November’s Full Beaver Moon falls on November 30th this year! It is called the "Beaver Moon" because his is the time of year when beavers begin to take shelter in their lodges, having laid up sufficient stores of food for the long winter ahead.
Discarding Holiday Wreaths? Beware of Boxwood Blight
By Lina Rodriguez Salamanca, Plant and Insect Diagnostic Clinic, Tom Creswell and Gail Ruhl from the Purdue Plant and Pest Diagnostic Lab (PPDL) and Brian Hudelson from the Plant Disease Diagnostics Clinic University of Wisconsin-Madison
Pathogens that cause plant diseases can move in mysterious ways. Last year, holiday wreaths that contained boxwood twigs and leaves, as part of the decorations, were contaminated with the pathogen that causes boxwood blight and inadvertently sold to consumers.
Boxwoods in the Midwest and Great Plains can suffer from multiple diseases and abiotic (disorders) problems. Often, due to low temperatures and open winters with little snow, boxwoods in the landscape become prone to injury and other root and foliar diseases.
This holiday season, we invite you to inspect Christmas wreaths for symptoms of diseases and signs (i.e., evidence) of disease-causing organisms before you buy them. Once you get your wreath home, avoid hanging it near boxwood shrubs or pachysandra (spurge) in your yard. The boxwood blight fungus can easily move from contaminated wreaths to healthy plants.
If you suspect your holiday wreath is contaminated with Boxwood blight get in touch with your local plant clinic. In Iowa, contact us the Plant and Insect Diagnostic Clinic. Visit the National Plant diagnostic network Clinic at the site NPDN, scroll to the map and click on your state.
Finally and most importantly, when disposing of your holiday wreaths, burn them (if your locality allows) or place them in plastic bags and put them in the trash. DO NOT compost your wreaths.
For more information on boxwood blight, please see the article “Boxwood Lovers: Beware of the Blight”, publication BP-203-W “Boxwood Blight or the Virginia Tech Boxwood Blight Task Force site. To learn more about last year’s problem with boxwood blight in wreaths, see the Purdue PPDL article “Boxwood Blight on Holiday Greenery” and this holiday season recent report in Michigan "Have a closer look at your boxwood wreaths this holiday season"
