Best Liquid Lawn Fertilizers in 2023 and How To Use Them

To keep your lawn healthy and green, fertilizing can be a good practice, especially if your soil is lacking in nutrients. Agronomy experts at the Perdue University Extension concur that periodic fertilization of an established lawn is important because it keeps the lawn looking good and reduces how much you have to water and control weeds, insects, and disease risks — that saves you money, and is environmentally responsible.

There are many fertilizers available on the market and it can often be a little overwhelming to decide which is the best for your particular lawn needs. 

One option that can yield immediate results is a liquid lawn fertilizer concentrate. These cost-effective products provide systematic, long-term nutrient support for your lawn and most of them are easy to apply while offering iron and other beneficial minerals. 

In this article, we’ve included a detailed user guide to the best liquid lawn fertilizers available no matter what your goal. Plus, our gardening experts have tested 10 of the top sellers from premium brands to help you choose the right one for your lawn care needs.

Benefits of Using Liquid Fertilizer 

There are many valid reasons to choose a liquid fertilizer over a granular formula, especially when you need an easy-to-apply product that will provide fast results and give you an even distribution of nutrients. Here is a rundown of those main benefits to consider when choosing the best liquid lawn fertilizer as well as explaining some of the advantages versus granular products.

Easy To Apply

Most liquid lawn fertilizers have the option to be supplied in a hose end bottle and trigger, giving a fast and clean application. There is no mixing, or weighing out of the product, and no need for fertilizer spreaders. Any type of spray application provides consistent nutrient support in a proportional manner, as the components are sprayed in a blended viscous form. This means, your entire lawn will receive the same amount of fertilizer throughout.  What I mean is…the same ratio of nutrients per sq ft of lawn.

I have tried to illustrate my point below in this diagram. Granular fertilizers are often individual grains of a single nutrient and this can result in the uneven distribution of nutrients, with pockets forming.

Uneven distribution of fertilizer granules

High Liquid Concentrate

Since liquid fertilizers are highly concentrated, you get surprising coverage from a single bottle, with many products delivering over 3,000 sq. ft. from a 32 oz bottle. This gives the added benefit of making the product much easier to carry around the yard when compared to the larger bags of granular fertilizer needed to cover the same lawn area.

Fast Acting Feed

Liquid fertilizers provide nutrients to the roots and surface of the grass immediately so your lawn is able to absorb these nutrients quickly. Granular fertilizers, on the other hand, are designed as slow-release food that can take longer to take effect and require watering or rainfall to distribute the nutrient compounds into the soil. 

Liquid vs Granular Lawn Feeds

Liquid nitrogen fertilizers have gained popularity in recent years, and although there are no real differences between the total amount of nutrients provided by liquid or granular fertilizers, there are other notable differences in application and absorption. So, let’s look at the fundamental benefits of liquid lawn fertilizer vs granular fertilizer.

Liquid Fertilizer


  • Uniform and even application
  • Phosphorus can absorb better in the grass
  • Better for starter lawns
  • Easy to apply
  • Quick-release product


  •  Set up or application process can be expensive
  •  Requires more frequent application 

Granular Alternatives


  •  Easy to store for long periods of time
  •  Slow release product
  •  Efficient for pre-planting


  • May burn plants
  • Harder to apply evenly
  • Certain nutrients can’t be absorbed as efficiently
  • Takes longer to yield results

Choosing The Best Liquid Fertilizer for Grass

When choosing a liquid lawn fertilizer from a range of product options, several factors should be considered to ensure optimal lawn health and growth. Each of these factors matters as they directly influence the effectiveness of the fertilizer and the overall appearance and health of your lawn. So be sure to give them consideration if you want the best possible results.

Grass Type and Climate: Different grass types have specific nutrient requirements, and local climate conditions also affect nutrient uptake. Choose a fertilizer formulated for your grass type (cool-season or warm-season) and consider the climate in your region.

N-P-K Ratio: The nitrogen (N), phosphorus (P), and potassium (K) ratio is critical, as it determines the primary nutrients provided by the fertilizer. Assess your lawn’s specific nutrient needs, either through a soil test or by identifying visible signs of deficiency, and select a product with the appropriate N-P-K ratio.

