Across horticultural crops the trend is to transplant larger plants to achieve the intended landscape effects or to produce the desired yield without the long wait associated with direct seeding or small transplant technology. Consumers want immediate gratification (a landscape design that produces the desired aesthetics without the wait for plants to grow to mature sizes). This trend extends from the use of large herbaceous plants for instant landscape color, transplanting of vegetable plants already in fruit to the home garden for early yield, to transplanting larger shrubs and trees to effect the impression of an established landscape. This trend logically culminates in the transplanting of large, mature specimen trees to create the appearance of a fully mature landscape. This workshop will explore the potential benefits of this approach and the challenges associated with successful transplanting of large trees.

Studies have demonstrated that the size of transplanted trees has a measurable impact on establishment rates in the landscape. Larger trees require a longer period of time than smaller trees to produce a root system comparable in spatial distribution to similar sized non-transplanted trees. This lag in redevelopment of root system architecture results in reduced growth that increases with transplant size. Research has demonstrated that smaller transplanted trees become established more quickly and ultimately result in larger trees in the landscape in a few years. Additional studies dispute these findings. This paper provides a review of current research on the effect of tree size on transplant establishment.

Funding reductions have left many Extension field and specialist positions unfilled when they are vacated. In New England, severe economic downturns have made this situation acute and have forced Extension programs to find innovative and more efficient ways of delivering information to clientele groups. The nursery and landscape industries comprise a major agricultural sector in New England whose needs must be met to maintain agriculture in the region. Yankee Nursery Quarterly was developed as a regional effort to draw upon nursery and related expertise from the six New England states. Yankee Nursery Quarterly provides information in the areas of nursery and Christmas tree production, landscaping, arboriculture, garden center operation and turfgrass four times annually. The publication format deviates from the standard 8 ½″ by 11″ size and uses 2 color printing, a four-column layout and black and white photography to provide a recognizable, informative and visually appealing product.

DACUM (develop a curriculum) was implemented at Kent State University (KSU) to develop and revise curricular content of an associate degree program in horticulture technology. Initially, at KSU-Salem in 1990, a committee followed a typical DACUM process to develop a skills profile for the horticulture technology worker. The skills profile consisted of terminal and intermediate learning objectives that served as the content of basic data sheets for thirteen new courses in horticulture technology. This associate degree program was initiated at Salem in 1991 and offers three concentration areas: landscape management, turfgrass management, and arboriculture. Later, when a proposed new program offering was considered at KSU-Geauga, a modified DACUM process was implemented to develop a new skills profile that refl ected both general knowledge areas of horticultural and business practices and industry-spe- cific competency areas. Comparison of the two curricula revealed similarities between the two skills profiles. This led to the recommendation that the original curriculum also be offered at KSU-Geauga campus with two differences: 1) omit the arboricul- ture concentration, and 2) consider a new concentration in greenhouse and nursery operations in the future. The associate degree program in horticulture technology at the KSU-Geauga campus began in 1999. The DACUM process, by involving members of the horticultural industry in the curricular development process, provided several long-term benefits and a high level of cooperation between industry leaders and KSU-Geauga.
