Picking up where we left off: Sean and I spouted a crop of young seedlings on our windowsill and were about to transfer them to our rooftop, as part of our urban gardening experiment. In late April we figured that the chance of frost had passed, and that our little plantolescents were ready to make the transition and adjust to the conditions on the roof.
I had read that it's necessary to harden off your seedlings, gradually exposing them to more sunshine, wind, and elements before actually putting them in the ground. Unfortunately, my sources recommended an unrealistic schedule for a working stiff. I envisioned the call to my boss: "Sorry I can't come into work until 1:30 today, my plants need exactly four hours of direct sunlight..." So I made some limited attempts, dutifully carrying them up and down on weekend mornings, hoping that they'd get the message and toughen up.
