What are the Functions of Mulching Lawn Mowers?

Mulching is a technique for cutting your lawn without collecting the grass clippings and mulching them back into the lawn. A lawn mower equipped with either a mulching plug or a dedicated mulching mower finer chops the grass cuttings.

Mulching has the advantage of forcing grass clippings back into the lawn rather than collecting them. This saves time, is more ecologically friendly, and as the grass decomposes, it releases nitrogen and other nutrients into the soil, fertilising your lawn organically.

Decomposed grass also adds moisture to your garden because grass is 80 percent water. Mulched lawns are healthier, greener, thicker, and require less irrigation as a result.

So, what is mulching and why is it important to consider when buying a lawn mower?

I’ve examined a lot of lawn mowers over the years, and I’ve noticed a rising interest in mowers that can mulch grass cuttings instead of or in addition to collecting them. I get a lot of inquiries regarding these mulching mowers, as well as the process of mulching your grass in general.

There is a lot of confusing and contradictory information out there, which is especially true when publications are written outside of the UK. The advantages and disadvantages of whether or not mulching is the appropriate choice for you and your lawn will be influenced by highly unique variables in the UK, such as weather conditions.

British weather would not be complete without rain, and enough of it. Rain comes and goes, but it is rarely gone for an extended period of time. When you consider that wet summers are a way of life in the United Kingdom, the necessity of being prepared for rain in your garden becomes evident.

However, the last two summers in the UK have witnessed extremely dry spells lasting many months, causing lawns to dry out and turn into desolate patches of straw and dust.

A mulching mower can assist you in adjusting your mowing schedule to ensure that your grass is rain-ready, dry-ready, and mulch-friendly.

Mulching lawn mowers, on the other hand, may make a tremendous difference in keeping your lawn and garden area looking lush and bright all year – and I’ll show you how.

In light of the growing desire to be more ecologically friendly in our gardens by utilising organic methods, and the ways in which mulching can assist you do so, I’ve created this post to see if mulching your lawn is a feature worth considering when buying your next mower.

What is the purpose of mulching?

Mulching is a technique for trimming your lawn without collecting the grass clippings and leaving them to decay quickly in the soil. This process replenishes the soil with important nutrients (nitrogen) and moisture, resulting in a healthier, greener, and more dense lawn. Either a mower with a mulching function or a dedicated mulching mower will be required.

Mulching isn’t always a good idea, and I’ll explain why later, but if you do it, you’ll get the following benefits:- A healthier, greener, and more dense lawn Reduces thatch and moss Helps to prevent weeds and lawn disease Less likely to dry out in hotter periods Saves time emptying the collection bag (up to 30% faster) Environmentally friendly – uses less fertiliser

This is why mulching has been a popular topic in recent years, and the demand for mulching mowers has been gradually increasing.

Before you go out and buy a mulching mower, there are a few things to think about, as mulching isn’t always the greatest decision. Continue reading to discover more about mulching, as well as some of the challenges and situations in which cutting and collecting the cuttings is a better option.

Due to the wetter weather conditions in the UK, I believe that having a mower that can mulch as well as cut-and-collect is the ideal option (you can then choose what is best depending on your circumstances).

That isn’t to suggest that a dedicated mulching mower doesn’t offer its own set of benefits and functions. Later in this essay, I’ll go through the many sorts of mulching mowers.

Let’s take a quick look at how mulching works now that you know what it is and the benefits it provides.

Mulching Mowers: How Do They Work?

A mower with the capacity to mulch, as the name implies, is ideal for mulching your lawn. Rather of collecting grass clippings in a grass collection box, it is designed to allow them to seep back into the turf’s base.

The greatest mulching mowers will cut the grass finer and more effectively push it back into the soil. This enables you to maintain a continual mulch cycle and a 100% organic lawn care maintenance schedule, both of which are quite helpful to your grass, as we’ll see.

Why Mulch in the First Place?

The grass is cut once and driven through the grass collection chute into the collection bag when using a standard cut-and-collect mower. Assume the chute has been plugged with a mulching plug, and the cuttings are whirling about in the mower’s deck.

