Lettuce
Lactuca sativa
Toxicity unconfirmed
Fast, shallow-rooted and permanently thirsty — the whole trick is steady water and a bit of shade in high summer. Sow a short row every fortnight rather than all at once, or it all hearts up in the same week.

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 1–3 days
- LightMedium light
- HumidityAverage humidity
- Temperature5–22 °C
The same interval the Sabz app schedules reminders from. In autumn and winter the app stretches it; see houseplants in autumn.
Common problems
- Bolting to a tall bitter spike — heat and dry soil; sow again in some shade
- Slimy brown collapse at the base — slugs, or watering over the leaves at dusk
- Bitter leaves — usually the plant is old or has been short of water
In the app
Add a lettuce 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.
