Largest Tree in Illinois

In the beauty pageant of trees, size is what matters most. Instead of evening gown, swimsuit and talent, the categories for consideration are circumference, total height and average crown spread. And the winner is.... a majestic sycamore tree on private property in Christian County that measures 31 feet around, 119 feet tall and has an average crown span of 134 feet. The first runner-up is a bald cypress tree in the Cache River State Natural Area in southern Illinois.

The base of this state champion sycamore tree (and largest tree in the state) is buried beneath 6-8 feet of sediment from floodwaters; Dick Little (left) and the late Ernie Williams (right) are essentially standing 6-8 feet above the base of the tree due to siltation from the adjacent river.

Statistics: 31 feet in circumference, 119 feet tall, 134 feet average crown spread, Christian County, IL. Nominated in the year 2000. Total Points = 525.

Sycamore, bald cypress, eastern cottonwood and some varieties of oak are the only serious contenders for the title of largest Illinois tree according to University of Illinois Extension forester Jay Hayek. Hayek developed an Illinois Extension Forestry website that manages the Illinois Big Tree Register. The site is located at http://web.extension.uiuc.edu/forestry/.

"I probably average one or two requests per day on the 'Ask a Forester' feature on the site," said Hayek. "People want to know how much their black walnut tree is worth, what kind of tree to plant in their backyard, and I get a lot of questions from landowners who need help managing their forest land."

Although Illinois ranks fifth in demand for wood, it ranks 32nd in the nation for production of wood. Hayek said the irony is that even though Illinois currently has around 100 sawmills, the state exports more than 25 percent of its sawlogs and 80 percent of veneer logs to primary manufacturers outside state boundaries. "Some of the exported logs are sawn into lumber and veneers and then imported back again," he said. "Illinois needs more primary and secondary forest products manufacturing facilities – it's a shame our economy can't benefit more from Illinois timber."

Converting marginal floodplain farmland to early successional floodplain forests is another one of Hayek's missions. "When a farmer reports crop loss due to flooding for three to five consecutive years, I encourage them to think about tree planting through state and federal conservation programs such as the Forestry Development Act and Conservation Reserve Program (CRP). It's a way for them to diversify the landscape and their portfolio - manage their land with natural buffers and make a reasonable return on their investment," said Hayek. In 2005, Illinois landowners received $20 million from selling timber, so there is money to be made.

"Illinois is famous for its corn and soybeans, but that same fertile agricultural soil is perfect for growing trees, too," said Hayek. "And, just about any tree planted in a good environment will grow rapidly."

The Illinois Extension Forestry website includes links to many government and educational sites about forestry. "Rather than reinventing the wheel, the site has links to the best sites for tree identification, forest management, selling timber, and other similar information," said Hayek. "This site provides the best education on forestry and unbiased information and links to a lot more."

Pubs Plus Website Enhanced

Farmers, home gardeners, and people needing information on money management or community development now have an enhanced outlet open 24 hours a day, seven days a week at a revised University of Illinois Extension website. PubsPlus can be found at: http://pubsplus.uiuc.edu .

"Pubs Plus is a source for books, CDs, and other educational materials prepared by experts in the College of Agricultural, Consumer and Environmental Sciences," explained Molly Bentsen, U of I Extension communications specialist. "It is a continuation of something Extension has been doing for years--offering fact-based information to people who can put it to work in their own homes, businesses, classrooms, and lives."

Bentsen said that recent revisions to the website have improved its search mechanisms, making it easier for users to get to the information they need. Items can be purchased online through the use of a credit card. Once, such publications were only available for purchase through check or money order and the transactions came by mail, phone or FAX (purchasers can still use all those methods in addition to ordering online).

"The educational materials available cover a wide range of topics," Bentsen noted. "For instance, agricultural producers have access to a variety of publications and products to help them in their enterprises. There are materials helpful to commercial horticulturists and a web-based record-keeping program for students with FFA projects. Teachers can find agriscience kits and other instructional resources for their classes from kindergarten through high school."

Materials are grouped under the following areas: Agriculture; Classroom Materials; Dollars and Sense; Environment; Family Matters; Gardening; Healthy Living; and Leadership and Community.

"Spanish products are being added as soon as they become available," Bentsen noted. "New and seasonal items and special promotions will be updated regularly. Visitors can also choose to receive e-mail alerts about new publications in their areas of interest."

New Apple Named 'Juliet' Resistant to Apple Scab

An apple a day may keep the doctor away, but what keeps the doctor away from the apple? And when that apple is infected with apple scab, the prognosis is grim for the entire tree.

Enter Juliet! -- an apple that showed so much potential that a French company created a cartoon character and advertising campaign to market it in Europe.

Juliet is a late-season apple that carries the Vf gene that provides a high level of resistance to apple scab disease triggered by a fungal pathogen, Venturia inaequalis. Juliet has also shown resistance to powdery mildew and fire blight and reduced susceptibility to another fungal pathogen that causes cedar apple rust.

