    Do Orchids Grow in Hawaii? And How! SYNOPSIS This is an historical sketch of the Saga of Orchids in Hawaii. The sequence of events from the incidental introduction of species by the Agriculturists for the Sugar Industry; to their efforts in propagation and culture, hybridizing and germination; to the development of personal nurseries to commercial ranges; and ultimately to the creation of a viable orchid industry, re­ cognized world wide; to the natural formation of orchid societies staging of orchid shows; and finally to the introduction of a system of orchid judging , should bring interesting reading to orchidists, amateur and professional alike. In fact, this could serve as a reference syllabus to keep. DO ORCHIDS GROW IM HAWAII? AMD HOW i Compiled and Edited by Dr. T. David Woo and Wallace K.

  • World Orchid Conference Trust Report
    Attachments to Houston Minutes Spring 2009: World Orchid Conference Trust Report The Proceedings of the 19th World Orchid Conference (WOC) held in Miami during January 2008, is in the final stage of publication. I will have a hand-bound copy in Houston that I would be happy to show to anyone who is interested. The others should be available within the next month and will be shipped out shortly thereafter. The organizers hope to be able to complete whatever tasks are still pending and close the corporation this summer. Details for the 20th WOC change with some regularity due to the world’s economic climate. Kiat Tan is the head of the Organizing Committee for the Conference in Singapore and he is working closely with the government, which is underwriting the main part of the Conference. Currently the 20th WOC is scheduled for November 2011, with the Show and Conference to be held in the Marina Bay Sands Integrated Resort. The Sands is currently under construction but should be complete and open by late 2010. It is adjacent to the new Gardens by the Bay which is also under construction. Hopefully some of the facilities of the Gardens will be available during the WOC. Work on the 21st WOC in Pretoria, South Africa, continues. There is a show scheduled for March 2010, which the Organizers intend to use as a rehearsal for the WOC. If anyone has any questions, please see me in Houston or e-mail me at [email protected].

  • Orchid Disease Control Part 2 - Bacterial and Fungal Infections by Sue Bottom, [email protected]
    St. Augustine Orchid Society www.staugorchidsociety.org Orchid Disease Control Part 2 - Bacterial and Fungal Infections by Sue Bottom, [email protected] If you’ve grown orchids for a while, you have noticed different blemishes on them and wondered what causes the problems. Some genera of orchids just seem prone to certain diseases, like Thai crud on the leaves of vandas, and orchids seem to come under disease pressure during certain times of the year, like botrytis flower blighting during cool weather. You learn, sometimes by the School of Hard Knocks, how to recognize disease symptoms in the types of orchids you grow. Then you have to figure out how to eliminate the disease from your growing area and prevent it from recurring in the future. Healthy Plants are More Resistant to Disease. With orchid diseases, your primary directive is to prevent disease from occurring. First and foremost, you strive to fine tune your culture to grow the healthiest orchids because vigorously growing plants are more capable of resisting disease via their natural defense mechanisms. Cultural controls go a long way in preventing conditions that favor disease: proper watering to minimize excess leaf wetness, buoyant air movement and adequate plant spacing to keep spores from settling on plant surfaces, well drained potting mixes that are refreshed if organic matter degrades and strict attention to sanitation. Cutting tools and pots should be sterilized between uses, benches and under bench spaces should be kept free of weeds and debris as well as disinfected regularly, decaying flowers and vegetation should be removed promptly to sealed containers and any severely diseased plant tissue should be cut from the plant to eliminate the pathogen from the growing area.

  • In Orchid Culture Where Plants Are Grown for Years in the Same Pot, Weed, Control Can Be a Serious Problem
    -5- WEED CONTROL IN ORCHIDS Charles A. Conover Assistant Ornamental Horticulturist In orchid culture where plants are grown for years in the same pot, weed, control can be a serious problem. There are some growers who would, dispute this statement, however, I would, know that these growers were lucky enough to escape having Oxalis corniculata or Dicliptera vahliana in their greenhouses. Oxalis and Dicliptera are troublesome pests because they are rhizomatous per ennials and their seed, pods snap open and. propel seeds for several feet. Other weeds causing serious problems for the orchid grower include algae, mosses, and. ferns. Many other weed, species can be a problem, but these are the most trouble some. Hand, weeding is, and. probably will continue to be, one of the main methods of weed, control. However, with weeds that produce rhizomes, hand weeding is entirely unsatisfactory since parts of the rhizomes may be left in the pot to sprout again. Hand weeding may also result in removal of sections of the medium and can cause injury to roots. In addition, hand, weeding cannot control seed, germination and in a short time pots may be reinfested with a large number of weed, species. Algae and. mosses are particularly hard to remove from pots and. can be quite unsightly. Thick growth of moss and algae may also restrict aeration of the medium and. can cause a reduction in growth. In recent years a large number of selective herbicides have been developed for control of weeds in various crops. A selective herbicide is a material that will selectively kill weeds without causing injury to the crop being grown.
