Hi there, I live in Southern Ontario, near Niagara Falls. I've transplanted 3 ft Hicks Yews along my driveway to start a hedge. I've spread a think layer of pine mulch. The conditions are full sun. A couple of the plants are starting to change color. Not the tips of branches, but the whole plant - it is getting lighter in colour. I beleive it will turn brown in a few days. Would this be the result of too much water or too little? Thanks!
