DESC: Patented feeder and ready-to-use refill bottle system takes the guesswork out of feeding: No mixing, no measuring, no mess! No more guessing when the plant food is gone when the bottle empties, feeding is done. Automatically applies plant food at an even rate no worry of over- or under-feeding. Feeder easily switches between feeding and water-only options. Three spray patterns (shower, jet and flat). Simply attach the feeder to the garden hose, insert the refill bottle into the feeder and then spray plants and flowers. One Liqua Feed refill bottle will feed 400 sq. ft. in approximately 15 minutes. For best results, use every 7-14 days. Ideal for all types of flowers, vegetables, trees, shrubs and lawns. Kit includes feeder and 2 plant food refill bottles.
