The park that I live next to has 3 apple trees (I'm in USA). These are not grocery store apples, they're small and riddle with bugs, this isn't an orchard.

When the apples are ripe, they'll get picked by kids and familes for a couple weeks. Nobody hordes them, nobody sees it as stealing, they're cool, and great for the community.

I'm just sad that they're getting old and about to die. There used to be 5 just a couple years ago. I think they may have planted a couple new saplings, but I'm not an arborist.

Fruit trees typically don't live as long as other trees, that's probably why parks and rec usually don't plant them. Having to replace an apple tree every 25 years as opposed to a Maple, Oak, Sycamore, Pine, Elm, Cedar every 100-200+ years, kinda an easy choice. With that said, I like it, and think it's worth. More parks should have a handful of them.
