When we look around the countryside, we can notice, that older homes are usually in sheltered valleys, tucked away from frosty, winter wind. Currently, houses are also built on higher elevated areas, from which there is a wonderful view of the surrounding area. Problems with such a location appear then, when the owners of the house want to establish a beautiful garden. Strong winds turn out to be the main obstacle. In such a situation, you can indeed plant plants, which will protect against the wind, but what then with a breathtaking view?
Gardens in cities are also exposed to the adverse effects of the wind. Concrete city spaces absorb and accumulate solar energy, therefore they have a higher temperature than in rural areas. Air chimneys are being built around larger buildings. Plants grown on balconies have to cope with strong sunlight, temperature fluctuations and gusty winds.
When frosts are announced, gardeners growing crops in certain regions have more to worry about. Gardens close to the sea tend to be less prone to frost than these, which are located inland and in higher altitudes. There are places, in which, additionally, pools of cold are formed and frosty air accumulates. When planning a garden, it is therefore worth noting even the smallest details related to weather phenomena typical for a given region. Such statistics will help us choose the right plants and locate the most secluded places in the garden. If, as a result of such an analysis, it turns out, that the microclimate of our garden is more like a meadow, Mediterranean slope, a forest or an area ideal for fragrant flowers, let's accept it and try to make the best of the local conditions, instead of fighting them.
Cold pools are places, in which the frosty air flowing from higher-lying areas is stopped. They often form in valleys, and on a micro scale under barriers, which can be dense hedges, fences and walls. Freezing air, accumulating in the depressions, it destroys the plants grown there. Spadek temperatury powoduje powstawanie różnych osadów atmosferycznych. One of the most spectacular is frost, which we can observe, when the air is humid and the water vapor it contains turns into ice crystals.
When the temperature at the ground drops below freezing, with a daily average greater than 0 ° C, frosts appear. If ground frosts persist too long, evergreen plants are dying, because they are unable to extract water from the soil. Usually their condition improves with the thaw, unless they are plants with a very shallow and cold-sensitive root system.
