Tree experts agree watering and fertilizing below the soil's surface is best. This is where most of your tree's active roots grow. With a deep feeding system, the Ross® root feeder is specially designed. Connect a garden hose to the root feeder, then insert the tube into the soil around your trees' drip line. Water flows through chamber filled with fertilizer and goes straight through a tube into the trees' roots. With no run-off or wasted water, the root feeder is perfect for drought weather.
