Organic mulching is a type of mulching that uses organic materials to create a layer of protection for your plants. Mulch helps prevent soil erosion and water loss while improving soil fertility and aeration. Organic mulches also help protect plants from pests and diseases by keeping the soil temperature cooler in the summer and warmer in the winter.
There are different types of organic mulching. Organic mulches are made up of materials such as straw, grass clippings, and composted leaves. These materials decompose over time, which adds nutrients back into the soil. Organic mulches can be applied to bare ground or existing plantings.
There are many benefits of organic mulching. Here are some of them:
- It retains moisture in the soil, which helps plants grow better.
- It prevents weeds from growing, so you can spend less time weeding the garden or farm.
- The nutrients in the mulch feed your plants over time, allowing them to grow stronger and more resistant to disease.
- Organic mulches also help prevent erosion by holding down the soil so it doesn’t wash away as easily during heavy rains or during periods without rain when water needs to be released from the soil slowly so it doesn’t run off quickly and cause erosion problems.
- Organic mulches absorb rainwater. This prevents runoff and erosion, which can damage nearby property such as driveways or sidewalks. It also keeps water off your plants so they donβt get flooded out during heavy rains.
- Organic mulches help to keep the soil cool. The insulation effect created by organic mulch helps keep soil temperatures lower than surrounding areas during hot weather months. This allows roots to breathe without being exposed to extreme temperatures that could damage them permanently when they are young or even kill them if they are older plants with established root systems.
What is mulching?
Mulching is the process of covering bare soil with a layer of material that will protect it from erosion, conserve moisture and improve soil fertility.
When applied correctly, mulches reduce weeds and improve the soilβs ability to retain moisture and nutrients.
Mulches can be organic (such as leaves or grass clippings) or inorganic (plastic sheeting or landscape fabric).
Inorganic Mulches
Inorganic mulches are manufactured from materials that do not decompose, such as plastic and other synthetic materials. They provide a barrier to weeds, support plant growth, and help retain soil moisture. Inorganic mulches include landscape fabrics, gravel, rock, and synthetic products such as landscape cloth or plastic sheeting.
Inorganic mulches are made from items that are not organic, such as stone, gravel, and concrete. Inorganic mulches are often used around trees and shrubs because they help retain moisture and prevent weeds from growing. They also help to keep the soil cool during hot weather.
Inorganic mulches come in many different textures and colors, so you can find one that suits your landscape design needs. They are easy to install, but they do need to be replaced every few years due to weathering or decomposition.
Organic mulches
Organic mulches are materials used to prevent weed growth and improve soil health. These materials include bark, compost, and other materials that break down into the soil over time.
Organic mulches are used to keep weeds from growing in your garden or landscape. They also help retain moisture in the soil and keep the soil temperature even, which helps plants grow better. The mulch also prevents soil erosion during heavy rains and minimizes evaporation during dry periods of the year.
Organic mulches include straw, hay, grass clippings, leaves, sawdust, and wood chips. The wood chips should be chipped by a shredder so they don’t leave any sharp edges on them that could cut into your plants’ roots when you water them or when you work around them with tools or hands.
When choosing an organic mulch for your landscape, make sure it’s not too thick because it can cause drainage problems for plants as well as create an environment for diseases to grow such as damping off or root rot in seedlings or transplants from lack of oxygen circulation in the root zone of newly planted trees and shrubs due to poor drainage conditions caused by excessive organic matter decomposition
Benefits of organic mulching
Here are some of the benefits of organic mulching:
Boost your soil’s organic matter content
Organic mulches enrich your soil with organic matter as they decompose. When the micro-and macro-organisms in your soil rise to the top for a snack, they carry that organic material back down into your soil with them.
Eliminate weeds
It keeps the soil shaded by applying organic mulch. Since most weed seeds require light to germinate, this inhibits them from growing. Mulch also makes it much simpler to pull the few weeds that do emerge since it keeps the soil loose and moist.
Makes your garden appear more polished
Mulch fills in the gaps surrounding plants to give your yard a polished appearance.
Shield trees from mowing equipment and weed eaters
By putting organic mulch around trees that are positioned on lawns, you can prevent damage to your lawnmower or trimmer.
Prevent topsoil erosion
Topsoil is prevented from washing away by organic mulches because they slow down the fall of water during rain.
Keeps your vegetation tidy
Natural mulches aid in lowering soil splashback onto plants, which decreases soil-borne plant diseases.
Guard your soil against temperature changes
Mulch made of organic materials insulates. It can prevent plants from rising out of the ground in the winter and will keep your soil cooler in the summer.
Since organic mulch will stop your soil from warming up, it might not be the ideal option for your heat-loving veggies if you reside in a chilly region. The best option would be synthetic mulch.
Types of organic mulching
Below are the types of organic mulching:
Dry leaves
Collect tons of dry, autumn leaves, and utilize them as soon as you can in your vegetable garden. Dry leaves can be used as traditional mulch, covering the soil like a blanket, or you can bury them beneath the ground in a garden bed, where they will break down throughout the winter. You’ll have lovely, humus-rich soil for gardening come spring.
Alternatively, use them as a top layer of mulch while the vegetable plants are still growing and then bury them after the crops have been harvested.
