1. I have noticed lot of holes coming up in leaves for the weeping cherry tree since 2 years now and don't see any visible insects around it. I sprayed a generic tree care couple of weeks back before the leaves sprouted but it has not made difference. Please can somebody help suggest a remedy.

2 on the another ornamental plant, i see the leaves and flowers are infested with some kind of rust disease. It is dying, can somebody suggest how to protect this beautiful shrub.

Thanks,
GP
