But what is mulching? Mulching consists in creating a protection of the soil all around the plants that it is intended to cultivate, in order to prevent harmful removal of moisture from the soil. Moreover, the practice of mulching prevents the proliferation of weeds and their attack on plants and vegetables. This function is of particular importance since weeds and weeds, in case of penetration into the soil, would compete with vegetables by subtracting the precious nutrition they need to live and grow in the best way. Moreover, mulching, in case of heavy rainfall, prevents the washing away of nutrients contained in the soil - in particular, of mineral salts such as nitric nitrogen.
Moreover, it is very useful in some cases to make mulch using organic covering materials, so that during the cultivation period this organic substance slowly releases the nutrients that help the vegetables throughout the vegetative cycle.
When not using a synthetic material, it is good to use organic material such as straw, dry leaves, leftover grass clippings, compost and the like; everything will be laid on the ground forming a layer at least twenty centimeters high so that it can carry out its mandate profitably. In some cases it is possible to mulch with plastic materials such as sheets in polyethylene or non-woven fabric, both of strictly black color. Sometimes, when available, it is possible to replace plastic sheets with black, biodegradable corn leaves in the earth.
MILLING AND SUMMER
In addition to performing a contrasting action against weed proliferation, as we have said, mulching is very much needed to maintain a degree of freshness and humidity in the surface and in the substrate of the cultivated soil, avoiding that during the hot season - especially if dry and dry - it dries excessively losing the moisture accumulated during the winter season. When cultivating types of plants that require a high degree of humidity, or in any case not too low, mulching is the ideal solution to avoid dangerous dispersion of humidity.
MACHINING AND WINTER
The mulching technique is a real panacea even during the winter season and in the coldest periods of the year. In fact, by covering the ground with a layer of organic or synthetic material (remember, of strictly black color), those plants that are not suitable for cultivation in cold climates are sheltered from dangerous frosts. Keeping the roots sheltered from the cold will prevent them from withering to death, with fatal consequences for the rest of the crop.
MAIN TECHNIQUES FOR MILLING
In the field of do-it-yourself gardens, the mulching technique is used above all in the cultivation of plants that remain for a prolonged time in the ground, thus undergoing greater exposure: in the vegetable gardens that host the growth of strawberries or varieties of salad it is possible to see whole areas subject to mulching.
There is a substantial difference between mulching in vegetable crops and mulching used in green areas such as gardens.
In the first case, we need to spend a little more energy and a few more grams of fatigue: first of all we need to clean the soil of all weeds and weeds; afterwards we proceed with the covering with the black synthetic sheet (or with non-woven fabric) as long as it is strong and able to withstand weathering. Subsequently, it is necessary to make a series of holes on the mulch sheet. In these holes the plants to be cultivated will be housed, well separated from each other and safe from attack by weeds.
This is a kind of mulch that, although rarely, is also used to protect evergreens or flower beds. In this case, however, after the covering, everything will be hidden by using bark or lapillus to spread abundantly.
For those who wish, there are some biodegradable mulching sheets on the market - as mentioned above. Usually in sheets of corn paper, these sheets - once their mandate has been fulfilled - can be dug together with the ground and reabsorbed within a year or a year and a half.
Mulching: SOME MATERIALS FOR MILLING
As we know, besides the synthetic mulch sheets, it is also possible to use some alternative materials: where aesthetics must have the upper hand, then we will use more beautiful materials to see, such as lapillus, pine bark or dry leaves.
In all cases, mulching with organic substances is recommended because - especially if the mulch is long-lasting - it will nourish the substrate with precious nutrients that will prove very useful during a possible vegetative cycle in the cultivation of vegetables. Keeping the soil rich in humus is always moist and varied, it is the first step to obtaining excellent quality crops and growths.