Grass clipping
You are missing out a lot if you are not taking advantage of grass clippings. Grass clippings degrade quite quickly. The speedy decomposition of grass clippings has the beneficial side effect of warming the soil, which is perfect for the spring vegetable garden.
Keep the layer of grass clippings used as mulch around 4 inches; if it is stacked much higher, the grass will “mat” and suffer from a lack of air (anaerobic). Which implies that it will emit an unpleasant smell.
Compost
Compost functions in the same manner as any other kind of mulch, improving soil texture, tilth, and nutrients that seep right into the ground. For the best mulch for your vegetable garden, use a lot of it from your compost bin (or pile).
Straw and seedless hay
Both straw and seedless hay are effective mulches, though neither would be visually appealing if used to cover an ornamental foundation planting. For the vegetable garden, straw and seedless hay are fantastic but be careful to pile it on thick.
Thin layers tend to blow away quickly.
Wood chips or shredded bark
Both wood chips and shredded bark are common mulches, but because they are both robust materials that decompose slowly, certain gardens should be taken into consideration. For instance, I don’t think wood mulches are the ideal choice for an annual vegetable or flower garden that will be dug up and replanted numerous times a year.
For a perennial garden bed or shrubby foundation landscaping, wood pieces are unbeatable.
Living mulch
The term “living mulch” is frequently used to describe cover crops that are planted in a vacant vegetable bed to prepare for the upcoming season. The living mulch, on the other hand, is a crop that can be cultivated concurrently with the primary vegetable crops throughout the same growing season.
Veggies with vines, like pumpkins, or plants that spread widely, like potato plants, can be utilized as mulch for other garden vegetables. In addition to shading out and smothering weeds, pumpkins, squash, melons, zucchini, and cucumbers also help to bind the soil to the ground and prolong soil moisture. Plant these trailing vegetables alongside the taller plants, such as maize, tomatoes, sunflowers, and pepper plants.
As a live mulch, loose-leaf lettuce can be a wonderful option. As a powerful weed barrier, plant it around artichokes, onions, carrots, broccoli, cabbage, and beets. Because lettuce consumes very little food, it doesn’t pose a significant threat to the other food crops.
A mulched garden requires less weeding and watering, and as a result, will produce the most fruit possible.
Which crops are used in organic mulching?
There are a variety of natural mulches available, with old hay, pine straw, and hardwood bark mulch is the most well-liked. Which option is best for your garden?
Using hardwood bark mulch
Many people cultivate plants in their gardens that like neutral to sweet soil (alkaline). The best mulch for those plants is hardwood bark mulch. It breaks down into rich, fragrant, black dirt and looks wonderfully organized as it does so. Additionally, the finest mulch for soil improvement is hardwood bark. The issue is that it is pricey, especially if you purchase it from a garden center (and they aren’t even big bags).
Using pine straw mulch
Pine straw works well to control weed growth. It has a propensity to form a thick mat. Pine straw isn’t appropriate for every garden, though. Your soil may become acidic over time, making it difficult to grow anything. Many plants prefer acidic soil. Pine straw is not only acceptable, it’s ideal if the majority of the plants in your flower bed are those that thrive in acid.
Using hay as a natural mulch
On the other hand, used hay is incredibly cheap. Farmers cannot feed their animals with hay that has spoiled due to water damage since it could kill the animals. But if you’re a gardener, your garden needs that damaged hay. Your plants will likely prefer it to the unspoiled, fresh material, and your vegetable garden will likely favor it over hardwood bark mulch. A whole bale of damaged hay is frequently available for only a few dollars.
Of course, the fact that old hay is formed of grass is a concern (or grains). In a garden, the grass is a weed, and that hay is bursting with seeds of the same species as well as other weeds that may have been wrapped up with it. So what does a gardener do? Ruth Stout offers a fairly straightforward remedy in her ostensibly well-known “No Work Garden Book”: simply add extra hay. Even its weeds cannot penetrate hay placed around plants to a depth of about a foot (31 cm), which is too thick. It’s an excellent remedy for the vegetable beds (and it does work).
However, it has the undesirable consequence of making the flower beds look messy, and a messy flower garden might as well be overrun with weeds.
What are the disadvantages of organic mulching?
- There might not be any mulch available.
- Mulching requires a lot of labor.
- It might spread new pathogens and pests across a field.
- There is a fire risk with the dried organic mulches.
- Another disadvantage of organic mulch is that, because of its size, it is expensive to transport.
- Risk of Nitrogen-immobilisation: The decomposing bacteria increase swiftly in the soil when organic material is added. Like plants, they require nutrients, particularly nitrogen, for growth. The bacteria will pull nitrogen from the soil if the applied plant material is deficient in it. Since the nitrogen is temporarily bound in the bacteria during this process and released only after some time, it is known as nitrogen immobilization. The crop may experience starvation during this time as the bacteria and plants compete for nitrogen.
In conclusion, organic mulches are a great way to improve soil fertility and the environment. Mulches act like a blanket over the ground, keeping moisture in and preventing evaporation. They can also help prevent frost heaving by insulating the soil from extreme temperature changes.
They improve soil structure making it easier for plants to grow and thrive. They also increase organic matter in the soil which improves drainage and aeration.
Organic mulching also reduces weed growth by blocking sunlight from reaching them. This means that weeds are much less likely to grow through your organic mulch than if you had used plastic sheeting or other non-organic materials instead.
