Propagating by division is kind of cheating because it isn’t REALLY propagation…you’re just splitting the plant. But splitting raven ZZ plants is really easy. Just take it out of the pot, find an area where you can gently break the rhizomes apart, and split them. A 2011 study suggested that there are no restrictions on gene flow between the Californian and Holarctic common raven groups, and that the lineages can remerge, effectively reversing a potential speciation. [23] Root rot is the most common issue and results from overwatering. You can tell the Raven ZZ has root rot when the leaves turn yellow and mushy. At that point, stop watering for 4-6 weeks and make sure your soil drains well enough. If not, add sand or clay pebbles to ensure proper drainage.
