A sustainable landscape is more than exterior decoration. By using less water, fertilizer, and pesticides than a traditional
landscape, it has minimal impact on the environment. Thus, it is both aesthetically pleasing and environmentally sound.
Creating a sustainable landscape means working toward a thoughtful balance between resources used and results...

This publication gives basic information on choosing your
planting site, selecting the right species for the site, proper planting
techniques, and first-year care. Although you may be buying a tree
to add beauty to your home landscape,trees also serve other important
functions in your landscape.
Species selection is a complex process that forage producers and land managers face. Accurate tools and educational materials are needed to help make the decision process easier. Crop simulation models are one tool that could be utilized to predict yield and potential financial return of various species. Two crop simulation...
Many garden and landscape plants
are susceptible to one or more plant
diseases. Diseases can reduce the yield
of fruit and vegetable crops and disfigure
ornamental trees, shrubs, and
flowers.
Index selection provides an efficient means of conducting selection on multiple traits by combining information on economic value,
heritability, and the genetic and phenotypic correlations between traits to improve overall merit. The use of this method in forestry has been hampered by the lack of knowledge of the relative importance...

A wide variety of materials are sold as mulches and used in landscapes. This publication discusses mulching woody ornamentals (trees and shrubs) with organic materials. It covers the reasons for mulching, how to apply mulch, and how to maintain its beneficial effects over time. The information is presented in a...
Lasting, effective solutions to nitrogen (N) loss from container nurseries must
address layers of complexity ranging in scale from whole system nursery management
to gene expression. Group-based On-site Active Learning (GOAL) was developed to
aid nursery managers and related stakeholders (e.g. neighbors, policy makers,
regulating agencies, researchers) in developing a...
Oregon is a gardener’s dream. Our varied climates and mild conditions allow us to showcase a wide variety of plants from around the world. In fact, nursery crops are Oregon’s number one agricultural commodity.
Unfortunately, a few plants used in gardens and landscapes cause serious
ecological harm by ‘jumping the...
Plants need an adequate level of nutrients to thrive. This publication will help you ensure that your plants receive ample
levels of all nutrients for optimum yield, quality, and aesthetic value.
Although many people enjoy deer, these animals can be destructive to gardens, orchards, and landscaped areas. Deer damage to ornamental plants is associated with a variety of factors including increasing numbers of deer, human population shifts to rural and suburban areas, and landowners prohibiting deer hunting.
As ornamental container nurseries face diminishing water allocations, many are looking to automated irrigation solutions to increase their water application efficiency. This thesis presents the findings of a study conducted at a commercial container nursery to determine 1) whether a capacitance or load cell sensor was better suited for monitoring...
Rhododendrons and blueberries are popular
plants in home gardens in western Oregon and
Washington. Both are easy to grow in most
gardens, but problems with growth can occur if
the soil is not sufficiently acidic. Even in the
naturally acidic soil west of the Cascade Mountains,
soil often is not...
The three essays in this dissertation progressively answer the following questions: (a) How important are constraints? (b) Who benefits from removing constraints? (c) When does a constraint for a single market predominantly affect closely related markets? These questions are applied in the context of time, weather, and minimum wage constraints,...
