Do self-watering pots actually work, or do they cause root rot?

Specialist-community consensus is mixed but largely positive for the right plants. Across r/houseplants and r/IndoorPlants threads we read, many growers report less watering stress and healthy roots, while others warn that moisture-loving setups can give 'wet feet' to drainage-sensitive plants like citrus. The practical takeaway from reviewers: self-watering reservoirs suit thirsty plants and forgetful waterers, but you should pair them with good drainage and avoid them for cacti, succulents, and citrus.
