 Barron County Master Gardeners Training Scheduled for this Fall

Being a master gardener is about becoming a Volunteer with the University of Wisconsin-Extension to help educate the public about gardening and natural resources.  Level 1 Master Gardener Volunteer Training is being offered in Barron County from September 5 through November 14.  Classes will be held at the UW-Barron county Campus in Rice Lake on Tuesday evenings.  The fee for the course is $125 per person and covers all course materials and supplies.  Class size is limited so pre-registration is required by Wednesday, August 23 by contacting the Barron County UW-Extension office at 715-537-6250 or tim.jergenson@ces.uwex.edu.

Each training session will be about 2 hours long and is intended to increase your knowledge base of horticulture topics and provide methods on how to find reliable information when posed a horticulture question.  Sessions will be a mixture of interactive training, discussions, guest speakers and hands-on activities and skills development.  Certification requires attending 12 or the 13 sessions, volunteering 24 hours of relevant community service, a completed background check and signed volunteer agreement and passing of a final exam.

Winter Damage to Evergreens

The damage to evergreens that we are seeing this spring is “winter kill or “winter burn.”  The brown spots or tips of evergreens are die-back caused by a combination of things.  Winter burn results from water loss in plants during winter.  During the growing season, water is absorbed and pumped from soil into the roots of plants.  This lost water is quickly replaced as roots continue to absorb and pump water from soil into plants.  Because evergreen woody plants retain their foliage, transpiration and loss of water continue during winter.   Roots in frozen soil have no ability to replace this water and as a result, winter burn occurs as leaves desiccate, die and turn brown.
