Growth, challenges, and the road ahead for the nursery industry
By — Posted
Jeb Fields, and Ryan Contreras In a recent article published in HortTechnology, titled “How Natural Resources, Consumer Perceptions, and Labor Are Transforming the U.S. Nursery Industry,” nursery science researchers from across the United States examined the current state and future of the nursery industry. The paper, available free online (TinyURL.com/IndustryPaper), highlights the substantial economic impact […]
Highlights from the 2024 Oregon Nursery Science Summit

Participants get update on research, insect and pest management and plant selection and production
OSU Ornamental Plant Breeding Program developing new cultivars for city settings
By — Posted
Lloyd Nackley and Carolyn Scagel Since 2009, the The Oregon State University Ornamental Plant Breeding Program has been dedicated to developing seedless varieties of resilient plant species that were previously considered invasive. This approach is crucial because when we introduce plants to urban and suburban areas, we need them to thrive despite facing challenging conditions […]
New tools to forecast boxwood blight infection risk in Pacific Northwest nurseries
By — Posted
The protection of boxwood in Oregon depends on precise timing of surveillance, monitoring, and management of boxwood blight infections.
Researchers at Oregon State University are testing pots made from recycled materials
By — Posted
The industry needs sustainable solutions to reduce plastic waste and an alternative is the use of plantable biopots without separating biopots before planting, which favors microbial biodegradation.
Update on flatheaded borer management in specialty tree crops
By — Posted
In 2020, a multi-state research project led by Drs. Karla Addesso and Jason Oliver of Tennessee State University was funded by the USDA-Specialty Crop Research Initiative to coordinate research on this pest group.
Exploring stratified substrates and soil hydraulics in agricultural science
By — Posted
Stratified substrates involve arranging potting media of varying textures in layers within a single container. This structured layering entails placing coarser-textured substrates at the bottom and finer-textured ones on top, mimicking natural soil layers.
PACE courses coming for nursery, greenhouse IPM
By — Posted
The Nursery Program at the Oregon State University Northwest Extension Center in Canby, Oregon, will soon be offering online courses for Pesticide Applicator Continuing Education Credits (PACE) and to the nursery community at large. The upcoming PACE classes are intended to provide more industry-specific information about strategies for pest management in greenhouses and nurseries, and […]
Pulse electric field technology may be a viable pest control alternative to methyl bromide
By — Posted
Pulse electric field (PEF) employs bursts of high-voltage electricity to inactive microorganisms. Primarily used in the food industry, some researchers have reported promising results in nematode and plant disease control (Riga et al. 2020). We are collaborating with Lisi Global to adapt an existing technology for a new use in the ornamental nursery industry.
