Are you seeking information about how to get your garden ready for the following year? If this is the case, you must know about compost and mulch. These nutrient-rich elements, if applied properly, can assist you in cultivating plants that are both stronger and healthier. Mulch and compost each have their own set of benefits despite the fact that many people mistakenly believe they are the same thing.
When you have a greater grasp of how they are distinct and comparable, you will be able to make an educated choice regarding your garden. To assist you in developing a garden that is both robust and productive, the following subjects will be discussed.
What Is Mulch?
Mulch is any substance used to cover the soil. While organic matter is inherent to the definition of compost, not all mulch is considered organic. Wood chips or shavings and bark made from hardwood and softwood are the most common types of mulch that may be purchased in bulk or bags at garden centres.
Additionally, mulch can be used as mulch for buckwheat hulls, grass clippings, cocoa shells, tree leaves, rice hulls, and other crop residues.
Rubber, plastic sheeting, and geotextiles like landscape fabric, cardstock, and newspaper are examples of synthetic, man-made mulches. Only the latter two break down, leaving behind harmless byproducts, but plastic slowly degrades into microplastics that pollute the environment.
The third category of mulches consists of non-biodegradable elements found in nature, such as broken pebbles, seashells, stone chips, gravel, and slate. These mulches are all natural.
Mulch Applications
Mulch is applied to the soil in garden beds and landscaping to serve as a moisture barrier, a weed barrier, and an aesthetic enhancer. Mulch prevents the soil from drying up as quickly by trapping moisture in it. A thicker, denser mulch is preferable when stifling weed growth, but not all mulches are created equal. Finally, a flower bed that has been mulched tends to look neater and more organised than one that has not, though this is a matter of taste.
Common Mulch Types
Mulch comes in various forms, although it can be broadly classified as organic or inorganic.
Organic Mulches
Mulch that meets the criteria for “organic” is either currently living or was at one time alive. This organic mulch decomposes over time to enrich the soil.
Mulches made of wood, such as pine bark mulch, wood chips, hardwood mulch, and cedar mulch, are the most widely used.
Other types of organic mulch include:
- Hay or Straw
- Leaf Litter
- Grass clippings
- Pine Straw is made from dried pine needles.
Inorganic Mulches
Compared to the living matter in organic mulch, the inorganic variety does not break down. They don’t improve soil quality, but they have their uses in the garden.
The most popular types of inorganic mulch are:
- Rubber mulch
- Landscape Fabric
- Rocks/Stones/Gravel
- Black Plastic Sheeting
The Advantages Of Using Mulch In The Garden
When it comes to a vegetable garden or flower beds, utilising mulch has many advantageous effects.
Nutrients
Mulch can be made from various decomposing organic and inorganic materials. Mulch can be made from various materials, including landscape fabric, used tyres and wood chips, rocks, bark, and pine needles. Combining these components may enhance your garden’s plants and promote their health and vitality.
Soil Moisture Retention
Adding mulch to a garden helps prevent soil from drying out quickly. This means that water remains in the soil for a significantly longer period of time to hydrate plant roots than it would if the soil were bare. This is particularly significant for sandy soils, which have a propensity to become dry rather quickly. The amount of water that must be applied to the soil in a garden mulched appropriately will be reduced. That is wonderful news not only for the plants but also for you.
Reduces The Growth Of Weeds
Add some quality mulch to your garden if you’d rather not spend time picking weeds. The use of mulch is an effective approach to weed control. It serves as a natural barrier that prevents sunlight from reaching weed seeds and suffocates them as they attempt to germinate. Some weed growth may still occur, but it will be significantly less prevalent than in a garden with bare soil.
Enhance Soil Health
The health of the soil will gradually improve thanks to the use of organic mulch. The organic matter will be added to the soil as the mulch decomposes and becomes a part of the soil. As it decomposes, it will entice organisms, such as worms, insects, and beneficial microorganisms, which will further improve the quality of the soil.
