The fertilizer baskets made of brown plastic are put over organic fertilizer (e.g. Biogold Original) as protection against birds. The ends, which are about 1 cm long, are pressed into the surface of the soil to prevent them from slipping or falling off. They are available in two different sizes. Approx. 8 Biogold fertilizer chunks fit under the small baskets and approx. 20 chunks under the large ones.
