How Often to Water a Dieffenbachia
Water your Dieffenbachia about every 8 days in average conditions — but check the soil first. Water when the top inch or two of soil feels dry.
| Conditions | Summer | Winter |
|---|---|---|
| Small pot (4") | every 5d | every 9d |
| Medium pot (6") | every 7d | every 11d |
| Large pot (10"+) | every 9d | every 15d |
Dieffenbachia prefers medium indirect light and average humidity. Overwatering is the most common cause of problems — when unsure, wait a day and check again.
