The Propeller Plant can easily be propagated by cuttings or removing the offsets. Seed and leaf propagation is also possible with the Propeller Plant. To remove offsets, cut from the main stem with a clean shears. You can also take cuttings to propagate. Especially if your Propeller plant is growing too tall.
Allow the removed offset or cutting to callous over for 3-5 days before planting in well-draining soil. Specifically to ensue the ends heal or scab over. Water propagation also works well and is my favorite way to propagate the Propeller Plant.
Check out my cutting that is propagating well in water below. I will wait until a bit more roots form before planting in well-draining soil. Once transferred into soil, I will resume regular watering. In fact I tend to give them even more water in the first few weeks to get them acclimated to the soil.
