Show DRESSING FOR TREE WOUNDS Waterglass Found Most Satisfactory by Expert at Ohio Experiment Experi-ment Station. Waterglass was found the must satisfactory sat-isfactory dressing for tree wounds in tests made by W. J. Young of the Ohio experiment station. A dressing made for pruning wounds should slick well to the cut surface of the wood, exclude air and moisture, h.nd protect the tree from attacks of fungi which cause rotting of the wood. White lead paint, grafting wax, gas tar, and many other substances as well as water-glass, water-glass, which Is commonly used for preserving eegs, were tested. Waterglass readily unites with the sap of the tree and forms a successful coating over fresh wounds. Pure lead paint, though especially useful In poisoning the rot-producing fungi, does not stick well unless applied after the cut surface becomes dry. Waterglass, It was explained, prevents pre-vents the flow of sap anil appears to preserve the wood from decay. After treatment the cut soon becomes dry and a coat of lwid paint may he applied ap-plied over the waterglass for additional addition-al protection if desired. The water glass may be applied as purchased, or If too thick to spread well, a little water may he added. |
