yellow leaves on Philodendron Sellum
Quick answer
If your Philodendron Sellum has yellow leaves, the most likely cause is: Yellow leaves on Philodendron sellum (syn. Philodendron bipinnatifidum, horsehead philodendron) are most often caused by overwatering, especially when the yellowing leaves are also wilting; prolonged saturated compost then allows the fungal root-rot infection to take hold, producing soft dark roots that can no longer supply the foliage. If watering has been correct, the yellowing can also indicate that an under-fed plant is drawing on limited nutrient reserves.
Start here:
- 1. Reduce watering immediately and only water again once the top of the compost has dried out a little, then feed once a month in spring and summer to restore nutrient supply.
- 2. Unpot the plant, inspect the roots, and cut away any soft, dark, rotten roots with a clean knife, leaving only firm white roots before treating with a fungicide and repotting into a disinfected pot with fresh compost.
