Can I Put Too Much Fertilizer On My Lawn

How Often Should I Fertilize The Lawn – Quick Tips

There is the idea of too much of a good thing, and that definitely applies when it comes to fertilizing your lawn! Applying too much fertilizer to your lawn will cause the nitrogen and salt levels in the soil to increase rapidly, which can damage or even kill the grass. When this happens, it is known as fertilizer burn and looks like yellow and brown strips or patches of dead grass. These symptoms can appear as soon as the day after a fertilizer application, making it easy to determine the cause.

How To Apply Lawn Fertilizer

There are several ways to apply lawn fertilizer. Using a spreader provides more even coverage than fertilizing by hand. Hand fertilizing often results in burns where the fertilizer is concentrated and pale areas that dont get as much fertilizer as they should.

Broadcast or rotary spreaders are easy to use and dont cause striping like drop spreaders. The advantage to drop spreaders is that there is no chance of overthrow getting fertilizer on streets, sidewalks, or driveways. With a drop spreader, you have to make two trips over the lawn at right angles. For example, if you make your first trip over the lawn in a north-south direction, the second trip should run east to west.

After applying the fertilizer, water the lawn thoroughly. Watering rinses the fertilizer off the grass blades so that they wont burn, and it allows the fertilizer to sink down into the soil so it can get to work. Keep kids and pets off the lawn for the amount of time recommended on the label, which is usually 24 to 48 hours.

How Often Should I Fertilize A New Lawn

Dont fertilize a new lawn until the grass is actively growing and you have mowed the lawn at least three times. Then use a fertilizer that will promote strong roots without a surge in grass growth while keeping the lawn weeds at bay.

For U.S. based gardeners, fertilize your lawn with Scotts Turf Builder Starter Food for New Grass Plus Weed Preventer .

U.K. gardeners should use a lawn fertilizer such as Miracle-Gro EverGreen Premium Plus Weed Control Lawn .

These fertilizers will slowly release nutrients into the lawn. You will only need to apply these once every 12 weeks while the lawn becomes established.

Its also worth mentioning that if you apply a crabgrass preemergent fertilizer or a regular weed and feed, ensure that you have waited four weeks before sowing your new grass seed.

Understanding Whats In Your Lawn Fertilizer

How Often Should I Fertilize My Lawn? (The Surprising ...

When choosing a fertilizer, youll need a basic understanding of the fertilizers NPK rating.

NPK rating is the fertilizers levels of:

  • Nitrogen,
  • Phosphorous, and
  • Potassium .

For a standard lawn, a good choice for your first application of the season is around a 20-5-10 NPK rating.

That means the fertilizer is comprised of 20% nitrogen, 5% phosphorous, and 10% potassium. Those three are the primary nutrients for grass, similar to how people need a proper balance of macro nutrients to thrive.

  • Nitrogen makes your lawn grow and green quickly, and its essential throughout the season.
  • Phosphorous promotes healthy root development. Thats why its recommended to apply high phosphorous fertilizers early in the season to help your grass develop strong roots early. If you water regularly and well, your lawns roots will be able to withstand drought and dryness in the hottest part of summer. However, Phosphorous in high concentrations is bad for the environment, so more places are regulating the allowed amounts or banning it altogether.
  • Potassium promotes overall grass growth for a healthy, balanced lawn.

Synthetic fertilizers are more potent and have higher NPK ratings, while organic fertilizers have lower ratings.

The higher potency of synthetic fertilizers is why they have more immediate results in making your grass green. However, thats also why they are unsustainable.

After you apply fertilizers, keep these tips in mind.

  • Dont use the lawn for at least 24 hours.;Keep pets and children away from the grass until its completely dry and the soil has absorbed the fertilizers.

Why Too Much Fertilizer Is A Bad Thing

When more fertilizer is added than a lawn needs, the salts in the mixture will accumulate in the soil and potentially kill the grass. Living in an environment with too much salt makes it difficult for plants to absorb much-needed water from the soil.

How to Spot Fertilizer Burn

If youve ever seen an unhealthy lawn with patches or stripes of brown grass, you likely already know what fertilizer burn looks like. Fertilizer burn can be more of a concern when:

  • You havent added enough water after fertilizing.
  • You use a quick-release fertilizer.
  • You apply fertilizer in extremely hot weather.

