You will likely have better response in either the Ask a Question forum or the regional forum closest to your area or even in the Perennial forum. The forums get a lot more traffic and people 'watching' them, whereas asking a question in the database entry will only be seen by folks researching that particular plant, or by folks (like me) who scroll down the list of recent comments added to the database. It would also be helpful if you could post a photo of the damage. I am not familiar with Mayapple, so I'm no help to your problem. Good luck and happy gardening.