This cycle continues until the grass cuttings are so small that they are pushed deep into the lawn from the bottom of the mower. That’s all there is to it! A mulching mower works similarly to a large blender, slicing grass trimmings into smaller and smaller particles. What is the significance of this?

The smaller the cuts, the faster they disintegrate, releasing nutrients and water into the lawn. Smaller clippings allow them to penetrate deeper into the lawn, avoiding being picked up on shoes or bare feet and carried to walks and into the house.

Keep in mind that the longer the grass is, the harder it is for the mower to cut the clippings into smaller pieces. As a result, always adhere to the “one-third” guideline.

As with other lawn mowers, whether mulching or not, only cut one-third of the length of your lawn to ensure that your mulching mower does not get overworked and clogs up, pushing clumps of grass cuttings into the lawn.

When mulching any lawn, it’s usually a good idea to keep it from growing too long and to cut it frequently. It’s worth remembering that this regulation will apply even if you’re pruning and collecting to keep your lawn healthy.

Mulching is used to improve soil quality. It can do so in a variety of ways, including keeping the soil cool, adding nutrients, storing moisture during hotter periods, and keeping the soil fertile and healthy during rainy months, the latter of which is particularly crucial for UK lawn owners.

Is Mulching Beneficial to Your Lawn, and Why?

Yes, it’s as simple as that! Golf courses have been cutting fairways and greens without collecting grass clippings for decades. This is the same technique used to mulch your lawn. We all want a lawn that looks like a golf course green, so what greater mulching tip could there be?

Having a beautiful, green lawn might take a long time and be pricey. Many gardeners have given up and have hired a lawn management firm to treat their grass with chemicals on a regular basis.

This isn’t ideal because it’s pricey, it’s not ecologically friendly, and you’re still responsible for cutting the lawn on a regular basis.

Mulching allows you to mow your lawn as usual (saving time collecting and emptying grass clippings) while also organically fertilising (feeding) and protecting your lawn against moss, thatch, bugs, and disease.

The little grass particles are driven deep into your lawn, where they decay in a short time and release nutrients like nitrogen and phosphorus.

These nutrients are subsequently transmitted into the soil by microorganisms, providing organic fertilisation for your lawn without the need for costly lawn services or synthetic fertilisers.

Mulching is also safer for pets and children than synthetic fertilisers.

Because a blade of grass contains 80% water, this liquid is released into the soil, providing much-needed water reserves during the summer’s drier and hotter months.

There are some misconceptions about mulching causing thatch or moss in your lawn; however, this is simply not the case. More information about this can be found in the section below titled “Common mulching Myths.”

So, there’s no denying that mulching is beneficial to the health and appearance of your lawn.

When Should I Mulch My Lawn (And When Should I Not Mulch My Lawn)?

If the lawn is wet or very damp, the mulching mower, or any mower for that matter, will clog up and be unable to spread the cuttings freely, resulting in clumps of grass being dumped on the lawn (not good). It would be preferable to let the grass dry out for a day or two in this circumstance, or simply chop and gather the cuttings.

This is why I believe a mower that can cut and collect as well as mulch is a preferable choice for gardeners in the UK. You’ll be able to change your cutting method depending on the weather.

Mulching is most effective when the grass is reasonably short and dry. This means you’ll have to stick to a regular mowing schedule because you’ll only ever trim one-third of the grass at a time (more about how often you need to mulch later). If you let your grass grow for a few weeks before cutting it, mulching may not be the ideal solution for you.

Having said that, we are aware that cutting the lawn too short can also cause problems. Grass blades must collect as much light and nutrients as possible in order to save them for more difficult growing situations, such as drought.

Your lawn doesn’t have to be as neat as a golf course. That’s unreasonable for a lot of reasons, the most important of which being that golf courses have significantly more natural and financial resources at their disposal to help them achieve their goals.

When you have weeds in your lawn that are seeding, such as dandelions and/or crabgrass, mulching may not be the greatest option. It is preferable to address the weed problem first before mulching because mulching will simply expand the weed problem; instead, employ cut-and-collect until the weed problem is remedied.

