Q.my garden is experiencing brown to yellow spots with holes
The plants vary from tomato to lettuce and also my roses, but only the leaves. Anything that has green leaves is with holes and brown to yellow color. Most of them are eaten too. There is just the stem of the plant. I would like to know what it has and how to treat it.

It sounds like you have a fungus and the weakened plants are also attracting pests. Treat the plants with both a fungicide and a pesticide. Neem oil is a good choice as it is both. It is also organic and safe for people and pets so can be used on food crops.
