I have a thick planting of morning glories growing at least 7 feet high on two connected tripods. At the very top something devoured only the entire top layer leaving nothing disturbed on the sides or bottom. This is inside a fence that deer couldn't jump and further inside an electric fence to discourage groundhogs and racoons. This is also in a raised bed around 2 feet off the ground. Nothing is left but the stems. This all happened while I was away this afternoon for a few hours. Are there any birds or small rodents that have an appetite for morning glory leaves? Rosepatch
