Rick Lockwood to Speak at September Meeting
What Orchids Eat
In that never ending quest for culture perfection, growers look for clues in both the environmental or ecological realm, and the agriculture sciences realm. The predominant information obtained from eco./enviro. sources is generally limited to physical parameters like temperature, light, and humidity. Chemical data from ecological sources is often fragmentary or at scale not applicable to orchid growers. The information obtained from the agri-science community dominates our feeding application regimes, but is primarily based on high turnover food crop and ornamental cultivars. My quest has found evidence that indicates that the chemical environment of in situ orchids is considerably different from the cultivation standards for the food crop and ornamental plants that many of us have modeled our feeding programs after. While still integrating basic agri-science principles, I have also found that reconfiguring the application of macronutrients (N P K Ca & Mg) to more eco relevant concentrations can dramatically improve orchid culture, especially for sensitive species.
Rick Lockwood Bio
From the age of 5, Rick has been figuring out how to culture oddball organisms, and after graduating from UC Irvine became a herpetologist and aquarist for the Oklahoma City zoo. After leaving the zoo biz in 1995, Rick became an environmental toxicologist for Ramboll Environ, where he is a managing scientist for the aquatic toxicology division of the Nashville, Tennessee office. He has focused on salt (in particular potassium) toxicity issues since 2005. His wife, Robin, rekindled his love of orchids in 2001, and has since been passionately pursuing the study of species orchid culture, breeding, and conservation. He is an active and past office holder of the Orchid Society of Middle Tennessee and a major contributor on the SlipperTalk orchid forum. Slipper orchids are his favorite, but it took almost 10 years before he “got it right” to the point where he is achieving AOS awards with his favorite flowers. Besides slippers Rick also keeps an extensive collection of species Bulbophyllums and Phalaenopsis.
