Propagation of Oldenburgia paradoxa Less.
Oldenburgia paradoxa Less. is a small, drought-resistant shrub. Propagation of this plant can be achieved through vegetative and seed methods.
Propagation through Seeds
Propagation of Oldenburgia paradoxa through seeds is an easy and reliable method. Seeds can be collected when the fruits have matured and ripened. The seeds should be planted in well-prepared soil, which should be kept moist but not waterlogged. Germination generally occurs within two weeks of planting. Plants grown through seeds generally take about three to four years to reach maturity.
Propagation through Cuttings
Propagation through cuttings is a common method for Oldenburgia paradoxa. Cuttings should be taken from mature, woody stems at the beginning of the growing season. The cuttings should be about 10-15 cm long and should have at least two nodes. The lower leaves should be removed, and the cuttings should be treated with rooting hormone. The cuttings should be planted in well-prepared soil and watered thoroughly. The soil should be kept moist, but not waterlogged, until roots develop. It takes about six months for the cuttings to develop into mature plants.
Propagation through Layering
Propagation through layering involves bending a branch or stem of Oldenburgia paradoxa to the ground and covering it with soil. Roots will develop at nodes where the stem comes into contact with the soil. After roots develop, the stem can be cut and transplanted. This method is useful when a mature, established plant is present.
