Repulsive Smell from Meyer Lemon Pots: Root Rot from Standing Water

A foul odor when watering, plus yellowing leaves and weak flowers, indicates the pots sit in drainage water. After 15 minutes, excess water must be discarded—otherwise roots suffocate and rot, producing anaerobic smell. The "slimy slug" was likely a fungus gnat larva or decay organism.

Fix

• Remove saucers or elevate pots so they never sit in water.
• Repot if soil is soupy; use fast-draining citrus mix.
• Water only when top 2 inches are dry.
• Provide maximum indoor light (south window or grow light).
• Fertilize lightly with citrus formula.

Healthy roots = no smell, better foliage and bloom.
