Short Hort Notes

*Recent Problems:
--Trees outgrowing their space: Urban trees are often planted too close together and are expected to live forever (!). They don't though, and when old, mature trees begin to decline, it's often difficult to tell if it's the end of their usable life or if something else is happening. In small yards, cottonwoods and spruces (and other large trees at lower elevations) can quickly outgrow the area allotted to them. They then must compete with other vegetation for water, nutrients, and often light too. This stresses the trees, making them more susceptible to insect and disease problems. Usually it's time for the trees to come down, although that's a tough decision to make.
--Odd-shaped tomatoes: This probably the result of a combination of genetics, water relations, temperature, and nutrition. Though the shapes were atypical, the fruits ripened normally.
--Needle drop on conifers: Pines are dropping needles again, just like they do every fall. Normal needle drop occurs in the fall, toward the inside of the tree. The extent depends almost entirely on the type of pine - some lose 1/3 of their needles each year (ponderosa, Scotch) while others lose only about 1/7. It may look like the trees are toast, but usually that's not the case.
--What variety of pear tree do I have in my back yard? It's virtually impossible to tell. There are hundreds of varieties out there and it is not feasible to determine which one it might be. The same goes for apples.
 
*Next Horticulture Train-the-Trainer: We are scheduling our third Horticulture Train-the-Trainer session for Tuesday afternoon and Wednesday morning, November 28 and 29, here on campus. Two of the topics for this session include Vegetables and Vegetative Plant Propagation (cuttings, etc.). We are looking into two others. Registration information will be sent out in the next week or two.
 
*Update on Help for Choosing Trees Web Site: The Northern Trees site (http://orb.at.ufl.edu/TREES/index.htmlmentioned in the last issue of Short Hort Notes is useful for some things, but not searching for suitable trees for the western United States. It is geared toward the eastern half of the country. (Thanks Rik!)
 
*Abstract from Article in HortTechnology: 'The Economic Impact of the Green Industry in the United States' by Charles R. Hall (University of Tennessee), Alan W. Hodges (University of Florida - Gainesville), and John J. Haydu (University of Florida - Apopka), HortTechnology, 16(2):345-353, April - June 2006.
"The United States environmental horticulture industry, also known as the Green Industry, is comprised of wholesale nursery and sod growers; landscape architects, designers/builders, contractors, and maintenance firms; retail garden centers, home centers, and mass merchandisers with lawn and garden departments; and marketing intermediaries such as brokers and horticultural distribution centers (re-wholesalers). Environmental horticulture is one of the fastest growing segments of the nation's agricultural economy. In spite of the magnitude and recent growth in the Green Industry, there is surprisingly little information regarding its economic impact. Thus, the objective of this study was to estimate the economic impacts of the Green Industry at the national level. Economic impacts for the U.S. Green Industry in 2002 were estimated at $147.8 billion in output, 1,964,339 jobs, $95.1 billion in value added, $64.3 billion in labor income, and $6.9 billion in indirect business taxes, with these values expressed in 2004 dollars. In addition, this study evaluated the value and role of urban forest trees (woody ornamental trees); the total output of tree production and care services was valued at $14.55 billion, which translated into $21.02 billion in total output impacts, 259,224 jobs, and $14.12 billion in value added."  
    So where does Wyoming fit in the big picture? Our output impact for all sectors of horticulture (production/manufacturing, horticultural services, and trade) was $174 million. Number of jobs? 2,581 for all sectors. Value added impacts? Another $109 million. Not bad for half a million people!
 
*In the Panter Back Yard: The growing season is pretty much over with. When you can barely see the grass because the back yard is covered with yellow cottonwood leaves, you know it's autumn! We pulled out the tomato plants a week ago - but not before removing all the fruit we possibly could. The raspberries are still ripening, however, despite the cold temperatures. And the broccoli is still producing. There are many plants still blooming outside: asters, rudbeckia, coneflower, Russian sage, plus the annuals in containers that we move in and out of the garage depending on weather. Impatiens and basil in flower beds bit the dust several weeks ago, with the first hint of freezing temperatures. Most of the cottonwoods in the neighborhood are at least yellow/gold and many are already bare of leaves. The Montmorency cherry in the back yard is still green! Tough tree. We (more accurately Mark) sunk all the small containerized woody plants in the ground on the east side of the garage for the winter. They are buried pot deep in the soil. This way, they are protected from temperature swings as the soil moderates these fluctuations. They also don't blow over in the wind and they're easier to keep moist through the winter too.
    Inside, the orchids are still in bloom - it seems to be constant. We brought the containerized geraniums inside a couple of weeks ago, so they can drop their flowers all over the floor in the den.....they are sooooo messy.
