A folk rock ballad,[2] "Garden Song" was produced by Bridgers herself alongside Tony Berg and Ethan Gruska.

[1] The song features a "wave of shimmery synths" and "delicate, crushing vocals", with its lyrics depicting "a scene from a fairytale, one that includes a house resting on a hill with thousands of roses (and probably a few ghosts)".

[6] The songwriting was stated to be "dreamlike and mundane", containing the lyrics: "The doctor put her hands over my liver / She told me my resentment's getting smaller".

[7] It depicts Bridgers "kicking back in her bedroom, ripping on a bong and hanging out with fuzzy creatures", with an appearance by comedian Tig Notaro.

[9] Deeming the song "an understated rumination on lost time and complicated nostalgia", Quinn Moreland of Pitchfork praised its "slight arrangement" and Bridgers' "humor and storytelling idiosyncrasies".
