Does My Lawn Need Dethatching Or Power Raking

Dethatching vs. Scarifying: When should I scarify my lawn? // Lawn Rehab / Overseeding – Part 3

The Minnesota lawn care experts at our lawn mowing and maintenance company know that dethatching lawns is an important chore that most homeowners overlook. Every lawn has a layer of thatch at its base, made up of both living and dead grass stems and roots. As this layer becomes thicker and more compacted over time, necessary nutrients, water, and air can be blocked.

The result is grass that looks green on the top, but is brown and dead looking near the bottom of the blades. Grass with too much thatch often looks brown and has a scalped appearance after being mowed. It can also feel spongy when you walk on it. Since water isnt properly absorbed, a lawn with too much thatch is hard to keep watered and will dry out easily. Without proper treatment, the problem will keep getting worse.

In Minnesota, the ideal time for power raking is in the fall, just before grass goes dormant. However, this service should not be done while the soil is wet and spongy, to avoid pulling up grass by the roots. We can advise on the right time to have this service done.

We offer affordable pricing for power raking. Our service area covers most of the Hennepin county, including Minneapolis, Plymouth, Minnetonka, Maple Grove, Wayzata, Golden Valley, St. Louis Park, Blaine, Coon Rapids, New Hope, Edina, Bloomington, Eden Prairie, Crystal, Richfield and Brooklyn Park.

Is Raking Bad For Your Lawn

Although people often rake and bag leaves to prevent their lawns from being smothered and to make yards look better, in most cases, youre fine not moving them. In fact, many environmental experts say raking leaves and removing them from your property is not only bad for your lawn but for the environment as a well.

Dethatching Vs Aeration What Is The Difference

Many new homeowners cant tell the difference between dethatching and aeration. Are the two the same? Absolutely not!

When you are dethatching your lawn, you remove the dead layer of grass roots found between the grass and soils top layer.

On the other hand, aeration involves punching holes in your lawn, creating passageways for air, water, and nutrients.

While you might remove some thatch when aerating, you dont remove much of it as when dethatching.

. Hereof, is dethatching a lawn necessary?

In the north, late summer or early fall before the grass goes dormant are good times to dethatch, and late spring in the south. For small areas, you can use a hand dethatching rake. Thatch builds up over time, so it’s not necessary to dethatch every year. Plan on doing it every five years or so if your lawn needs it.

Beside above, how do I know if my lawn has too much thatch? Walk on the lawn to see if it feels firm or spongy.The first thing that gives you a hint at whether or not your lawn needs to be dethatched is the feel of it. Walk around for awhile and see if the ground feels firm. If it feels spongy, or almost bouncy, that’s a sign that the thatch has gotten too thick.

Just so, when should you Dethatch a lawn?

The lawn should be dethatched when it is actively growing and the soil is moderately moist. The best time of year for dethatching is the same as for aerating: early spring or early fall for cool-season grasses, and late spring through early summer for warm-season grasses.

Is it better to dethatch or aerate?

Thatching is sometimes called dethatching. It removes a dead layer of roots and stems that is found between the grass base and the native soil. This is more stressful to your lawn than aerating is, and is generally only done if your lawn is thinning out due to thick thatch, according to Organic Lawn DIY.

Assessing Your Thatch Layer

To determine if your lawn has an excessive amount of thatch, look at, feel, and even measure the thatch layer. What you’re looking for is a thatch layer that’s thicker than 1/2- to 3/4-inch, which means it’s time to dethatch.

Get down on your belly and comb your fingers through the grass. You should be able to see some soil through the grass blades. You should also be able to poke your fingers through the thatch layer and into the soil fairly easily. If the soil is very hard to see or get through, you probably have an excessive thatch layer. Also check how the turf feels underfoot springy and spongy means too much thatch. Finally, you can take a “core sample” of your turf by opening a vertical slice of it with a shovel and measuring the thatch layer with a ruler.

Dethatching Machines Tools Techniques

Dethatching machines come in various forms. And although some lawn services and rental companies use the terms interchangeably, the machines perform dethatching by different means, with varying levels of intensity.

Here are some of the most common dethatching techniques, and the power dethatchers that perform them. What they have in common are spinning metal pieces that pierce and lift the thatch from the lawn. Some employ slicers, others metal tines . Some are stand-alone, powered units, others are made to be dragged behind a tractor or riding mower.

What Is The Best Aerator To Use On A Minnesota Lawn

Rent a core aerator from your local hardware store. These machines do the best job because they remove cork-shaped cores of soil from the ground and drop them on the lawn surface. This promotes true soil decompaction, breaks up thatch, and allows nutrient and water penetration.

Spike aerators wont do the job nearly as well. By driving a spike into the soil you are actually compacting all the soil around the spike. This a negative in the long run. If you want a healthy lawn, go with a core aerator.

When To Schedule Lawn Maintenance

It is important to schedule your lawn care maintenance during times that match the life cycle of the turfgrass.

