Plant Healthcare/Deep Root Feeding
Deep Root Feeding contributes to the growth and development of private trees. Compare tree fertilizing with humans taking multi-vitamins. People can survive without them, but vitamins provide essential nutrients needed for a healthy life. Likewise, fertilizing helps trees defend against insects and diseases as well as heal wounds caused by pruning. The end result is much healthier trees.
Granular slow release fertilizer applied on the surface of the soil drains through the soil and is absorbed by the tree roots. This method also fertilizes the grass and sometimes limits the amount that actually reaches the tree. It can also burn the grass.
