Something has essentially topped 5 or 6 of my pepper plants by nearly half in my raised bed. It has gone primarily after my shorter plants and left the taller ones alone so far. It has also taken branches off of several others. Yesterday there was no apparent damage. I walked out there this morning and noticed damage to a couple of them. Went to work and when I got home the rest of the damage was done. Anyone have some ideas as to what this might be? There are birds in the bed sometimes picking out worms but they have been doing that since plantout 3 weeks ago with no damage to plants. Some kind of pest maybe? Seems like a lot in one day though. Rabbits or squirrels? Any help is appreciated.
