Fertilizer baskets made of brown plastic are filled with organic fertilizer (e.g. Biogold Original), so they are protected from birds and cannot be washed off the surface by watering. The distance from the surface avoids possible moss burns. For an extra firm hold on the soil surface, these baskets with lids have a 5 cm long spike. 15-20 Biogold fertilizer chunks can be placed in it.
