Propagating geraniums, also called pelargoniums, is a great way to multiply your plants. If you don’t have any geranium plants, take a few cuttings from a friend that does. They are quick and easy to root from stem cuttings.
Cut a stem 4-6 inches long off the mother plant at a 45 degree angle just below a leaf node. That is where the leaves are growing from the stem. Remove the lower leaves (leaving three or four), the stipules (small leaf-like structures along the stem) and any flowers or flower buds.
Fill a planting pot with well-draining soil and make a hole in the center with a pencil or your finger. Put the stem cutting in the hole, firm soil around it and water. Label it if you know what color the flower is. Place the pot where it will receive light but out of direct sunlight such as a windowsill or outside if weather permits. Keep the soil moist but not soaking wet. It will only take a few weeks for the cuttings to root. Give them a gentle tug and if there is resistance they are ready to pot up into a larger pot. Enjoy your free geranium plants.
