When To Power Rake Lawn Guide 2022


Does your lawn seem to have unwanted thatch buildup? While thatch can be beneficial, it can also be harmful once it gets too thick. The best solution to getting rid of thatch in a gentle and effective way is to power rake your lawn.

Power raking will also stimulate healthy lawn growth so it’s always a good gardening practice to keep in mind. 

Power raking should be done at specific times of year for best results. Keep reading to find out everything you need to know about power raking your lawn!

What Is The Purpose Of Power Raking?

Before I get into the details of when to power rake, let’s first understand what this practice of power raking is. 

Power raking helps remove unwanted thatch, which is dead turfgrass tissue and other organic matter developing between the soil surface and the grass level. Thatch occurs when there’s a lack of microbial activity in the soil. 

A thin layer of thatch is good because it insulates the soil and retains moisture. But a thick layer of thatch can be quite detrimental because it prevents water from reaching the soil and forces the grass to root in the thatch instead of the soil. In the summer, your lawn may not cope well if the grass is covered in thatch.

By removing thick layers of thatch, you allow your lawn to breathe easier and root deeper.

How can you know for sure whether this is what’s affecting your lawn? Thatch feels “springy” when you step on it, and if it’s gotten thicker than half an inch, you need to act fast to remove it before it stunts your lawn growth and health.

It might be tempting to get your lawn mower out to try and gather that dead grass and thatch build-up hanging around, but this won’t really solve the problem. Using a power rake will eliminate debris and dead material, which tends to build up between the lawn’s root system and the top layer of grass. 

Power rakes and powerful tools that get the job done faster and more efficiently than any other piece of equipment on the market. Keep in mind that since a power rake is such a powerful tool, if it’s not used correctly, it can cause damage to your lawn.

Dethatching is another alternative to power raking. This process involves using a lighter tool compared to a power rake, which is often preferred by professional landscapers. If you have a thin thatch layer to remove, dethatching may be an easier option for you. But if you have too much thatch to get through, power raking might be the way to go. 

When Should You Power Rake Your Lawn?

The best indicator to follow when deciding when you power rake your lawn is the type of grass you have. It is also important to note your grass’s growing season. Different types of grasses have varying growing seasons, which means that the ideal time to power rake them will differ.

For example, you should ideally power rake warm-season grasses, like rake Zoysia and Bermuda grass, in the early summer or late spring. Cool-season grasses should be power raked in the early fall. These include Kentucky blue grass, fescue and ryegrass.

Power Raking Vs Core Aeration: Which To Choose?

Power rakes use vertical tines on a revolving reel to remove thatch. Being as powerful as it is, power raking can be quite an aggressive practice that has the potential to damage your lawn by removing too much of the living turf. 

Core aeration, on the other hand, extracts slender soil plugs from lawns to relieve congestion due to foot traffic and is commonly known to be the safer of the two options. Soil aeration improves the efficiency of irrigation and increases the penetration of soil-applied pesticides. 

This video by YouTube user Silver Cymbal does a great job of explaining exactly what the process of core aeration involves and how to do it:

P.S. If you’re planning on overseeding your lawn but you aren’t sure whether it can be done without core aeration, check this out!

Choosing whether to power rake or core aerate is based on whether your lawn is suffering due to compaction or a thick thatch layer. It can be quite difficult to ascertain which it is, so to stay on the safe side, it is recommended that you core aerate first. If you’ve core aerated and the health of your lawn doesn’t seem to have improved, you should power rake. Removing thatch will likely solve the issue!

How Often Should I Power Rake?

You should power rake at least once a year to promote healthy grass roots and remove thatch build-up. Power raking is also great for improving the flow of air, water, and nutrients to the soil while stimulating healthy plant growth to give you lush, green grass.

What Time Of Year Is Best To Begin Dethatching Your Lawn?

The time of year that is best to begin dethatching your lawn is when it is actively growing and the soil is moderately moist. Warm-season grasses should ideally be dethatched in late spring or early summer. Cool-season grasses should be dethatched in early spring or early fall.

Should I Power Rake Or Aerate First?

You should power rake first and then aerate your lawn. Power raking will adequately prepare your lawn for aeration. You should ideally aerate your lawn five to seven days after you power rake so that your lawn has enough time to recover between the two procedures.

Now You Know When To Power Rake Your Lawn

Power raking your lawn isn’t something that’s done regularly like lawn mowing, but it is still a very essential aspect of lawn maintenance that’s sometimes forgotten about. You only need to power rake once a year to remove excess thatch and promote a healthy lawn.
