Ghost apples. Posted by Andrew Sietsema on Wednesday, February 6, 2019 Lots of fruits are out of season here in the northern hemisphere thanks to a rather harsh winter and a visit from our old friend, polar vortex. But recent freezing rain in Michigan led to the production of a rare psuedo-crop: the ghost apple.
The above photos come from Andrew Sietsema, a former horticulture student at Michigan State University, who told WOOD-TV that the apple-shaped ice shells formed when the frozen precipitation coated the apples.
When he pruned the trees, the shaking branches caused many of the icy apples to fall off, but in a few cases the entirety of the mushy, rotten apples just slipped through the bottom of the frozen shell. It's so cold out How long can your phone survive in a polar vortex?
