Monday, July 6th, 2020 | 1:00 - 2:30 PM EST | Design

Ecological design need not be a bitter aesthetic pill that our clients must swallow to do the right thing. The order inherent in our wild native landscapes is widely considered beautiful. By translating that ecology-based order into the aesthetically-based language of fine garden design, the results can be more universally embraced by our clients. Larry will illustrate how this confluence of approaches can yield landscapes that are both ecologically productive and beautiful.

Wednesday, July 8th, 2020 | 1:00 PM - 2:30 PM EST | Design

Some of America’s oldest and most noted cemeteries are pioneering naturalistic plantings to replace traditional lawn. These plantings enhance visitor experience while providing habitat and other important ecosystem services. Learn what it takes to make these layered, dynamic plantings successful within the cemetery context and understand how such plantings can align with the aesthetic traditions of memorial landscapes.

Thursday, July 9th, 2020 | 1:00 PM - 2:30 PM EST | Design

Many ecology-based field techniques run counter to traditional practices and are unfamiliar to even highly experienced contractors. Consequently, highly precise specifications are crucial. This presentation will cover the documentation of field procedures unique to ecological design and restoration such as phased planting, meadow seeding, and weed control procedures. We will also discuss organizational formats for specifications that distinguish between short-term and long-term management and balance the need for both detail and usability.

Tuesday, July 14th, 2020 | 3 hours | Design 

Part 1 | Historical Ecology: Revealing and Incorporating a Site’s Story into Design (1:00 - 2:15 PM EST)
Michael Gaige

Every landscape has a story that can be teased out using both field evidence and archival resources; and the vegetative legacy of that story usually remains today. This session explores case studies that demonstrate how the connection between past human activity and today's vegetative composition can inform our design interventions.

Part 2 | Then and Now (2:30 - 3:45 PM EST)
Larry Weaner

Pre-industrial cultures had no heavy equipment, herbicides, or inorganic fertilizers to plant or manage the landscape - tools that many now seek to avoid. They did, however, hone skills over millennia that displayed a sophisticated understanding of nature and its response to human activity. Explore how traditional practices may provide solutions to some of the horticultural, ecological, and even artistic challenges that today’s landscape practitioners face.   

Part 3 | Panel (4:00 - 4:30 PM EST)

Our two presenters, one a landscape designer and the other a historical ecologist, will discuss how contrasting, yet complementary disciplines can work in tandem to enhance landscape projects. Part 3 will conclude with a question and answer session with both presenters.

*Registrations are inclusive of ALL 3 of this webinar's parts. No parts sold separately.

Wednesday, July 15th, 2020 | 1:00 PM - 2:30 PM EST | Design

The creative gifts of African Americans to landscape design and ornamental horticulture are rarely acknowledged and when they are, they’re often relegated to an agricultural narrative. This presentation reveals the rich 400-year legacy of how African American culture has shaped both the American landscape and our horticultural traditions.

Thursday, July 16th, 2020 | 1:00 PM - 2:30 PM EST | Design

Carbon Farming is farming in a way that reduces greenhouse gas emissions or captures and holds carbon in vegetation and soils. It is managing land, water, plants, and animals to restore ecosystems, ameliorate climate change, and provide nutrient-dense food and educational opportunities. Also described as Regenerative Agriculture, these goals are achieved through a focus on lower-sequestration strategies like no-till organic annual cropping, perennial crops, and managed grazing. Chad will discuss the designer’s role on projects from a small urban yard to hundreds of acres.

Wednesday, July 22nd, 2020 | 1:00 PM - 2:30 PM EST | Design

Despite its visual focus, landscape design has much in common with music composition. Composers lead their listeners on an aural journey. Designers conduct movement along a garden path. Both unfold sequentially over time. In part one, designer and composer Larry Weaner will explore how the techniques of music composition can enhance garden design. Part two will cover improvisation, response to spontaneous events, and the incorporation of ambient sound, all common to jazz and modern music, as well as “wild” landscape design.

