Care and maintenance of the Rhododendron

The Rhododendron is a striking garden plant known for its exuberant flowering and lush leaves. It is a plant that, with the right care, can flourish for years and can transform any garden into a colourful paradise. To keep the Rhododendron in top condition, it is important to start with the right soil. This plant likes a slightly acidic soil with a pH value between 4.5 and 6. When planting, use special Rhododendron soil or mix peat into the existing soil. Also ensure a well-drained soil, because although the Rhododendron appreciates moist soil, it cannot tolerate boggy conditions.

A good location is essential. The Rhododendron thrives best in partial shade, where it is protected from the bright midday sun. Too much direct sunlight can scorch the leaves, while a spot that is too dark can reduce flowering. Water the plant regularly, especially during dry periods, but make sure that the soil does not become too wet. Preferably use rainwater, as tap water can contain too much lime, which affects the acidity of the soil.

Fertilization is another important part of care. Use a fertilizer specifically designed for acid-loving plants, such as Rhododendrons, and fertilize twice a year: once in early spring and again immediately after flowering. This ensures that the plant has enough nutrients to form new buds for the following season. Pruning is usually not necessary, but dead, damaged or weak branches can be removed after flowering. This helps the plant stay healthy and compact.

Another common question when caring for the Rhododendron is how to deal with yellow leaves. This can indicate an iron deficiency due to a too high pH value in the soil. In that case, it can help to add iron chelate to the soil. With these care tips, the Rhododendron can remain a colorful eye-catcher in the garden for years.
