root rot on Philodendron White Knight
Quick answer
If your Philodendron White Knight has root rot, the most likely cause is: Philodendrons collapse when their root zone stays saturated; the philodendron section in Kramer's Philodendrons lists collapse of the plant and root rot together as the direct outcome of poor drainage, with a sour, poorly drained substrate also blamed for the related symptom of slow growth, all of which apply to the White Knight cultivar grown in dense, moisture-retentive potting mix.
Start here:
- 1. Remove the plant from its pot and cut away any brown, mushy, or hollow roots with sterilized pruners, then dust the healthy white roots lightly before repotting.
- 2. Repot into a fresh, fast-draining aroid mix with plenty of bark and perlite, and confirm the decorative pot has drainage holes so excess water can escape after each watering.