  • Do not add fertilizer too early in the spring. This may encourage the grass to grow during a time when it should be slow or dormant.
  • Do not spray to control weeds when temperatures are warm. This increases the likelihood of damaging the lawn.
  • Do not fertilize in hot mid-summer months. This can cause irreversible damage to your lawn.
  • Crabgrass doesn’t develop until late spring or early summer, so don’t apply herbicide used to prevent pre-emerging crabgrass in the fall.

Why Aeration Is Important

When Should I Dethatch My Lawn In Minnesota ...

Aeration helps prevent soil compaction and increases water absorption and root development, which results in greener, healthier, stunning lawns.

If your yard receives heavy use as a playground for your kids or your dog running in circles, your soil will be compacted over time. Or if you have a new build, the construction traffic will have compacted the subsoil of your yard. Soil compaction results in poor nutrient uptake and water absorption.

Aeration also helps reduce excess thatch or soil layering. If your yard dries out easily and has a spongy feel, you may have a thatch problem. Soil layering happens when new finer soil, like when installing new sod, is layered on coarser soil. This finer layer traps water and which prevents deep root growth into the lower coarser layer. Aeration helps the water reach the lower layer.

What Is The Best Time To Aerate A Lawn

Late summer and fall is the optimum season. Why fall? Blame it on summer. Thats when many lawns become compacted from heightened activity, foot traffic and dry weather. Fall aeration alleviates the compaction, preparing the soil to grow healthy grass the following spring.

Spring aeration is an alternative, but if you aerate in the spring, you could unearth weed seeds and cause unnecessary weed growth. And if youre applying a crabgrass preventer in spring, punching holes in your lawn after treating with a pre-emergent herbicide can compromise the chemical barrier it creates to prevent crabgrass and other weeds.

The absolute worst time to aerate is during hot, dry weather, which could quickly dry out the grass, causing undue stress to your lawn.

When Is The Best Time To Dethatch Your Lawn

With most lawns in Minnesota being a cool season turf, it is recommended to dethatch your lawn in the early spring or early fall. Timing is everything, especially in the fall because you need to give your lawn ample amount of time to grow and re-establish its roots before frost begins to form on your lawn.

How To Dethatch Your Lawn

How to DETHATCH your lawn. 4 reasons WHY you want to do it and WHEN you should.
  • Tackle small lawns with a dethatching rake, and rent a dethatcher for larger lawns
  • Mow your lawn to half its normal height before you begin dethatching.
  • Use a dethatching rake like you would a regular rake. Dig the tines into the thatch and pull it upward, helping to loosen and remove the buildup. While you rake, you should feel and see the thatch separating from the soil.
  • If youre planning to rent a dethatcher, mark any shallow irrigation lines, sprinkler heads, or buried utility lines before starting. This is no time for surprises!
  • Ask the rental agency to adjust the spacing and cutting depth for your grass type. The blades should be set to cut no deeper than ½ inch into the soil. Make sure to get directions for how to use the dethatcher, and follow all of them carefully. A dethatcher is heavy, so ask for help loading and unloading it, and know that youll need a truck to move it.
  • After dethatching, your lawn will look ragged. Use a leaf rake to get rid of the thatch you loosened up.
  • If bare spots were created by dethatching, use a patching product, like Scotts® EZ Seed®, to repair them.
  • Now you can feed the rest of your grass. Once thats wrapped, water your entire lawn to help it recover from all of the poking and prodding.

    How Often To Dethatch

    How often you should dethatch depends on how fast the layer builds, and this depends on several factors. For example, lawns that are over-watered, growing in heavy clay soils, or are over-fertilized can accumulate thatch layers more rapidly than lawns receiving proper care and maintenance.

    The grass species also influences thatch buildup. For example, the Missouri Botanical Garden states that bermudagrass , hardy in U.S. Department of Agriculture plant hardiness zones 7 through 10, can build a thick thatch layer within several months and require annual dethatching. Perennial ryegrass species, such as English ryegrass , hardy in USDA zones 3 through 8, produce little thatch and only require dethatching every few years, says the Missouri Botanical Garden.

    Is It Better To Dethatch Or Aerate

    Dethatching and aerating seem to do the same thing, but theres time for each. So should you dethatch or aerate? Core aerating not only breaks up thatch buildup but also relieves compacted soil.

    Dethatching mostly loosens the top layer of soil and also removes the layer of debris from the soil. Dethatching can really help when overseeding your lawn.

    • Choosing vigorously growing grass varieties
    • Applying excessive amounts of nitrogen, especially in spring
    • Growing species that are known to produce large amounts of tough, fibrous tissue
    • Compacted soil conditions leading to shallow root development

    These factors decrease the rate at which thatch decomposes:

    • Acidic soil conditions
    • Poor soil aeration and waterlogged soils which limit microorganism activity
    • Pesticides such as insecticides or fungicides that restrict microorganism or earthworm activity
