In any normal year, north Texas Autumn
leaves develop in late October to mid-November. Last Fall 2006, the
Autumn colors did not develop correctly.
One tree which has always had
deeply colored red and orange leaves in the Fall, failed to change
colors last Autumn. Nor did it drop the leaves. During Mid-winter, the leaves eventually turned brown, but
still failed to fall from the tree. Only when the trees began to bud in early February,
did the old leaves finally drop off. While this was odd behavior for
that particular tree, by itself, it would not have been substantial
reason to suspect the axis was abnormal
In May, 2007, that same tree started
changing to Autumn colors. In June, several trees started changing to
Fall colors. This was another indication that something was wrong. The
trees had gone into photoprotective modes due to the abnormality of the
sunlight they received during these months. This is a significant sign
that the position of the sun has changed. |
