Propagation of Pelargonium auriculatum Willd.
Pelargonium auriculatum Willd. is a species of Pelargonium known for its ornamental and medicinal uses. It is a native of South Africa and is primarily propagated by vegetative means.
Softwood Stem Cuttings
Softwood stem cuttings are the most commonly used method for propagating Pelargonium auriculatum Willd. This method involves taking cuttings in the spring or early summer when the new growth is still flexible. The stem cutting should be approximately 10 cm long and should have three to four leaves. Remove the leaves from the bottom of the cutting, leaving only one or two at the top.
Dip the cuttings into rooting hormone and plant them in a pot with well-draining soil mix, keeping the soil moist but not too wet. Cover the pot with a clear plastic bag and place it in a warm and bright location, but out of direct sunlight. The cuttings should root in approximately four to six weeks.
Leaf Cuttings
Leaf cuttings can also be used to propagate Pelargonium auriculatum Willd. This method involves taking a leaf cutting that includes the petiole. The petiole should be approximately 2-3 cm long. Insert the petiole into a well-draining soil mix and cover it with plastic or a clear plastic bag to maintain humidity and moisture. Keep the pot in a bright location, but avoid direct sunlight. The leaf cuttings should root in approximately six to eight weeks.
Division
Pelargonium auriculatum Willd. can also be propagated by division, but this method is less common. It involves dividing the plant into smaller sections and replanting them. This method is typically used with mature and established plants.
Propagation of Pelargonium auriculatum Willd. can be an easy and rewarding process, leading to the creation of new plants with the same desirable attributes and characteristics of the parent plant.
