• Easy to use: inject the fertilizer directly into the bonsai soil and water the plants so the fertilizer dissolves. • Design with small holes: the mesh baskets have multiple holes at the bottom and sides, allowing the fertilizer to slowly penetrate the soil without burning the roots. • Pack of 100 units: sufficient quantity to control the dosage of the fertilizer. • Effective protection: the caps protect the fertilizer from being eaten by birds, insects, wind, or other disturbances, maintaining the beauty of the plants and mosses. • Versatility: suitable for potted plants, indoor plants, patio plants, hanging baskets, pots, hanging orchids, and outdoor gardens.
