I have never been in the habit of throw snow in the greenhouse. At the cottage, I am only in the season and rarely finds time on the site is a lot of snow. But for the overall development, I decided to look into the matter and even conduct your own experiment. Fortunately, with the advent of the car to visit the cottage has become much easier.
Why throw the snow in the greenhouse
Snow in greenhouse throws to spring the soil soaked with moisture and "woke up" after a long freezing. Such a process allows to prepare the ground for early planting.
The important point is that the land is impregnated with melt water, which according to many is much more useful, and the well water. Therefore, to compare the process with the spring watering properly.
When the throw in a greenhouse snow
Snow in greenhouse throws in the late winter or early spring. This is done so that in extreme cold land remained open and freely froze. This eliminates the majority of pests that overwinter in the upper soil layer.
Is there any point in this procedure?
To be a theorist, I decided to test the effectiveness of the method in your garden. To this end, I came to the country at the end of February and distribute about 30 cm of snow in the greenhouse layer thickness., And then closed the windows and doors. The procedure was not as simple as it might seem at first glance. Given that I worked a bayonet spade, I do not have to spend a little time and effort.
What was the result
March that year was sunny, so by April all the snow has melted and the soil has had time to dry before the appearance of fine dust. Before planting, the land still had to be watered.
For myself, I made this conclusion. If you spend the whole winter in a country house near the garden, then throw the snow in the greenhouse can be. If you spend time and summer resident in the area only in the season, then the procedure does not make much sense.
