Question
I have about 12 rose bushes that look health to me but all the leaves on them are falling off.  The leaves are still green just a couple of black spots on a few but it's all the green leaves that are falling off.  I can't find any bugs but I can't figure out why the green leaves are falling off.  The branches look bare with beautiful blooms.  What do I need to do or get to put on them?

Answer
As I don't know where you garden I will have to take a guess on what is the reason for the leaves falling off. Weather does play a part in putting a rose under stress. If the weather turns hot quickly, the rose will often drop its leaves because it is under stress. Any thing that effect a roses ability to survive will cause a rose to drop it's leaves to live as it doesn't have to support them. The other possibility is that although you are watering the rose the water somehow just isn't getting down deep enough and this will make the rose drop all it's leaves. You can check by digging along side of the rose to see how deep the water went down. The third reason is that a spray was used, such as an insecticide or fungal one, and the rose is re-acting to it.
