The California Oak Mortality Task Force, during a March 17, 2004 meeting at Sonoma State University, announced that Phytophthora ramorum, a fungus that causes sudden oak death (SOD) was found on camellias at Monrovia Nursery, in Azusa, just east of Los Angeles. It’s reportedly the first time the disease has been identified in a Southern California nursery.
Said to be the largest horticultural nursery in California, Montrovia Nursery has been in business for 76 years and produces more than 2,200 varieties of perennials, conifers, woody ornamentals, shrubs, trees, citrus, camellias, rhododendrons, vines, ferns, grasses and topiaries. Other than the home nursery in Azusa, it also operates nurseries in Dayton, Oregon, Visalia, California, Springfield, Ohio, La Grange, N.C. and Cairo, Georgia. These wholesale nurseries, covering some 4,724 acres, ship plants to more than 5,000 garden centers nationwide.
The California Department of Food and Agriculture has the job of trying to identify any potentially infected material that might have shipped in the last year. The disease has reportedly been found in more than 40 plant species worldwide.
All host plants at the Monrovia Nursery are to be inspected and plantings within 10 meters of infected plants will be on hold for 90 days. The pathogen was reportedly traced from shipments from Washington state to Southern California.
The California Oak Mortality Task Force reports that coast live oak (Quercus agrifolia), tanoak (Lithocarpus densiflorus), and California black oak (Quercus kelloggii) are dying in large numbers in central coastal California due to SOD. The fungus affects many other tree and shrub species, including rhododendron species, California bay laurel (Umbellularia californica), huckleberry (Vaccinium ovatum), and California buckeye (Aesculus californica). There are 38 species susceptible to the fungus, 22 of which are identified as hosts by the USDA. (The list is available at www.suddenoakdeath.org.) The plants most likely to be spread the fungal infection are the California bay laurel, Oregon myrtle and Rhododendron spp.
The task force had confirmed back in October 2002 the presence of the pathogen in at least 12 California counties. The infection may occur on the trunk and branches (cankers) or on leaves (leaf spot). Infection does not necessarily result in death of the plant, the task force points out; mortality occurs when the cankers expand in the truck.
The fungus thrives in cooler, wetter climates. In California, it is found only in the coastal counties.

Trees Florida 2004, June 12-15 in Key West, is expected to be the largest tree conference ever held in the state. About 500 attendees are anticipated, including professional arborists; urban foresters; landscape architects; planners; engineers; nursery operators; horticulturists; educators and, of course, vendors.
The Florida Urban Forestry Council will join with the Florida Chapter International Society of Arboriculture, and the University of Florida Extension to present top-rate educational programs, an industry trade show, field trips, and outdoor workshops.
Thirty speakers will be on hand, and attendees will choose from breakout sessions designed to address the concerns of professionals involved in the Florida tree industry. This will be the place to learn the latest in arboriculture research and education, and to see the latest equipment and tools.

Washington, D.C. – The American Nursery & Landscape Association (ANLA) recognized the 21 graduates of the Garden Center University (GCU) class of 2004 at the annual Management Clinic in Louisville, KY. GCU, taught and directed by Ian Baldwin, is a training program designed for managers to learn to create a more profitable, efficient and customer friendly garden center. The graduates are business professionals ranging from veteran garden center owners/managers to those relatively new to the industry.
“GCU is sort of a mini-MBA for garden centers,” explained Mr. Baldwin. GCU is a five-step program, completed over two years that targets retail owners and managers in the sales volume range of $500,000 to $5 million per year, who want to double or triple their size. In addition to class instruction, participants visit and network with owners of super league stores, attend trade shows, and go on buying trips. The key learning areas in the program are strategy, fiscal management, operational management, interpersonal skills, and service and sales expertise.
“GCU is a combination of many invaluable tools that help me make better and smarter business decisions,” said graduate Mike Diacont, of Wildwood Nursery and Garden Center(NC). Graduates identified financial analysis skills development and networking as the greatest benefits of the program.
“It was invaluable learning how to make sense of all the financial numbers generated in our business and what to do with them to grow,” offered Bryan Foushee of Spring Meadow Greenhouses, North Carolina.
“GCU inspired a group of friends, with common professional interests and goals, to grow into an unbelievably generous, helpful, source of ideas, advice and sound business practices,” said Tom Tinguely of The Great Outdoors, Texas.
The classes of 2005 and 2006 are already underway, each enrolling over 35 students. Garden center owners and management professionals interested in GCU classes of 2006 or 2007 may contact Melissa Strickland at 202-789-2900.
Construction has resumed at Miami’s new Japanese Garden on Watson Island, weeks after the contractor walked off the job because he wasn’t paid.
Last December, Landscape contractor, Sunhouse Construction, quit work on Miami’s new Japanese Garden on Watson Island after cost disputes between Parrot Jungle Island and the city of Miami held up a $312,000 payment.
Last month, Sunhouse resumed work after the city remitted full payment. City administrators have indicated that the work is now moving along quickly and should be completed in time to make the original April 29 dedication.
The $1 million garden is months behind schedule. The November 2003 death of the design landscape architect, Lester Pancoast, posed problems, and when disagreements between the city and Parrot Jungle broke out over the scope of the work Parrot Jungle was responsible for, construction began to stall.
Parrot Jungle’s owners sought to revitalize Miami’s old Japanese Garden under a 1997 agreement allowing Parrot Jungle to build on city-owned land on Watson Island.
Construction on the project began before signing a contract specifying each party’s share of the project cost.
According to statements from Laura Billberry, the city’s assistant director of economic development, both the city and Parrot Jungle recently signed an agreement setting Parrot Jungle’s financial responsibility at $350,000, which includes the cost of plantings and installing an irrigation system, the last items of remaining construction.
The city’s share of the project cost, comes in at around $650,000, that was compiles from grants and safe-parks bond money. Some of this grant money was at risk because of the work walkout. But with work now resumed, Billberry has indicated that she is ‘’optimistic’’ that the city can salvage $154,000 in grant money designated for the project.
