I am in the "piney woods" temperate rainforest of east Texas. Three months ago I had a large oak (18 inch diameter, 70 feet tall) removed. It was about 4 feet south from the patio and 12 feet from the house. There is a large shortleaf pine (24 inch diameter, 100 feet tall) six feet south of where the oak had been, so 10 feet from the patio and 18 feet from the house. (Yes, I made a big mistake saving too many trees when the house was built.)
I just noticed the pine has curved to the north, toward the house. The trunk leans a little to the south, but now I notice it curves about 15 feet to the north, starting at about 50 feet up. I did not notice it three months ago when I looked up to watch them cut out the top of the oak. These southern pines are basically straight power poles, so a curved one looks all the more peculiar. How could this happen in a few months? It is curving away from the sun.
