When temperatures start to drop abruptly, some precautions should be taken protect the crops that fear gel mostor. In fact, if you are not lucky enough to have a heated greenhouse, you have to find alternative expedients. Here are the methods most used to repair vegetables from frost, according to their means and needs.
How to protect vegetables from frost: cassoni
To protect the young seedlings that will then be planted outdoors in spring but also to have salads, parsley, chives, etc. always ready for use during the winter, we can make caissons. At one time, these caissons were built by making the base in bricks and then placing old windows over it as a cover, which could be opened during the beautiful sunny days; in this way, air and sun could enter, thus preventing humidity from stagnating and favoring the establishment of fungal diseases. Today, these caissons are built in wood, plastic or any insulating material, capable of allowing light to filter, but with the possibility of being opened if necessary.
How to protect vegetables from frost: bells and caps
The covers of this type are indicated to cover the single plants; they can be tent, hood, bell or cube. They can be made of all kinds, from elegant glass bells to more improvised ones, such as old plastic bottles cut in two or transparent food trays, used as caps to be moved how and where you want. These protections are effective in protecting some vegetables from the cold of winter but also in helping the initial growth of newly transplanted crops in early spring. In any case, it is always advisable to facilitate ventilation during the hottest hours.
How to protect vegetables from frost: greenhouses and tunnels
Another economical and effective remedy for covering rows of seedlings is the tunnel, which can be easily assembled and opened. To achieve it is very simple; just choose a strip of soil no wider than 100-120 cm, where plants that need winter protection will be sown or transplanted. At that point, stick metal or plastic arches (there are already ready on the market) to the ground to be positioned at a distance of about 75-100 cm from each other. Finally, cover the tunnel with plastic sheet or agri-fabric and at the end fix pegs to stop the aforementioned sheet.

How to protect vegetables from frost: mulching
Mulching is another excellent remedy to protect the soil from frost and to prepare it optimally for spring sowing.
After working the soil, you can fertilize it with mature manure and then cover it with mulching material such as leaves, straw and other pruning or mowing residues. To improve the decomposition process of the mulching layer, you can also add rock flour, which is also an excellent fertilizer.
How to protect vegetables from frost: raised stalks
Raising the stalks, the strip of grassy land that delimits your garden, compared to the ground level can help avoid stagnation of water that is harmful to the roots of vegetables. 15-20 cm of rise is enough.
