A healthy, green lawn is a joy to sink bare feet into, and complements the landscape. The best fertilizer for grass will promote healthy turf and minimize weed and pest issues with a thick mat that resists these problems. There are many types of lawn fertilizer on the market, or you can use home-grown methods to enhance the vigor of your grass. Choosing the right food for lawns begins with understanding grass fertilizer numbers and knowing your soil and sod type.

Grass Fertilizer Numbers

Lawn maintenance is more than just mowing, thatching and aerating. Turf grass is a heavy feeder and requires regular moisture to look its best. All plants benefit from basic macro- and micro-nutrients. Grass, in particular, needs extra macro-nutrients which can come from air and water, but which are used in such quantity that supplemental applications are beneficial.

These main nutrients are nitrogen, phosphorus and potassium and are symbolized on grass foods as N-P-K. A soil test is a great way to decide which of these ratios is needed in the highest amount.

The ratio of nutrients on any plant food is represented by N-P-K and states the amount of each. For instance, a 10-10-10 is a balanced food with equal parts nitrogen, phosphorus and potassium.

  • Nitrogen promotes foliar growth and color.
  • Phosphorus is useful in encouraging flower and root growth, and early establishment.
  • Potassium in lawns enhances the plant’s ability to use nitrogen.

Soil tests are easy to use and will indicate which, if any, nutrient the area might be deficient in. This will tell you which nutrient ratio needs to be highest.

Other factors for choosing what type of lawn fertilizer to use are warm- or cool-season grass varieties, soil pH, whether you prefer organic or synthetic formulas and the timing to feed your grass in your zone.

Understanding the Types of Lawn Fertilizer

Using a fertilizer for lawns is an effective way to prevent disease and pest damage and minimize maintenance. But what type of lawn fertilizer to use?

  • There are time-release fertilizers which are beneficial for feeding the lawn over many months, and prevent the gardener from having to remember to feed again at a certain time.
  • The gradual release also allows plant roots to harvest the nutrients they need slowly, preventing necessary elements from leaching away into the soil. This type of food is easy to apply and minimizes the chance of burning the lawn.
  • Granular fertilizers may be time release or slow release. Either way, they are popular due to the ease of application.
  • Liquid or water soluble fertilizers are spread using a hose, and provide a quick effective way to introduce nutrients rapidly to grass roots.

Many of these forms come in either synthetic or organic forms.

  • Synthetic formulas are chemical and offer immediate release and quick greening of the lawn.
  • Organic formulas are naturally made from once living organisms or their byproducts.

The choice is yours on which application type and formula to use on your lawn.

No Muss No Fuss Fertilizer for Lawns

The lazy gardener can combine a need for organic, homemade treatment and provide much of the same benefits as purchased products. The easiest way to develop a healthy lawn without adding purchased items is to mow it.

Mow leaves onto the lawn and leave the clippings. If you mow frequently enough, the thatch will not build up because shorter clippings will compost in quicker and start amending the soil and adding nutrients.

The combination of grass clippings and dried leaves hastens the composting process because one is a carbon source and the other is a primarily nitrogen source. This is a one-two punch in the composting world, which breaks down more quickly than nitrogen alone from the clippings.

You may find this the best fertilizer for grass and save some pennies along the way.

If you have a problem with weeds in your yard, it’s important to find the best grass fertilizer with weed killer to keep your lawn looking neat and weed-free all summer.

While you can always buy fertilizer and weed killer separately, there are plenty of products that combine them, which makes these landscaping tasks much easier. Of course, everyone’s lawn is different — some have tons of weeds, some have only a few — but because these mixes also include fertilizer, they’re good for nearly every type of lawn.

The best grass fertilizer with weed killer is one that will last a long time (preferably all summer) and will prevent multiple types of weeds, like crabgrass and dandelions.

Most grass fertilizers with weed killer come in large bags or spray bottles. Keep in mind how much product you’ll get for the price, as one bag may be enough for a smaller yard, but you will need multiple bags if you have a lot of land.

How To Choose The Best Liquid Fertilizer For Your Lawn

As we have already mentioned before, there are various types of liquid fertilizers that you would come across, whether you are shopping online or going to a store.

Liquid fertilizers are usually a quick release feed used by the user for the many benefits that it provides. But there are various stipulations that you have to consider before you invest your money on a special fertilizer.

