I have a crop of romaine lettuce, and something ate my lettuce from the inside out, what is it?
Hi, Well sadly there's no way of me knowing what happened without seeing the location and the leftover crop, my instinct is that you have a rodent of some sort at work. Insects don't usually work in this manner, plus you'd see some indication of the insects on the plant. If the leaves are just gone, then my first guess would be rabbit, squirrel, voles or some other critter. Sorry I can't be more helpful, but I have very little information to go on.