Erosion Protection
Mulch comprises several layers of diverse organic materials, and its many layers help to do two things: retain moisture and prevent erosion. Your garden will be safe from soil erosion and other rain-related problems thanks to its ability to slow the flow of rainwater and act as a barrier.
Mulch in the garden can also act as a barrier against the weather. When there’s a lot of wind, rain, or hail, the mulch keeps the soil in place. Mulch used on sandy soil will keep it from washing away, and mulch applied on top of clay soil will decrease water runoff by allowing the claymore time to absorb the water.
Plant Disease Prevention
It is possible to lessen the amount of dirt and water splashed onto the plant leaves by applying a layer of quality mulch on top of the bare soil. The spread of bacterial and fungal illnesses is slowed down as a result of this measure.
Controls Soil Temperature
During the hotter months of the year, mulch is able to assist in preventing the soil from overheating. The top layer of soil is concealed by the mulch applied to a garden when… This serves to naturally shade the ground and insulate it, both of which contribute to maintaining an appropriate temperature for the soil.
Increases The Growing Season
In the same way that mulch helps prevent the soil from overheating during the summer, it can also help to retain heat during the winter. Mulch acts as an insulator by covering the soil’s surface. This helps warm the soil, allowing you to continue growing through the colder months.
What Is Compost?
Compost is an organic material that has decomposed to a certain extent. Anything that has decomposed naturally and does not pose a health risk can be composted, including food scraps, grass clippings, leaves, manure, weeds, and plant debris.
Decomposition of compost can take anywhere from two weeks to two years, depending on the material and a number of other factors. Having just the right amount of green and brown materials in a compost pile. Also beneficial are worms and bacteria that aid in composting and the proper amount of moisture, turning the pile, aeration, size, temperature, and ambient conditions.
When compost has decomposed completely, it is known as humus. None of the source materials are recognisable in their current forms. Compost that has reached maturity is crumbly, dark brown, and smells earthy.
Composting Applications
You can’t get more recycled than compost. Compost that has had time to mature adds nutrients to the soil in a form that plants may easily use. However, more than simply using compost as a fertiliser in a garden is required because the compost’s nutrient makeup depends on the original components, especially in a vegetable garden, where the soil is used yearly for new crops. In addition, fertiliser should be used strategically to ensure optimal growth.
Compost also acts as a soil amendment, enhancing soil health. Mature compost and other forms of organic matter break up the compact nature of clay soils, making them more suitable for plant growth. Additionally, organic matter is beneficial to sandy soils because it assists the soil in retaining water and nutrients and makes it less susceptible to erosion.
The Advantages Of Using Compost In Your Garden
Most people know that compost has some value, but let’s dig into why. You may be surprised to learn that the benefits extend beyond your backyard.
Compost Holds Moisture
One pound of compost can increase water retention by 33 pounds, or 4 gallons, when added to standard soil. Add 5 pounds of compost to 100 pounds of soil, and it will be able to contain twice as much weight or 25 gallons of water. The soil of any type may benefit from compost, though.
Soil Microbes Are Fed By Compost
Just as acidophilus in yoghurt is beneficial to human health, so too are the bacteria in soil. Despite the complexity of their role, they are essential to the soil since plants cannot absorb nutrients without them.
Microbes are living organisms that break down organic matter like compost to produce nutrients like nitrogen, oxygen, potassium, hydrogen, carbon, phosphorus, and trace minerals that we may use to nourish our plants. Composting is a great way for gardeners to ensure their soil microbes never go hungry.
It is common practice to add a shovelful of garden soil to a compost bin in order to boost the microbial population. Even though they are naturally present everywhere (not only in soil), adding them to a garden speeds up decaying.
It Lessens Erosion
Do you have a feared slope at home? You need to spread compost around your plants with deep roots so that it can soak up any excess water that might otherwise cause the slope to erode over time. This is becoming an increasingly common practice on the slopes of hillsides close to motorways and highways.
Microbes Are Increased
In addition to the things described, bacteria already exist in compost because they are the organisms responsible for the first breakdown of the food, leaves, and other items in the bin. This helps to promote the growth of new microorganisms, which in turn has assisted in the decomposition of the scraps of leaf and garden debris.
