MAllen - We had a couple maple trees that looked like your pictures. After looking at a piece of bark from our trees, our local nursery guy said our problem was caused by bugs under the bark. He gave us a concentrated spray, which we applied from the base of the tree to as high as we could reach. I'm remembering we also treated the soil with something else, but it was years ago, so I don't remember the details, other than we put pellets into a root feeder and shot the chemical into the ground.
Eval is finished! I won't know the results until next week, but it seemed okay. Students asked about the hose (siphon for the duck pond - cleaned with bleach before I brought it to school) so we discussed siphons for a few mintues. That led to complaints about the high price of gasoline, so I had to redirect [siphons are not to be used to remove gas from your neighbor's car]. Anyway, I think a few students had an "Ah haaaah!" moment when I turned the hose and rope into a giant coaster. Wrap 6, figure 8 through the closest coil section, wrap 6, and so on. I think we're going to end up with some really neat baskets this year.
First Lunch - Time to grab a bite and grade some papers. Have a great day, everyone.
