Sago palm

CycasCycadaceae
Also: Cycad, Cycas, Japanese sago palm
AT A GLANCE
Part shade Water: little H3down to −5 °C 60 cm–1.5 m tall · 1–1.5 m wide In a pot: yes

Not a palm but a cycad: slow, very long-lived and toxic in every part — keep it away from pets.

Care

Light

Bright light; outdoors sun to part shade, indoors a bright window.

Water

Low — water well when the compost is dry; almost none in winter. The trunk rots easily.

Soil

Very free-draining, gritty soil or compost.

Pruning

Remove only fully dead fronds. Don't cut yellowing fronds while the new flush is growing — the plant draws on them.

Feeding

A palm or balanced feed with magnesium two or three times in summer.

Propagation

Offsets (pups) removed from the trunk base, dried and potted in grit; slow.

Month by month

Months change with the climate: in southern Italy tomatoes go out two months earlier than in England.
