Propagation of Opuntia chlorotica Engelm. & Bigelow var. santa-rita Griffiths & Hare
Opuntia chlorotica Engelm. & Bigelow var. santa-rita Griffiths & Hare, commonly known as the Santa Rita prickly pear, is a popular ornamental plant in the Opuntia genus due to its attractive lavender-purple pads. Propagating this plant can be done through multiple methods.
Propagation by Seed
One of the most common methods of propagating Opuntia chlorotica var. santa-rita is through seed propagation. The seeds should be collected from ripe fruits and air-dried for two to three days. Once dried, the seeds can be planted in well-draining soil and kept in a semi-shaded area. Optimal germination temperature is between 60 and 70°F (15.5 and 21°C), and germination can take approximately one to three months. The young seedlings can be transplanted to their permanent location once they are large enough to handle.
Propagation by Cuttings
Propagation by cuttings is another method that can be used to propagate Opuntia chlorotica var. santa-rita. Cuttings should be taken in the spring or summer when the plant is actively growing. The cuttings should be allowed to dry for at least a week to form a callus before planting them in well-draining soil. Cuttings should be planted two to three inches (5 to 7.5 cm) deep and kept in a semi-shaded area until they root and start to produce new pads.
Propagation by Division
Propagation by division can also be done with Opuntia chlorotica var. santa-rita. This method involves dividing the plant into smaller sections by cutting through the pads and root system. Each section should have at least two to three pads and a healthy root system. The divided sections can then be replanted in well-draining soil in a semi-shaded area until they establish their root system and start producing new growth.
