As the horticulturist for the Cockrell Butterfly Center conservatory, I get asked a plethora of gardening questions. The most frequently asked question (other than “How’s Lois?”) has got to be “How do you get your orchids to grow on trees?”
I explain to visitors that most orchids are epiphytic, which means that they grow on the trunk and branches of larger trees. To do this, they have developed ingenious ways to obtain water and nutrients without the need of soil. Not to be confused with parasites, epiphytes take nothing from the tree they attach themselves to. Notable examples include ferns, orchids and bromeliads, but the most familiar epiphyte to people here in the south is a wispy bromeliad by the name of Spanish moss.
There seems to be a common misconception that growing orchids is reserved for only the most experienced gardeners, but from my experience, this is not always the case. In fact, orchids seem to thrive on neglect; the most common cause of orchid death is over-watering.
To learn more tips and tricks for epiphyte growing, join me for the HMNS adult education class How to Grow Orchids, Bromeliads and Other “Air Plants” from 9 to 11 a.m. this Saturday the 24th in the Cockrell Butterfly Center. The class includes a behind-the-scenes tour of the Butterfly Center, followed by a hands-on class where attendees will learn how to propagate, divide, mount and fertilize their own epiphytes. And finally, everyone goes home with their very own orchid to start (or add to) their collection!
