In this guide you will learn everything you need to know about how mulch works.
It’s true, there are a lot of great reasons you should apply mulch.
However, there are four major functions that mulching the garden serves.
So without further ado, let’s jump right on in, and see how exactly mulch works, and why mulch is so important!
What is Mulch, Anyway?
There are a variety of mulches which vary in composition.
It is most commonly made from organic material such as:
Wood chips,
Bark chips.
Mulch can also be made from compost or manure, or inorganic substances like recycled tires. Whichever mulch you choose, spreading a few inches of mulch around your garden beds can be a great way to get the most out of your garden,
By spreading mulch around your trees, plants and garden beds, you will save yourself time and money. All while making your landscape look its best!
Why? Well here are four major functions of mulch.
Understanding How Mulch Works: The 4 Functions
Function 1: Mulch Prevents Erosion
Simply put, without mulch soil is vulnerable to the elements. Wind, rain, and even sprinklers can cause unprotected soil to erode, in no time at all.
Erosion causes many problems for your plants. Those problems have effects that can kill a plant or tree.
Worst of all, erosion depletes vital nutrients from the soil. Plants need a healthy diet in order to survive an thrive. Important nutrients like phosphorus and nitrogen are flushed out of the soil when no mulch or ground cover is present.
Mulch not only deters erosion, it provides much-needed nutrients for the soil as it breaks down. This is aided by the daily business of worms and other organisms.
No matter what climate you're in, your plants will need mulch.
Without mulch, you are wasting money:
For example, let's say you spread mulch in your garden beds which haven’t been mulched.
After only a rain or two 80% of the nutrients will be washed away. A mulched bed on the other hand is much better at retaining nutrients, and soil.
Function 2: Mulch Slows Evaporation
Nutrients are important, but so is water. Without mulch, soil is left to bake in the sun, which increases the rate of evaporation!
This is especially problematic for malnourished plants or plants with exposed roots.
Mulch corrects this problem by providing an excellent barrier. This barrier will prevent the sun from reaching the soil, and thus minimizes evaporation.
Best of all, mulch also acts like a sponge and absorbs water. Preventing it from running out of your garden beds.
Here's the catch, be sure to mulch properly. Mulching too thick, or too close to your plants can be just as devastating as no mulch at all.
If you want to keep your lovely mounded garden beds, mulching is your best way to keep your soil from eroding.
Function 3: Mulch Prevents Weed Growth
When weed seeds are exposed to the sun, they germinate!
However, when they are buried beneath a layer of mulch, they do not germinate. It almost seems too good to be true, but mulch greatly reduces the growth of weeds.
Here's the deal, if you have spent long hours weeding your flower beds, you really must do yourself the favor of properly mulching before you call the job finished.
If not, the weeds will be back before you know it, and you'll have a job to do all over again.
Of course, weeds will eventually come back. But they will be much far and fewer between when you mulch your garden beds. Additionally, weeds growing in a layer of mulch are generally easier to pull.
Function 4: Mulch Balances Ground Temperature
The final function that mulch serves is balancing temperature extremes.
No matter the climate, hot or cold. Mulch prevents large ground temperature swings which can be harmful to plants.
In warm climates, mulch keeps the soil from getting to hot, and dehydrating or burning plants.
In cold climates, mulch keeps the ground warmer, and prevents the ground from freezing, or at least prevent it from freezing as deeply. That is why it is a good idea to mulch your garden in spring and fall in colder climates.
What is Mulch Mowing?
Mulch mowing refers to a lawn mowing technique that cuts grass blades into fine pieces, which are then left on the lawn. This process uses a special mulching mower or a mulching blade attachment.
This method enhances soil health, promotes moisture retention, and reduces the need for additional fertilizers, making it an eco-friendly and efficient lawn care practice.
How Does Mulch Benefit My Garden?
Mulch offers multiple benefits: it prevents soil erosion, slows down evaporation, inhibits weed growth, and balances ground temperature. Utilizing mulch in your garden beds ensures nutrient retention, water conservation, weed control, and protection against temperature extremes, making it an essential component for a healthy garden.
When is the Best Time to Apply Mulch in My Garden?
The ideal time to mulch your garden is during mid to late spring, especially in colder climates. This timing ensures that your plants are protected against extreme temperatures and are well-nourished throughout the growing season.
How Thick Should the Mulch Layer Be in My Garden?
A layer of mulch should be approximately a few inches thick, 2-3 inches is sufficient. However, it's important to avoid over-mulching or piling it too close to plant stems to prevent potential issues like root rot or pest infestation.
Is mulch necessary for all climates?
Yes, mulch is beneficial in all climates, providing essential protection and nutrients to soil and plants. It's a key element for garden health, regardless of your location's specific weather conditions.
A Final Word From Your Yard: I Want To Be Beautiful
This comprehensive guide on mulching covers all aspects of how and why to use mulch in your garden.
Mulch, made from organic materials like leaves, wood chips, or inorganic substances, serves four key functions in your garden: preventing erosion, slowing evaporation, inhibiting weed growth, and balancing ground temperatures. It's vital for nutrient retention, water conservation, and protecting plants against temperature extremes.
Ideal mulching time is mid to late spring, with a recommended thickness of 2-3 inches. Suitable for all climates, mulch is a must-have for a healthy, beautiful garden.
