Kc from Cincinnati, Ohio writes

Will Killzall harm hemlock trees in a garden being treated for weeds?

Answer:

Killzall Weed and Grass Killer - 41% Glyphosate will not kill the tree when applied on less windy days and not applied directly to the trees, especially the foliage. Avoid direct contact with desirable plants.
