Primarily used for fertilizing potted plants, it is inserted into the soil; when watering, the nutrient solution flows through the fertilizer compartment, delivering both moisture and nutrients directly to the soil. It can be removed at any time when the plant has received sufficient nourishment or shows signs of over-fertilization.

Compact and convenient—a perfect companion for bonsai. Equipped with a lid to protect against wind and birds, it features evenly spaced holes that ensure uniform nutrient absorption, allowing water and nutrients to flow naturally into the soil.
