These are my African Violets, which sit on this plant stand in front of a door in the kitchen. There are so many trees in the yard that I don't have as much sun coming in the windows as I would like, but they do well here.
This is how I root them for new plants.
The easy way:
Just break off a leaf and stick into some dirt in a pot. Use a pen or pencil to make the hole. Just keep it moist and place it where it gets some indirect sun. I've done this many times over the years with good results. Little baby plants will come up in the pot.
The more detailed way:
Dip the stem of the leaf in rooting hormone, place it the hole in the dirt in the pot and put a plastic bag over it. I've never gone to this much trouble, but would probably give you faster results.
Have a great day!