U of I plant geneticist Schuyler Korban collaborated with researchers at Purdue and Rutgers universities to develop Juliet. "Because the original seedling was selected here, U of I holds the licensing rights to the variety," said Korban.

Juliet is about 85 percent red with some green undercolor. It has less sugar than the Fuji but enough balance of sugar and acid to be considered full-flavored. It also stays on the tree for a longer time without dropping off and can be kept in cold storage for six to seven months.

But its resistance to apple scab is what makes it most attractive to growers. "Apple scab is a problem around the world, and unfortunately the conditions in Illinois are perfect for apple scab," said Korban. "Washington State has lower heat and humidity as in Illinois, but apple scab is still a problem worldwide."

Korban said that growers typically have to spray 12 to 15 times per growing season. They mix a cocktail of pesticides and insecticides that isn't always the same, but the fungicide(s) to prevent apple scab is in every application.

"The resistance to scab makes Juliet environmentally a better choice because it requires less chemical sprays than other apple trees," said Korban. "And it ripens two weeks after Red Delicious, making it more marketable as a late-season apple."

A nursery in France called Escande realized Juliet's potential and acquired the rights to grow and market the variety in Europe. They are hoping to find apple growers in the United States that would be willing to abide by their rules for growing this apple. Because Juliet is being marketed as an organic apple, it would need to be grown by certified organic growers.

The marketing firm created a cartoon character whose likeness appears on brochures, packaging and tiny apple stickers. "You can even become a 'friend of Juliet' on the website at www.pomme-juliet.com," said Korban.

Korban said that the fungus that causes apple scab is transmitted via infected leaves, even those left on the ground over the winter. The disease affects blossoms, leaves, and fruits, eventually killing the tree. The infected fruit can sometimes be used in processed products that include apples but the appearance renders it unsellable for the fresh market.

Juliet is the 15th apple cultivar developed by the cooperative breeding program between the University of Illinois, Purdue University, and Rutgers University.

Amazing Tree

This amazing tree picture were sent to the State Horticulture Team from Chris Doll, retired Horticulture Educator. The following is a note from Chris.

This tree was grown in Santa Cruz California, the year I don't know, but the man that grew them never told any one how he did it. In 1999 the owner of Nob Hill foods in Gilroy, California moved them to his park in Gilroy and they are doing well.

Yale University Going Green

At World Economic Forum, mere talk isn't enough. "We cannot wait for our governments to act," Yale President Richard Levin told delegates on Thursday. "Large organizations with the power to act independently should take matters into their own hands and begin to reduce greenhouse-gas emissions now."

Levin has made good on his own call, implementing a program that he hopes will make Yale the greenest university in the United States.

Part of that program is the Yale Sustainable Food Project. Yale students, faculty, and staff, President Richard Levin, and Alice Waters founded the Yale Sustainable Food Project in 2001. The Project seeks to nourish a culture in which the pleasures of growing, cooking, and sharing food are integral to each student's experience at Yale.

The Project was established with the understanding that many of the world's most important questions regarding health, culture, the environment, and the global economy are deeply connected to what we eat and how it is produced. Food cannot stand apart from agriculture, the environment, or the communities where it is grown. The Project's work underscores Yale's ability to advance local, national, and international dialogue on these global issues.

Chicagoans Can Earn U of I Horticulture Degree on their Own Turf

Like many college students, Matt Dingledein didn't follow a straight path academically to a career. "I started my undergraduate career as a music performance major at DePaul University," said. "Then I went on to complete an AAS in Ornamental Horticulture at the College of DuPage." After getting his associate's degree, Dingledein went into business for himself as owner and operator of a small landscape contracting business in Naperville.

Dingledein wanted to continue studying and work toward a bachelor's degree in horticulture, but moving or commuting to the University of Illinois at Urbana-Champaign was out of the question. "My being away would have made maintaining my client base very difficult and the investment required was also a large deciding factor," said Dingledein.

Dingledein is now taking horticulture classes in a new U of I degree program being offered in the Chicago area.

In fall 2006, the University of Illinois began partnering with Chicago area community and city colleges to offer a bachelors degree in horticulture. Students who have completed an associate degree such as Dingledein can complete their final two years of coursework taught by resident faculty in the Chicago area or faculty from campus and earn a bachelors degree from U of I at Urbana-Champaign -- without relocating.

Most of the courses are offered at the Multi-University Center in Oak Brook, Morton Arboretum in Lisle and the Chicago Botanical Garden. In the future, classes will meet at the University Center at Lake County and satellite locations in the collar counties such as Chicago's Center for Green Technology.

