Mine look the same. Lots of slugs this year plus I did find some striped Colorado Potato Beetles, which I promptly squished.

Welcome to the what's eating my plants club.
I am going out hunting tonight, I suggest you do the same to try and see what is eating the plants.
Good Luck!!

Tiny slugs. Saw them on the leaves just before dark. Plucked off as many as I could find.

Naturally this brings up a few questions...

Where do they hang out during the day?
How did they get there in the first place?
How do I keep them away?
What about the leaves that have been destroyed?

1) In the dark.
2) Moisture and food.
3) Beer Traps, poison, diatomaceous earth, . Also, no mulch -- which I don't garden without it so I live with the fact that I might have some slug issues.
4)If they're otherwise healthy, leave them be-- the plant can use all the photosynthesizing surface area it can muster after having been munched on.

Good Luck.

I had a slug problem. Sluggo fixed it quickly!

Iron phosphate pellets, sluggo is one brand name. In your case, I suspect they are hiding under the pots during the day, but basically they live everywhere in little pockets of moist plant decay. Very helpful in nature, a bit destructive when they get into gardens in large numbers.
