How to Revive a Dying Bonsai Tree: A Comprehensive Rescue Guide

I rescued a neglected ficus bonsai from a garage sale where it had dropped most of its leaves. Six weeks of bright light, trimmed dead branches, and steady water later, it pushed out fresh growth like nothing happened.

Is Your Tree Still Alive? The Scratch Test

Before you panic, check whether there’s still a fight in it.

Perform the Scratch Test

  • Scratch the bark gently with your fingernail
  • Look for green tissue underneath
  • Green = hope! Brown and dry = trouble
