Protect the roots of your plants from the cold with mulch or mulch

Mulch, mulch or mulch is one of the maintenance tasks that we always recommend because it is very interesting .

During the autumn and winter the roots of the plants of the orchards and gardens suffer the consequences of the low temperatures characteristic during these seasons of the year.

The frost and cold can damage plant roots because they are very vulnerable to sudden changes in temperature , especially younger plants. But luckily, to prevent having this problem we can implement some strategies to protect the roots from the cold and one of them is mulch or mulching.

We also advise you which organic seeds to use , the best planters, growing boxes and tables for your garden and essential books to learn everything about organic gardening .

What is mulch?

Mulch, mulch or mulch is a widely used technique in permaculture and agroecology because it is quite multifaceted and offers good results.

This technique basically consists of placing organic or inorganic materials on the land that surrounds the plants, such as:

Gravel, straw, dry leaves, sawdust, pinnace, cotton or wool textiles, hay, pieces of bark, grass clippings, algae or cardboard.

Keep in mind that if you put a mulch with larger pieces it will take longer to decompose and will require less maintenance than if we put a mulch with smaller or finer pieces that takes little time to decompose.

This cover that is placed on the ground will maintain a more constant temperature and will protect the roots of the plants when temperatures drop and there is frost.

In addition to protecting the roots from the cold, mulching provides other benefits:

Boosts the growth of beneficial microorganisms.

Avoid the emergence of spontaneous or uncultivated plants (the so-called weeds ).

Provides organic matter to the substrate

It improves soil structure

Maintains a constant and adequate temperature of the soil

Helps keep the soil moist.

Savings in irrigation water

Protects the soil from the sun and wind erosion

The biological activity of the microorganisms that live in the earth is improved.

Once you have chosen the type of padding, keep in mind some basic guidelines:

  • Prior to its placement, aerate the soil, leave it loose and eliminate the unwanted plants that have come out in the area where you are going to put the mulching.
  • It is preferable to put the padding once the floor has a certain degree of humidity and when it is not cold .
  • If you choose organic materials, such as pruning debris, leaves, etc. they do not need to be cut into very small pieces.
  • Do not place the mulch close to the stem of the plant , leave a radius of about 10 to 15 cm. This way we prevent fungi and other diseases from appearing.
  • The mulch must be put, at least, on the entire surface that the plant occupies
  • Usually a layer of padding between 3 and 5 cm thick is installed if you opt for more compact and humid materials and a layer between 4 and 7 cm thick if you choose those that are drier and lighter . It is important to take into account the thickness of the mulch because if it is too thick it does not allow air circulation and excess heat can be produced that damages the roots.
  • You should also bear in mind that for soils with a tendency to compact, materials such as hay, straw or sawdust are usually more beneficial.
  • When you use materials such as grass or leaves, which tend to decompose quickly, the mulch requires more maintenance because it must be renewed more frequently.
  • Leave a small hole to help the water seep into the substrate.
  • Once the mulch is placed, it is watered
