An ancient plant that is tough and reliable if given proper light. Like several other plants with “Palm” in their common name, Sago Palm isn’t a true palm, it’s actually a cycad.
Background
Cycas revoluta, most commonly known as the ‘Sago Palm’, is a plant in the Cycadaceae family. It is native to Japan but is widely seen throughout the world as an ornamental, landscape, or indoor plant. It is winter hardy to zones 8+.
Size
Very, very slow-growing as a houseplant, hence why larger Sago Palms tend to on the expensive side. This is a plant that does not necessarily mind becoming root-bound. Your Sago Palm will likely stay the same size for years.
Growing Conditions
Light
For best success, Sago Palms should be in an area that receives fairly bright light, but medium light can also be fine. If a Sago Palm is not receiving enough light, the fronds will start to turn yellow.
Watering
Does not require very frequent watering as Sago Palms can store a lot of water and they are also quite tolerant of dry conditions. If you have a larger Sago Palm, watering once every few weeks might be all that is required. A smaller Sago Palm in a small pot will require slightly more frequent watering however.
Potting Mix
Use a potting mix that is very well-draining since they do not like to be soggy or wet whatsoever. Cacti and succulent potting mixes would work as-is, otherwise add some extra perlite, pumice, or coarse sand to an all-purpose potting mix.
Humidity
Sago Palms are fine with moderate humidity. However, in low enough humidity the tips of the leaves (fronds) might start browning.
Fertilizer
Does not need much fertilization since it is a slow-growing plant. Fertilizing during the colder months can actually cause problems for your plant. This is a plant I would say you can get away with only fertilizing once a year during the summer.
Propagation
Propagated from the pups that can grow off of the base of the plant.
Toxicity
This is one of the most toxic houseplants, so be careful! All parts of this plant are toxic. Be sure and wash your hands after handling this plant.
Potential Problems
Yellowing fronds. The most common issue tends to be yellowing of the fronds. This might be due to the plant not receiving enough bright light. Remember to place your Sago Palm in an area that receives bright light, and also remember that each time you water it is helpful to rotate the plant slightly.
Browning fronds. Browning of the leaf tips is likely more related to humidity.
Pests. Can be susceptible to scale/mealybugs.
