Why do I always close the greenhouse in winter - because my sister did not close the door and was left without a greenhouse
Several years ago I bought a polycarbonate greenhouse that I have long dreamed of. My old greenhouse made of window frames is already completely rotten and leaky. Of course, a polycarbonate greenhouse is a moody hideout. But for those who live in a private house and always have the opportunity to open or close windows and doors, this is a chic option. I really like the fact that already in April I start the garden season, do the first crops and enjoy the first greens to the table.
But when the gardening season ends, I get very serious about preparing my hideout for next spring. In the fall, I bring in fresh humus, dig up the soil. I sow siderates. By the way, green manure mustard emerges in spring from those seeds that did not sprout in autumn, and I am happy to use young shoots for making salads. It really tastes better than the same lettuce.
Then I put the greenhouse in order, remove the weeds from the paths. My paths are covered with fresh sawdust, it's cheap, always dry and comfortable. In the future, I plan to pave them, but so far my hands have not reached it.
And when it snows, I close the doors and try not to enter it unnecessarily, especially in severe frosts, when polycarbonate is especially fragile. If you open and close the doors, the frame also experiences a certain amount of stress. It can be skewed, which will entail breaking the sheets.
My sister had an incident last year - she left the doors open so that the ground would freeze better. And one day, returning to the blizzard from work, I looked out the window, but the greenhouses did not. And only looking closer, she saw a frame with broken sheets on the other end of the garden! The shelter was simply lifted into the air by a strong gust of wind and blown away by several tens of meters. If the doors were closed, this would not have happened.
That is why I always close the doors, because the freezing of the soil does not depend on their condition. The temperature in the greenhouse and outside in winter, without the sun, is exactly the same. Polycarbonate, as you know, is not a frost protector.
Therefore, do not listen to bad advice, close the doors, and do not disturb the greenhouse until the first sunny days, when the temperature rises in it. It is then that you need to start putting snow on the ridges - the more, the better.
This snow will become a strategic moisture reserve, moist soil will warm up faster and better. Every day, starting in mid-March, I bring in whole piles of snow, but by the next day it is gone - it all melts.
These are the tips for a greenhouse for the winter. Maybe someone is doing better, I would like to know.