Application Method: Consider the application equipment you have available (hose-end or backpack sprayer) and your skill level. Ensure the liquid fertilizer is compatible with your equipment and easy to apply evenly to achieve the best results.

Additional Ingredients: Some liquid fertilizers contain added organic components (seaweed, fish emulsion), soil amendments (humic and fulvic acids), or micronutrients. These extras can improve soil health and provide additional benefits, but they may also affect the price of the product.

Environmental Impact: Consider the environmental footprint of the fertilizer. Look for products that are eco-friendly, organic, or made with sustainable ingredients to minimize negative effects on the environment, groundwater, and local ecosystems.

Compatibility With Other Products: If you plan to apply weed control, insecticides, or other lawn treatments, check if the liquid fertilizer can be mixed with these products. This can save time and effort by allowing you to apply multiple products simultaneously.

Cost and Frequency of Application: Liquid fertilizers may require more frequent applications than granular alternatives, which can affect the overall cost and time investment. Compare prices and application recommendations to choose a product that fits your budget and maintenance preferences.

The Best Liquid Lawn Fertilizers Reviewed

Need help to choose the best liquid lawn fertilizer? Our selection criteria include the fertilizer’s compounds, its performance, value for money, and the level of customer satisfaction, taking into account thousands of user reviews across major online platforms. Take a look at our experts’ comprehensive review of the 10 best liquid lawn fertilizer concentrates starting from our top pick:  


  • Covers 3,200 Square Feet
  • The 6-19-0 N-P-K ratio, with a higher phosphorus content, encourages strong root growth, which is crucial for a healthy and resilient lawn.
  • Contains humic and fulvic acids. These organic acids improve soil structure, increase nutrient availability, and promote microbial activity, enhancing overall lawn health and growth.
  • Extreme Grass Growth Lawn Booster can be used on various grass types, making it a suitable choice for diverse lawn conditions and needs.


  • Unlike the more balanced 16-4-8 formula reviewed below, the Extreme Grass Growth Lawn Booster focuses primarily on root development and grass growth, which may not address all lawn nutrient requirements.

I tested the Simple Lawn Solutions Extreme Grass Growth Lawn Booster as part of the trial, however, I have used it many times in the past on my lawn and clients’ lawns.

Firstly, the unique blend of humic and fulvic acids, along with the 6-19-0 N-P-K ratio, proved to be highly effective in promoting root development and overall grass growth. I observed a significant improvement in the lawn’s thickness and appearance within just a few weeks. The liquid formulation allowed for quick absorption of nutrients, resulting in faster, more visible progress.

Another advantage was the ease of application. With a hose-end or backpack sprayer, I achieved even coverage and accurate distribution of the product. The compatibility with other Simple Lawn Solutions products also allowed for the simultaneous application of fertilizers or weed control, which saved time and effort.

However, there were a couple of downsides to the product. The cost of the Extreme Grass Growth Lawn Booster was relatively high compared to other liquid fertilizers on the market. While the premium ingredients and superior results justify the price, it may deter some budget-conscious consumers

This fertilizer delivered impressive results in promoting grass growth and root development. The ease of application and compatibility with other products were significant benefits. Despite the higher cost and lack of some trace minerals, the results were fantastic, so I would recommend this lawn booster to anyone seeking rapid, substantial improvements in their lawn’s thickness and overall appearance.

To apply the fertilizer, simply attach the bottle to your garden hose and it’s ready to go. You can use it on all types of grass.

Customer reviews: users were impressed with the results that were evident within just a day or two after application and rated the product 4.1 out of 5 stars. 


  • Contains a high nitrogen fertilizer and ‘greening agent’ to give your lawn a lush appearance
  • Suitable for all grass types without risk of scorching or burning
  • Just screw your hose into the bottle and spray. Can be used repeatedly.


