Well, I let 3 window boxes wither. One was petunias, one marigolds,
and one Alyssum. The petunias were still green but brittle. The
marigolds had a couple decent blooms still, and were not quite
brittle. I cut off the tops of those two and gave them a moderate
watering. It's pretty windy here so I might give them more water this
evening. I know it might be a bit late in the season to get any more
blooms (I am in New York City) but was this the right course of
action?

PS: The Alyssum, which my wife never liked and would just as soon let
die, was still plugging along nicely. Lots of blooms that are
attracting the most amazing variety of blue, green and gold tiny flies.
