How to Pick a Good Liquid Fertilizer – A Buyer’s Guide 

Your fertilizer will ensure the overall health of your lawn. Investing in a good fertilizer will provide you a greener and thicker lawn in a short amount of time. However, accidentally purchasing a bad fertilizer will create damaging effects on your lawn. 

Thus, we cannot stress enough the importance of finding the fertilizer specifically designed for your soil and grass. However, we know how difficult finding the correct fertilizer is, especially given the information overload. Thus, we will provide you some factors to consider when buying your liquid fertilizer. Limiting your choices will also remove many fertilizers that simply won’t match your lawn. 

Understanding Ratios

When deciding on your fertilizer, you must understand the N-P-K ratios. These three letters symbolize three of the most important nutrients your fertilizer must possess. These nutrients are namely: Nitrogen, Phosphorus, and Potassium. Each nutrient contributes to a characteristic of your lawn to create a beautiful output in the end. 

Not all soils are created the same. If you are lucky, you will be growing your lawn in a more neutral atmosphere. This means that you can purchase a fertilizer with a balanced ratio. This means that your lawn only needs an equal amount of each nutrient to grow healthily. 

However, some soils lack a particular nutrient. That means your seeds are being grown at a deficient state. This will most likely lead to your lawn not producing as many yields as your other lawn owners. Therefore, some fertilizers have an increased portion of a nutrient. If you are a lawn owner in this predicament, consider purchasing a fertilizer that provides the nutrients your soil lacks. 

Get an All-Natural Product

Natural products are significantly more expensive than synthetic products. However, natural-based fertilizers will ensure that your yard remains healthy and safe. Synthetic products could contaminate your lawn and damage it in the long run. 

Thus, investing in an amazing natural liquid fertilizer will ensure that your lawn is fed with the best products in the market. You will not have to worry about unwanted chemicals that might linger around. 

Moreover, you are also assured that more effort has been created to brew the fertilizer naturally. Some companies successfully created an organic liquid fertilizer that will provide fast and efficient results without jeopardizing the making process. Further, we know that more effort was put into the product to grow, mature, test, and distribute. 

Consider Professional Help

We also recommend requesting a professional to personally provide you a recommendation for the kind of liquid fertilizer you will need. Professionals will provide you a more accurate interpretation of your needs. 

Hiring a professional will save you less time speculating and trying different products at the risk of your lawn’s health. A professional will provide you the necessary information to avoid the costs of mistake. However, you will need to provide monetary compensation to compensate for his consultation. 

Nevertheless, if you are extremely dedicated to the health of your lawn, you will see this professional fee as an investment. This action will save you more time and money than speculating yourself. 


There you have it! We provided you seven of the best liquid lawn fertilizers in the market. We also provided you their pros and cons to aid in your buying decision. We provided you the best product and brand we believe will best serve your interest, either as an experienced or a beginning lawn owner. 

We also provided you the necessary information that you can use to consider when purchasing your new product. If you are still new to this environment, seeking professional consultation will save you more money than you would most likely spend trying out different things. 

All these choices will depend on you in the end. You will determine what is best for you and your lawn, and no one will be able to tell you otherwise. Thus, choose your fertilizer wisely because this will directly affect how beautiful your lawn will be in the end. Good luck, and enjoy the process!
