1 June 2018 Page 1 AFFILIATED WITH AMERICAN ORCHID SOCIETY AND FLAMINGO GARDENS BOGO Two Speakers for the Price of One! Sandi Jones, Is it a Climber or a Crawler? & Bill Hodnett, Mounting in Coconuts By Sandi Block-Brezner, 1st VP Programming Sandy Jones of Broward Orchid Supply Is it a Climber or a Crawler?? Sandi Jones, owner of Broward Orchid Supply, will be our speaker on Monday night, June 11 th. Sandi is giving a new talk on growth patterns of orchids. We ve all experienced orchids that continue to grow outside their pot some go down the pot and others go up! She will show us how you determine if your orchid plant is a climber or a crawler and if it should be mounted or re-potted! And if you should be mounting it, do you put it on a vertical mount, or a horizontal mount? Or maybe it belongs in a basket or on a tree? And if you have to divide your plant, which part do you use... and is the remaining part viable to be used in another pot or on another mount? These and many more questions will be covered in her presentation! At one time, Sandi had worked as a paralegal and was also an orchid hobbyist grower. She was (and still is) a member of Ft. Lauderdale Orchid Society (FLOS). In June of 2006, Sandi started Broward Orchid Supply (BOS) because she found that there was no place in Broward County for the home hobbyist like herself to buy orchid supplies! By December 2006, she organized the first Bonnet House Orchid Show with 12 vendors and herself. Gradually Sandi grew her business by giving lectures at local orchid societies and doing demonstrations and classes at various venues. Most of her lectures are about the basics of orchid growing and deal with potting, fertilizing, pests, and diseases. At her home in Hollywood (2411 Garfield Street), she has set up a storefront and a lovely covered patio area where she continues to give orchid classes. You can also find her at many of the orchid shows from Palm Beach County down to Miami-Dade. She is a big supporter of FGOS and always donates orchid supplies so we can make the raffle baskets for our show! She has also begun to donate many of her orchid plants or divisions to the Flamingo Gardens Orchidteers! Continued on page 2

She will not be bringing everything she has, however; if there is something special that you want, be sure to call her at or her at browardorchidsupply@comcast.net and order it. If you pre-order, she will bring it to the meeting and you can pay for it then.. No delivery charge! You can also go on her website, to see her price list. Sandi s storefront hours do vary, so be sure to check the website and call ahead if you ever plan to visit! Bill Hodnett, an Orchid Master, Mounting in Coconuts Bill Hodnett, one of our very own favorite people, will also be presenting at our meeting. I know you have seen Bill s beautiful Vandas, large Dendrobiums, and gorgeous Cattleyas that he grows in coconut husks! Whenever a Cattleya outgrows its coconut husk, Bill just adds another husk and it keeps on going! I have asked Bill to show us how he first attaches an orchid to the husk, and what he does to prepare the orchid and the husk and keep it growing! Bill said he got the orchid bug and started growing orchids after attending the 1998 South Florida Orchid Society Show at the University of Miami. His favorite orchid is the large flower Cattleya. Bill has been known to make the ladies in his church lovely Cattleya corsages for their birthday and he has even cut the blooms off of some of the plants he brings in to Member s Choice and gives them out to our ladies! Bill has also become one of the Flamingo Garden s Orchidteers! Besides donating his time, he has also donated a battery operated fertilizing & watering tank and orchid plants to the gardens that he willingly gets up on a ladder to mount!! Bill other big love is Photography. He is a gifted photographer and has won 1 st place in the Photo Challenge both years since we ve held it!! Bill has about 1,000 orchids in his collection, though he s starting to reduce it! He said he started using coconuts because they are cheap and he is lazy! Coconuts are free, no pots, no potting mix, and repotting is easy! Come to the meeting and see how!!

