Sustainable Displays within your Gardens:

Sustainable Displays within your Gardens Presentation by: Brent Pickering Curator of Grounds

How to Start:

How to Start Form a Team or Committee Brainstorm Combine ideas in a holistic manner Consider every angle Formulate a budget Determine timeline

Integrative Design:

Integrative Design Keep aesthetics in mind Keep a balanced garden—mix ornamentals with natives Complete a “sustainability audit”

Why Be Sustainable? :

Why Be Sustainable? Energy consumption Non renewable resources 2.2 billion gallons of fuel used just for lawn care each year Air and water pollution 20,000,000 small engines sold in the U.S. each year Noise pollution

Why Be Sustainable?:

Why Be Sustainable? Chemical usage Pesticides and Fertilizers

What can we do?:

How to be Sustainable:

How to be Sustainable Chemical use IPM Energy/ Pollution Electric Battery powered equipment Propane Plant material Remove invasive plant material

Goals of Educating the Public:

Goals of Educating the Public Educate the importance of sustainability and gain interest Give take-home examples (i.e. ideas on planning) Follow-up education (i.e. classes, handouts, symposiums)

Mission & Vision:

Mission & Vision To coordinate a continent-wide approach to plant germplasm preservation among public gardens To promote professional standards of plant collections management _______________________________________ EXCELLENCE PLANT COLLECTIONS SYNERGY -------------------------------------------------------------------------------------------------------- NAPCC is the recognized standard for excellence in plant collections management and demonstrates a garden’s enduring commitment to global efforts to save plants. NAPCC North American Plant Collection Consortium

Characteristics of an Urban Soil (Dr. Philip J.Craul,1985):

Characteristics of an Urban Soil (Dr. Philip J.Craul,1985 ) Great vertical and horizontal variability Modified soil structure leading to compaction Surface crust on bare soil often hydrophobic Modified soil pH, often alkaline Restricted aeration and water drainage Interrupted nutrient cycling Presence of man made materials and contaminants Highly modified soil temperature regimes

What happens to Urban Soils? - Compaction:

What happens to Urban Soils? - Compaction Macropores (Air) Micropores (Water) 50% pore space for air and water 50% solid matter 5% organic matter preferred This is “ I deal ” Soil

What happens to Urban Soils? - Compaction:

Resistance to root penetration Lower water availability Increased flooding & hypoxia Nutrient stress Heat stress Reduced photosynthetic rates What happens to Urban Soils? - Compaction Micropores (Water) This is “ R eality ” Macropores (Air) Solid matter

Fertilization Doesn’t Solve All of our Urban Soil Problems:

Fertilization Doesn’t Solve All of our Urban Soil Problems + ___________________________ Soil compaction Nutrient poor soils Low Organic matter No/Improper mulch Tillage Fertilization Incorporation Proper Mulch Root Invigoration™

Biochar or terra preta , is a name for charcoal created by pyrolysis of biomass such as wood waste, corn stover, switch grasses and others . Biochar is under investigation as an approach to carbon sequestration to produce negative carbon dioxide emissions. Independently, biochar can increase soil fertility, raise agricultural productivity and reduce pressure on forests, though the degree to which results offer long term carbon sequestration in practice has been challenged. Biochar is a stable solid, rich in carbon and can endure in soil for thousands of years.

“Terra Preta” in Amazonian Agriculture was Amended with Charcoal:

Disease Progression (girdling %) was reduced with biochar and further reduced with phosphite:

What DOESN’T Biochar Do?:

What DOESN’T Biochar Do? Immediate fertility effects Need to add fert and/or compost with biochar for short term effects Always act the same Soil type, moisture, source of char, plant species, and many other factors alter effects Allow us to ignore other factors This isn’t a silver bullet or a fix-all Make you skinny, grow hair, remove wrinkles, improve your sex life, lower chlosterol

Biochar Bottom Line:

Biochar Bottom Line The Future is Promising We are seeing Positive Responses in Soil Initially and Physiological Over Time -> Tree Aesthetics Buyer Beware!!! Lots of Questions

Slide Headline

Top 10 Sustainable Plants:

Top 10 Sustainable Plants Educate our guests. Smart plant selection is the single most important way to create a low-maintenance, high-enjoyment garden. Partner with area nurseries Phipps chooses 10 plants each year. Posters and Top 10 plant tags distributed to nurseries Plants and nurseries listed on web site

PowerPoint Presentation:

Top 10 Sustainable Plants Image Plants are labeled in our gardens. Over the past six years we have developed a palette of 60 plants and we’ll continue to add 10 each year. Plants for a variety of conditions sun shade Wet dry Evergreen & Deciduous trees shrubs perennials

PowerPoint Presentation:

Top 10 Sustainable Plants Image Interpretation Signage relates the sustainable plants growing at Phipps to what visitors can do in their own gardens. Adult Education Programs Sustainable Horticulture Certificate Native Plant Studies Certificate Landscape & Garden Design Certificate Numerous non-certificate classes

Top 10 Sustainable Plants:

Top 10 Sustainable Plants Plants Tags are given to nurseries to use in pots or to hang on plants.