To avoid these issues, make sure to apply fertilizer during a cooler part of the day and water your lawn right after applying fertilizer.

Not only will the latter protect against fertilizer burn, but youll also be helping it be absorbed in the soil, which is right where you want it to be anyways.

You can also purchase fertilizer with slow-release nitrogen, which will avoid overwhelming your grass with salts before theyre needed.

How To Fertilize The Lawn

Discover how easy it is to feed your turf with fertilizer. For best results, start with an easy and inexpensive soil test, which tells you how much fertilizer to apply and what formulation to use.

Follow the directions on the fertilizer bag; most fertilizers are formulated to supply about 1/2 to one pound of nitrogen per feeding.

Hose
  • Step 1Step 1Determining Fertilizer Type

    Lawn fertilizers are distinguished by the N-P-K numbers on the front of the bag. These letters stand for Nitrogen , Phosphorus and Potassium and represent the percentage by weight of each of those nutrients in the fertilizer. Nitrogen helps plants grow and green up, Phosphorus stimulates deep root development and Potassium provides all around health and disease/drought resistance. Choosing the right combination depends on a number of variables including sunlight exposure and climate.

  • Step 2Step 2Measure Out Fertilizer

    Follow the directions on the bag carefully. Determine the size of your yard then measure out the right amount of fertilizer. Depending on the measurement, using the whole bag may mean you’re applying too much or too little. Never apply more fertilizer than the soil test or fertilizer label instructs. Even distribution is key. A great way to do this is to use a quality spreader, which ensures that the nutrient particles are evenly over the lawn, which will keep the health and colour consistent throughout.

  • How Often Should You Put Epsom Salt On Your Lawn

    Some homeowners like to use Epsom salt as a natural lawn fertilizer in the spring to facilitate lush green growth. Epsom salt contains magnesium, which is key to seed germination, chlorophyll production, and improving the uptake of nitrogen, phosphorus, and sulfur.

    To try this method, add 2 tablespoons to each gallon of water used on the lawn. If you have a sprinkler system, lightly sprinkle the salt directly atop the grass and then allow the system to water it into the sod.

    Mixing Urea With Other Fertilizers

  • 1Determine your ideal fertilizer ratio. Fertilizer ratios, also called N-P-K numbers, are a series of 3 numbers that tell you how much of a fertilizer mixture, by weight, is made up of fertilizers rich in nitrogen, phosphorus, and potassium. If you have a sample of your soil studied, you will be provided with an ideal fertilizer ratio that will help make up for your soil’s nutrient deficiencies.XResearch source
  • Most hobbyist gardeners can find premixed fertilizers that will suit their needs at a plant nursery or garden supply center.XResearch source
  • 2Combine urea with additional fertilizers to create a stable fertilizer mixture. Urea provides plants with nitrogen, but other elements, like phosphorus and potassium, are important for plant health as well. Fertilizers that you can safely mix and store with urea include:
  • Calcium cyanamide
  • Sulphate of potash
  • Sulphate of potash magnesium
  • 3Mix urea with certain fertilizers to fertilize plants immediately. There are certain fertilizers that can be mixed with urea, but lose their effectiveness after 2-3 days because of the reactions that occur between the fertilizer’s chemicals. These include:
  • Chilean nitrate
  • Rock phosphate
  • Muriate of potash
  • 4Prevent unwanted chemical reactions from harming your crops. Some fertilizers will react with urea to either create a volatile chemical reaction, or to render the fertilizer mixture completely useless. Never combine urea with the following fertilizers:
  • Calcium nitrate
  • Be Wary Of Fertilizer Application Rates

    How Often Should I Fertilize My Lawn?

    Across the board, most fertilizer manufacturers are overzealous about their recommended dose and feeding schedule. Start light with half the recommended amount and rate of fertilizer. You can reapply if you don’t like the results. Over a season or two, you’ll get a clear sense of how much it takes to get a healthy lawn.

    A healthy lawn will be a relatively light shade of bright green. A lawn that is a deep, almost blackish green, has been very heavily fertilized. The dark green color comes from a lot of nitrogen-based fertilizer used on the lawn. It is highly likely that some of that fertilizer has run off into the streets, storm sewers, and has made its way into local streams and rivers.

