Tree experts recommend watering and fertilizing below the soil’s surface, where most of the active tree roots grow. The Ross® Root Feeder’s deep feeding system is specially designed to do exactly that. Simply connect a garden hose to the Root Feeder and insert the feed tube into the soil around the dripline of a tree. Water flows through a chamber filled with fertilizer, through a feed tube right to the tree’s roots. Perfect for drought weather, there is no runoff and wasted water, just healthy, beautiful trees all season.
