These plants do best in medium to bright indirect light. Their thin, delicate leaves will quickly burn or bleach in direct sun, so limit exposure to only 2-3 hours max. Non-variegated varieties can tolerate lower light levels, where variegated types of Syngoniums need consistent bright light to maintain their variegation.

To help prevent root rot, let your Syngonium dry out a little between waterings. I’ve found watering about every 10 days in ambient conditions works well. Watch for wilting or droopy leaves, which is a sign of not enough water. If that occurs, slightly increase your watering frequency.

Syngoniums prefer warm temperatures, 65F or above is ideal. Anything below 55F risks cold damage.

Syngoniums will grow just fine in typical household humidity (40-50%) but will thrive in more humid conditions (60-75%). Avoid placing them near vents or areas with drafts, a kitchen or bathroom with plenty of natural light would be a great spot for Syngoniums.

They do best in a chunky, well-draining mix with plenty of drainage in the pot. They can be prone to root rot, so they need plenty of drainage in the soil and pot to keep water from collecting around the roots which leads to rot. I’ve had great success with growing Syngoniums in a chunky aroid mix with plenty of airflow around the roots.

Syngoniums, like other Aroids, contain calcium oxalates in their tissues which are mildly toxic to pets and people if ingested.
