yellow leaves on Philodendron Cordatum

Quick answer

If your Philodendron Cordatum has yellow leaves, the most likely cause is: Yellow leaves on heartleaf philodendron (Philodendron cordatum / Philodendron hederaceum) develop when the soil is kept too wet for too long, because persistently saturated substrate starves roots of oxygen and forces the plant to shed its older foliage. The houseplant reference explicitly names yellow leaves as the diagnostic sign of overwatering for this species.

Start here:

  1. 1. Stop watering and allow the surface of the soil to dry out between waterings, especially during winter when growth slows.
  2. 2. Check that the pot has drainage holes and that the mix is 50 percent regular potting soil mixed with 50 percent coco coir so excess water can escape.
