Pet-safety information is a general guide from the ASPCA's toxic-plant database and covers cats and dogs only. "If eaten" summarises the symptoms ASPCA lists for that plant; how an animal actually reacts depends on how much it ate and on the animal. It isn't exhaustive, isn't veterinary advice, and individual animals vary — never rely on it as the sole basis for a decision about your pet. If you think your pet has eaten a harmful plant, contact a vet immediately.
Care
- WaterEvery 4–7 days
- LightDirect sun
- HumidityAverage humidity
- Temperature-15–26 °C
The same interval the Sabz app schedules reminders from. In autumn and winter the app stretches it; see houseplants in autumn.
Common problems
- Thin, weak stalks — the crown is exhausted or the pot is too small
- Flower spike appearing — cut it out at the base; it drains the crown
- Leaves eaten — worth noting the leaf blades are toxic to people as well as pets
In the app
Add a rhubarb to Sabz and the watering interval above becomes a reminder, the toxicity verdict sits on the plant's own page, and when a leaf turns, the Check-up reads what you have actually logged to say why.
