While reading the Sun Sentinel today I came across this article in the 'lifestyle' section (http://www.sun-sentinel.com/features/home/fl-hgjuneau-garden-column-082811-20110828,0,7535261.column) and it confirms exactly what I thought....hence why I have been relocating my orchids from their confining little clay pots to the expansive area of the trees in our landscape. With just a little observation to your environment, you can gain tremendous insight on being a better gardener. Listen and learn from Mother Nature and you will do fine. :)
Happy Gardening my friends!
