"Ron, If you put an appropriate amount of spawn in the log and the logs are fresh (not colonized by any other decay organism) the shiitake should be able to colonize the log, more or less, fully. There is the potential for other decay organisms…"

Tracking Pests with Growing Degree Days

Posted on May 3, 2012 at 4:11pm 0 Comments

Insects rely on warm temperatures to grow, and thus their emergence and life cycle progression can be tracked by tracking the "heating units" that accumulate each day. This is referred to as growing degree days.

Growing degree days (GDD) are calculated by average the high and low temperature for the day and subtracting 50 (base 50). The positive remainder is added to the cumulative total of GDD. For more information on GDD and how to calculate the go to:…

There are lots of things you can do to celebrate Arbor Day. Traditionally we plant a tree, have the Mayor read a proclamation, and get our picture taken by Frank with the paper. But, there are other things you can do. If you're, like me, concerned about the Emerald Ash Borer, or other forest health issue, you can use the day to bring some attention to it.

Here are some ideas:

  1. Take part in an Ash Tagging event. Contact your local…

Pest ID Resources

Posted on March 21, 2012 at 3:47pm 1 Comment

During the "How Pests Pester your Trees" webinar today, I was asked what references I use. I use a lot. Here is a short list. Some of these are for keying out, some would be used for verification of ID. Most of these do not include management recommendations; that's a different list!

Books I use (and I use mostly books for initial ID):
