Troubleshooting
Spiritus Sancti problems — and how to fix them
Spiritus Sancti (Philodendron spiritus-sancti) is generally forgiving once you match its basics, but a few issues come up again and again. Here is what each one looks like, why it happens, and the fix.
Slow or stalled growth
This species is naturally slow; ensure steady warmth, high humidity, and bright indirect light rather than overwatering to push it.
Crispy, curling leaves
Low humidity is the usual cause given its rainforest origin; raise humidity well above 60% with a humidifier or enclosure.
Root rot
Soggy mix quickly kills this valuable plant; use a very chunky medium and let the top of the pot dry between waterings.
Weak, undersized leaves
Too little light or a missing support; provide bright indirect light and a moss pole to encourage mature, elongated foliage.