  • Spray mechanism is not as good as Simple Lawn Solutions bottle

Scotts Liquid Turf Lawn Food is a 2 in 1 product that delivered nutrients across your lawn with its built-in hose pipe attachment. Connect your hose pipe to the bottle, activate the trigger, and essentially water your lawn, whilst fertilizing it. This high nitrogen fertilizer delivers a 29-0-3 nutrient ratio and is designed to be used throughout the season. It also contains a ‘greening agent’ to help give your lawn a fast lush green appearance.

Like most of the products at the top of this short-list, the spray bottles connecting to your hose pipe are just a great time-saving approach to treating your lawn. Scotts Turf Builder is easy to work with, it has a simple on/off lever on top of the bottle that you activate with your thumb to control the water flow.

Cover up to 2,000 sq ft of lawn per 32 fl oz. bottle, although this will depend on the pressure of your hose. Water flow draws out the liquid fertilizer, so the faster the flow, the quicker the fertilizer will be dispersed. Check the latest price on

How to Use: screw your water hose into the back of the bottle and activate the trigger spray. Continue to water your entire lawn. When done you can release the water pressure and unscrew the bottle for use again another day. This product is designed for use throughout the growing season.

Customer reviews: a few years back the sprayer mechanism was not the best, but Scotts appears to have overcome these issues. The results are great with a lush green lawn.


  • Suitable for a variety of grass types, including both cool- and warm-season species.
  • Free from harsh chemicals, making it a safer choice for the environment, pets, and children.
  • The addition of seaweed and fish components provides micronutrients and organic matter, promoting soil health and microbiome activity.


  • Can be more expensive than other brands, especially those without organic components like seaweed and fish.  

I recently trailed Simple Lawn Solutions Advanced 16-4-8 Liquid Fertilizer on my lawn, and overall, I am quite pleased with the results. The liquid formula made it simple to apply using my hose-end sprayer, ensuring even coverage across the entire lawn.

One aspect that truly stood out was the quick absorption of nutrients. I noticed a significant improvement in the color and health of my lawn within a short period, which was quite impressive. The balanced N-P-K ratio of 16-4-8 was suitable for my grass type and seemed to address its nutritional needs effectively. I also liked that this product contains seaweed and fish components, which not only provided additional micronutrients but also supported the overall soil health.

However, there were a few drawbacks. The cost of Simple Lawn Solutions Advanced 16-4-8 was slightly higher than other liquid fertilizers I’ve used in the past. While I understand that the added organic components contribute to the price, it’s still worth considering for budget-conscious consumers. Additionally, I found that the liquid fertilizer required more frequent application to maintain the desired results, which added to the overall cost and effort.

In conclusion, Simple Lawn Solutions Advanced 16-4-8 Liquid Fertilizer delivered remarkable results for my lawn, and the ease of application was a major advantage. While the price and frequency of application were slight drawbacks, the overall benefits make it a product I would recommend to others looking for a quality liquid lawn fertilizer.

How to apply: the highly concentrated formula comes in a ready-to-use bottle, complete with a fertilizer sprayer nozzle. Just connect it to your garden hose for quick and easy application in spring and summer.

The 32-ounce liquid fertilizer works on all grass types with up to 3,200 square feet of coverage! Just be sure to keep your grass watered sufficiently for maximum nutrient absorption. Buy Advanced 16-4-8 online here

Thousands of customers rated this product 4.2 out of 5 stars making it a star buy.   


  • Excellent coverage of up to 16,000 sq feet
  • Suitable for all grass types
  • Long-term improvement


  • Gel-like substances need warming for easy application

Customer reviews: users rated the fertilizer 4.3 out of 5, as they didn’t find it easy to dispense the product from the bottle. Claiming it was more like a gel-like substance than a liquid. They recommended giving the bottle a hot bath by placing it in a 5-gallon bucket filled with hot water. The gel substance will then flow like liquid. Overall, a good-performing liquid nitrogen fertilizer.


  • Quick results
  • Works on shrubs and trees not just grass
  • Pet and children friendly 


  • The connector on the bottle is a little short
  • Expensive 

We couldn’t finish our review without recommending another natural liquid fertilizer from a family-owned, UK-based company, Envii. The 7-15-19 formula promises to improve the health of both soil and grass, with results within 7-10 days.