    Best Time To Fertilize Lawn

    Fertilizing in the morning allows the soil to take in the most nutrients, soak in the morning dew and take advantage of cooler temperatures. Thats the best time. Do not apply fertilizer on an abnormally hot day, not even in the morning. Wait until the weather cools back down to a normal temperature.

    You can mow anytime after fertilizing with a granular treatment. With a liquid treatment, wait a day or two.

    After Your First Lawn Fertilizer Application

    So now you know about the first treatment, but are wondering how often to fertilize lawn areas throughout the rest of the year?

    After your first application, you want to apply another round of fertilizer 6 to 8 weeks later and repeat that two more times with 6 to 8 weeks in between.

    Try to schedule your applications so you apply ahead of the hottest part of summer to give your lawn the necessary boost.

    For an established lawn, youll fertilize 4 times each season, though that is based on some important assumptions. If your grass is damaged and youre growing it fresh, your lawn will require more treatments until its established.

    This is also true if your lawn has a species of grass that isnt native to your climate, like in areas that are more hostile to grasses. Alternatively, the opposite is also true. Fertilizing regularly is most necessary when trying to keep alive grasses that arent native to your area.

    Its very likely you can get away with only fertilizing 1 to 2 times per year if the grass in your lawn is native. A healthy lawn can get by with fertilizing in the spring, and maybe again In the fall to keep it strong through the off-season.

    Applying Urea On Its Own

  • 1Minimize ammonia loss by applying urea on a cool day. Urea is best applied on a cool day, in weather between 32° to 60° F , and with little to no wind. At colder temperatures, the ground is frozen, making it difficult to incorporate the urea into the soil. At higher temperatures, and in windy conditions, the urea is broken down faster than it can soak into the soil.XResearch source
  • 2Use a urea fertilizer with a urease inhibitor before planting. Urease is the enzyme that begins the chemical reaction that turns urea into the nitrates plants need. Applying urea fertilizers before planting leads to high amounts of the urea being lost before it can benefit your plants. Using a fertilizer with a urease inhibitor can slow the chemical reaction, and helps retain urea in the soil.XResearch source
  • 3Spread the urea evenly across the soil. Urea is packaged and sold as small, solid pellets or granules. Broadcast the urea with a fertilizer spreader or sprinkle the pellets by hand evenly across your soil. For most plants, you will want to keep the urea close to the plant’s roots, or close to where you will plant the seeds.XResearch source
  • 4Wet the soil. Before urea is turned into the nitrates your plants need, it first becomes ammonia gas. Because gases can easily escape from the surface of the soil, applying fertilizer when the ground is wet will help to incorporate the urea into the soil before the chemical reaction begins. This way, more of the ammonia is trapped within the soil.
  • Fertilization For Spring And Fall

    How and when do I fertilize my lawn?

    In spring, as the temperature rises and the grass begins to grow, apply a slow-release fertilizer to help the lawn ease into the growing season. In late fall, give the lawn one last feeding, using a slow-release fertilizer. This last feeding helps the lawn get a better start next spring when new growth begins. While a 15-5-10 is a good concentration for lawns, a concentration of 10-15-10 with more phosphorous can be used or lawns with a weed problem.

    Apply Grass Fertilizer Correctly

    Now you’re ready to apply. Feeding the lawn is as simple as mowing it, and as easy as walking at your normal steady pace. Just follow these guidelines for easy application and even coverage.

    If youre using a broadcast spreader, feed the entire perimeter of your lawn first. Engage the side-shield, which blocks off one side of the spreader to keep the product on the lawn and out of gardening beds and off driveways and sidewalks. Next, fill in the middle by turning off the side-shield feature and walking back and forth in straight lines. To get even coverage, overlap slightly on each pass by moving over 2 steps before you begin the pass.

    When using a drop spreader, start by applying 2 header strips at opposite ends of the lawn to create a turning area. Next, fill in the rest of the lawn by applying the fertilizer back and forth in straight lines perpendicular to your header strips. To ensure you get even coverage, be sure to overlap the wheel tracks by about half a foot .

    After youve finished feeding your lawn, return any unused product to the bag and store it for future use.
