WALNUT CREEK, Calif. – Valent Professional Products announced that Adorn fungicide has been registered for use on ornamentals in California. Adorn is a new chemistry that controls downy mildew, Phytophthora and Pythium in greenhouse, nursery and outdoor landscape settings.
Available for use as a spray or drench, Adorn is effective against a number of diseases affecting California ornamentals, including sudden oak death (SOD) or Phytophthora ramorum. With a new mode of action, Adorn is also an excellent addition to fungicide rotations and plays a key role in resistance management programs when used as part of a tank mix.
Adorn has low-use rates of 1 to 2 ounces per 100 gallons as a drench and 2 to 4 ounces per 100 gallons as a spray. With its translaminar activity, Adorn provides enhanced plant coverage to help ensure growers and LCOs get more from their fungicide.
A new type of sustainable and environmentally friendly potting medium made from thinned pine trees has been created by U.S. Department of Agriculture (USDA) scientists and their university cooperators.
Nursery plants are now grown in containers filled with soil-less potting medium, formally called substrate, consisting of Canadian peat moss, perlite, vermiculite and pine bark. But obtaining these materials can be costly and time-consuming, due to required energy inputs and availability.
WholeTree is a new material that can be used alone or mixed with other materials to make substrate. It was created by horticulturist Glenn Fain, formerly with USDA's Agricultural Research Service (ARS) at the ARS Thad Cochran Southern Horticultural Laboratory in Poplarville, Miss., and Charles Gilliam, a professor with Auburn University. They collaborated with research leader James Spiers and horticulturalist Anthony Witcher at the ARS Poplarville laboratory, and with Greg Young, owner of Young's Plant Farm in Auburn, Ala. ARS is USDA’s principal intramural scientific research agency.
As its name suggests, WholeTree is made from all parts of a tree, in particular the southern pine tree (Pinus taeda). But the trees aren't cut down in natural forests. Instead, the trees used to make WholeTree are harvested from tree plantations at the thinning stage, when some trees are removed to achieve a density the site can support. Once processed, WholeTree can be used as an alternative substrate.
Similar products have been available in Europe for several years, but WholeTree could be one of the first available U.S. products made from locally grown materials. According to Fain, who is now an assistant professor at Auburn University, field and laboratory studies have demonstrated the successful use of WholeTree, even at 100 percent for some nursery plants.
The scientists are further researching WholeTree's suitability for use in cutting and seedling propagation of herbaceous perennial and woody ornamental crops. So far, they have conducted tests on plants popular to the ornamental and landscaping industries.

ORANGE, Calif. – It was a simple equation. Village Nurseries, a specialty grower for landscape professionals, had a surplus of large trees in inventory. Public schools had no money to beautify their campuses. The result was Village Nurseries’ “Helping Our Local Communities Grow Green” tree giveaway for local schools.
Village Nurseries’ management had been discussing ways to get involved with their local communities. Terri Cook, vice president of human resources and risk management, suggested donating trees to local schools. Cook had become involved with nearby Nohl Canyon Elementary where her daughter attended. She spoke with the school’s principal, Dominique Polchow, who was thrilled with the idea.
Mona Lisa Borad, manager of the Village Nurseries Landscape Center in Orange, took control of the project. Village Nurseries would supply 6- to 12-foot trees in 15-gallon containers, mulch, stakes and snacks for the volunteers. The school was responsible for digging the holes and organizing families to plant the trees.
Steve Williams at the Orange Unified School District office supplied equipment to dig holes at every school involved in the program. When Borad arrived at Nohl Canyon with the trees, everything was prepared. She instructed the volunteers on how to plant and maintain the trees, and the plantings began.
“This was a great opportunity to get families involved with our school,” Principal Polchow decided. “We were very pleased with the turnout. Each family chose an area to plant. And everyone who participated got a free plant coupon plus a discount card good at any Village Nurseries location for a year. It was a wonderful event. The families and students took great pride in beautifying our campus.”
After the success at Nohl Canyon Elementary, Borad and Polchow contacted other schools in the Orange USD, and four more signed on: Jordan Elementary, Imperial Elementary, Canyon Rim Elementary, and McPherson Magnet Elementary. Tustin Memorial Academy signed on as well.
"Our campus needed sprucing up, but in this economy, we must find creative ways to improve our schools," explained Principal Jeanne Bentley of McPherson Magnet Elementary. "Village Nurseries' Grow Green program was ideal. We consider family involvement essential for student success, and through this program, we were able to bring both school and business together to improve our community. And because it was held on a Saturday, parents who work during the week had the opportunity to participate together with their children on campus. Village Nurseries’ Grow Green program was a fun filled family event, and our school looks more beautiful."
Village Nurseries’ initial “Helping Our Local Communities Grow Green” tree giveaway program ended with the school year. However, Borad is now preparing for the 2010-2011 school year and hopes even more schools will get involved.
“The Grow Green program helps Village Nurseries in two ways,” Borad says. “It allows us to reduce older stock in our inventory to make room for new trees. And, it demonstrates our commitment to the local communities where we do business. It’s something we can do. It’s something we’re good at. And it’s something our people can be proud of.”
D.S. Cole Growers' succulents were big winners at the recent Ohio State University consumer trials. The company’s Echeveria Collection was named top-ranked container. Not far behind was D.S. Cole’s Succulent Collection, which ranked third in the consumer evaluation.
D.S. Cole offers the Echeveria collection as a package of 100 young plants. including six different varieties. The Succulent Collection includes 200 liners with a selection of 12 different varieties.
Each year consumers rank their favorite combination containers at the trials. Top honors are based on performance and durability.