1. Are You In Need Of Instant Results?

As liquid fertilizers provide your lawn with quick-release nutrients, it can be used for treating various nutrient specific deficiencies within a short period.

If you want to make your yard look beautiful and healthy at the same time, then the best way to do it is by using a liquid fertilizer. They consist of essential nutrients like nitrogen, potassium, and potash that can bring life to your lawn within four days.

However, you have to keep in mind that using too much fertilizer is not good as it can further derogate the quality of the soil and the plants of your lawn. Every fertilizer comes with a usage guide that the users must follow to get the best results.

2. How Big Is Your Lawn?

If you have a moderate to a large lawn, then using a liquid fertilizer would be the best option for you. Liquid fertilizers can be spread across the park easily within a few minutes, without the user feeling exhausted. You can even attach the bottle of liquid fertilizer to a hose-end sprayer, and you would be able to fertilize large acres of land within a short span and without facing any hassle.

3. Do You Have A Weed Or Insect Problem?

The best thing about liquid fertilizers is that they can cater to various insect and weed problems, compared to their contemporaries.

You can buy fertilizers that feed to specific issues, or you can also buy a fertilizer that would take care of both the problems.

In addition to that, you would also be able to keep your lawn healthy at the same time. This is one of the best advantages of using liquid fertilizers, as it prevents the user from spraying harmful and chemical pesticides on their lawn.

Most fertilizers these days are organic and are made up of natural recycled products, which helps the plants, grass, and vegetables grow in the healthiest way possible.

4. Do You Own The Required Equipment?

If you have a large lawn, garden, or turf, then fertilizing it with a liquid fertilizer would become a costly affair. You should have a piece of sprayer equipment which would help you to spray the compost in a proper ratio around the lawn.

You should consider the cost of the material in the overall budget for your lawn maintenance, as it is one of the essential devices which you would be needing. In case you are on a budget, and you would not be able to spend much, then you should not opt for liquid fertilizers.

These are the few things that you should keep in mind before you plan to buy a liquid fertilizer. Once you have thought these through, then you can go ahead with our list of the best liquid fertilizer for the lawn.

Fertilizer Ratios: Which Is Best for Your Lawn?

If you’re a newbie to lawn fertilizer, then the numbers listed on the bag may seem like a foreign language. These three numbers are known as fertilizer ratios, and by understanding what each number means, you can improve the appearance and longevity of your lawn.

Each of the three numbers listed on the front of the bag of fertilizer represents nitrogen, phosphorous, and potassium. These are essential elements in growing a beautiful lawn. Together they are known as NPK ratios, and are indicated using their element symbols that you may remember from chemistry class. Each one serves a different purpose in ensuring your grass grows green.

  • Nitrogen (N): An essential element for plant growth, this element ensures your grass is plush and vibrantly green. Without enough nitrogen, grass will turn a yellow-green tinge and will hardly grow.
  • Phosphorous (P): This element stimulates the grass at its roots. By having adequate phosphorous levels you ensure that your grass grows fast and without discoloration.
  • Potassium (K): A major component in guaranteeing your lawn will withstand the elements potassium strengthens each blade of grass making it more resistant to potential diseases.

Which Ratio To Choose

NPK ratios apply to all types of fertilizer, but there are certain specifications to follow for lawns and all of the different conditions the lawn may be in.

  • New Lawn: For a new lawn, it’s important that both phosphorous and potassium be the larger percentage of the ratio. New lawns require more attenti on to the health of their roots, and of course strength in order to grow full and plush. Using ratios like these should be short lived as phosphorous ultimately leads to major environmental issues.
  • Existing Lawn: With an existing lawn, the roots are most likely strong and established. Because of this, the phosphorous and potassium levels don’t need to be quite as high as those needed for a new lawn. Nitrogen is cheaper in comparison to phosphorous and potassium as well, so fertilizer with this kind of ratio is not only best for your existing lawn, but your wallet as well.
  • Strained Lawn: As mentioned before, potassium provides strength to your lawn. In extreme weather, a fertilizer with a high potassium percentage will help it to push through harsh weather conditions. Use a fertilizer with high potassium levels before the peak of summer heat, and winter freeze for best results.
