Fito Drop by Drop Feed for Citrus Plants is a new way of feeding all types of pot grown citrus plants. It is ready to use and ideally balanced to supply the right amount of feed daily. Each vial provides a gradual and balanced release of nutritive elements sufficient to feed a plant for an average of 15 days, encouraging more abundant fruiting. The formula is specifically designed for all types of citrus plants such as lemon, orange, grapefruit, tangerine and bergamot. Regular use reinforces the defences of the plant against the stress of indoor life. Easy to use, simply snip off the top of the vial and insert into the soil at a slight angle away from the plant. Can be used all year round. This pack contains 5 x 32ml vials.
