I have planted out some courgette's in a raised bed and now find that the leaves are slowely being eaten one at a time on each plant. I can't see any snail trails or sign of any other bugs. Can any one advise ? It also appears that my pepper plant is also being attacked. Not sure if it is the same thing but two lupins planted next to each other have been affected in a similar way , one is fine the other has been eaten away completely. As you can probably tell I am a complete novice.
