Plant Doctor Pilea Peperomioides Plant Care Guide:
Pilea Peperomioides aka "Chinese Money Plant" or "UFO Plant" needs ample bright filtered, indirect light to thrive, but no direct sunlight as their leaves can burn easily. They will grow tiny babies if given enough light!
Allow soil to dry out slightly in between waterings. Water about once every 7-10 days depending on growing conditions and time of year. They will need less water in the winter.
You can pluck the babies out and plant them directly into soil to propogate. Make sure the tiny roots are still intact to do so. If no roots are visible, out the stem in water and leave it there until roots grow, then plant in soil.