What makes this product so unique is its bio-stimulant technology that allows stronger root growth and increased resistance to heavy rain and drought. Furthermore, it is completely safe for children and pets as well as on other plants.

And if that weren’t enough, those who are concerned about the environment will be pleased to know that the container is made from recycled plant-based materials, so you can compost it after use!

Perhaps the biggest downfall of this product is its price. The 1-liter bottle only covers 300 square meters. There is also the bottle’s short connector that makes it almost impossible to connect to a garden hose. Go to this product on Amazon.

Customer reviews: the product has a score of 4.3 out of 5 as users were impressed with how quickly this liquid feed transformed their lawn. They even noticed the dead patches turning into a lush, dark green color soon after application. The one complaint they had was the short integral connector on the bottle, which doesn’t fit on a standard garden hose attachment. Best to use a pump sprayer instead. 


  • Ideal for all grass types
  • Turns grass green in the quickest time


  • Spray bottle may not work 

Another great product from the family-owned company Simple Lawn Solutions is the 3-18-18 formula. It is especially ideal for lawns that lack potassium and phosphorus. Made from organic ingredients, this high potassium and phosphorus liquid fertilizer encourages healthy and strong grassroots in the safest way. Thus, you won’t need to worry about damaging or burning your grass with harsh chemicals, as the product is completely natural.

Another excellent feature of this liquid fertilizer is its simple application. Just like all the other fertilizer products made by Simple Lawn Solutions, minimal effort and time are needed to apply this fertilizer.

Customer reviews: users rated this product 4.3 out of 5 stars because of how quickly it turned their grass green and healthy. Overall, this is another one of our favorite liquid fertilizers from the same brand that doesn’t burn grass or other plants thanks to its natural ingredients.


  • Super-fast-acting lawn fertilizer
  • Convenient spray attachment
  • High Nitrogen fertilizer 27-0-0


  • Last 4-6 weeks, so buy a multi-pack

Miracle-Gro EverGreen Fast Green Lawn Spray is a really fast-acting lawn fertilizer that claims to work within 24 hours. I’ve used it a few times, not sure I’ve seen it work in 24 hours, but it’s fast. Give it a few days and you can see the difference. With a very high nitrogen-based N-P-K 27-0-0, you get lush green grass that will last a month or so. I would suggest applying it every 4-6 weeks for the best results.

I like to consider this product as an emergency backup. Maybe, if your lawn is looking tired and you’re going to host a party or BBQ and you need that ‘get out of jail free’ card, then this is it. You apply it directly from the bottle with a hose attachment, making for a quick, easy solution.

You can buy this product online here, or at any good garden store.

Customer Reviews: Miracle-Gro customers usually want a simple-to-use and convenient fertilizer. Well, this brand of choice will not let you down, if that’s what you’re looking for. A plug-and-play spray bottle that delivers results within a weekend.


  • More area coverage
  • No assembly required


  • Not ideal for sprayers
  • May burn plants

As well as thickening your lawn, this product will keep out those pesky weeds. Warning: do not apply this fertilizer to newly seeded gardens as germination can get adversely affected. 

How to apply: mix 3 parts water to 1 part fertilizer and spray evenly on your lawn starting from the top. Every liter of corn gluten meal covers 1,000 square feet when mixed with water.

  • Ready and easy-to-use bottle
  • Ideal for newly sown grass
  • No mixing required


  • Not a lot of coverage
  • May take up to a season to see results 

Scott’s liquid turf builder comes with a ready-to-spray hose-end attachment to make the application super easy. This means there is no mixing required so you can use the product as soon as you receive it. On top of that, it’s safe for use on all types of grass.

Since you can connect the bottle to a garden hose, you can water your lawn at the same time. But, keep in mind that results take time, and several applications throughout the year are required.

This liquid fertilizer is ideal for thickening newly planted grass, making it an excellent choice for new lawns, whether planted from sod or seed. Scotts liquid turf builder works by going directly to the roots and stimulating new growth. Even healthy lawns that require a boost of nutrients throughout the growing season can benefit from this product.

