Larry,
I like your "label" idea. As long as it can't crack, I can't see how a squirrel would be able to pull it out of the ground.
Geez, am I embarassed.
I didn't remember I had deleted the blog " What's planted where" on DGarden. I remember now I deleted it because so much was moved around during the past 2 years, the info really no longer was accurate. Anyway, I'm glad you were interested in the photography tips. You're right, it isn't easy to get a decent photo of a 10 foot area. If I was crazy enough though, I might just lie down in front of the bed and try taking photos from that position looking straight on. Problem is, I would have a very hard time getting UP from that position.
