"Alternatives to Glyphosate: How Do They Compare on Annual and Perennial Weeds?"
Joe Neal, Ph.D., Department of Horticultural Science, NC State University

Joe discusses weed control. Whether you agree or disagree with recent reports of an association between glyphosate and non-Hodgkin’s lymphoma, many people are searching for alternatives for postemergence control of weeds in landscape beds. Joe will demonstrate and discuss the efficacy of alternative herbicides and "natural" products, with particular attention to efficacy on annual vs. perennial weeds.

"Designer Soil—Should We All Be Using It? and Does It Support Sustainable Plant Growth?"
Barbara Fair, Ph.D., Department of Horticultural Science, NC State University

Join Barbara Fair as she shares preliminary results of her experiment assessing the physical qualities of designer and typically amended soil and their impact on growth of two tree species.


12:00 pm–1:00 pm

Landscape Professional Sessions

1:00 pm–4:00 pm – Afternoon Indoor Sessions (Ruby C. McSwain Education Center)

"The Benefits of Developing an Economical and Sustainable Soil-building Program" Gary Gittere, NC Compost Council and McGill Compost

Rarely is there an opportunity to bring environmental and economic sustainability together than in the matching of organics recycling to the improvement in soil health. Agronomists and soil scientists have long-recognized the beneficial relationship between proper organic matter levels and improved soil health. Understanding the benefits of compost use for landscapers, professional turfgrass managers, field construction specialists, and specification writers provides the meat of this discussion. Case studies are sandwiched between a portion of the science to help managers and designers understand how using compost as a soil amendment, offers a significant amount of nutrient recycling and further improved soil health benefits, such as disease suppression, safer playing surfaces, and improved water management. Not all compost products are the same, so this session will also cover the basics of compost selection and specification to create healthy sustainable soils.

"How Using Landscape Shrub and Tree Growth Regulators Save Labor and Improve Plant Health"
Patrick Andserson, Arborologist, Rainbow Treecare Scientific Advancements

Plant growth regulators (PGRs) can be a versatile tool for managing trees and shrubs within the urban/suburban interface. Reduced pruning cycles can benefit budgets, labor allocation, and result in less frequent wounding of trees and shrubs. Modern growth regulators offer a host of secondary health benefits that improve a plant's chances of surviving in our urbanized ecosystems. During this session we will discuss the science behind PGRs, proper application, and present case studies of how PGRs can work with in landscape operations.

"How to Deliver a Successful Landscape Bid"
Paige Moody, Arbor Enterprises

Paige will break down the process of a developing a bid so your success rate is consistently high in an ever competitive market.