When we tested the product, we found that it gave 35% faster results than granular fertilizers. However, the bottle only covers 600 square feet, which is a little disappointing. This is a product we are happy to recommend, you can check Scott’s Turf Builder Spray latest price online here

Customer reviews: users rated Scotts liquid turf builder 4.2 out of 5 for the great results it yielded. Their lawns became thicker and greener, but it didn’t happen as quickly as they had hoped. 


  • A great combination of minerals to tackle deficiencies
  • Low-cost liquid iron lawn fertilizer


  • Needs to be used in conjunction with nitrogen lawn fertilizer

Ferti-Lome Liquid Iron Lawn Fertilizer contains 0.5%chelated Copper, 3.25 % chelated Iron, 0.15 % chelated Manganese, 0.16% chelated Zinc.

The perfect way to deal with iron deficiency in lawns, citrus trees, houseplants, shrubs, trees, vegetables, and flowers. This is not a complete fertilizer and should be used in conjunction with a nitrogen fertilizer. Ferti-Lome Chelated Liquid Iron should be used to correct your lawn’s nutritional deficiencies when you have signs of yellowing or browning.

I recommend using this spray throughout the growing season around every 8 weeks for the best results. Buy Ferti-Lome Liquid Iron on Amazon.


  • Instant results
  • Great coverage 
  • No assembly required


  • Bottle is a little difficult to operate 

The 12-4-8 liquid lawn fertilizer formula from Medina is a ready-to-spray product that promises to turn your lawn green quickly.

What we especially like about this fertilizer is the reusable hose-end, liquid fertilizer sprayer bottle that provides up to 4,000 square feet of coverage. When used every month from spring to fall, this liquid fertilizer will turn your lawn thicker and greener. Pick up a bottle of Medina at

Customer reviews: users were pleased with how green and lush their lawns turned after the first application. They recommended applying the fertilizer first thing in the morning when the grass is moist to maximize the application. However, the product was only rated 3.8 out of 5 because of the bottle was a little tricky to operate and not creating a watertight seal with the garden hose. 


  • Ideal for all types of plants, trees, lawns, vegetables, and shrubs
  • This iron lawn fertilizer delivers quick results
  • An easy-to-apply liquid iron for lawns


  • Can stain hands and concrete

Okay, this may not be a product with outstanding marketing behind it, but for those anemic-looking shrubs and lawns, consider this liquid iron fertilizer for lawns from the brand Southern. It really is excellent. The product turns grass into a deep, rich green color, and can also be used on shrubs, vegetables, and flowers.

How to apply: mix liquid iron for lawns with water and apply it as a drenching spray on the lawn.

Customer reviews: with an impressive score of 4.5 out of 5 stars, users noted the huge difference in their iron-deficient shrubs and lawns within a week after application. The yellowing leaves of their trees and limp grass turned green and healthy, which makes this product one of our favorites in terms of value for money and performance. Important: customers recommended using gloves before applying liquid iron for lawn concentrate as it may stain your hands.   

How to Apply Liquid Nitrogen To Your Lawn

There are two ways to apply liquid fertilizer to your lawn, foliar or ground application. Since most liquid fertilizers are highly concentrated, before applying the product, you’ll need to make sure it is properly diluted. Otherwise, you risk burning your plants. Having said that, some of the products we reviewed were ready to use so all that’s required is to shake the bottle well to mix all the contents before connecting it to a garden hose.

Start from the top end of your lawn and spray in a side-to-side motion to cover the entire area.

In case the product you’ve chosen doesn’t come with a spray nozzle, you can use a hose-end sprayer or even a pump sprayer. The hose-end sprayer works similarly to a garden hose sprayer. 

A pump sprayer, however,  is a tank that you wear on your back after filling it with properly diluted fertilizer.  To operate this sprayer, you’ll need to add pressure to the tank using the handle. To release the fertilizer, hold the wand and press the button. Again, make sure you start from the top end of your lawn and spray your way down, so as to avoid walking over the newly fertilized grass. 

