The rhododendron and its characteristics -
The rhododendron is a beautiful but quite demanding plant. Its complicated name comes from the Greek and literally means "rosewood."
The genus Rhododendron, or rhododendron, includes several hundred species of shrubs. Outside of Europe, they are mainly found in Asia and North America. For three centuries, scientists have tried to group individual plants, often difficult to distinguish. For simplicity, gardeners divide the genus Rhododendron into: evergreen and non-evergreen rhododendrons, with leaves that fall for the winter.
Where to locate rhododendrons
The rhododendron, like other shrubs, likes semi-shady locations that are well protected from the wind. This plant adapts to air saturated with water vapor and humid and cloudy weather. They feel best in moderate temperatures without sudden fluctuations.
Regarding the substrate, rhododendron grows best in permeable soils, with humus, fertile and acidic (pH 4-5).
In large gardens, rhododendrons should be arranged in groups. Plants are best selected in terms of size, habit, and flower color. The individual elements look beautiful as lonely. Miniature varieties can be grown in containers and rock gardens. These shrubs should be planted under large trees, because they can tolerate even a lot of shade.
We must plant the rhododendron in holes with a diameter and depth of about 1 m. It is important to put a drainage layer at the bottom, which will protect the roots of the plant from waterlogging. Cover the drain with a prepared soil mix suitable for rhododendron. Then we cover it with a layer of bark. In this way we will avoid excessive evaporation of the water, we will protect the roots and acidify the soil. It is better to repeat this treatment every year.
From spring to the end of summer, it is worth supporting rhododendrons with special fertilizers. However, be careful not to disturb the soil too deeply, as this can damage the roots.
In the case of shrubs that lose their color and look weak, acidifying preparations of the soil are recommended.
These shrubs do not require pruning, but it is worth regularly removing discolored inflorescences and dead and damaged twigs.
Systematic watering is also extremely important, especially after frost and in summer.
Although some varieties tolerate drought quite well, in general they should not be allowed to dry out.
