First choose rhododendron site correctly, then plant
When you replant or implement a rhododendron, the question arises: where is the optimal location? Which floor does the evergreen ornamental shrub prefer? What Rhododendron love and what is not clearly summarized here ...
Rhododendron wish list location and soil
Originally originated. Rhododendron from Far Eastern highlands. There they thrive at high humidity on thin humus layers. They love light and shade under deep-rooted trees like oak, pine and fir. Light foliage or canopy protects against direct midday sun and acts as the ideal backdrop for the voluminous rhododendron flowers.
Due to the wide range of locations from light to shade, rhododendrons feel comfortable almost everywhere.
Nevertheless, you should always observe the following optimum soil and site conditions:
The optimal rhododendron location in native gardens
The cultivated in our gardens. Rhododendron species love wind-protected, partially shaded locations with high humidity. Climatically they prefer cool, humid summers and short periods of cold with little frost in winter.
Ideal shade dispensers for rhododendron: deep-rooted, light-leafed or coniferous trees or the north wall of a building. Too much shade restricts the flowering and the growth becomes loose and sparse.
Basically, the higher the humidity, the sooner the rhododendron will tolerate a sunny location and vice versa.
Alpine, hardy wild species from locations above the tree line can tolerate full sun, such as:
The ideal soil condition
Rhododendrons prefer humus rich, acidic, evenly moist soil and cool soils. The optimum pH of the soil is between 4.0 and 5.0.
Exception: The INKARHO rhododendron varieties are especially suitable for alkaline and calcareous soils.
Waterlogging and soil compaction lead to nitrogen and oxygen deficiency. The result: Harmful organisms, such as Phytophthora spread and the rhododendron dies.
Excessive pH above 6.0 limits the availability of iron. The growth of the plant decreases significantly. Growth depressions and chlorosis on the leaves are the result.
Countermeasures: A soil improvement to correct the pH value and fertilization with trace element preparations lead to the regeneration of the plant.
Eyes open at the rhododendron purchase
When buying a rhododendron, look for a compact growth, healthy, dark green leaves and many flower buds. Healthy, vigorous plants acclimatize and grow better at the new location in your garden.
Hands off rhododendron with brown or yellow leaves, these are indications of a root disease or nutrient deficiency.
Tips & Tricks
