Q.Rose Leaves Yellow
My rose plant leaves have turned yellow. What is causing this, and how can I stop it?
If it is the lower leaves turning yellow, it is a natural thing. The new upper foliage sometimes shades or shadows the lower leaves. Since the bush does not need them anymore they turn yellow and fall off. If it is all over the rosebush, it could be too much water which makes the soils muddy and allows little oxygen flow. Sort of drowns the rosebush. If it is the over water problem, just hold off on any further watering until things dry out a bit. Then give the rosebush some cheleated iron fertilizer and water lightly. If the rosebush is in a container, make sure the saucer at the bottom of the container does not hold water in it longer than about 1/2 hour after watering. This too can cause root zone problems leading to yellowing foliage and death of the rosebush.
