Improving Bougainvillea Cutting Success: Proper Rooting Hormone Use, Watering, and Light

Fix the Protocol

30+ failed cuttings indicate systemic errors. Key corrections:

1. Leaves: Leave 3–4 leaves; cut others at node.
2. Soil: Wet mix thoroughly before inserting cuttings.
3. Hormone: Dip cut end; tap excess. Poke hole with pencil; firm soil around.
4. Humidity dome: Zip-top bag is OK.
5. Watering: No daily misting. Water by weight: soak, drain, wait until pot feels light.
6. Light: Bright indirect only. No direct sun (except morning).
7. Heat mat: OK if not too hot (70–75 °F).

Why It Works

Constant moisture in the bag + daily misting = rot. Bougainvillea roots need oxygen—let the medium dry slightly between waterings.
