. Add the recommended amount of liquid fertilizer to the mix (usually on the side of the container).

For best results, we recommend using any one of the PetraTools Battery-powered Sprayers for a more even application.


Tips for Using Liquid Fertilizer for Lawns

A well fertilized, beautiful and healthy lawn

Liquid fertilizer is best for lawns that have been recently seeded or have newly laid sod.

1. Be sure the grass has a chance to take root and establish itself before applying liquid fertilizer, which can burn and kill young plants.

2. Apply at least once a month from April through September, especially if you live in an area with hot summers, sandy soil, or drought conditions.

3. Use a slow-release fertilizer for lawns with established grass. This fertilizer lasts longer and works more slowly, so it's best to use it in cooler months when there is less activity on the soil surface—such as during winter snowfall or after rainfall.

4. Look for a liquid fertilizer safe for all grass types.

5. Look for a fertilizer that contains the amount nitrogen, phosphorus, and potassium (NPK) that your lawn needs. This trio of nutrients makes up most commercial fertilizers.

6. Get a fertilizer that contains humic acid and other organic matter. These ingredients help the soil better retain water and nutrients, making liquid fertilizers with these additives the perfect choice if you live in an area with sandy soil or drought conditions.

7. Look for a fertilizer free of heavy metals, salts, and other contaminants.

Also, read the product label carefully to ensure you're getting what you think you're getting—and nothing more than that!


How long does liquid fertilizer last on lawns?

It depends on the type of fertilizer you use and how much you apply.

If you're using a slow-release or time-released fertilizer, it will last about three months after application.

If you're using a quick-release fertilizer, then it will only last for about one month before needing to be reapplied.

Liquid lawn fertilizers generally last a little longer than granular fertilizers, because they are more water-soluble.

This means they leach into the soil much faster, and don't just sit on top of your lawn.


How often should you fertilize your lawn with liquid fertilizer?

A good rule of thumb is to fertilize your lawn every two weeks during the growing season.

It's best to apply fertilizer in the early morning or late evening when temperatures are cool, and humidity is low. This will help prevent damage to young seedlings and grass plants.

What to look for when choosing the best liquid fertilizer for lawns?

The best liquid fertilizer for lawns will have the right balance of nutrients and will be safe for your grass.

It's also essential to choose a product designed specifically for lawns rather than one intended for gardens or other plants.

Some manufacturers combine fertilizer with other ingredients such as weed killer or insecticide. These can harm your grass, so it's best to avoid them if possible.
