When should you not dethatch your lawn?

Never dethatch when your lawn is dormant or stressed; you can damage it beyond recovery. Lawn aeration and dethatching are two different processes, but they can work together to help your lawn.

What month should I dethatch my lawn? For northern grass the best time to dethatch your entire lawn is in late summer to early fall when the grass is actively growing.

Can dethatching hurt your lawn? Spring dethatching hits a lawn hard when it is already in a precarious condition. Secondly, dethatching in the spring with power equipment can bring up crabgrass and other noxious weed seeds, setting your lawn up for a future infestation.

What depth should I dethatch? As a general rule, plan to dethatch your lawn when the thickness of the thatch is more than 1/2 inch deep. To determine the thickness, remove a small square of your lawn to a depth of about 3 inches and measure the brown layer between the grass blades and the soil surface.

Should you mow before or after dethatching? Mow your lawn to half its normal height before you begin dethatching. (FYI: Don’t fertilize before 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.

Should I fertilize my lawn after dethatching? After dethatching, rake up the newly exposed thatch. Mowing your lawn will also help to clean things up. Fertilizing at this time is also important. This will help your lawn recover and get much needed nutrients.

Should you overseed after dethatching? Both aerating and dethatching are recommended before overseeding because they improve grass-to-soil contact for proper germination.

To check, just work your fingers into the grass and note the depth of the thatch layer. Dethatch cool-season grasses in fall, warm-season types in early spring.

How do you smooth out a bumpy lawn?

Use a garden rake to break up raised areas and level them out to the surrounding yard. The best way to smooth out bumpy lawns is a combination of aerating and soil leveling.

Should I core or dethatch my lawn? The lawn should be dethatched when it is actively growing and the soil is moderately moist. We recommend dethatching in early spring or late autumn to allow the lawn to recover. Lawns with deep thatch exceeding three-quarters of an inch may be best to dethatch in two treatments.

What height do you set a Dethatcher? You want to remove thatch that is right above the soil without tearing it up. A height of about a quarter-inch (6.35 millimeters) above the soil may work — adjust the blades while they are on a smooth surface. They may need to be slightly higher for delicate grasses.

Do grass clippings create thatch? Contrary to a popular lawn myth, leaving clippings on the lawn does not cause thatch, which is a layer of partially decomposed grass-plant parts between the soil and live grass. Grass clippings are mostly water, so as long as you mow regularly at the right height, they will break down and disappear rapidly.

Do I need to aerate my lawn after dethatching?

Although a thin layer of thatch is beneficial, thatch accumulation should not exceed 1/2 inch. Excess thatch blocks out air, light and water from reaching root zones. Dethatching and aeration services go hand in hand. Dethatch first, then aerate.

Will dethatching remove crabgrass?

A: A dethatcher will tear out some of the dead crabgrass but won’t get it all. The crabgrass will break down and disintegrate over winter anyway. The real problem is the seed these plants let behind to germinate next year.

How do you pick up grass after dethatching?

Pull-behind Lawn Sweeper If you are dethatching big areas, your best option for clean up is probably the pull behind (or tow behind) lawn sweeper. The pull-behind is meant to attach to a riding lawn mower to pick up the lawn clippings. If you use a riding mower, a pull-behind option makes sense.

What will break down thatch?

The best way to get rid of thatch is to get it to decompose at ground-level by applying the enzymes and microbes contained in our liquid Biological Dethatcher.

Why is my lawn full of thatch?

By applying too much fertiliser to your turf, you can cause it to grow too fast for the natural soil fungi to destroy it, and thus thatch accumulates. It is okay for turf to have no thatch if you like firm turf, but your turf will suffer if the thatch layer grows too thick.

For best results, it is better to dethatch after a light rain or absent that, you’ve watered the lawn. Avoid dethatching when the soil is saturated after heavy rainfall.
