The stairs leading to the door of a building in Borough Park, Brooklyn, were constructed on an angle to accommodate a fruit tree, a custom among Orthodox Jews.
Sheya Wieder owned a small old house on a large lot in Borough Park, Brooklyn, until about six years ago, he said, when he decided it was time to knock it down and build an upgrade. He was all set to go when it occurred to him that the big, shady tree, standing tall and proud right where his new stoop would go, might cause a problem. He took a branch to Brooklyn Botanic Garden, where he was told it was a mulberry tree.
