Mulch against weeds and cold: materials to be used to counter the growth of weeds and protect the root system from frost damage.

Theremulchis a very useful technique forweed controland to protect plants from the cold within certain limits. Mulching has a large number of advantages, we have summarized them on the dedicated page:mulch, advantages.

On this page we will make a summary of thematerialsto use for themulchperformed for weed control and to protect the root system from cold and frost.

Mulching materials

There is a lot of talk about mulching materials, here is a selection that will be useful both in the garden and for growing in pots. Mulching, in fact, is a very useful technique also for potted plants: it brings the same benefits and allows you to add an extra aesthetic touch! Here are what materials to use for themulch against weeds and cold.

Mulch with peat, dry leaves and straw

By spreading peat and river sand (in equal parts) on the surface of the pots, you can protect the plants from the cold and limit the growth of weeds. The only concern is to compact the materials very well.

Periodically, you can incorporate the mixture into the soil below and renew it. For best results, add straw or dry leaves on top of the peat and river sand layer.

Mulch with vegetable fiber panels

Between new generation mulching materials plant fiber panels are included. Being a novelty, they are found in agricultural consortia and in the most well-stocked garden centers.

These are panels made of kenaf fiber, a fiber hibiscus used as a textile material for over 2,000 years. The kenaf fiber for mulching is sold in the form of a round or rectangular panel, to be cut out according to the needs of your cultivar.

As well as kenaf fiber panels, jute panels (or jute bags to be recycled), coir panels and other plant materials can also be used.

Pine bark and pine cone shells for mulching

Pine cone shells are as effective as bark and wood chips, however they are not very common. Indeed, pine cone shells can have a higher yield than the bark because they are larger and therefore more resistant to the wind.

Pine cone shells and bark can be considered natural herbicides against weeds. Thesemulching materialsthey manage to control weed growth in two ways.

The bark is obtained from the maritime pines, it acts against weeds both for covering, therefore not letting the light through, and for the presence of resin. The pine cone is equally effective, indeed, thanks to its larger size it is better distributed on the ground.

Volcanic stone for mulching

Not all the mulching materials seen so far are completely inert, therefore, for better or for worse, some materials change the composition of the soil.

Volcanic lapilli is an inert mulching material. A natural material that does not alter the composition of the soil in any way. It has a good yield and considerable resistance to degradation, retains moisture and counteracts the growth of weeds.

Biodegradable plastic or bioplastic for mulching

Unlike the materials seen up to now, which must be renewed even after years, biodegradable plastic has a short duration.

Biodegradable plastic for mulching lasts approximately as long as a crop cycle. In particular, bioplastic mulch sheets made from corn starch have a very short duration, in fact they begin to tear after 3-4 months.

The sheets are able to protect the crops of weeds but are not suitable for the garden or for longer-lasting pot cultivation.

    Sorry for interfering ... I have a similar situation. You can discuss.
