Many homeowners that strive to attain aesthetically pleasing landscapes will err on the side of over application of fertilizer rather than insufficient application ( Israel and Knox, 2001 ). However, there are potential environmental consequences of

Information on the Internet relative to the landscape and nursery industries is rapidly expanding. However, finding reliable sites on subjects of interest to the field of commercial landscape horticulture is a difficult task. PLANT: Purdue Landscape and Nursery Thesaurus, is an extensive database of links to Internet information for professional landscape contractors/managers and nursery growers in Midwest and Northeast states. PLANT currently consists of 21 independent pages on topics from “Computer Software” to “Winter Hardiness”, with >2500 links to appropriate Internet information. A search mode allows one to search the database by key words as well. This extension-based tool is also an excellent resource for class assignments in the area of ornamentals and landscape horticulture. As a work in process, PLANT is regularly updated and expanded to provide multiple sources if Internet information on topics of interest to the landscape and nursery industries. PLANT can be found at bluestem.hort.purdue.edu/plant/.

The personalities in a population of landscape horticulture graduates at a 2-year technical college were found to be similar to those in a population of landscape company managers. However, the personalities of the landscape company managers do differ from those in a general population of college students in terms of their information acquisition, decision making, and lifestyle preferences. The typical landscape company manager in the population surveyed was found to be a 41-year-old male with a bachelors degree. This individual had been employed in the occupation for 20 years, worked ≥41 hours per week, and rated job satisfaction as high.

Water conservation in a landscape is an important issue because periodic water shortages are common in many regions of the world. This increases the importance of specifying landscape plants that require less water and matching the plant to site microclimates. Our objectives were to establish water-use rates for three herbaceous landscape plants and to determine the level of water reduction these plants can tolerate while maintaining both visual and landscape quality. Water use rates were determined for Schizachyrium scoparium (Little bluestem), Hosta spp. (Hosta) and Festuca cinerea `Dwarf' (Dwarf blue fescue) in studies using pot lysimeters at the Univ. of Nebraska Horticulture Research Greenhouse facility. Each lysimeter was watered to saturation, allowed to drain to field capacity, and weighed. The lysimeters were weighed again 24 h later, and the process was repeated to determine daily evapotranspiration. Results indicated that hosta used less water than dwarf blue fescue and little bluestem. In a subsequent study to compare the relative effects of withholding irrigation among these species, seven groups of five replicates of each species were grown in 1 peat: 0.33 vermiculite: 0.66 soil: 1 sand (by volume) in 7.6-L containers. Each container was watered to saturation, allowed to drain for 24 h to reach field capacity, and allowed to dry down in 10-day increments. Results of the dry-down study indicated that little bluestem maintained the best visual quality for the longest duration of drought, followed by dwarf blue fescue and hosta in decreasing order of visual quality.

Root systems of most nursery-grown landscape trees extend well beyond the edge of the canopy. As a result, when large (greater than 2 m tall) field-grown trees are harvested for transplanting, only a small portion of the root system is moved and a
