Description Use these durable brown plastic cups to protect your bonsai fertilizer cakes from birds and other animals when your trees are displayed outdoors. The cups also help prevent fertilizer cake material from breaking down into the soil and clogging it, allowing only the nutrients to flow through as intended. Each cup measures 1½ inches in diameter and is reusable season after season. A simple, effective solution for maintaining clean and efficient fertilizing practices in your bonsai care routine.
