Snake Plant Brown Spots: Water, Light, and Care Adjustments

Diagnosing the Problem

A spreading brown spot on a snake plant (Sansevieria) leaf—despite no overwatering—suggests either excessive direct sun or residual moisture issues. These succulents thrive in bright indirect light; intense sun causes sunscald (brown, crispy patches). Even infrequent watering can rot roots if soil lacks drainage.

Corrective Steps

1. Relocate to bright shade or filtered light—north/east window ideal.
2. Check soil: Should be gritty, fast-draining (cactus mix + perlite).
3. Water only when bone-dry—every 3–4 weeks in winter, 2–3 weeks in summer.
4. Remove affected leaf at soil line if mushy; if firm, it may callous over.

Snake plants are nearly indestructible with neglect—overattention is their main threat.
