OFA Short Course Greenhouse Tour At A Glance
Participants in the OFA Short Course Grower Learning and Diagnostic Tour took a look at two operations, Krueger-Maddux Greenhouses in Sunman, Indiana, and Diefenbacher Greenhouses in Cincinnati, Ohio. At each facility, university researchers were also on hand to present mini clinics on scouting, lighting, nutrition and other production issues. Just one section of the 8-acres of outside growing area at Krueger-Maddux Greenhouses. A bioremediated water system provides the 25 million gallons of water used annually. Diefenbacher Greenhouses is a 4-acre operation in Cincinnati, Ohio that supplies bulbs, Easter lilies, annuals, fall crops and poinsettias to independent garden centers, landscapers and retail florists. Roberto Lopez of Purdue University demonstrates how light levels can change dramatically depending on the location in the greenhouse. Filled pots are stacked with dividers in between layers to distribute the weight and avoid compaction of the media. Simple wire holders that hold four 8-inch pots each increase […]

Tips For Producing Leucanthemum
Leucanthemum, or Shasta Daisy, has always been a favorite of gardeners. The simple daisy flower has great appeal, and they are fairly easy to grow. The name Shasta Daisy was designated by the breeder, Luther Burbank. He named his new hybrid after Mt. Shasta, a snow-capped mountain in northern California. The name Leucanthemum is derived from the Greek words leukos, “white,” and anthemon, “flower.” In recent years there has been a boom in the breeding of Leucanthemum and the development of new petal colors and forms. Green Fuse Botanicals has three distinct varieties in the First Light Perennial collection. All three varieties are first year flowering, requiring no vernalization. Consequently, they can be received later in the growing calendar, greatly reducing crop times. These perennials will also flower continuously through the first spring/summer, allowing the grower to produce them any time during the growing season. With a bit of plant […]

Impatiens Are Not Down And Out
Impatiens — it’s not only a plant genus; these days, it’s a state of mind. With confirmed reports of Impatiens Downy Mildew in more than 20 states as of July 31 and disease pressure in 2013 expected to be worse, the industry is beginning to understand just how serious this issue could be for producers who grow one of the most popular bedding plants in America. “Impatiens avoidance behavior will largely be seen for the first time in 2013,” says Cornell University Plant Pathologist Margery Daughtrey. “More outbreaks are occurring all the time that will continue to affect customer demand next spring. The amount of inoculum available in the trade and in the garden beds will interact with the spring weather patterns to determine what will happen next year — and those are all unknowns.” But it’s not all bad news. Growers who preventatively treated for Impatiens Downy Mildew and […]
