I brush my seedlings, not regularly, just as I am passinng through, and I am forever moving the trays about so they do get wiggled and jiggled, and all the time, I am chattering away to them. This is the saddo saddest of sad things tho....when I go to the greenhouse and see brandnew seedlings appearing in a once baron seed tray, I always welcome them to the world and congratulate them on breaking out! I shall retire now as the men with white coats have come a-knocking at the door........ ;)
