NEXT MEETING IN DADE COUNTY
Tuesday, October 28, 7:30 p.m. at Fairchild Tropical Garden, 10901 Old Cutler Road.
Rufino Orsorio, author of the popular book, A Gardener's Guide to Florida's Native Plants, will show slides of South Florida wildflowers and discuss their cultivation. Rufino is an avid gardener and amateur botanist who specializes in the cultivation of Florida native plants, especially the small shrubs and wildflowers. Originally from Chicago, where he grew woodland and prairie plants, he has lived in Palm Beach County for 15 years and is a member of the Florida Native Plant Society.
Thanks in advance to refreshment donors: Gwladys Scott, Sandra Cleland (drinks and ice); Chris Migliaccio, Patty Harris, George Childs (snacks). Additional to the refreshments and raffle plants are always appreciated.
November 25 meeting: Dr. Laura Ogden, FIU Dept of Sociology and Anthropology – the role of local residents in transforming the Everglades from an "unknown" landscape to one known to science. See her book (co-authored with Glen Simmons) Gladesman: Gator Hunters, Moonshiners and Skiffers for a sneak preview.

FIGHT LOBATE LAC SCALE WITH OIL SPRAY
Lobate lac scale is a new scourge and extremely potent threat to South Florida plants. This exotic insect pest was first seen here in 1999 and last year spread into many private and public gardens and natural areas in Dade and Broward Counties. You will instantly recognize this small, dark scale with four lobes. Heavy infestations form a solid crust of insects.
Native and non-native plants have been affected and some, especially the native wax myrtles, are dead or in decline. Some species, however, apparently can tolerate the scale, which is good news. The search has begun for potential biological control agents, but it is at least 2 years away from release if one is found.
Most "native plant people" want to avoid using dangerous chemicals. Many are reporting success with oil sprays to kill adults and to stop the spread of the scale by its "crawlers. Ultrafine, Superfine and Sunspray horticultural oils, available in the pesticide section of garden centers, are appropriate for our hot weather. (Do not use volck oil, which burns plants here.) Organocide has also been used successfully. The best time to spray is when plants are dry, wind is calm and the temperature has dropped. Spraying in late afternoon may increase effectiveness and lessen the likelihood of plant damage. Be careful with an oil spray during hot weather to avoid plant damage. Read the label to see what maximum temperature is listed. With any oil spray, first test on a few leaves and wait a couple days to check for phototoxicity. Thoroughly cover twigs (the favorite spot of the scale) and repeat the treatment weekly for a month. After that, reapply when new scales are found. The old dead scales may persist for a long time and be confused with live scales.
If you prefer to use a homemade spray, Adrian Hunsburger, Urban Horticulture Agent/Entomologist at the University of Florida Miami-Dade Extension, recommends: 1-2 Tablespoons of vegetable oil per gallon of distilled (or reverse osmosis) water -- 50 cents/gal at the grocery store. (Or use 1-2 Tbsp. vegetable oil to 1 gal water, 1 Tbsp. white vinegar to lower the water's pH.) Use a few drops of liquid detergent if you aren't getting good coverage
If the plant is too large to spray completely and is in decline, you may resort to a root drench containing imidacloprid. Check in the pesticide section of garden centers and at agricultural supply stores. This should not be used on fruit trees. Strictly follow all directions and safety precautions.
Some people have removed light infestations on small plants by picking off scales. Avoid hard scraping as this can open the bark to infection. Severe pruning of fast-growing shrubs such as firebush and wax myrtle has also been used to help get ahead of an infestation, either before or after treating with oil spray. Try to seal up infected cuttings in a bag to avoid spreading. Kill them in the bag in the freezer or by baking in the sun.
Don't forget that many homemade remedies for plant problems are ineffective and more dangerous than "chemicals" on the market. Check out these concoctions with an expert before using them. The Miami-Dade Extension phone number is 305-248-3311 and their web site is miami-dade.ifas.ufl.edu.

TALKING NATIVE: Joewood – A Classy Native Tree
by Roger Hammer
One of my favorite native trees is Joewood (Jacquinia keyensis), which can be found growing wild in the Florida Keys (Miami-Dade and Monroe counties) as well as on Long Pine Key in Everglades National Park (Miami-Dade County). The tree is notoriously slow growing but this can be a benefit in the landscape by not out-growing its space in a short period of time. And what it lacks in speed of growth, it makes up for with character and a floral perfume that rivals the gardenia. It will let you know from afar when it's in flower. The small, 3/8-7/16" white flowers are produced mostly in late spring or early summer and will cover the tidy canopy. The stiff leaves are small, mostly about 5/8-1 1/2" long and 3/8-1/2" wide, with margins that curl under.
The common name is a modification of Cudjoe Wood, its West Indian name, and is the name source of Cudjoe Key in the Lower Florida Keys. Unless, of course, you believe the old Keys yarn about the man who got tired of city life in 1880s Key West and moved to an unnamed Key to seek solitude. His relatives would then go visit him on "Cousin Joe's Key." The crushed fruits of Joewood have been used to repel ants and as a fish poison.
Give this tree a prominent place in your home landscape so you and your friends can admire it. It lends itself well to small spaces and could be grown for many years in a pot on the patio, by the pool, or on either side of an entranceway. You can, of course, use it informally in a group planting with other small trees and shrubs but be sure that it will receive full sun and not get overtopped by faster growing trees. You will need to patronize nurseries that specialize in South Florida native trees to find this tree in cultivation. Try Plant Creations in southern Miami-Dade County or Florida Keys Native Nursery at Mile Marker 89 in the Upper Florida Keys. If you don't mind spending some money, have a landscaper purchase a field-grown specimen from Native Tree Nursery (wholesale only).
A good place to see wild trees is in Long Key State Park at Mile Marker 67. Just walk the nature trail until you get out into coastal berm habitat and there you will see some very old gnarled specimens with short stocky gray trunks. Some look as if they may have been around when Juan Ponce de Leon sailed by the Keys in 1521.
A DCFNPS member, Roger Hammer is a well known professional naturalist and photographer in South Florida whose most recent publication, "Everglades Wildflowers", is an essential field guide for all native plant enthusiasts, both professionals and amateurs alike. All his accomplishments in the field of native plant education and conservation could not be listed here. We are grateful for his contributions and look forward to more!