If you have a problem with thatch or moss in your lawn, mulching may increase the problem, so address the problem first before mulching.

Having a mower that can mulch as well as cut-and-collect gives you the best of both worlds and guarantees you always have a beautiful lawn.


Are Mulching Mowers Beneficial to Your Lawn?

Because you don’t have to empty the grass collection box, a mulching lawn mower is a fantastic option for reducing total garden waste and time spent mowing your lawn. If you’re entrusted with cutting a large lawn, you won’t have to worry about regularly replacing the bag or making your way to the compost heap.

Another advantage of contemporary mulching mowers is that they reintroduce freshly cut grass to the lawn. If you’ve ever tried mulching, you’re aware that there are two potential drawbacks: unattractive clumps of grass and a lack of aeration if mulching in damp weather.

The former can make your lawn look a little unkempt and spotty, while the latter can limit air movement to your grass’s soil and roots, harming its health and perhaps promoting rot.

The secret to successful mulching is to use a mulching mower correctly and at the right time, resulting in a lush, green, and healthy lawn that will make your neighbours jealous. Not only that, but mulching your lawn while mowing will cut down on the time it takes to cut (no stopping to empty the grass box), while also giving all of the above-mentioned benefits to your lawn.

Mulching mowers are very vital in the United Kingdom because of our damp and variable weather. Excessive rain can make mulch heavier and more clingy, making it more difficult to move and separate, thus timing is key (see “When to Mulch” above).

Is it true that a Mulching Mower necessitates more frequent cutting?

In a nutshell, it depends on how frequently you mow your grass.

As previously said, you will not be able to mulch the lawn if you let the grass to grow too long. During the spring and summer, you’ll need to stick to a regular lawn-mowing and lawn-care plan.

So, how often should you mulch your grass in order to obtain the best results?

In the UK, grass should be cut on average once a week during the summer and less frequently depending on the climate and growth of the grass during other seasons. This can vary slightly depending on where you are in the UK, and you may need to trim as much as twice a week in some locations.

If you wish to mulch an entire large field in one go and only cut twice a year, mulching is not for you. Most of us, on the other hand, have much smaller lawns to maintain, so you’ll probably want to trim more frequently and stick to a schedule.

Many gardeners who opt to mulch do it on a weekly or biweekly basis, as seen by those aforementioned weekly trips to the compost pile. A mulching mower makes this even easier, because most of us mow the lawn once a week during the growth season anyhow, and these mowers mulch as they go, according to a recent poll.

It’s also worth noting that robotic mowers cut and mulch your grass on a daily basis by their very nature. So, if you really want the benefit of mulching with no effort on your side (after the initial set-up and installation), you might want to have a look at the top robotic lawn mowers now on the market.

The fact that your mower mulches as well as mows does not imply that you should mow your lawn more frequently; the guideline is that you should mow your lawn once a week, and mulching mowers are ideal for this. Furthermore, one of the benefits of using a mulching mower is that it simplifies the process.

Are There Any Negative Effects of Mulching?
Simply explained, there are no significant disadvantages to mulching. There’s no reason why mulching won’t deliver the benefits I’ve outlined if you stick to a cutting schedule and mulch when the conditions are right, as explained above.

You’ll pay a bit more for a mower with mulching capabilities, but the benefits greatly outweigh the extra expense. For instance, if you buy a Bosch Rotak 37 LI Ergoflex mower, the optional mulching plug costs roughly £15 and is widely available on Amazon. The Mountfield Princess34 corded mower, for example, costs roughly £100 and has mulching capability built in.

It’s easy to see why mulching mowers are getting more popular; there are very few drawbacks to mulching your grass if done correctly.

What Are the Best Mulching Lawn Mowers?

Many decisions must be considered when purchasing a new lawn mower, such as whether to go with a petrol, corded, cordless, or even robotic mower, and what deck size is required.

The good news is that mulching mowers don’t have to add to the stress of selecting the best lawn mower for your needs because they come in all of the above forms. Robotic mowers, by design, can only mulch grass clippings and are perfect since they mow for lengthy periods of time on a regular basis, ensuring that the grass never grows too long.
