Shut up! We were in the car and old leadfoot took off from the stop light just as I started to finish post. Anyway!....There's a couple of plant books that I dearly love. One is: What A Plant Knows by Daniel Chamovitz, Ph.D. He's a biologist that writes about how plants actually sense danger and alert the other plants, etc... It makes me think before I yank a puny plant out of the beds, ....that maybe I should give it a little more time to recoup.
He also writes that seedlings seem to be able to communicate feelings of danger, etc. to the other plants. They seem to be able to know up from down, etc. I just think that having some plants growing in the same pot will be company for them and maybe, just maybe...they will all come up and be perfect little specimens in spring!
