1:00 p.m.New & Improved Crabapple Selections for Midwestern Landscapes; Jeff Iles, Ph.D., Professor and Chair of the Department of Horticulture, Iowa State University
Crabapples (Malus spp.) are among the most popular flowering trees in any Midwestern landscape. And over the years, hundreds of selections have made their way into the nursery trade, but not all have lived up to expectations. In this session Jeff Iles will feature a few old, and many brand new crabapples that will have a positive and lasting impact on our important commercial and residential landscapes.

2:15 p.m.Pay it Forward: Selecting and Managing Elms in Your Urban Forest; Chad Giblin, Arborist and Owner, Trees & Me
Disease-resistant elms offer great benefits for our urban forests like quick establishment, fast growth, and tough-as-nails street cred, but are you ready for the challenge of including them in your inventory? Join Chad for an in-depth session that takes a look at a few elms that you might want to consider and how to manage them for multi-generational lifespans. Species selection and developmental pruning strategies will be discussed along with suggested pruning cycles for public and private spaces.

1:00 p.m.Urban Soil Remediation—Dealing with Compaction After Development and Construction; Nina Lauren Bassuk, Ph.D., Professor, Cornell College of Agriculture and Life Sciences
Soils in urban environments after construction are degraded and their ability to foster quality plant growth is diminished. Typical conditions include: high bulk density, decreased microbial activity, reduced levels of organic matter, poor structure, low water holding capacity, decreased aggregate stability, and inadequate volume for root proliferation. The Scoop and Dump method of soil remediation is a technique for reclaiming or improving sites that exhibit these conditions by reconstructing the profile through fracturing and incorporation of organic matter. The use of CU-Structural Soil is another technique that can be used when compaction is necessary to support load-bearing pavements. The goal of both these techniques is to improve the physical properties of urban soils that support healthy plant growth and foster ecosystem benefits.

2:15 p.m.Plant Growth Regulators for Lawns and Landscapes; Doug Soldat, Ph.D., Professor, UW-Madison
UW-Madison has been a leader in researching growth regulators for turfgrass. Traditionally, the use of growth regulators has been confined to the golf course sector, but research data suggests they could be a valuable tool for managing lawn and landscapes as well.

Wednesday, February 17

1:00 p.m.Diagnosing and Managing Wisconsin’s Top Ten Landscape Diseases; Brian Hudelson, Ph.D., Director, Plant Disease Diagnostic Clinic, UW-Madison Extension
Learn about the top diseases that were diagnosed at the UW-Madison Plant Disease Diagnostics Clinic during the 2020 growing season. This presentation will provide tips on diagnosing these diseases, as well as information on their control.

2:15 p.m.Mold or Bug? Differentiating Between Disease and Insect Damage on Turfgrass; Paul Koch, Ph.D., Turfgrass Specialist, UW-Madison
Insects and diseases can both cause significant damage to turfgrass lawns in Wisconsin, but managing insects vs diseases requires different strategies. In this talk we will focus on the primary insect and disease pests on Wisconsin lawns, how to identify and differentiate between the two groups, and how to properly manage them.

Wednesday, February 24

1:00 p.m.Understanding and Managing Wisconsin’s Most Menacing Landscape Insect Pests of 2020; PJ Liesch, Entomologist, UW-Madison Extension
Every year, insects cause significant problems for landscape trees and shrubs in Wisconsin. In this talk, we’ll review some of the main insect stories of 2020, including trending pests that will impact us in the coming years.

2:15 p.m.Consumer Trends in Perennials and Annuals; Kevin Roethle, Sales Representative, Ball Seed
Every year plant breeders around the world continue to bring new and exciting plants to market. This offers gardeners interesting and better options to keep their garden new and growing. This talk will highlight some of the best new plants and plant trends for your garden in 2021 and into the future.
