All the mint on one side of the garden is messed up. On the other side of the garden, the mint is healthy.

The roses appear to have blackspot.Pick off all the diseased leaves and treat the rest of the plant.Don't water anything overhead.I'm not sure what the problem is on the mint.

It looks like insect damage to me. In New Jersey we have these bugs that start out real small and suck the juices from all my herbs. They then grow up and can fly. Perhaps you have something like that. They are real crafty and it's hard to see them because they move real quickly. Try to check real early in the morning. Good luck
