PLANTING AND TRANSPLANTING : Page 91

Protection After Transplanting. Large trees when trans-planted must be amply protected against evaporation during the hotsummer months. This protection is given to the tree in two ways.First, a mulch consisting of straw, litter, or leaves is applied to a depthof six to eight inches, over an area eight to ten feet in diameter, im-mediately around the base of the tree. Second, the trunk is wrappedwith burlap or bagging to prevent excessive drying out. Many newlytransplanted trees are injured by the hot rays of the sun throughlack of this protection which prevents a drying out of the bark andcambium tissue on the exposed trunk of the tree. This drying outoften results in injury to large trees (as shown in Plate VII, Page 75)to such an extent that the bark cracks, dries up, and becomes loosenedfrom the trunk of the tree thus exposing the inner wood immediately under the bark. It is quite as necessary to provide suitable mulchduring the winter months of the next season after the transplanting,as to provide one in the summer months. In a newly transplantedtree a fine root growth is developed near to the surface of the ground,and this root growth is easily injured by any excessive freezing andthawing which may occur during a severe winter.
