Steve Foltz’s Ohio Nursery Short Course presentation Throw Down Panel – Native, Potential Invasives, LEED is on Tuesday, January 25, 2011 at 10:45-11:45 ET. If you have been keeping up with Steve’s article Sustainability of Native and Non-Native Plants, January 2010, pp. 26-31, in the American Nurseryman or heard his recent presentations you know he is on a sustainability roll and he has opinions about native plants and what constitutes an invasive plant. This panel discussion sounds like fun. As always the OSU Nursery Short Course offers a great program.

Dr. Amy Fulcher starts her faculty position at the University of Tennessee, Knoxville November 1st. She will be the Sustainable Ornamental Plants Extension/Research faculty member of the Department of Plants Sciences (previously Plant Sciences and Landscape Systems). In the future you will be able to find her new e-mail address at http://plantsciences.utk.edu/faculty.htm. That she will be missed is a gross understatement. I do not know of anyone so dedicated to nursery production and the people that own, manage, and work in nurseries. Her passion is expressed by her excellence. Congratulations Amy; your excellence is recognized in Kentucky and far beyond its borders.

You will have an opportunity to visit with Amy and offer your congratulations on completion of her Ph.D. and securing her UT faculty position at the The Kentucky Nursery and Landscape Association’s Eleventh Annual Summer Outing which will be September 8, 2010 at Ammon Wholesale Nurseries, 6089 Camp Ernst Road, Burlington, KY 41005. Dr. Fulcher will be speaking on “A Horticulturist’s Perspective on Scale Pests of Woody Plants”.

Carey Grable, Extension Associate for Nursery Crops, has set up a Blog/WIKI UK Nursery Crops IPM.

Ever since I saw a picture of the fruit of a female Sassafras albidum on the cover of Wharton and Barbour’s Trees & Shrubs of Kentucky I wanted to get a picture of my own. Well, every year I was too late. I was going by resources that said the fruit ripened in August, even September. This year I altered my morning walk several times a week to pass a female plant in a thicket. Then I found another plant with better foliage nearby. Images I took July 30 & 31, 2010 are on-line at: http://www.ca.uky.edu/HLA/Dunwell/SassafrasalbidumWDunwell.html

I post Amy Fulcher’s Nursery Update and Carey Grable’s Western Kentucky Nursery Crop Update and try to announce to one and all that they are there via my Facebook and the UKNCDC Twitter.

I just could not help this premature announcement so I could put Amy Fulcher’s new title in print: Dr. Amy Fulcher will speak at the KNLA Summer Outing, Spetember 8, 2010, Ammon Nurseries, Burlington, KY on “A Horticulturist’s Perspective on Scale Pests of Woody Plants” - This presentation will cover some of the scale pests that are surfacing in nurseries and landscapes. Taken from a horticulturist’s perspective, the presentation will briefly outline each scale’s identification, lifecycle, potential to damage crops, impact on production and sales, integrated pest management-based control strategies, and how to stop scale pests before they get established at your business. Novel control strategies will also be discussed. Some of the scale pests that will be covered are Japanese maple scale, European fruit lecanium scale, calico scale, and oystershell scale.

From a reference UK diagnostian Paul Bachi found Half hours with insects by Alpheus Spring Packard dated 1877 the following appears which notes a species of apple borer which “is sometimes destructive to the apple, though the red maple seems to have been its original home.”

Dr. John Lindstrom, University of Arkansas, gave us some Amsonia plants to trial as part of the SERA-27 plant evaluations. He has named it Amsonia ‘Blue Bridges’. I have found this plant to be quite distinct with a large white terminal bloom with a bluish blush. Ours stand about 30 inches tall. Jon has also introduced Amsonia ‘Big Jon’ a particularly tall Amsonia that we are just starting to test; the bloom seems typical but it is still in a container. He gave us one plant, June cuttings rooted readily and we have enough plants for a landscape trial.

I was paging through Chlorophyll in His Veins by Bobby Ward to write a review and came across the description of xSinocalycalycanthus raulstonii ‘Hartlage Wine’ Theodore Klein Plant Award Winner for 2009.

