Sago palm (Cycas revoluta) care

Palms · easy to keep

Last updated

Sago palm (Cycas revoluta) wants bright light, with some direct sun. Water it every 2 weeks. Water thoroughly when the top half of the pot has dried out, and much less in winter. Keep water out of the crown at the top of the trunk. Pot it in gritty, free-draining compost. A palm feed with micronutrients two or three times in spring and summer, and repot every 3 years. Humidity: room humidity is fine. Toxic to cats, dogs and people, and seriously so: every part is poisonous, the seeds most of all.

The sago palm, which is not a palm at all but a cycad, from a group of plants older than the dinosaurs. A stiff crown of glossy, feathery fronds rises from a stout trunk, a single flush a year at most. It is very slow, very tough, and extremely poisonous: every part of it, the seeds most of all, can kill a dog or cat that chews it.

Watering a Sago palm

Water every 2 weeks. Water thoroughly when the top half of the pot has dried out, and much less in winter. Keep water out of the crown at the top of the trunk.

That cadence is the one PlantParlour sets for this species when you name it, and it is deliberately on the cautious side — a plant that asks a day early is safer than one that asks a day late. Log each watering and the reminder moves with the plant rather than with the calendar.

Light

Bright light, with a few hours of direct sun if you can give it. A sago in a dim room puts out few, weak, stretched fronds — and it only makes a flush or two a year to begin with.

Humidity and temperature

Room humidity is fine. Central heating in winter is what turns a comfortable room into a dry one, and it is the usual reason an established plant suddenly browns at the edges or picks up spider mites.

Soil and potting

Cactus or palm compost with extra grit or perlite. The stout trunk and thick roots store water, and a mix that stays wet rots them.

Feeding

A palm feed with micronutrients two or three times in spring and summer. Stop feeding in autumn and start again when you see new growth in spring — feeding a plant that isn't growing just builds up salts in the pot.

Repotting

Repot every 3 years. Every three years or so, and only when the roots fill the pot — it grows slowly and likes a snug pot. Keep the trunk at the depth it was; buried deeper, it rots.

Common problems

Propagation

Pups that form at the base of an older plant can be cut off, left to dry for a week and potted in gritty mix. Seed is very slow. Wear gloves either way.

A cutting taken in PlantParlour keeps its link to the plant it came from, so a propagation years later still traces back to the mother plant — which is the point if you ever sell or trade it.

Toxicity and safety

Toxic to cats, dogs and people, and seriously so: every part is poisonous, the seeds most of all. Chewing it can cause vomiting, liver failure and death in dogs and cats. If a pet has eaten any, call a vet or animal poison line straight away rather than waiting for symptoms.

The ASPCA lists Sago Palm (Cycas revoluta, zamia species) as toxic to cats and dogs (checked 26 October 2026).

If your pet has eaten a plant, call your vet, the ASPCA Animal Poison Control Center on (888) 426-4435, or the Pet Poison Helpline on (855) 764-7661. Both are open around the clock and may charge a consultation fee. Take the plant or its label with you.

This is general information, not veterinary advice. We don't test plants: what we say about toxicity follows the ASPCA's published plant list as it stood on 26 October 2026, and that list can change. "Non-toxic" means not poisonous — a pet that eats enough of any plant can still vomit, and fertiliser, pesticide or leaf shine on a plant can harm it. It also only helps if the plant is what you think it is. It covers cats and dogs only; ask your vet about rabbits, birds, reptiles or anything else, and a doctor about children. Read our terms.

Questions people ask

Is a sago palm safe around pets?

No. The ASPCA lists sago palm as toxic to dogs and cats. Every part is poisonous and the seeds are the worst; eating it can cause vomiting, liver failure and death. If a pet has chewed one, call a vet or animal poison line straight away.

How often should you water a Sago palm?

Water every 2 weeks as a starting point — that is the cadence PlantParlour sets for Cycas revoluta. Water thoroughly when the top half of the pot has dried out, and much less in winter. Keep water out of the crown at the top of the trunk. Light, pot size and the time of year all move that number, so treat it as a reminder to go and check rather than a rule.

How much light does a Sago palm need?

Bright light, with a few hours of direct sun if you can give it. A sago in a dim room puts out few, weak, stretched fronds — and it only makes a flush or two a year to begin with.
