In Pixar’s Elemental , the “pruning” joke is basically a sneaky innuendo disguised as gardening.

What actually happens in the scene

  • Ember and Wade look through a window and see two Earth people who look like apple trees.
  • The Earth couple is picking each other’s fruit in a way that clearly looks intimate or private, not like normal gardening.
  • When they realize they’ve been seen, they get flustered and quickly claim they’re “just pruning.”

So on the surface it’s a harmless gardening line, but visually it’s staged like they’ve been caught in the middle of something romantic or sexual.

What the “pruning” joke means

  • For tree-like Earth people, “picking each other’s fruit” is treated like a stand‑in for physical intimacy, kind of like humans being caught making out or more.
  • Saying they’re “just pruning” is a cover story: pruning is a normal, respectable tree-care task, so it’s the PG excuse for what looks like “hanky‑panky time.”
  • Later in the movie, there’s another line about whether there will be any “pruning” on a date, reinforcing that the word is being used as a playful code for romantic activity.

In other words, the pruning joke is Pixar’s way of slipping in a cheeky adult- style gag that still passes as kid-friendly because it’s all framed through tree people and gardening language. TL;DR: The “pruning” joke is a visual and verbal innuendo: the tree couple is basically caught being intimate, and “we’re just pruning” is their embarrassed, family‑friendly excuse.