Itea virginica ‘Theodore Klein’ seems to have a fatter shorter bloom that ‘Henry’s Garnet’. Checked Dirr, 2009, and he agrees. Also the foliage is nicer as I have observed and Dirr says “has shown the highest resistance to leaf spot and flea beetle in Zone 7.” Thanks to the late Thom Harmon for giving out plants at a LNA meeting so I am confident I have the right plant. (my first one from a commercial source looks identical to ‘Henry’s Garnet’)

2,4-D continues to be a common herbicide used in the early spring when ornamental plants are most readily damaged. Recently I was reading Kentucky Pest News, March 23, 2010,

http://www.ca.uky.edu/agcollege/plantpathology/extension/KPN%20Site%20Files/pdf/KPN1223.pdf

and found in SHADE TREES & ORNAMENTALS the following very interesting articles. The last one relates to a possible use of 2,4-D that could result in ornamental plant injury. Let’s hope the protecting of pasture clover limits 2,4-D use near nurseries.

-Pear Fire Blight: Maryblyt Predictions Can Aid in Disease Management

-Boxwood Leafminers

-Eastern Tent Caterpillars Feeding

-Buttercups in Grazed Pasture Fields - ……Buttercups are short-lived perennials or winter annuals that produce shiny yellow petals in the early spring. ….. If chemical control options are desired, most herbicides registered for use on grass pastures that contain 2,4-D, dicamba+2,4-D (eg. WeedMaster), aminopyralid+2,4-D (ForeFront), triclopyr (eg. Crossbow, PastureGard), or metsulfuron (eg. Cimarron) will effectively control this plant. However, legumes such as clovers interseeded with grass pastures can be severely injured or killed by these herbicide products. For optimum results apply an herbicide in the early spring (early March or April) before flowers are observed, when buttercup plants are still small and actively growing. For best herbicide activity wait until daytime air temperatures is greater than 55 F for two to three consecutive days.

I read in an e-mail from Mark Halcomb about Jim Robbins’, University of Arkansas, Newsletter called Arkansas Re-leaf Newsletter for the Commercial Green Industry. This edition can be found at http://www.aragriculture.org/News/ReLeaf/2010/march2010.pdf or you can go the archives http://www.aragriculture.org/News/ReLeaf/default.htm and look at any or all his newsletters.

So are we interested in the Ipad? While I have no experience with it other than picking one up and finding it heavy, the credit card apps for Iphone some use to offer credit card transactions (when infrequent use or bank costs have made it impossible) have been made available for the Ipad. This application may be handy for small businesses that want to provide for credit card purchases on site (nurseries being able to make transactions out with the customer instead of walking back to the office or at a small retail center or Farmer’s Market/Flea Market). Not to recommend any one over another when I do not use them but you might check what is possible by visiting https://squareup.com/ and https://squareup.com/features for a review see http://techcrunch.com/2009/12/01/jack-dorsey-square/n a quick search of ITunes shows other services are available.

Brian Jackson wrote an article for Greenhouse Product News Pine Tree Substrates for Greenhouse Crops. At the end of the article was a link to Brian’s site which led me to the NCSU Horticulture Substrates Lab publications site maintained by Bill Fonteno.

Bernheim Arboretum and Research Forest Vistors’ Center designers won EPA's Lifecycle Building Challenge which recognizes innovative green building ideas to reduce environmental and energy impacts of buildings and assists the building industry in reducing more than 88 million tons of building-related construction and demolition debris sent to landfills in the United States each year. The Professional Building category was won byKira Gould, William McDonough + Partners, Charlottesville, VA for their design of Bernheim Arboretum and Research Forest Visitors' Center. The visitors' center design roots the building firmly in its woodland context by blurring distinctions between the indoors and outdoors, and by incorporating the surrounding forest into the building's lifecycle analysis. Construction emphasized safe, closed material loops of biological nutrients, which break down to safely return to forest soil; and technical nutrients, which can be remanufactured into new objects. The mechanical connections and reconfigurable modules allow for building alterations. The project performs 51% better than the ASHRAE-compliant base case used to measure the greenhouse gas reduction. Kira Gould, William McDonough + Partners, Charlottesville, VA also won the Best Greenhouse Gas Reduction award sponsored by the American Institute of Architects Committee on the Environment (COTE) for Bernheim Arboretum and Research Forest Visitors' Centervisitor center. William McDonough is the co-author of Cradle to Cradle. Bernheim Facebook Page contained this information and lead to: http://www.epa.gov/greenbuilding/pubs/lbc3.html#winners

Aesculus species plants import banned. “The Animal and Plant Health Inspection Service (APHIS) is issuing a Federal Order (attached) to prohibit the importation from all countries, except Canada, of Aesculus spp. plants for planting (excluding seed) because they are hosts of Pseudomonas syringae pv. aesculi. To prevent the introduction and dissemination of this harmful plant pathogen into the United States, this Federal Order is effective beginning January 25, 2010.” http://www.sepdn.org/DesktopModules/ViewDocument.aspx?DocumentID=3231
