Instead of repotting trees and shrubs into larger containers each year, simply replace the upper layer of compost with fresh new compost.

Float on top to form upper layer.

The extract alters the 'microenviron-ment' surrounding the layer of skin stem cells between the upper layer of the skin, the epidermis, and the lower layer, the dermis.
