Do it nowFertilize roses for the final time early this month, then quit for the season. It's time for roses to slow their growth and start preparing for winter dormancy. CONNIE NELSON

Hot. Humid. Wet. No, it has not been a great summer for lots of garden plants. My begonias look scorched. My chard looks scared and confused. But there's one group of plants that has been very, very happy with the recent weather.

My tropicals, the big-leaf exotics that I stick in a few pots on my deck, are doing great this summer. The canna are happily putting up new shoots and bursting into bright mimosa-colored blooms. The elephant ears are living up to their name -- bigger than I've ever seen them -- with huge leathery leaves longer than my forearm. New shoots and leaves sprout constantly, and the biggest leaves flap gently in the breeze like a herd of black elephants.
