Self-watering pots: good for some plants, fatal for others
33 of 100 species in this database need it
33 of our 100 species need it. Does this plant want to dry out between waterings? If our entry gives an interval of a fortnight or more, a self-watering pot keeps the roots permanently damp and will eventually rot it. Typically $12 to $45.
Does this plant want to dry out between waterings? If our entry gives an interval of a fortnight or more, a self-watering pot keeps the roots permanently damp and will eventually rot it. If it wants steady moisture, the pot does exactly what you want.
Depends on the plant. Genuinely useful for thirsty, evenly-moist plants. Actively dangerous for anything drought-adapted, which is most of what gets sold in one.
What it actually is
A reservoir below the soil with a wick or a gap that lets the medium draw water up as it dries. The plant regulates its own supply, within limits.
What to avoid
They are commonly sold planted with succulents, which is close to the worst possible pairing. Also, they need a dry-out period every few weeks — a permanently full reservoir causes exactly the anaerobic conditions root rot needs.
Species in this database that need it
These species want water weekly or more often and never want to dry out fully — the only group a self-watering pot genuinely suits.
