Care tips
- Water when the top half of the soil is dry; it forgives forgetfulness

- Wipe dust off the broad leaves every month or two
Common questions
How often should I water a cast iron plant? +
A healthy indoor cast iron plant typically wants water every 12 days or so. Treat that as a starting cadence, not a rule — pot size, light, and season all shift it, so check the soil before you pour.
How much light does a cast iron plant need? +
A cast iron plant does best in low to medium indirect light. If it stretches, fades, or stalls, adjust its spot before changing anything else.
Is a cast iron plant toxic to cats or dogs? +
The cast iron plant is generally considered non-toxic to cats and dogs per the ASPCA plant lists — still best kept out of chewing range.
Typical guidance for a healthy cast iron plant — your own conditions (and your vet, for animals) come first.
