Non-toxic to cats and dogs

Grows in bark, not soil — water by soaking, then draining fully, roughly weekly. Bright indirect light and a cool night trigger re-blooming.

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 7–10 days
  • LightBright, indirect
  • HumidityHigh humidity
  • Temperature18–27 °C

The same interval the Sabz app schedules reminders from. In autumn and winter the app stretches it; see houseplants in autumn.

Common problems

Orchid leaves wrinkled and limp

Wrinkled, leathery leaves on a moth orchid mean the roots are not delivering water — either because they have dried out completely or because they have rotted in a pot that never drains. Look at the roots through the clear pot: firm and green or silver is healthy, brown and hollow is rot. Water by soaking the pot for ten minutes then draining fully, roughly weekly, never leaving it standing in water.

Orchid not flowering again

A moth orchid re-blooms when it gets bright indirect light and a few weeks of cooler nights — around fifteen degrees — in autumn, which is what sets the flower spike. Keep the old spike if it is green and cut it back to just above a node; if it has gone brown, cut it at the base. Then bright light, a light feed, and patience: months, not weeks.

Orchid yellow lower leaf

One lower leaf going yellow and dropping, with everything else firm, is normal ageing — an orchid sheds its oldest leaf from time to time. Several leaves yellowing together, or the newest leaf yellowing, is a root problem: check them, and if they are rotting, repot into fresh orchid bark.
