Curse Fruit Tree (3.5e Spell)

''The next day as they were leaving Bethany, Jesus was hungry. Seeing in the distance a fig tree in leaf, he went to find out if it had any fruit. When he reached it, he found nothing but leaves, because it was not the season for figs. Then he said to the tree, “May no one ever eat fruit from you again.” And his disciples heard him say it.'' - Mark 11:12-14

For whatever reason, you direct the divine wrath of your all-powerful (and apparently all-knowing and all-loving) god to make a fruit tree never bear fruit again. After the spell is cast, the tree will never be able to produce fruit. Because god hates figs.

Note
If you actually want to use this spell in your game, it would be better to make it a 1st level ritual with a short casting time.
