Keeping your lawn lush and green takes some work, but the right fertilizer can make a huge difference. Liquid lawn fertilizers are a popular choice these days because they’re easy to apply and deliver key nutrients like nitrogen, phosphorus, and potassium right where your grass needs them.
With a sprayer, you can apply these fertilizers evenly and save time compared to other methods. When picking one, it’s worth thinking about your grass type, soil condition, climate, and the fertilizer's concentration—too much can do more harm than good.

Plus, the fact that it works on a variety of grass types means you don’t have to worry about whether it’s compatible with your lawn.
Of course, there are a few downsides to keep in mind. Some hard-to-control weeds may require a repeat application, so you may need to be patient if you have a particularly stubborn weed problem. Additionally, you can’t use this product on or around shrubs, trees, or ornamental plantings, so be sure to read the label carefully before applying. Finally, you’ll need to avoid watering the treated area for 48 hours after application to ensure the weed-killing material doesn’t get washed away.

Buying Guide
Picking the right liquid lawn fertilizer can make a big difference for your grass, and there are a few things to think about before deciding. Here's what to keep in mind:
Nutrient Balance
Check the NPK ratio (nitrogen, phosphorus, potassium) on the label to make sure it suits your lawn’s needs. For example, if your soil already has plenty of phosphorus, go for a formula with less of it.
Application Method
Decide how you’ll apply the fertilizer. Hose-end sprayers are super convenient for smaller lawns, while tank sprayers are better for covering larger areas. Choose the one that fits your lawn size and your comfort level.
Coverage
Make sure the product you pick is designed to cover your entire lawn. If you’re unsure of your lawn's size, take a quick measurement before buying to avoid running out mid-application.
Price
Quality matters, but so does your budget. Compare a few options to find one that gives you great results without costing a fortune.
Frequently Asked Questions
Is liquid fertilizer better for lawns than granular?
Liquid fertilizer is better for lawns than granular because it is easier to apply and provides more even coverage. Liquid fertilizers also have a faster absorption rate, which means your lawn will receive nutrients more quickly. Granular fertilizers, on the other hand, can be unevenly distributed and require water to activate, which can lead to runoff and waste.
What liquid lawn fertilizer won’t burn the grass?
The Simple Lawn Solutions 3-18-18 Liquid Fertilizer is a great option that won’t burn your grass. It is gentle enough to use on all grass types and contains a blend of essential nutrients, including nitrogen, phosphorus, and potassium, as well as seaweed extract and fish hydrolysate.
