Propagation of Aristida schiedeana Trin. & Rupr. var. orcuttiana (Vasey) Allred & Valdés-Reyna
Aristida schiedeana Trin. & Rupr. var. orcuttiana (Vasey) Allred & Valdés-Reyna can be propagated through both sexual and asexual methods. The best time for propagation is during spring and summer when the plant is actively growing.
Seed Propagation
The easiest method to propagate Aristida schiedeana Trin. & Rupr. var. orcuttiana is through seed propagation. The seeds of the plant usually germinate naturally during the rainy season, but they can also be collected and sown in well-drained soil with good sunlight exposure and a pH range of 6.5 to 8.0. Prior to sowing, the seeds should be soaked in water overnight and then dried thoroughly. The seeds should be sown 1-2 cm deep into the soil and gently pressed down for good contact. The soil should be kept moist until germination, which usually occurs within 2-3 weeks.
Division
Aristida schiedeana Trin. & Rupr. var. orcuttiana can also be propagated through division of the root clumps. The plant should be dug up carefully, and the roots should be gently separated into smaller clumps of 2-3 stems. Each clump should have a good root system intact. The divisions should be replanted immediately and kept moist until they establish in the soil.
Cuttings
Cutting propagation is another method of propagating Aristida schiedeana Trin. & Rupr. var. orcuttiana. Softwood cuttings can be taken during the growing season, from May to August. Cuttings should be approximately 10 cm long, and the leaves on the bottom of the stem should be removed. The cuttings should be planted in a mixture of sand and peat moss and kept moist. Rooting should occur within 3-4 weeks.
