what is being eaten? shape of the bites etc. could be rabbits leaf cutter bees, vine weevil and the next wave of slugs etc to invade your patch.

How can you be sure it isn't slugs or snails?

1st theres no slime. its the leaf thats getting eaten, shape is round holes.

They don't always leave slime and they do often eat holes out of the middle of leaves. I bet its either slugs or snails. Are there any signs of damage on the stems? Snails sometimes leave long trails of damage all up the stem. Try putting some bait down. If you still think its not that can you put n a photo?

thanks guys