3 Page 3 Did you have a good time at the Redlands International Orchid Show? Not the best weather for an outdoor show but I think everyone still had a great time. This was the last show of the season. You have to wait for Fall when they begin all over again. The rainy Season has arrived! That means the dreaded Black Rot makes an appearance. Be sure to check on your orchids every day. Take action immediately! Sandi Block-Brezner has shared an article from the AOS website about caring for your orchids in the rainy season. You may want to save the article for future reference. Have you thought about being on the Board of Directors? If you think you would like to join the board or work on a committee let us know. The board meetings are open to anyone. Our By Laws are posted on the website and there are job descriptions for you to review. We will be working on the Slate of Officers for next year in June and July. The Photography Challenge will be coming up in November. Time to be taking photos of your orchids or orchids anywhere you see them. The best way for a chance to win is to enter. Give it a shot! The next three months we will be meeting in the Education Room due to the Borworski Glass Exhibit. Come check out these amazing pieces made of glass and metal. The Gardens will be open several evenings so you can see the exhibit glowing in the moon light, well, hopefully. This is the first time this exhibit has been in the United States. The Board formed a committee to evaluate the guidelines for showing your orchids. They are working on ideas so members who do not have large collections or who are just getting started will bring in their plants to show. This is because we want you all to participate and feel good about your blooming plants. More on that soon. See you at the June meeting! Jan

4 Page 4 Is There a Fungus Among Us? (reprinted from the American Orchid Society Website) Black rot has decimated this tray of Cattleya seedlings overnight. We grow our orchids in an open shade house, (or yard) which means that they get whatever Mother Nature gives them. A wet summer is following what was a wetterthan-usual winter. That in itself was enough to deal with because as you know, orchids generally follow a seasonal growth cycle. Even though most of the ones we all grow are from the tropics, they still prefer a cool, dry winter. They also do best with ample water during the growing season. As you might expect, our wet summer has made plant growth explode. Though the plants are growing tremendously, every morning I go out to check to see if any fungal infections have begun. Our prolonged rain prevents plants from drying out, sometimes for a full week or more. Wet foliage provides a perfect environment for fungus dispersal through splashing water. Based on past experience we have come to expect an outbreak of black rot under these types of wet, humid conditions. Pythium ultimum (and/or Phytophthora cactorum) is ruthless and can destroy a collection of cattleyas in short order and those plants you do manage to save will be set back for years. Although cattleyas are its favorite host in our collection, it does not discriminate and will infect other genera, especially soft-leaved types such as Grammatophyllum, Stanhopea, Oncidium, etc., Black rot is our biggest nemesis but wet conditions can bring out other nasty fungi too. Black rot on Guarianthe bowringiana. It should be obvious that healthy plants are less susceptible to fungal infection just as healthy people are less likely to get sick. We have come full circle back to the topic of balance in orchid culture. While we want to grow our orchids as vigorously as Continue on page 5 Fungus

5 Page 5 Continued from page 4 Fungus possible during the summer, we want to avoid vulnerable soft growth and do whatever we can to prevent rot problems. Soft growth can result from low light levels, too much nitrogen fertilizer without increasing other culture variables and other stress-related causes and is more susceptible to disease. Here are some suggestions for summertime orchid culture. 1. Strive to maintain a balanced culture regime. If you find you are watering plants more often in summer try to gradually provide more light and make sure you fertilize regularly. 2. Provide adequate air movement. The importance of ventilation in orchid culture cannot be overstated. Moving air promotes rapid drying of watered plants. Roots that stay constantly wet will deteriorate more quickly than those that are allowed to dry between waterings. Water standing on leaves provides a place for fungus spores to incubate, especially Pythium species. Moving air also helps keep leaf temperatures down. This is especially important in summer. 3. Make sure your growing area is clean and free from debris. Decomposing leaves and other plant material under benches make a perfect breeding ground for fungus and bacteria. 4. Excessive algae growth can keep surrounding areas overly damp and provide a fertile environment for fungi. We spray benches and the wooden structural parts of the shade house with an algaecide such as Physan or RD-20 in late spring and at least once again midway through the summer. As long as you don't subscribe to the "more is better" theory and mix strictly to label recommendations, plants can be sprayed as well. Too strong solutions can burn soft-leaved orchids. Be advised that if you rely on live moss culture for Pleurothallids and other pure-water orchids, these chemicals can kill moss. 5. If you are not afraid to use agricultural chemicals*, prophylactic spraying of plants with a broad-spectrum fungicide (such as Captan 50WP, Dithane M-45, Cleary's 3336, etc.) once or twice a season can provide protection against many fungal problems Should you be unfortunate enough to experience Black Rot or other fungal problems there are accepted treatment protocols. If a leaf is compromised to the point where it will be lost anyway, it is best to remove it. This is especially true with Pythium. Cut the infected part off with sterile shears or a new single-edge razor blade. Cut at least a Continued on page 6 Fungus

