In order to survive in various unfavorable habitats, plants have developed a series of adaptations. In the case of plants growing on light, sandy
and dry soils, the adaptation consists, among others, in on limiting transpiration.Plants solve this problem in various ways, for example by creating a wax coating on the surface of the leaves.It gives the plants a gray-blue tint.
Such adaptation can be found in many succulents which, apart from accumulating water, are often covered with a wax coating, e.g. many species of sedum, eshever, eonium, but also in other species, such as California poppy, coastal saplings or German iris.
Another solution to protect against excessive transpiration are the leaves covered with cutter, that is a thick "coat" of hairs, which also make the plants gray, and sometimes even white.Has it, among others Bieberstein's knotweed, woolly purgatory, cyrillic santolina, some yarns, mugwort, mullein and hellings.
Irrigation and root system development
Plants experience long periods of drought in the summer months. It often happens that, in order to ensure optimal development of plants, many of us decide to water them every day.Meanwhile, such frequent irrigation "impairs" plants, especially when we water them with a small dose of water, wetting only the surface layer of the soil.
The root system then develops shallow, which does not allow the plants to become independent.In order for plants to survive a drought on their own, they should have a strong and deep root system. Irrigation less frequent, every 3-4 days, but with more water - so that the soil is saturated at least several centimeters deep.
We can follow a similar principle when assessing whether the rainfall was sufficient - then we check the depth of soil moistening.A layer of only a few centimeters of wet substrate means the need for additional irrigation.
