June 2010     Volume 1     No. 2

Many exciting things are happening in the MG program. In fact, President Obama and Ag Secretary Vilsack recently visited a Henry County MG on her farm. Iowa MGs are teaming up with 4-Hers to grow food. A new Summer Webinar Series (see below) is planned. At the national level, a new MG blog was just launched with contributions from state MG program coordinators - watch for a contribution from Iowa in mid-July. Finally, please encourage Extension staff to post all of the exciting upcoming MG activities in your county on the ISU Extension Calendar.
MG Highlight of the Month

Patricia Stutzman
Patricia Stutzman, MG in West Pottawattamie County since 2008, has volunteered many hours at Lauritzen Gardens, Omaha's Botanical Center. Jane Diesen, volunteer coordinator at the Lauritzen Gardens says, "Patricia Stutzman truly is a rock to our greenhouse staff and volunteer crew and comes with so much knowledge." Patricia has nearly 2000 volunteer hours on record at Lauritzen Gardens since beginning in 2005 as a volunteer.
Diesen says most weekdays you will find Lauritzen Garden volunteers along with MG volunteers helping in the greenhouses. "We at Lauritzen Gardens support the Master Gardener programs both in Iowa and Nebraska; going through the training is like taking a year's worth of university studies" states Diesen. During the Spring into Spring festival, Lauritzen Gardens has an Ask the Master Gardener Table. We appreciate all MGs such as Patricia Stutzman and their many hours of service. -Rachel Summy, ISU Extension in West Pottawattamie County

Hosta Awareness
HVX-infected hosta (left) vs. healthy (right)
ISU May Bar
While Hosta virus X (HVX) may sound like a nasty computer virus, it's actually a virus of the most beloved shade plant of gardeners - the hosta. HVX-infected plants can be symptom free, or the leaves can appear twisted, puckered, have unusual color variations and spotting. Some hosta aficionados may actually like these unusual looking plants, but you don't want this disease in your garden. HVX is transmitted when plant sap from infected plants are mingled with sap from healthy plants. Therefore, gardeners must take special care when dividing hostas. See ISU publications SUL 14 and PM 1594 for more information or contact the ISU Plant and Insect Diagnostic Clinic for help with diagnosis. -Robin Pruisner, State Entomologist, IDALS
Seeking Potential Trees for Thousand Cankers Survey
USDA Forest Service specialists, in cooperation with state agency specialists, plan to conduct a targeted survey of black walnut and pecan trees with reported occurrence of trees exhibiting unexplained dieback in the their crowns. Samples will be collected from >2 in. diameter branches from affected trees. Insects and fungi associated with the symptomatic branches will be identified. The geographic focus of the survey will be states on the western edge of the range of black walnut (Juglans nigra), including Iowa. If you know of a plantation, stand (particularly in a riparian area), urban and community forest, or roadway setting with trees meeting these criteria and think they would be good candidate trees for the survey, would you consider supplying the information to us? Please complete the online form. Your interest and cooperation is much appreciated! -Jill R. Johnson, US Forest Service