When to Apply Liquids 

When you should apply the liquid fertilizer on your lawn depends on which product you’re using. Make sure you read the instructions on the bottle as each product is either designed for spring and summer or year-round application. That said, liquid fertilizers are generally applied in spring to help your lawn absorb all the nutrients. 

Some of the products we recommended are specifically for spring and summer. The first application is given in spring with subsequent small doses applied every few weeks until early summer. 

Note, if you’re applying chemical liquid nitrogen fertilizer at the peak of the summer season, it may burn your lawn. It would be safer to use an organic liquid fertilizer early in the morning during the summer months, to avoid damaging the grass. On a final note, make sure the ground is moist when fertilizing your lawn for optimal effect. 

Best Time of Say and Season to Apply?

Apply liquid fertilizer during the cooler parts of the day, ideally early morning or late afternoon, to prevent evaporation and ensure maximum absorption. The ideal season depends on grass type: cool-season grasses benefit from spring and fall applications, while warm-season grasses prefer late spring to early summer.

How Often To Apply Liquid Fertilizer?

Application frequency depends on grass type, climate, and chosen product. Generally, applying every 4-6 weeks during the growing season suffices. Follow the manufacturer’s instructions and avoid over-fertilization, which can lead to nutrient imbalances, excessive growth, and environmental pollution.

How Much to Apply

How much liquid nitrogen fertilizer you should apply depends on your lawn’s size and how much nutrient it needs throughout the year. If you apply too little, you won’t get the desired results; apply too much and you may damage your grass, so it pays to know the right amount of fertilizer to apply.

Soil Testing

The best way to determine how much liquid fertilizer you need to apply is to test your soil. By using a soil test kit, you will know how much nitrogen, phosphorus, and potassium your lawn needs. There are many simple-to-use home test kits that measure all three of the main nutrients in your soil. The ones we like are in the form of capsules from Luster Leaf.  

Once you find out your soil’s deficiencies, you can then choose the right fertilizer. Check the product’s NPK ratio and be sure to follow the instructions.

Identifying and Addressing Common Issues?

Common issues include fertilizer burn, nutrient imbalances, and uneven growth. To avoid these, apply liquid fertilizer evenly and according to recommended rates. Water appropriately to promote absorption and prevent runoff. Monitor lawn health and consult a professional if issues persist or worsen.

Safety Precautions When Handling Liquid Fertilizers?

Wear protective clothing, gloves, and eyewear when handling liquid fertilizers. Avoid skin or eye contact and ingestion. Keep pets and children away during the application. Always follow the manufacturer’s instructions for proper use, storage, and disposal. In case of exposure or accidental ingestion, seek immediate medical attention.

Mixing Liquid Fertilizer With Other Products?

Some liquid fertilizers can be mixed with weed killers or insecticides for efficient, single-application lawn care. Check product compatibility, as certain combinations may be harmful or reduce efficacy. Conduct a jar test to ensure products mix well and apply as per the manufacturer’s instructions.

Proper Storage of Liquid Fertilizer?

Store liquid fertilizers in a cool, dry, well-ventilated area, away from direct sunlight, heat sources, and open flames. Keep containers tightly sealed and upright to prevent spills. Follow the manufacturer’s guidelines for shelf life and disposal of expired products.

Environmentally Friendly or Organic Options?

Organic liquid fertilizers, derived from natural sources like fish emulsion, seaweed extracts, and compost teas, offer eco-friendly alternatives. These products supply essential nutrients while promoting soil health and microbiome activity, reducing the need for synthetic inputs.

Verdict: Best Liquid Lawn Fertilizer

Liquid lawn fertilizers provide a simple, quick, and many times easy application for small and large yards. While these fast-acting products yield excellent results, they often require regular application for optimal lawn establishment. 

Whether you’re looking for a specific feed for your newly sown grass, or you want to give your tired, old lawn a new lease on life with a liquid iron for lawns, you’re bound to find the most suitable liquid fertilizer from our shortlist of outstanding products.

If you’re really still confused and just want a recommendation I would suggest Scotts Liquid Turf Builder for new lawns, and all the products from Simple Lawn Solutions are well worth checking out for established grass.