If you can still see a dark discoloration of tissue such as in the photo at left, cut deeper until you reach healthy, green plant tissue. Using a small amount of one of the fungicides mentioned above, mix with water to make a paste the consistency of heavy cream. Using a disposable cotton swab coat the cut edge of the healthy tissue. This would also be a good time to consider spraying the affected plant as well as nearby plants with a targeted fungicide to prevent further infection (Aliette WP, Subdue 2E, Truban 30WP). Keep the plant isolated and dry until the infection has abated. If a leaf has only minor fungal spotting it can be left on the plant but should be sprayed top and bottom with an appropriate fungicide. Some hobbyists also like to dust with cinnamon. Note: When using any agricultural chemical always make sure the product is listed for the plants you intend to use it on. Follow label directions exactly. Wear protective clothing. Do not spray around children or pets. Wash thoroughly after spraying. Greg Allikas June 2012 S i l e n t A u c t i o n Want to sell some of your orchids or other plant related items?

8 Page 8 Tolumnia Program Recap by Sandi Block-Brezner Last month our speaker was Daryl Venables, of Telezulaplants.com. Though we had a nice turn out, it was a pretty wet and rainy night so I thought I d give a brief recap of his program in case anyone is interested in giving these small, interesting orchids a try! I learned a few new things too! There are two types of Tolumnias those with long rhizomes (he calls them ramblers!) and those with short rhizomes. The ramblers, or those with long rhizomes, Daryl says you should mount on anything from twigs to a little bit bigger size mount. He likes cedar though warns not to use treated cedar. Tolumnias like rough surfaces. He suggests getting scraps from lumber mills or wherever lumber is cut. You can also use cork or wire one to an S-hook. They must be fastened securely. He uses pantyhose cheap ones! He cuts off the toes & tops, rolls each leg separately, like a donut, cuts all around, unwraps, and has long thin strips to use. It s a great idea that can be used with any orchid you mount! A Tolumnia with a short rhizome, he prefers to pot in net pots so they get air at the roots. The media he prefers: Charcoal (small pieces)-he boils for 30 minutes, and then lets it dry for 24 hrs. Coir or coconut husks, though he warns to be careful; it can have sea water in it. He soaks it for a week changing the water daily! Tolumnias need morning sun only, not midday full sun! Most Important!! Keep Dry in Winter! They only get morning dew in the Caribbean in the wintertime. In winter, he waters in his greenhouse only one minute (Like dew in the Caribbean!) There is one greenhouse he does very early in the morning for 10 minutes but it is bone dry by midday or within 2 hrs. (I assume these are on mounts!) Pots must be watered very, very early and be dry by midday. Very important Tolumnias need air at their roots!! In nature Tolumnias grow where there is wind! He uses fans 24/7. They also need high humidity. Once they finish blooming Don t cut the flower spike until it s completely dry! It can still produce side branches and flowers! Fertilizer Daryl uses MSU formula (Michigan State Formula) for Tap water which is low in phosphorus because our water has enough phosphorus all ready. (The three numbers represent the content of primary nutrients in the fertilizer formulation: nitrogen, phosphorus and potassium.) He is experimenting with MSU K-lite version (12-1-1). Pests and Problems watch for brown rot aka Erwinia! Actually it s a bacteria and won t respond to a fungicide; you will need a bactericide (let s hope you don t need it!) Daryl uses Physan. (½ tsp/gal for normal root plants; ¼ tsp/gal for thin root plants of any kind!) Continued on page 8

9 Page 9 Tolumnia Program Recap continued from page 7 BTW Although Federal regulations say you should not, many growers substitute the cheap and readily available pool algaecide which contain the same active ingredient. Per Martin Motes in his book Florida Orchid Growing, Home Depot sells a brand called ''Pool Time'' which could be purchased legally to disinfect walks and pathways at the rate of 1 to 2 tsps. per gallon and would certainly do no harm at that rate, if it came into contact with the orchids no more frequently than every 7-10 days." Physan/Pool Time are products that you can spray on wet orchids during rainy season at the above rate to help prevent fungus. Some also say there is some effectiveness on scale crawlers and other delicate insects too. Physan/Pool Time also seems to mix well with most insecticides and fertilizers, functioning as a surfactant. I am careful however, about using them on Dendrobiums, though others say you can. Perhaps not on species, (or test one first!) Happy Growing!
