Sago Palm (Cycas revoluta): Ancient "Living Fossil" for Patient Growers

Botanical Name: Cycas revoluta

Sago Palm belongs to one of the oldest plant families—a cycad, not a true palm. One of the most primitive plants, dating to the dinosaur era 200 million years ago.

Extremely slow-growing but develops a substantial trunk over many years. Topped with a rosette of shiny, stiff, narrow fronds arching at tips. Rigid leaves appear tough but damage easily—handle carefully.

Care Philosophy

• Don't like wet feet: Keep soil on dry side.
• Daily light + light fertilizer in growing season.
• Don't disturb: Repot only when necessary. Prune dead fronds anytime.

Common Problems

Yellowing leaves = overwatering. Follow watering instructions to avoid crown rot—nearly impossible to treat. Scale insects are the main pest—inspect often, treat immediately.

CAUTION: All parts poisonous, especially seeds. Keep away from children/pets.

Sago Palm Care Quick Reference

• Origin: Tropical Asia
• Height: Up to 6 ft (1.8 m) indoors. Stays dwarf in small pot. Popular bonsai.
• Light: Bright with some direct sun. Rotate ¼ turn weekly in growing season to prevent leaning.
• Water: Water soil, not crown (causes fatal crown rot). Thoroughly water, allow to dry slightly between, never completely. Less in winter. Good drainage.
• Humidity: Requires moist air. Humidifier best.
• Temperature: 60–75°F (16–24°C)
• Soil: Cactus mix, or 2 parts peat-based mix + 1 part sharp sand/perlite
• Fertilizer: Monthly spring–fall with liquid fertilizer (18-6-18) at half strength. Only when watering. Slow-release at half package rate. Overfeeding = shriveled leaves.
• Propagation: Seeds (months to germinate, years to tree). Mature plants produce offsets ("pups")—separate and pot individually.
