In Japan, it grows naturally in the south of Kyushu Island and the Ryukyu Islands. Height 1.50-5 m, crown crown width 1.80-3 m. The stem is 20-25 cm in diameter, with clustered leaves falling off. The patterns revealed by the bases of the fallen leaves are striking. Older individuals can sometimes have branched stems. The leaves are evergreen, feathery and 90-150 cm long. Leaflets are 7-8 cm long, dark green, waxy and quite hard. It is dioecious. It does not form true flowers. Cones of male individuals emerge from the shoot tips, similar to pine cones, up to 60 cm long.
The bronze-colored, oval, 2.5- 7.5 cm long, orange-red seeds in the macrosporophyll ripen in two months. It grows well in warm regions. It can grow up to -7 °C. It is drought resistant after it develops well. It grows best in soils with moderate water and moisture demand, good drainage and rich in nutrients. Cycas revoluta, called the palm, is not a true palm. It belongs to the Cycad group, one of the first seed plants of the earth.
The Cycas revoluta, commonly known as the Sago Palm or King Sago Palm, is not a true palm but rather a cycad. Despite its name, it is not related to palms. Cycads are ancient plants that have been around for millions of years. Here are some general care tips for Cycas revoluta:
- Cycas revoluta prefers bright, indirect light. It can tolerate some direct sunlight, especially morning sunlight, but too much direct sun can scorch the leaves.
- Indoors, place the plant near a bright window, but protect it from intense midday sun.
- Allow the soil to dry out slightly between waterings. Overwatering can lead to root rot, so it’s essential not to let the plant sit in soggy soil.
- Water sparingly during the winter months when the plant is not actively growing.
- Use a well-draining soil mix to prevent waterlogged conditions. A mix formulated for cacti and succulents is suitable.
- Temperature and Humidity:
- Cycas revoluta prefers warm temperatures and does well in the typical indoor temperature range of 65-75°F (18-24°C). It can tolerate brief periods of cooler temperatures.
- Maintain moderate humidity. Indoor air is often dry, so occasional misting can help increase humidity.
- Fertilize during the growing season (spring and summer) with a balanced, slow-release fertilizer. Reduce or eliminate fertilizer during the dormant winter months.
- Remove yellow or brown fronds to keep the plant looking tidy. Use clean, sharp pruning shears to avoid damaging the remaining foliage.
- Pests and Diseases:
- Keep an eye out for pests such as scale insects and mealybugs. If you notice any, treat them promptly with insecticidal soap or neem oil.
- Cycads are generally resistant to many diseases, but overwatering can lead to root rot.
- Repot the Sago Palm when it outgrows its current container, typically every 2-3 years. Use fresh, well-draining soil during repotting.
- All parts of the Cycas revoluta are toxic if ingested, especially the seeds, so keep it out of reach of children and pets.
Remember that individual plant care can vary, and it’s essential to observe your specific plant’s needs. Adjust care routines based on the plant’s response and environmental conditions.
