Q. I
received a beautiful African violet as a gift this spring. It has
been in bloom constantly! I would like to start another plant to
give to my sister. Can you tell me how to go about it?
A.
African violets (Saintpaulia spp.) are easy to propagate by
leaf cuttings. Remove a healthy, firm leaf from the middle of the
plant by reaching in and snapping or cutting it at its point of
origin on the main stem. Trim the leaf stalk (petiole) back to 11/2
inches or so, making the cut at a 45-degree angle (It exposes more
surface area where roots will form).
You can make a
rooting medium using one part sand to one part vermiculite, or you
can use a soil-less seed starting mix. Fill a small container with
the mix, and moisten it so that it feels like a wrung-out sponge --
moist but not sopping wet. Make a hole in the center with a pencil.

You can coat
the leaf stalk with a rooting hormone such as Rootone or Dip N'
Grow, although it is not absolutely necessary. Insert the trimmed
leaf stalk into the hole so that the base of the leaf just touches
the surface of the mix and firm the mix around it for support. Place
the pot in a clear plastic bag to maintain high humidity around the
leaf. Put the bagged pot in a bright area out of direct sunlight to
avoid cooking the cutting. Monitor the cutting and remove the bag
when you see new little plants forming.
Roots should form
at the base of the leaf stalk in several weeks, followed by small
plants at the soil surface. Once they have four leaves and are large
enough to handle, remove them from the container and gently separate
the small plants. Pot them into individual pots, using a potting mix
for African violets.
