Shaking Shailos

Shimshon picks up his lulav and esrog on the first day of Sukkos. However, the pitum is facing the floor.
Boruch: Shimshon, your esrog is upside down! The Gemara says (Sukkah 42a) that if one’s arba minim are upside down, he does not fulfill the mitzvos.
Shimshon: Well, the Gemara says that one is supposed to hold the arba minim in the same direction they grow in (ibid 45b). When the esrog grows on the tree, the pitum faces the ground. So I am indeed holding the esrog the way it grows.
Boruch: Well, technically, you’re right. However, when the esrog starts growing, the pitum faces the sky. It’s only when the esrog becomes heavy, that the pitum faces the ground. So to fulfill the dictum of Chazal, you should hold the pitum facing the ceiling.
Shimshon: You’re right, too. However, I did not recite a bracha yet. I want to say the bracha before I fulfill the mitzvos of Arba Minim. If I held the arba minim correctly, I’ll be forced to say the bracha after I already fulfilled the mitzvah. So I am temporarily holding the esrog upside down. After I recite the appropriate brachos, I’ll turn the esrog right side up. (Tosfos 39a D”H Oveir)
