We started by first carefully cutting a few select leaves off the middle part of the mother plant, a ruffled, purple African violet given to me as a gift that has been growing really well in my kitchen window- a bright, humid area with little direct sun. Once the violet leaves were severed from the mother plant with about a one inch length of stem attached, I carefully sliced the stem lengthwise (to have more rooting surface and because that's what my research told me to do) and inserted stems into moist, coarse rooting medium. The potted leaf cutting container were then placed into an old plastic mini 'greenhouse' from the grocery store that was used for croissants. (Recycled trash is treasure!)
If we planted them correctly and we continue to monitor the rooted leaf cuttings, we may in fact have a bunch of new African violet babies ready by springtime.
