Jonathan Robbins: Asking the Right Questions to be Your Own Orchid Expert

Jonathan first became interested in orchids in 1994 during a horticultural internship at the Marie Selby Botanical Gardens in Sarasota, Florida. The internship turned into a full-time job and he worked there for several years, learning about all sorts of tropical epiphytes. Jonathan went on to move around the country over the years but always had a greenhouse full of orchids. He has grown them in hot, wet Southern Florida, the cold, wet, Pacific Northwest, and the hot, dry, California Central Valley. This has given him experience with the challenges of growing in widely varied conditions.

He went on to buy Calwest Tropical Supply (Now Flori-Culture: Orchid & Specialty Growing Supplies) in 2014 and relocated it to Carmichael, California. By now he has added a small specialty nursery as well as the supplies they have always carried. He will discuss many of the major issues facing orchid growers, including: Light, Watering and water quality, Potting media, Container choice, Fertilizers & Pests & Diseases. Also vetting the over-abundance of information in the internet age.

He will talk you through ways to look at your plants and with a little observation and research, figure out for yourself the best ways to grow your plants according to your individual conditions. Jonathan will also give some strategies to tell which advice to listen to and which might be better ignored.

He is accepting pre-orders for supplies to bring to the meeting. Please email jon@calwesttropical.com to submit your orders.
