When I got my new Oyama African violet self-watering pots, I hurried to transplant as many of the African Violets into them that I could. I picked up one carefully, but the stem snapped off in my hand. Nothing was connected to the roots.
I examined the stem, and found that the African violet had grown in two sections. I cut the sections apart, stuck one in water and stuck the other in wet dirt. I trimmed leaves from both plant segments. Without roots, there were a limited number of leaves that basic osmosis could support, and so cutting down the number of leaves gave the plant the best chance to survive. I didn't trim off the flowers; that part of the plant can be a good source of cloning material, although to do so I would need to read up on that particular cloning technique. I tried to leave as many options open as possible. I also placed the best leave/stem combinations through aluminum foil into a glass of water. The leaves were regularly misted (African violets can absorb some water through the leaves), and the piece of the plant placed in the dirt was kept more moist than normal.
I labeled it "Disaster 1″ because the stem of the next plant I went to transplant was rotted, necessitating another emergency attempt to propagate the African violet.

This is the piece of the stem that I stuck in the damp soil. The plant is thriving. I'm surprised this worked as well as it did, but I'm not going to complain. This plant is doing amazingly well. At some point, when I feel the plant has developed a good root system, I will transplant it into an Oyama pot.

Here's the piece of the stem I put in water. You can see the roots growing in the water, and the flower stems I left on. I apparently won't need those flower stems, but I'm a bit reluctant to remove them just yet. I like to keep my options open, just in case. I'll let the roots grow a bit more and then place this plant in soil.
I didn't photograph the leaves, but they were stuck through the aluminum foil in a manner similar to this plant and have developed some roots — though not as well as this plant.
I've now got 6 versions of this African violet, and I'm wondering what to do with them all! I've thought of giving them to some friends in the area, once I have them growing well. African violets are much less delicate than they were when I was growing up and played with the plastic African violet plant at my Aunt Edna and Uncle Bob's house. Still, they can be delicate, and giving them as gifts can leave the recipient feeling guilty when the plant dies. My sister-in-law was actually annoyed with me when I gave her one. I gave it to her in an Oyama pot. The Oyama pot is two-pieced. The plant is placed in a special lid with some pearlite over the cup, and the cup is filled up to the fill line with water. That's all you have to do to keep the African violet watered properly. My sister-in-law's violet is still thriving, and I gave it to her about a decade ago. So if I'm giving away African violets, I guess I need to buy more of the Oyama pots to do it right!
