Make sure your trees and shrubs are healthy and thriving all season long with Ross Root Feeder Fertilizer Refills for Trees & Shrubs. Use pre-measured fertilizer refills in your Ross Root Feeder to get the perfect balance of nutrients directly to plants’ roots – while you water at the same time! Simply connect a garden hose to the Root Feeder and insert the Ross Root Feeder Fertilizer Refill for Trees and Shrubs. Turn on water at spigot. Turn on water flow valve slightly until a stream of water flows out the tip of the feed tube. As water saturates soil, insert Ross Root Feeder at equal intervals in ring under outer branches (drip line) of the tree or shrub. Never at the trunk of the tree or base of the shrub. If soil is dry, continue root watering after Ross Trees & Shrubs Fertilizer Refills have dissolved. Tightly seal unused fertilizer in its plastic bag. Store in dry place. Ross pre-measured fertilizer refills make for fast, easy and mess-free fertilizing. Ross Root Feeder and Green-Again are registered trademarks of Easy Gardener, Inc.