Wednesday, August 5th, 2020 | 3 hours | Plants

Part 1 | Doug’s Place: Plants and Animals in Concert (1:00 - 2:15 PM EST)
Douglas Tallamy, Ph.D.

Dr. Douglas Tallamy will illustrate how the experiences and observations at his home landscape have enhanced and confirmed his widely acclaimed research on the specialized relationships between animals and plants. Using his home property for examples, Douglas will explain why this is so, and describe how native plants can be selected and arranged in a manner that supports these food relationships, and increases the habitat value of our projects.

Part 2 | Living in a Garden Ecology Lab (2:30 - 3:45 PM EST)
Larry Weaner, FAPLD

Landscape Designer Larry Weaner has observed and interacted with ecological processes for over 30 years on his small, third-of-an-acre suburban property. Learn how this experience led to a “brains over brawn” landscape approach, one that incorporates natural succession, the reproductive abilities of plants, and the artistic editing of spontaneous vegetation.   

Part 3 | Panel (4:00 - 4:30 PM EST)

Through the lens of their respective disciplines, Larry and Doug will compare notes on how to best communicate the challenges and rewards of melding habit creation and garden design to both expectations of clients and the general public, to be followed by a question and answer session involving both presenters.

*Registrations are inclusive of ALL 3 of this webinar's parts. No parts sold separately.

Thursday, August 6th, 2020 | 1:00 PM - 2:30 PM EST | Field

How do you turn around a weed-infested landscape when many of the necessary steps conflict with imperiled bird species already using that very landscape? Learn how a unique planting and management plan for a 100-acre grassland atop a capped landfill negotiated this challenge by synthesizing crowdsourced data, scientific research, field experience, and a vision steeped in site history.

Tuesday, August 11th, 2020 | 1:00 PM - 2:30 PM EST | Plants

Although designers rarely use native annuals, knowledge about this suite of plants offers numerous design applications, including seeding them in as placeholders, nurse crops, and gap fillers in response to disturbance. Explore a variety of native annuals, their biology, and uses in designed landscapes.

Wednesday, August 12th, 2020 | 1:00 PM - 2:30 PM EST | Plants

Are straight species grown from seed always the best choice? Are cultivars always bad? Our opinions of both are often colored by the limited genetics in the nursery trade; but many species are far more genetically diverse. Even cultivars can have illuminating stories to tell. This lecture will explore the practical implications of genetic variations, ecotypes, cultivars, and the real impacts these can have on how a plant will look and behave in the landscape.

Thursday, August 13th, 2020 | 3 hours | Field 

Part 1 | Prairies (1:00 - 2:15 PM EST)
Marc Pastorek

When it comes to native prairie restoration, Mississippi horticulturist Marc Pastorek is the real deal. For over 20 years he has collected local genotype seed for his projects from wild populations and his own cultivated seed plots. He will illustrate protocols for developing species lists, locating wild stands for collection, practical and ethical harvesting, establishing cultivated seed source plots, processing and storing seed, and ultimately, how he plants a prairie.

Part 2 | Woodlands (2:30 - 3:45 PM EST)
Ian Caton

The germination requirements of woodland herbs are typically more complex than those of the prairie. In addition, the length of time that most woodland herb seeds remain viable is much shorter. In this session, landscape designer and native plant expert Ian Caton will discuss the unique protocols needed to successfully establish a seeded woodland ground layer. Topics covered include: how to identify ripe seeds; collection, storage, and sowing protocols; the use of live plants as seed sources for future colonization; and techniques for assisting native herb seed dispersal.

Part 3 | Panel (4:00 - 4:30 PM EST)

Sharing years of experience, our two speakers will discuss how the green industry can better provide for the expanded use of seed as a landscape planting option, and how designers can best make use of the seed suppliers, equipment, and labor sources that are currently available. The session will conclude with a question and answer session including both speakers.
