Lawn Scalping is not your typical cut from your lawn care routine. Don’t let that scare you. It’s more than just a quick trim to your lawn. It’s a nice bold haircut for your grass. This starts with mowing your grass shorter than usual, often removing one-third of the grass blade at the time of scalping. Doing this promotes a healthier lawn.
When should I scalp my lawn?
Choosing the right moment for lawn scalping will make an impacting different in the looks and health of the lawn. So when is the best time to scalp my lawn? The best time to scalp your lawn is between late winter and early spring. This is typically between February through March.
Remember there is one very important rule to never forget, you MUST wait until after the late spring freeze. If you do it before it will cause damage to the roots of your lawn and affect the recovery and growth.
Take into consideration, you should NOT delay the scalping process until your grass begins to grow. The perfect timing is when the grass is still in its dormancy conditions: dry and cool.
What is the benefit of lawn scalping?
The list can go on and on about the benefits that lawn scalping offers your lawn. Here are some of the main benefits that will help your lawn with scalping.
- Thatch is a layer of decaying grass, roots, and organic material that can suffocate your lawn. Scalping helps minimize thatch accumulation, improving the flow of water, air, and nutrients into the soil. This is known as reducing thatch buildup.
- If you’re overseeding your lawn to cover bare patches or introduce new grass types, scalping helps expose the soil, giving your freshly planted seeds better contact with the ground. This boosts their chances of germinating and establishing strong growth. This is known as enhanced overfeeding.
- Once the grass is scalped, the shorter turf helps fertilizers penetrate more deeply into the soil, ensuring it absorbs the necessary nutrients and pre-emergent herbicides effectively. This is known as absorption improvement.
- Scalping removes dead grass and debris, helping to reduce the chances of fungal infections and pest problems that tend to flourish in decaying organic material. This is protection against any diseases.
- Scalping your lawn can help stop weeds from sprouting. By clearing away dead grass and debris, you eliminate spaces where weeds might take root, helping to maintain a clean and well-kept lawn. Natures way of weed prevention.
- Scalping enables more sunlight to reach the soil, creating a warmer and more favorable environment that encourages your grass to begin growing earlier in the season.
Why should I not scalp my lawn?
Although lawn scalping provides many benefits, of course not without some hold backs. Let us explain:
- Timing is important: You can cause your lawn extensive stress if you decide to scalp too early while the cold frost is still on your lawn which will affect its ability to grow.
- Not for cool season grasses: Grasses that have different growth patterns like fescue, which many of us have, is not recommended.
- Lawn scalping, which involves mowing the grass very short (often down to around 1/2 to 1 inch) to promote healthier growth or remove thatch, can be beneficial for warm-season grasses like Bermuda and Zoysiagrass, which spread through rhizomes (underground stems). These grasses can recover quickly after scalping because the rhizomes store energy and can sprout new growth even if the top growth is cut back significantly. However, for grasses that spread primarily by stolons (above-ground runners), such as centipedegrass, buffalograss, and carpetgrass, scalping can be much more risky. These grasses rely on stolons to spread and establish new growth. When you cut them too short, it can damage the stolons or remove them completely, which may hinder the grass’s ability to recover and spread. In some cases, scalping can lead to thinning or even large bare patches in the lawn.
- Intense labor work: If you have a larger lawn, that means multiple passing with a reel mower to get it to the correct size.
- No clippings left behind: You can’t leave the grass clippings on your lawn, this means proper disposal is required. Those clippings have dead grass blades and thatch that builds up which will go against any growth.
How do I scalp my lawn?
Now that you’ve gone over the timing and have gone over the benefit, let’s learn the how to.
- We cannot stress enough how important the timing to scalp is. Good way to measure is when temperature is just below 60-65 degrees Fahrenheit ( since this is the temperature that Bermuda and Zoysiagrass begin to grow). Begin with your reel mower that has sharp blades. NEVER DULL! It was cause stress to your lawn if you have dull blades. Attach a grass catching bag to your mower to make sure those clippings are not left behind.
- Properly adjust the height for the blades to begin. It should be between 1/2 inch to 1 inch. You do not want to cut too close to the soil, so make sure you double check your height.
- Begin your scalping. Depending on your lawn size it may be best to make multiple passings to ensure an even cut. As the process takes a few hours, of course depending on the lawn size, be sure to be patient.
However, it’s important to remember that scalping should only be done once or twice a year, and it’s not recommended for all grass types. If you’re unsure whether scalping is right for your lawn, consult a professional or your local lawn service.
How often can I scalp my lawn?
You can trim your lawn down to the soil once a year, usually in late winter or early spring. This yearly procedure helps refresh your grass and get it ready for the upcoming growing season. Doing it more often can put unnecessary stress on the turf, so it’s recommended to limit this practice to just once annually.
Can I scalp Fescue?
No, you should avoid scalping Kentucky bluegrass or any other cool-season grasses, such as fescue. Scalping is better suited for warm-season grasses, particularly Bermudagrass and Zoysia. Cool-season grasses have distinct growth habits and do not respond well to the same scalping method.
Is scalping the same as de-thatching?
No, scalping is different from dethatching. Scalping means cutting your grass very short to encourage new growth in the spring. On the other hand, dethatching is the process of removing the build-up of dead grass, roots, and stems that forms between the soil and the grass blades. While both techniques help improve lawn health, they each serve a unique purpose in lawn care.
Ask a professional
In the pursuit of a flawless lawn, scalping can be an effective technique for homeowners. However, the success of this approach depends largely on timing. If you miscalculate the right moment to scalp, it can stress your grass and stunt its growth, ultimately preventing you from achieving the lush, healthy lawn you desire.
