7 Steps To Create Great Combos
The numbers and range of combination baskets and containers grown for spring sales have increased tremendously in in the past 10 to 15 years. An explosion of new genera and improved genetics from breeders and suppliers over the same timeframe contributed to this trend, and consumers have reacted positively. Although single variety baskets and containers are still produced in large numbers, combinations are now the primary focus at retail. With the continuing realignment of production into combination plantings, a number of factors need to be considered when planning, planting and growing these crops. Such factors include color combinations, plant vigor, plant habit, planting design, container size, cultural requirements, and flowering time. Follow these seven tips to ensure success with each factor. 1. Get Color Combinations Right Color combination refers to the designing and blending of a certain mix of colors in the finished container. This combination can be as simple […]

Technology Improves Orchid Production At Green Circle Growers
Green Circle Growers in Oberlin, Ohio, has a commitment to using production practices that are efficient and sustainable. The operation has been growing Orchids for nine years, and is entering its second full year with its current system, which entails three camera grades. “The camera grading — first at production into a 5-inch pot, then 12 weeks later and a final grade after the stem and buds have developed — is raising our overall quality,” says Wesley Van Wingerden, director of growing for Green Circle Growers. Greenhouse Grower visited the operation to take a tour of its facilities and learn more about its Orchid production. Read on for more details about the process. The first of the camera grades is incorporated into the transplant process, which involves placing the Orchids from a community tray into 5-inch pots. The plants are separated into three sizes with the smallest returning to the […]

Vivero Internacional Continues To Expand Unrooted Cuttings Production In Mexico
The tenth largest cuttings farm in the world, Vivero Internacional was founded in 1991 and began exporting unrooted cuttings in 1993. Based in Tepoztlan, Morelos, just outside of Mexico City, Mexico, the operation opened with 2 hectares or 5 acres. With time and new customers, the farm has experienced rapid growth, now spanning 40 hectares or 99 acres, says Vivero’s Dennis Hitzigrath. “The first 10 years, production was doubling every season,” Hitzigrath says. “In the last three years, it’s been about 20%.” The independent operation grows 100 million cuttings annually for several breeders, serving the North American market. Hitzigrath says consolidation among breeders has brought more of a focus on Vivero Internacional from third-party breeders in recent years. This growing interest is spurring even more growth. “We are planning for a minimum growth of 20%,” Hitzigrath says. “We are adding more production space and hope to be needing more […]

Backyard Success: Mike McGroarty Educates Aspiring Growers
Mike’s Backyard Nursery sits on a long, narrow, 5-acre property located in Perry, Ohio. There, customers can find a variety of flowering shrubs available, all in 2-quart pots, and all for sale for $5.97 each. Owner Mike McGroarty, a lifelong resident of Perry, says the town has a lot of plant nurseries, including 100 wholesale growers within a 10-mile radius of his house. That doesn’t discourage McGroarty, because he knows that while there are a lot of nurseries in his area, no one else is doing what he is doing. McGroarty has learned about plants — and marketing them to his audience — through decades of experience. He has never hesitated to pass along his knowledge to other growers looking to start their own backyard operations, and has created an entire program to educate aspiring growers. McGroarty Likes To Practice What He Preaches McGroarty’s operation serves as the laboratory for […]

Concern Grows Over Unregulated Pesticide Use On Cannabis
As most growers know well, the federal government regulates all insecticides, fungicides, herbicides and other commercial chemicals used on agricultural crops. Therein lies the problem with use of chemicals on cannabis crops – so far, the feds want nothing to do with legalized marijuana. According to “Concern Grows Over Unregulated Pesticide Use On Cannabis,” a June 17 article on the National Public Radio (NPR) network by Agribusiness Reporter Luke Runyon, the lack of regulated chemicals for cannabis has left growers to experiment on their own. “In the absence of any direction the subject of pesticide use on the crop has just devolved to whatever people think is working or they think is appropriate,” said Colorado State University Entomologist Whitney Cranshaw in the NPR report. “Sometimes they’ve used some things that are appropriate, sometimes unsafe.” Denver officials held tens of thousands of marijuana plants earlier this year due to safety concerns, but […]

The Butterfly Effect: Insect’s Wings Key To Azalea Pollination
A researcher from North Carolina State University (NC State) has found that in the case of the flame azalea (Rhododendron calendulaceum), all pollinators are not created equal. In fact, due to the flower’s unique reproductive structure, butterflies — and specifically, their wings — are the key to pollination. The flame azalea is commonly found in the Appalachian Mountains, ranging from as far north as New York to Georgia in the south. Like most azaleas, the flowers are large, and have an unusual structure: both the anther (male) and stigma (female) parts are very elongated and separated from one another. NC State biologist Mary Jane Epps was interested in how the azalea’s flower structure affected its pollination. “In order for a plant to reproduce, a pollinator — usually an insect — has to spread the pollen from the anther to the stigma,” Epps says. “In the case of the flame azalea, […]

4 Key Pollinator Research Projects To Be Funded By Horticultural Research Institute
The Horticultural Research Institute will grant $125,000 in financial support for four key projects as part of the Horticultural Industry Bee & Pollinator Stewardship Initiative. The Initiative has three primary goals. First, to convene a task force to develop a bee and pollinator stewardship program, including creation of best management practices for plant production. Second, to identify and fund research that will help answer key science questions and fill gaps needed to design and refine the stewardship program. Third, to seek to positively position the horticultural community and its customers by collaborating with other compatible groups interested in augmenting pollinator habitat and protection.
