Application in steps
For existing plants
Fertilize your rhododendrons and other acid-loving plants in the spring, before the first bloom. Sprinkle the fertilizer on the soil and work it in well. If necessary, you can poke holes in the soil with a pointed object and sprinkle the fertilizer granules in them. Cover the holes again and water generously.
For new plantings
In spring, sprinkle 70 g/m². You can mix the granules with the soil before planting. When planting in autumn, the first fertilization is done before flowering the following year.