The program is particularly helpful to non-traditional students -- typically working professionals who are managing school, work and family. The University, community, and city colleges hope this will provide an opportunity for students to pursue their horticulture degree without "pulling up roots." The majority of courses are offered in the evening and weekends in order to accommodate student workday schedules. Some courses may be offered on-line or via video conferencing when appropriate. But, because the program results in a diploma from the U of I at Urbana-Champaign, the curriculum requirements and course quality will be the same as if the courses had been taken at the main campus.

"Jobs in the green industry are abundant," said Wesley M. Jarrell, head of the Department of Natural Resources and Environmental Sciences (NRES) in the College of Agricultural, Consumer and Environmental Sciences on the Urbana-Champaign campus. "A 2003 Green Industry survey conducted by NRES cites a $4.72 billion dollar industry employing over 15,000 people in Illinois, so it's important to the state."

The program will be directed by landscape architect Greg Pierceall, who has 30 years of experience with environmental education and landscape design. "I got an undergraduate degree in horticulture from SIU and a master's in landscape architecture from U of I, but I'm also a product of the junior college program, having started my education at Prairie State College in Chicago Heights -- so I've come full circle," said Pierceall. "He said that non-degree seeking students can also take courses in the program, purely for enrichment; if they are admitted to the degree program later, they can petition to count those courses.

For information, contact Piper Hodson (800-252-1360, ext 45761; nres@uiuc.edu) or visit www.nres.uiuc.edu.

Green Chicago Mini-Grants

Each year, in the early spring months, GreenNet administers the Green Chicago Mini-Grants program. The program, sponsored by the Prince Charitable Trusts assists urban gardeners working in publicly accessible green spaces with grants that fund gardening materials, supplies, and activities. The mini-grants are intended to fund a small project or a special part of a larger project, with awarded funds ranging from $100 to $1,000. Grant money is used to buy seeds, plants or soil, lumber or mulch, compost bins, buckets, nails, schoolbooks related to school gardening, even a garden festival for the community.

To qualify for a GreenNet Green Chicago Mini-Grant, the garden project must be in Chicago in a schoolyard or community garden, or other community greening project. The work and garden area should promote ecological issues, such as a pesticide or chemical-free food garden, plantings that showcase Illinois prairie or woodland plants for birds, butterflies, dragonflies, etc., a composting system that recycles waste and gives nutrients back to the soil, wooden structures free from dangerous chemical preservatives, or a garden that converts lawn to no-mow perennials, shrubs or trees. Applicants must also own or have permission to use the land, and must represent a group such as a block club, garden club, faith-based group, school or other youth group. Finally, funding priority is given to garden groups with an existing (rather than proposed) garden or greening project.

Mini-grants applications will be mailed out to Chicago school and community groups in mid-January with an application deadline of mid-March. Groups are notified of their grant status by early April and funds are distributed near the end of April. Access an application online. To find out more about Green Net's Green Chicago Mini-Grants Program, or to be included on the program mailing list, please call Sherry Legare at 312/863-6266, or e-mail slegare@openlands.org.

Remembering Brian Williquette

Brian Williquette, a friend and former colleague passed away suddenly last Friday. Brian died of a heart attack leaving his wife and three children. Brian was only 50 years old.

I knew Brian for 24 years. I actually interviewed for his Urban Gardening Educator position with Extension in 1984 after he had been promoted to the position of Urban Gardening Program Coordinator. After leaving Extension, Brian worked for the Chicago Park District, Bartlett Trees and Brickman's Landscaping. He was highly respected in Chicago's horticulture community.

I will remember Brian for his work ethic and his tremendous knowledge of horticulture. We used to kiddingly call him "The Brain" Williquette. The past few years he has taught a number of our Chicago Master Gardener classes. He will be missed.

Periodical Cicadas are Coming!

The cicadas are coming! The 17-year periodical cicadas will be appearing in the Chicago area in spring 2007. Their last appearance was in 1990.

  • Full-grown cicada nymphs are brown, humpbacked and about three-quarters inch long.
  • They commonly construct soil chimneys that extend from the ground up to three inches high and are about one-half inch in diameter.
  • Within a few days, the nymphs break through the top of the chimneys or soil surface to crawl up trees, shrubs and other upright objects where they molt into adults.
  • Adult periodical cicadas are about one and one-quarter inch long black insects with red eyes and orange-veined, clear wings.
  • Males produce a high-pitched wavering song that sounds like a trill when many are singing together. They sing primarily during the sunny part of the day to attract females to them for mating.
  • The males and the singing die after a couple of weeks, while females remain alive for two to four weeks longer to lay eggs.
  • Eggs are inserted into tree and shrub stems that are up to two inches in diameter. Heavy egg laying will cause twigs to break, resulting in dead leaves at the end of branches.
  • Control is directed at preventing egg-laying damage, as adult feeding is insignificant.
  • Although pyrethroids and carbaryl (Sevin) will kill large numbers of adults, treated plants commonly experience about as much injury as untreated plants in landscapes. Mature trees and shrubs usually experience only minor damage.
