Fall Leaf Color Report for Week of September 16, 2013

The forecast for this week is, in a nutshell, the same as last week: Green! Trees in the High Country still have most of their leaves, and there is isn't much to report right now. Yellow buckeyes are about the only tree species to show a significant change: most have started losing their leaves (remember, these trees are early to leaf out, and early to lose them in the fall – the botanical equivalent of early to bed, early to rise!). However, they also get a leaf fungal disease, so their leaves do not provide much color. Dogwoods and burning bushes are coming along and increasing in color each week, and the occasional sugar or red maple have some orange/red leaves. Otherwise, as I stated above, the word is still GREEN.

The long-range forecast for the southeastern portion of the country, including the southern Appalachians, is for above-normal amounts of precipitation. That doesn't bode well for great fall leaf color, because sunny and cool conditions are what lead to good fall leaf color. But so far the weather has been near perfect for good fall color, so let's hope that we don't get too much rain in the next few weeks. If not, we should have a great fall color season this year!

As I was driving back from a short visit to the coast on Sunday, I was thinking of how green the mountains looked as I headed up US 421 into Watauga County. That started me thinking of all things green: How Green Was My Valley, the Grass is Always Greener on the Other Side of the Fence, and It Isn't Easy Being Green (https://www.youtube.com/watch?v=51BQfPeSK8k, with Kermit the Frog). What phrases can you think of that relate to "green"?

Have a great week! Don't forget, you can check out essays on the science of fall color at my other fall color site, as well as a list of what colors each tree turns: http://biology.appstate.edu/fall-colors
