You want to install a greenhouse in your garden and you realize that it is not that simple. Once you have chosen the location for it, you need to prepare the ground. Here are some tips for obtaining a suitable floor taking into account different elements.
How to limit soil salinization in a greenhouse?
In a greenhouse the atmosphere is confined and you use fertilizers. As a result, the salinity of the soil is higher than it would be outdoors where it rains. So that the salt level does not increase in too large proportions, it is necessary to water in an efficient way. By performing water rinses like the rain does outside, you limit the increase in salt in the soil.
Excessive salinity disrupts the development of plants and roots. If salt is essential, it should be present in sufficient quantity, but not in excess. We must not try to make it disappear, but just to regulate it. A soil with very high salinity can be recognized by the thin white layer that covers it. These are the salt crystals that form on the surface.
You have a solution which is also very effective, it consists in draining the soil sufficiently. The goal is that the roots of the plants do not permanently stagnate in the water. This is the danger when you have to water often and in quantity.
When you add fertilizer, select a natural product that is especially low in sodium. Fertilizers that are marketed for the purpose of fertilizing vegetables, herbs or fruits are perfect. Some are also able to act for three months while being perfectly ecological. It should be incorporated superficially when you plant or sow.

How to prepare your soil?
When you set up your greenhouse, pay close attention to the acidity level as you do elsewhere in your vegetable garden. If the pH value is less than 7, your soil is too acidic. It is therefore necessary to restore a normal acidity rate with maërl.
It is also necessary to loosen the soil and aerate it and put organic fertilizers in the top layer of the earth.
Water regularly in the morning or in the evening preferably.
Ventilate the greenhouse regularly.
Soil replacement
Soil runs out faster in a greenhouse than outdoors, simply because the growing period is longer. The soil should be replaced once a year, at least for the first 10 centimeters. It is in fact this layer that preserves salts, disease germs, crop residues and weeds. If you replace it every year, you avoid diseases, salinization, weeds. The soil will be more fertile and suitable for cultivation.
With these few tips, your greenhouse is perfect for growing and getting the best results. It takes a bit of work, but mostly it’s also a question of regular maintenance.
