Thanks, Melissa
I'm not hanging onto much hope here, but I'm SO disappointed that out of 14 seedlings, it was the variegated one that was taken.
Maybe the slight difference in color attracted the bird's attention, thinking it was diseased or filled with bugs or something.
Remember the commercial, "I could've had a V8 (knock)". That's the way I felt when I saw the word Rootone in your post. I'm out of town for a couple days, hope it's not too late when I get back. Not just for root stimulation, but maybe more important, for fungus prevention.
Right now they are in open air but under glass to keep dry, in bright indirect (no direct) sunlight. Wish I'd dusted the pieces with Rootone before I left!
