Holes are appearing in the middle. Just on a couple of leaves so far - what I noticed last night anyway. My m-i-l says some type of worm.
Wonder if it's cut worms...but they usually eat from the edge of the leaf in.
Hey, they are fun to get rid of...just take you wife out in the garden with a couple of flashlights and pick the worms off (they come out at night). Once you get all the worms picked off and killed...you can make out!
