How to Cut Tall Grass

Are you having problems with the tall grasses in your lawn? Are you wondering should you cut them? Then the information below on how to cut tall grass will surely help you achieve the desired results.

Maintaining your lawn is one of the must-to-do things to make your house to look good. Unfortunately sometimes, due to the busy schedules, gardeners tend to forget to mow their lawns. This will result in longer and harder-to-cut grass. Don’t fret because you can eventually cut them accurately.

Leaving the grasses in your lawn grow tall can pose great problems to the lawn’s health. They can suffocate the lawn, which will then weaken other grasses. Therefore, cutting them as soon as possible is essential.


Some gardeners end up hiring a professional to handle their tall grasses. But what they don’t know is that they can do this task themselves. With the right tools, you can tackle this tedious task easily in no time.

Tips on Cutting Tall Grasses in Your Lawn

1. Setting the Deck’s Height

The majority of the lawnmower decks have a 4 inches height for cutting. But if you are dealing with longer than 4 inches grasses, this can be difficult. You can raise the deck to the highest setting and start cutting. Just make sure that you are cutting only 1/3 the total length of the mower's blade.

Doing this will reduce the blade’s stress when it comes to cutting your grasses. Once you are done, you can repeat the process until they reach the wanted height.

2. Cutting Steady and Slow

When it comes to cutting tall grasses, you need to make sure that you are doing it steadily and slowly. This will avoid stressing your lawnmower too much. You can rush mowing your lawn if the grasses are shorter. Otherwise, slowing down is a preferred option.

3. Using the Right Mower Blades

There may be a lot of mower blades in the market, but choosing a hi-lift one is ideal. This can effectively help tackle all the tall grass that you have in your lawn.

Tips on Cutting Tall Grasses Using a Small Lawnmower

Now, if you are dealing with tall grasses with only a small lawnmower, do not panic we can make it work properly. Below are some of the useful tips:

1. Preparing Your Small Lawn mower

You can make your lawnmower by checking the blade if it is sharp enough to cut grasses. You can always sharpen it with a file if needed, but if it has already been damaged, then replacing it is your best option.

2. Cleaning Your Lawn from Debris

The next thing that you need to do is start walking through your lawn to look for debris. You need to get rid of every debris as they can damage your blade badly. Also, you may use a lawn sweeper to help you get rid of all the waste that you might not be able to see.

3. Cutting Your Tall Grasses

Once you’re done cleaning your lawn, you can now start cutting the tall grasses. You can do this by cutting them between 4 to 5 inches in length. You might either use a weed trimmer or whacker for this task. If you have a large lawn, then you should expect to work for at least a few hours.

4. Mowing the Remaining Grasses

Set the small lawn mower to its mulch or bagging setting (or use a dedicated mulching mower). The blade, on the other hand, should be at its highest possible setting. Once done, you can start working in smaller rows. Just make sure to clean the blades after each row to avoid clogging it.
