OSMO Hydrangea & Rhodo is a natural fertilizer with a gentle and long-lasting action. This balanced formula has been specially developed for hydrangeas, but is also suitable for other plants that like acid soils, such as heather, azalea, rhododendron, skimmia, etc. The potassium supplement guarantees intense flowering. The organic matter in this fertilizer is transformed by the organisms living in the soil. This improves the soil structure.
