It has suddenly become colder outside again, and you are standing near the greenhouse and thinking whether to ventilate it or not? Let’s find the answer to this question together.
A greenhouse in a garden is a must. Under this “protection” your plantings grow more actively and begin to bear fruit faster than outside the greenhouse. And for air circulation in the building, a door and sometimes even vents are provided. But do they always need to be opened?
Sometimes the weather even in summer presents not very pleasant surprises in the form of sharp fluctuations in temperature. Gardeners care more about outdoor plants at this time. Caring for greenhouse crops undeservedly fades into the background, as they are more protected from such weather surprises. But greenhouse “sissies” also need attention. And one of the main questions of a cold summer is whether to open a greenhouse in nasty weather?
One of the main fears of the farmer is connected precisely with the fact that the plants will freeze and the family will be left without a crop. Therefore, many gardeners tend to thoroughly “wrap” them during temperature changes, even if these plants are in a greenhouse.
At first glance, this position seems to be correct. Plants are warm, greenhouse protects them from wind and low temperatures and they have their own microclimate inside. However, there is another side to the issue, which novice gardeners often do not think about. This is an accumulation of condensate inside a greenhouse or greenhouse. Settling on the walls, it subsequently returns down in the form of drops and at the same time gets not only into the ground, but also onto plants. Water containers left inside the greenhouse also create additional moisture. And if the plantings are not ventilated, then excess moisture on the leaves can cause the development of spots and rot of greenhouse plants. And nightshade crops are also at risk of late blight.
How to protect plants from excess moisture in nasty weather
Therefore, do not be afraid to ventilate the greenhouse even on cloudy and not too warm days. Get your plants air circulated for at least a couple of hours a day. And it is best to open the door or vents during the day, when the air warms up as much as possible. If, after that, your plants began to mope (there were signs of chlorosis, and the leaves look a little drooping), spill them with one of the growth stimulants according to the instructions.
Please remember that if you have installed automatic window openers, they will not open in cold weather!
If for some reason you did not ventilate the greenhouse and signs of disease appeared on the leaves of the plants, treat the plantings with one of the suitable fungicidal preparations.
Remember that weather “extremes” in gardening (and the greenhouse is no exception) are always dangerous. Whether it is cloudy weather with rain and wind, or, conversely, the scorching sun.
