leaf bruising on Monstera Deliciosa

Quick answer

If your Monstera Deliciosa has leaf bruising, the most likely cause is: New, unfurling Monstera leaves are extremely tender and epiascidiate, making them highly susceptible to mechanical bruising from physical handling or tight ties. These bruises appear as dark brown or black patches that do not spread like disease but remain as permanent scars.

Start here:

  1. 1. Loosen or remove tight strings or ties near the top of the plant where new growth emerges.
  2. 2. Avoid touching or moving unfurling leaves until they have fully hardened off.
