Fito Orchid Plant Food Drip Feeder provides automatic feeding for your orchids, perfect for when you're on holiday. This ready-to-use feeder delivers a slow-release food solution for 15 days. It can also be used on other acid-loving plants such as azaleas, rhododendrons, cyclamen, and camellias. To use, water the plant thoroughly before inserting the vial into the soil. Cut off the top of the vial and place the nozzle at a slight angle, facing away from the plant. Variations in soil type and density can cause differences in the flow rate, but each vial is designed to last approximately 15 days, ensuring your plant receives sufficient nutrients.
