How to Use Mulch in Garden?

Share on:

The health and beauty of the garden do matter to everyone. The health of a person indirectly depends on the health of his garden. As a matter of fact, the right kind of mulch applied at right time in the garden will help maintain and improve your garden. The use of mulch in the garden is a bit different because mulch is required to be replaced after each growing season.

By all means, mulch plays an important role in protecting your garden from different insects, weeds, and the environment if you use the right amount in your garden. Addressing the question “How to use mulch in your garden/garden bed”, In this blog, I have shared the answer to the above questions.

Before getting started, let me share brief info and facts that you should consider before laying mulch in the garden.

Things to Consider Before Laying Mulch in Garden

What Type of Mulch Do You Need for Your Garden?

The first thing to remember, mulch is a dead material that is applied to living things (grass, plants) to provide nutrients and protect the soil. So you have to intentionally select the right vegetable mulch for your garden first.

At the present time, there are many types of mulch available. Mulch is mainly divided into two categories;

  • Organic Mulch: It is the best and by far recommended type of mulch as it is organic in nature means it is totally natural and becomes the part of soil after a time duration and gives off its beneficial nutrients to plant roots and enrich your soil. It blocks weeds in your vegetable garden but is not totally efficient for weeds blockage.
  • Inorganic Mulch: Inorganic mulch is not naturally or you can say it is not originated from the plant source rather it has other elements in it. It is one of the best mulch to stop weeds due to its blocking and inorganic nature but it doesn’t give any value to the soil.

In the light of our discussion, Here I have listed some organic and inorganic mulches:

Grass Clippings as MulchOrganicGrass clipping can be used as mulch when you want to make your garden look greener, but grass clippings are widely used in lawns instead of gardens due to their rapid decomposing ability.
Bark as MulchOrganicWood barks (shredded or chipped) can also be used as mulch, especially in garden beds. They last longer than any other organic mulches and tend to be a suitable choice for people mulching around garden plants.
Straw and Hay as MulchOrganicStraw or hay mulch is the best mulch for a vegetable garden as it is easy to rake and handle, lasts longer, keeps lower-plant diseases away, facilitates beneficial insects, and makes paths in the garden less muddy so you can easily walk.
Pine Needles as MulchOrganicPine needles mulch is known to be used in the garden where evaporation and weed growth in the soil is the problem. But you have to be careful that always use fresh pine needles for mulching purposes and always use this mulch in less acidic soil otherwise this mulch is known for its acidic effects.
Shredded Leaves as MulchOrganicLeaves can be used as mulch. Shredded leaves are the best choices for woodland. Leaves would not be always a good choice for gardeners as they attract insects. But if you have not planted anything in the garden yet then you can spread leaves in the garden in the fall they will fertilize your soil in the winter.
Newspaper or Cardboard as MulchOrganicNewspapers are the best solution for the soil where you need moisture retention and weed control. 6-8 layers of newspaper spread on the soil will keep the weed away and also retain the moisture of the soil. All you need to do is just spread the newspapers on the soil, water it a bit, cover it with another mulch, and you are good to go.
Plastic or Landscape Fabric as MulchInorganicPlastic mulch or landscape fabrics are used in garden tunnels, on slopy lands, and around foundation plantings. They are a great choice in the sense that they don’t need any care, they are cheap and excellent weed supressant. However, one major drawback is that they increase soil temperature during summer and also, and they are detrimental to soil decomposition. However, making holes in the plastic and replacing it before decomposition can prevent your soil and garden loss.
Gravel or Stone as MulchInorganicThis mulch is good for Mediterranean herb gardens and rain gardens as it helps in proper drainage and lets soil heat escape for better plant growth.

So from the above table, you get an idea about what mulches you can use for your garden. If there is a garden bed, vegetable garden, or flower garden, you now have a better idea of which mulch you should select. Even in this regard always go with the best mulch for your garden based on its purpose of use.

After selecting the right type of mulch, now comes the problem of how much you need it.

Amount of Mulch You Need

Estimate how much mulch you’ll need to use in your garden.  There’s nothing more aggravating than selecting the mulch you want and realizing that you don’t have enough of it. Usually, a mulch bag is 1m3 which can cover up to 3-inch (7.5 cm) thickness for an area of 12m2. You can use this estimate to calculate the mulch you need for any type of garden or area you have.

When to Use Mulch in Garden

It is another important factor you should know before mulching your garden. Know when is the best time to mulch your garden. It is usually spring and also it depends on a number of factors like soil type, mulch type, climate, and plants you are growing in your garden.

Miscellaneous Ideas Before Mulching in Garden

  • Mulch shouldn’t be too thick or too thin. Mulch should be 2 to 3 inches thick when applied. Anything that is thicker than this could harbor pests, but it is also inefficient and unnecessarily expensive.
  • By the same token, the thickness of biodegradable mulches should be between at least 5cm (2 inches) and at most 7.5cm (3 inches) in order to be effective.
  • Mulches should be applied over moist soil after weeds have been removed, but before the soil becomes frozen.
  • To emphasize, planting through mulch sheets is an effective method of establishing new beds.
  • Avoid mulch volcano. A mulch volcano occurs when a massive amount of mulch is placed around the stems of garden plants. Not only is this an inefficient use of a resource, but it is also detrimental to the garden’s health.
  • Always maintain a mulch layer about 2″ away from the base of vegetable plants. Keep the 2-inch rule in mind: 2″ deep and 2″ apart. In either scenario, you can go up to 4″, but stay within that range for both depth and distance.

Tools Required to Use Mulch in Garden

Shovel: If you’ve had mulch scoops delivered to your home, you’ll need a pitchfork or shovel to put your mulch into a wheelbarrow, so you can move it around your garden.

Wheelbarrows: Wheelbarrows are great for moving mulch to different parts of your garden quickly and easily.

Steel garden rake: to break up and spread mulch in the garden, a steel rake is required.

2. Remove the Weeds

Many times people ask “how to mulch a garden to prevent weeds?” Here is a simple most important step to answer this query. Before spreading mulch, make sure to remove all the weeds from the beds. It is necessary for the proper functioning of mulch. Point often overlooked use gloves for this purpose. You can also use a weed killer like Roundup Concentrate Plus to kill weeds.

3. Transport the Mulch

On the negative side, straw bales are huge, heavy, and difficult to transport throughout the garden. If you intend to use straw as mulch, attempt to find a partner who will assist you in transporting the bales to the gardening area. The use of a cart or wheelbarrow to transport the bales is quite convenient and economical. Straw is also unsightly, and the thick stalks can be painful to poke with. When breaking down the bales, it’s a good idea to wear gloves.  For eyes, wear some eye protection to protect yourself from the dust.

4. Spread the Mulch

Once the string or wire has been removed, the straw will normally soften and self-divide into “flakes” of various sizes. As an illustration, these are compacted areas of the bale that are considerably easier to handle and spread than the loose sections. Hold a flake of straw in one hand while using the other to pull handfuls of stalks free and scatter them around the bed with your other hand. The more mulch you spread on top of each other, the more effective this mulch will be at suppressing undesired weeds.

5. Maintain Optimum Mulch Thickness

Maintaining optimum mulching thickness is what will be helping your vegetable garden to get better results.

A 2″ to 4″ layer is ideal. Maintain a mulch depth of no more than 4″ and no less than 2″ and you will see a noticeable change in the health of your vegetables and garden. Additionally, you will notice a decrease in the amount of supplemental water required.
