The late summer and early fall is a delicate time for those deciduous leaves as they start their annual transformation. The bottom line is the leaves and trees want to avoid stress in order to bring on the best colors for the longest possible time. Stress would primarily include a late summer drought or a series of early season frosts. Other factors would include disease or insect infestation. So far this season, the stress level has been pretty low.
Despite the long, delightful stretches as of late, we’ve had generous and consistent summer rainfall. Even with all the nice weather this September, our precipitation total month-to-date still sits above the average. We’ve had a bunch of Frost Advisories recently but just a few light, scattered frosts so far. Ideally for the best colors (the deeper reds), nighttime temperatures should be consistently cool but not cold enough for frost or a freeze. Our temperatures the past few weeks have been right on that mark and our next seven days ahead show more of the same!
So shutter bugs get your cameras ready – there could be plenty of awe in our autumn this time around!
