Problem With Victoria Plum Tree

Question

Our plum tree is in a large pot and in a sheltered position. We give it plenty of water and it is producing plenty of fruit about 1. 5 times thumbnail size, but we have recently noticed that some of the leaves have developed brown streaks. Is this a problem and if so what can we do about it ?

If the streaking is nearest the leaf veins, it might be a virus. I would suggest taking a sample to your local agricultural extension office for identification and recommendations for treatment.
