Susan from Frankfort Il writes
The Miracle-Gro Garden Feeder is made to be used with water-soluble plant foods, which would be a solid granule concentrate. According to the manufacturer, a 1 lb packet of plant food should make approximately 40 gallons of solution to cover 400 square feet, and it would dispense in 10-12 minutes. The feeder will dispense 4 gallons of solution per minute (about 15 Liters). If you are having trouble using the sprayer you purchased, please contact the retailer from whom you purchased it, or you can reach Scott's directly at 888-270-3714.
