Question
I have a climbing bush behind my garage in full sun.  It does well for the first growing of new buds in the spring.  It flowers beautiful in the spring.  The problem is after the flowers die off all the leaves fall off aqnd the bush looks really sick.  What causes the leaves to fall off?

Answer
Can you tell me what colour the leaves are when they fall off? If they are yellow it could be a lack of iron in the soil. The other could be spider mites which you can see if you look under the leaves and there will be tiny pale spiders underneath the leaves. The rose could be a once bloomer too. Thanks for your help.
