A Fruity Matter

There is a well-known prohibition against cutting down fruit trees needlessly. Indeed, many non-Jewish gardeners are even aware of this. Some non-Jewish gardeners preemptively ask the religious owners to buy the fruit trees from them so that they may be cut down. Still, some individuals would rather suffer with the mess of a fruit tree than have it cut down. What is the basis for the stringency?
Rav said concerning a palm tree that still produces fruit in the amount of a kav that it is prohibited to cut it down due to the prohibition of: “When you shall besiege a city…you shall not destroy the trees” (Deuteronomy 20:19). (See Bava Kama 91b.)
Yet, there is a firm basis to permit cutting down a fruit tree in some situations. Ravina said, “If the lumber was greater in monetary value than its fruits, it is permitted to chop it down, and this does not violate the prohibition against destroying a tree.” Indeed, the Gemara even quotes a beraisa that supports Ravina.
The Gemara further cites two stories where fruit trees were cut down.
