edema on Philodendron

Quick answer

If your Philodendron has edema, the most likely cause is: Edema in Philodendron occurs when cells take up water faster than they can transpire it, causing cells to burst and creating corky, water-soaked patches. Triggered by irregular watering, sudden increases in humidity, or overwatering during low light periods when transpiration is reduced.

Start here:

  1. 1. Edema spots are permanent but do not harm plant health - leave affected leaves
  2. 2. Adjust watering to allow top 2-3 inches of soil to dry between waterings
