yellow leaves on Silver Sword Philodendron
Quick answer
If your Silver Sword Philodendron has yellow leaves, the most likely cause is: Yellowing foliage on a silver sword philodendron (Philodendron hastatum) is a symptom of the same cultural stresses that affect most vining philodendrons in the home, namely heat that is too high, humidity that is too low, soil that is being kept too dry or too wet, or a combination of those issues; prolonged dryness around the root ball in particular will trigger chlorosis on the arrow-shaped leaves this species is grown for.
Start here:
- 1. Move the plant to a spot with average home humidity and away from heat registers or drafts, then keep the potting mix evenly moist (moist to the touch) by watering roughly twice a week in spring, summer, and fall, dropping to once a week in winter for pots up to twelve inches.
- 2. If leaves are still yellowing after watering has been corrected, repot into fresh, porous, well-draining soil so the root zone is not staying soggy, and mist the foliage weekly with tepid water to lift humidity around the leaves.
