[NAFEX] Roundup under young apple trees

Any Roundup you get onto the trunk of the young tree will make it sick and 
possibly kill it.  Roundup is translocated throughout the tree.  After the 
tree is old and the bark is corky then it doesn't hurt anything.  That is 
why I quit using it around my young trees.  You can use a shield between the 
spray and the tree but then the shield gets wet and if it touches the tree 
then that is trouble too.
