Leaves Eaten Away

Question

I was wondering what is going on with my flowers. Every year this happens. I don’t see any kind of bug or worm on them. But my trumpet vine is being eaten away—especially the tiny new leaves. My marigold leaves are also disappearing. And my four-o-clocks were not very high when the leaves were disappearing. I am about to give up on flowers. I started spraying with soap and water. Will this help? Don’t like using poisons.
