I'm so sorry, I really feel for you- I've had squirrels dig up and destroy most of my Pelargonium collection as well.
And steal from my bird feeders.
I keep telling my mom that I'm getting an air-soft gun.
Such a shame, after all that. I hope that orchid bounces back!
I knocked a developing leaf off of the only lead on my L. anceps division a few weeks ago- within a few days, two of the dormant eyes had taken off and started growing to take it's place. Hopefully yours reacts the same way!
I've heard cayenne pepper paste/spray can deter squirrels, and if not- they make pellets you can spread around that are supposed to repel them.
