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 […]
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.

Rigorous scouting can help manage tip-feeding thrips before they cause irreparable damage By Lloyd Nackley and Melissa Scherr Thrips belong to the insect order Thysanoptera, of which there are several species that are damaging to nursery and ornamental crops. Whether there is only one or many, we call them thrips regardless, just like with other […]
The fight against flatheaded borers
By — Posted
Oregon State University researchers from the Nackley (nursery) and Wiman (orchards) programs have teamed up with scientists from across the country to study the biology and management of flatheaded borers. Flatheaded borers are beetles, from the order Coleoptera and the Buprestidae family, that can be devastating pests of ornamental trees grown in nurseries, transplanted landscape trees, trees grown for wood or other products, and fruit and nut crops.
