Regardless of your geographical location, if you have a lawn it is likely turfgrass. Turfgrass is made up of any variety of grass to form a turf, the healthiest of which are thick, green, and free from weeds and bare spots. Turfgrass is like any plant, in that to reach its truest, greenest potential, you need to feed it. Using fertilizer is one way to feed grass, but there are many ways you can feed the grass and the microbes in your soil to achieve a fuller, greener lawn.
Fertilizer is the most common way to feed grass. Fertilizer is a chemical or natural substance that is added to soil to increase its fertility. Essentially, the soil is the growing medium for your grass, and the more nutrients the soil has, the better your grass will grow. Fertilizers add beneficial nutrients to your soil like a multivitamin adds nutrients to your diet. Some fertilizers also help the soil to retain water and allow air to flow, helping the roots of your grass.
The first three elements, oxygen, hydrogen, and carbon, are all consumed by the plant above ground through the air and rain. Nitrogen, phosphorus, and potassium get absorbed through the soil. Even the most fertile soil will eventually be depleted of these vital nutrients as the plants eat and grow, which is why using fertilizer is essential to growing greener, healthier grass.
All fertilizer’s labels include the percentage of these nutrients, or elements, with three numbers separated by dashes representing N, P, and K. The higher the number, the more of that particular nutrient. The rest of the fertilizer’s formula is fillers that work to distribute the nutrients evenly so the blades of the grass don’t get burned.
The breakdown of the fertilizer you use depends on your goal for your lawn. If you’re looking to feed grass to encourage better overall growth, use a balanced blend. Use a fertilizer higher in nitrogen for more lush, green growth. For winterizing your yard, or protecting from disease, feed grass with a fertilizer that is higher in phosphorus and potassium.
Always read the label on your fertilizer before you feed grass, do not over-fertilize, and do not fertilize new grass for at least a couple weeks as it can stunt growth. Always feed grass in early spring, and in the fall, and as often as your particular species of grass will tolerate.
There are many different types of fertilizers you can use, and it’s perfectly acceptable to try different kinds and see which works best for you and your lawn.
Lawn care experts recommend liquid fertilizer for many reasons. Liquid fertilizers have a more homogenous mixture, meaning that every drop feeds grass with the same nutrient contents. Liquid fertilizer also has lower salt content, which means you’re less likely to cause burns when you feed grass. It’s also easier to apply and lasts about four weeks, meaning you can use the same product to feed grass throughout the growing season.
Using liquid fertilizer to feed grass on a schedule every couple of weeks keeps the lawn consistently growing, maintaining a pristine and neat aesthetic. Unlike using a granular fertilizer to feed grass, you don’t have to water immediately following application with liquid fertilizer. Grass absorbs liquid fertilizer through the leaves, so for best results, apply liquid fertilizer the day before it’s supposed to rain. By applying this way, nutrients get absorbed through the leaves, then the following day, the rain works the remaining nutrients into the soil.
Liquid fertilizers are the easiest way to feed grass but always dress appropriately. Wear long pants, long sleeves, and boots to protect your skin. Simple Lawn Solution products can be attached directly to your hose to spray onto your yard without mixing the product manually. You can also use a backpack sprayer to be sure the liquid fertilizer doesn’t get too diluted.
Start with the perimeter of your yard and work inward, or walk in parallel lines to make sure you spray the whole lawn evenly. Kids and pets can get back on the lawn as soon as the liquid fertilizer dries. Using liquid fertilizer to feed grass is as easy as that!
Feed grass with liquid fertilizer at least twice annually, at the beginning and the end of the growing season. As you anticipate the weather getting warmer, and your soil starting to thaw, plan to aerate and dethatch your lawn. After you’ve loosened your soil, feed grass for the first time.
As the hot weather draws to an end, feed grass with liquid fertilizer again, to protect it over the cold weather. These are good basic lawn care practices, but using liquid fertilizer twice a year is the bare minimum.
For optimal growth, you should feed grass with a liquid fertilizer every six weeks during the growing season. The growing season for grass is typically when the weather ranges from about 60-80 degrees Fahrenheit. More growth means that your grass will utilize more nutrients, so you might need to increase your use of liquid fertilizer to feed grass more or less, depending on how fast your grass is growing.
While it’s crucial to feed grass to keep your yard looking it’s best, be sure not to over-fertilize, as you’ll be doing more harm than good.
Apply liquid fertilizer late in the afternoon to evening, avoiding the hottest part of the day. Adding liquid fertilizer to grass in the midday sun can scorch the grass, causing browning - the exact opposite of what you’re trying to achieve. Don’t apply the fertilizer to wet grass either, even if it’s just from dew. Wait until the grass dries before feeding.
Aside from the start and end of your grass’s growing season, there are some additional occasions you will want to feed your grass, as well. Be sure to apply fertilizer before you plant new grass. By doing this, you ensure that your soil has all the nutrients the new growth needs readily available.
If you’ve gotten too liquid fertilizer-happy, your lawn might experience the following:
If you’ve over-fertilized, remove the visible layer of fertilizer and do not add more soil. After you’ve taken this first step, you next need to flush out as much of the liquid fertilizer as possible. Do this by watering your lawn until it cannot absorb any more water. Then, continue watering your lawn every morning until you’re sure the excess liquid fertilizer is flushed.
Once you’ve over-fertilized, don’t feed grass again until you’ve nursed your lawn back to health.
Most lawn and gardening experts rave about compost. There is a distinction between compost and fertilizer, and for best results, many people use fertilizer in conjunction with compost. The reason for combining the two is that while fertilizer feeds the grass, compost feeds the soil.
Compost is decomposing organic matter, full of millions of microbes that help to cycle through nutrients in the soil, making them available to feed grass. You can buy compost, or make your own with kitchen scraps and grass clippings.
Making your own compost is easy, cost-effective, and good for the planet. Purchase a composting bin, or if you have enough land, start your compost on bare ground.
The secret to healthy compost is to have a higher ratio of carbon-emitting material than nitrogen emitting material.
Another popular tip with lawn experts is to let your grass clippings (from mowing your lawn) lie. Grass clippings decompose and become an additional method to feed grass. While not enough to replace liquid fertilizer, grass clippings can give your yard a boost of food between your regularly scheduled fertilizer applications.
A common misconception about leaving grass clippings to lie is that it leads to thatch build-up, but this is not the case, as long as you are correctly mowing your grass. By this, we mean as long as you’re not removing much more than ⅓ of the length of your grass, the clippings break down and are reabsorbed fairly quickly. If you let your grass get long and then hack it all off, that is not the time to let the clippings lie, as they will accumulate faster than they can break down, which does contribute to a build-up of thatch.
As mentioned before, grass clippings can be a part of your homemade compost material, if you decide to bag them up as you mow.
There are many ways to feed grass and maintain a beautiful green lawn effectively. Seasoned experts find ways to incorporate more than one way for the best results. Take your time to figure out what works for you and your grass, but a great place to start is a quality liquid fertilizer and allowing your grass clippings to lie.
