I noticed a few days ago...we have one maple tree starting to change colors. I bet it has something to do with the near drought situation.
I've been watching the Maples. I've identified several that probably won't last but a couple more years.
The little town North of us where I do business has lost several Maples in the past 10 years. From watching them, I've sort of got a system down to determine which trees will not last much longer.
Trees that 'turn' much earlier than the other Maples don't have many years left, according to my theory.
There are 2 more trees in this little town that have turned early this year. My guess is they'll be dead as a door nail within 5 years.
The Joseph's Coat in my flower bed is starting to turn. I'm guessing it has to do with the length of daylight. I'm going to try to bring some in and winter it over. It's quite difficult to find in the garden centers and would make a lovely display with the Mums and asters if you had enough of it.
