Cut a 6-inch section of a new shoot from a blueberry bush using a sharp knife.
Trim off the lower leaves with pruning shears. Leave the top leaves in place.
Pour the powdered rooting hormone compound into a bowl. Place the end of the cutting 1 inch deep into the rooting hormone. Cover the end of the stem evenly with the hormone. Purchase rooting hormone at most garden-supply stores.
Plant the shoot in a pot filled with an equal mixture of damp peat moss and sand. Place the cutting 2 inches deep into this soil mixture.
Cover the blueberry plant with clear plastic wrap. Tape the plastic wrap to the bottom of the pot to keep it in place.
Position the pot on a sunny windowsill with filtered sunlight for three weeks. Water the shoot to keep the peat moss damp.
Check the shoot periodically for roots. Pull on it gently; if it resists the pressure, then it has developed roots. When the plant develops roots, remove the plastic and plant the blueberry outdoors in an acidic soil high in organic matter, with a pH range between 4.5 and 5. Water the blueberry plants with 1 to 2 inches of water each week.
