Spinach

Thank you for getting back again on this. Deer would crop off most of the plant, rabbits would nibble like the one leaf you show, but probably would not stop there. I can think of no mammal that would do this damage. In reviewing your picture, the spinach in general looks fairly damage free, though way too close together. The featured leaf is out of focus, so it is hard to determine whether those “spots” are spots or rasped areas. Your location would be very good for there to be snails and slugs and when first hatched they are really tiny. Still there should be more damage to the other plants if you have an infestation. You may be right about the deer, but if so it took one bite and said UGH. Try putting some bloodmeal around the area and see what happens.
