What are webinars? Webinars are an internet conference where you can hear the speaker and view his presentation, ask questions, and hear interactions from other members of the audience. You can join either on your computer or by phone. You can join from anywhere, via your Mac, PC or even your mobile device. Audio is included, so attendees can phone in or use VoIP (Voice over Internet Protocol). You will need a microphone for your computer to use VoIP. If you cannot make the actual presentation, there will be a link on the website where you can view the webinar at your convenience.

New Digital Membership Level


Our membership has welcomed the digital edition of ORCHIDS magazine. Now AOS is pleased to announce our new digital-only membership level. Today there are many options for having editorial content delivered to our home or office. While for some, the feel of a paper magazine in-hand cannot be replaced, the convenience of an archive of magazines on a device that fits in a pocket cannot be denied. For those who want both, our regular membership continues to fill that need. For those people on the go who want to be able to catch up on the latest ORCHIDS as time permits, our new digital-only membership is perfect. The digital edition includes robust tools that allow notation, bookmarks, different viewing options and pdf download. You can search a single issue or an entire volume. Perfect for students and researchers! Add an Orchids Plus® subscription to your membership and you have access to a wealth of orchid information - anytime, anywhere, on any device. Join or renew today, or click here to learn more about AOS membership benefits!

This year the American Orchid Society Fall Members' Meeting will be held at the Sheraton Orlando North in Orlando, Florida in conjunction with the 16th International Slipper Orchid Symposium. The dates are October 29 through November 2, 2014. The event promises to be an orchid extravaganza featuring world class lectures. Lecture topics offer something for everyone, from Phals to Paphs. Registrants will also be able to be able to attend meetings of several orchid specialty groups. The orchid show will include AOS judging and vendors from around the world.

The Fall Members Meeting are a great time for meeting old friends and making new ones. The event is an excellent way to expand your network of orchid friends. As you will see in the agenda, the schedule is packed with fun events like the preview party, AOS auction and banquet. If you have never been to an AOS Members' Meeting, take the plunge. You won't regret it!

We are preparing text and images for our fifth annual magazine supplement. What started as a way to publish an article that was too big for a regular issue of ORCHIDS (Phil Spence’s comprehensive look at the Latouria section of Dendrobium) has become an eagerly anticipated bonus issue of the year. A separate publication gives us the opportunity to present a monograph to our members each year without compromising the general interest of the monthly issues. We continually strive to improve the quality of the supplement giving AOS members a valuable addition to their orchid libraries.

We have an excellent subject* for the 2014 edition that we will announce here in due course. Once again we appeal to our members for a small (or large) donation to underwrite the expense of the project. Your donation serves as a vote of confidence that you want us to continue producing an annual supplement. Please select "Annual Magazine Supplement" as donation type. Thank you.

Coconut Chips

I am having good luck growing my orchids in coconut chips. Should I be using a balanced (with a 1-1-1 ratio) fertilizer or a high-nitrogen fertilizer (3-1-1 ratio) as for fir bark?   — J. Jameson
