Suspect your lawn may need to be dethatched? Before you proceed you should know that not every lawn requires power raking or “dethatching”. However, whenever thatch has built up in the lawn you should strongly consider it. Thatch is harmful to your turf and there comes a point when getting rid of that thatch becomes essential for your yard’s health. Here is some important information to consider if you are thinking about having your lawn dethatched.
When to Dethatch Your Lawn
Before you do anything, you should check to see how thick your lawn’s thatch layer is. You can do this by taking a spade or a garden trowel and digging out a small wedge from the soil. You can then get an idea of just how much thatch is present. If the layer of thatch exceeds 2 inches, then it is time to consider dethatching your lawn or hiring a Mission Property Maintenance to take care of it for you. You may have already noticed the signs before testing such as weak growth and dull grass color.
Keep in mind, lawn services such as aerating, overseeding, and dethatching should be done during the cooler seasons which means the turf is in peak growing season. Kentucky bluegrass is the most prominent grass type this usually means in the Spring or Fall. You want to do it during this time of the year because the active grass growth is necessary for the instant and speedy recovery of the lawn.
One essential thing to keep in mind is that you should never dethatch your lawn when it is under stress or dormant which lawns usually are here in the middle of Summer. The process of dethatching a lawn at this time can cause damage to your yard which can takes months or even years to recover.
Customers sometimes confuse the difference between de-thatching their lawn and having it aerated. It is important to keep in mind that these are two completely different process’ and each serves its own purpose in the overall health of your lawn. Lawn aeration removes 3” plugs from the soil that does include the thatch layer, but these cores are only pulled sporadically throughout the yard. Aeration is not the best option for removing thatch, but it does create a clear path for water, nutrients, and oxygen to reach deeper into the soil. Performing the two services in tandem will yield the best result as aerating loosens up compacted soil and turf therefore helping to prepare the lawn for dethatching. This also helps speed up the breakdown of existing thatch. Learn more about The Benefits of Lawn Aeration.
How to Dethatch Your Lawn
When it comes to removing the thatch from your lawn, we usually recommended calling a professional lawn service because of the backbreaking labor and expensive equipment that is required. Excessive thatch can require more than one dethatching because attempting to remove it all at once can result in damage to the grass roots.
Here are the three common ways of Dethatching a lawn.
⦁ Manual Dethatching: You can purchase dethatching rakes which are short tined rakes that are specifically designed to dig deep into your turf and pull out the thatch. This is a cheap option when there is only light thatch but be prepared, it is hard work.
⦁ Power Rakes: Power rakes are the next step up and by far the most common piece of equipment used. Power Rakes are more like lawn mowers that have rotating rake-like tines that go deep into the turf and pull out the thatch. Before using a power rake, you will want to make sure that your lawn is healthy enough to recover.
⦁ Vertical Mowers: These are also known as verticutters as they have vertical blades that go deep into the soil and pull out the thatch. These are usually only used when thatch layers are extremely thick. Vertical mowers are ideal for lawns that are in need of renovation as you can adjust the blades depth and pull up most of the top layer of nutrient deprived soil as well.
