The past few years I have noticed something unusual. My fruit trees bloom twice. Once in early spring, when I am expecting it, and once in mid-summer when I am not. I noticed it first in our pear tree. With wilt and rust problems and a terribly cold rainy spring, I thought the tree just needed to try again. But that fall I noticed the large dogwood in the neighbour’s yard blooming. That seemed weird. Now I notice it in our healthy young apple trees as well. A bloom that comes on when the spring’s apples are between golf and tennis ball.
Do trees often bloom twice in the PNW or is this global warming at work? Is it really blooming twice or does our weather promote an extended blooming cycle like I read about in SoCal? Ideas?