Compost Contains Humus
When organic matter decomposes, it often produces humus. Compost yields humus after the decomposition process is complete.
Although humus does provide some nutrients, especially carbon and phosphorus, it needs more nitrogen. The ability of humus to absorb water is its most notable benefit. Both are important for a garden’s health since they provide different plant nutrients. Most topsoil will have humus as one of its main components.
Composting Can Lower Expenses
Compost is nutrient-dense; thus, there is no need to purchase fertiliser; consequently, less irrigation results in lower water expenditures. It also reduces the need for pesticide use. Keep in mind that many cities provide citizens with free compost pick-up days each spring. Look at the local government sites for any information you need.
Compost Lowers Storm Water Runoff
Compost acts as a sponge, soaking up rainwater and reducing water flow into storm drains. Runoff, which includes rainwater and water from an excessive amount of irrigation, collects a variety of contaminants on its way to the ocean. These contaminants include grass clippings, garbage, pesticides, and others damaging to marine life.
Compost Improves Soil Structure And Porosity
Soil structure refers to the degree to which inorganic particles and decomposed organic materials (like compost and humus) hold together. Soil with a good structure is crumbly and full of air holes, making it easy to work.
Plants have trouble flourishing on sandy soil because the porous substance absorbs precipitation. A sponge-like structure can be created by combining sand with compost, allowing more water and nutrients to be retained. In contrast, compost creates air holes between the clay soil particles, normally impermeable to nutrients and moisture. Compost is sometimes called a soil conditioner since it improves the soil quality of almost any type.
Compost Helps Prevent Disease
Soil microorganisms promote a wide variety of advantageous processes, such as destroying plant and human pathogens and reducing sickness. Compost is often used to prevent root rot. Science has advanced to the point where scientists can alter compost to include specialised bacteria that tackle crop-specific illnesses in large-scale agricultural settings.
By Composting, Waste Is Kept Out Of Landfills
Composting allows for the recycling of waste products that would otherwise be discarded, extending the useful life of landfills and reducing the workload of governments responsible for trash collection.
Can Mulch And Compost Be Used Together?
Mulch and compost serve different purposes (soil fertilisation and amendment) and should not be used interchangeably.
Mulches made from organic materials have the potential to improve soil quality by adding organic matter and nutrients as they decompose. Woody materials like bark mulch have a very slow decomposition rate. However, the microorganisms in the soil require nitrogen to complete the decomposition of grass clippings and other new plant debris, which results in a higher decomposition rate. They steal it from any plants in the area at that time of day. Chlorosis, a sign of plant stress, can result. For the same reason, compost should not be added to the soil until it has had ample time to break down.
Using mulch made of other organic materials that have yet to decompose entirely can present similar challenges. If you pile up a bunch of leaves without first slicing them up, the air and water won’t get to the soil. Plants in the area may become infected with fungi or have root rot due to the excess wetness.
Conclusion
Mulch and compost are essential components in preparing your garden for the following year. Mulch is a substance used to cover the soil, with organic matter being inherent to compost. Common types include wood chips, bark, buckwheat hulls, grass clippings, cocoa shells, tree leaves, rice hulls, and other crop residues. Synthetic mulches include rubber, plastic sheeting, and geotextiles. Non-biodegradable elements like broken pebbles, seashells, stone chips, gravel, and slate are also natural.
Mulch is applied to soil in garden beds and landscaping to serve as a moisture barrier, weed barrier, and aesthetic enhancer. Organic mulch, which is either currently living or was once alive, decomposes over time to enrich the soil. Inorganic mulch, on the other hand, does not break down but has its uses in the garden. Popular types of inorganic mulch include rubber mulch, landscape fabric, rocks/stones/gravel, and black plastic sheeting.
Mulch has several advantages in the garden, including nutrient retention, soil moisture retention, and aesthetic appeal. By understanding the differences between mulch and compost, you can make an educated choice for your garden.
