Propagation of Diplachne chloridiformis Hack. ex Stuck.
Diplachne chloridiformis Hack. ex Stuck., commonly known as Saltgrass or Saline Sprangletop, is a hardy perennial grass that grows well in saline soil conditions. If you are planning to propagate the plant, there are several propagation methods to choose from.
Seed Propagation
The most common method of propagating Diplachne chloridiformis is through seeds. Collect mature seeds from healthy plants and let them dry in the sun for a few days. Sow the seeds in moist soil during the spring season in a greenhouse or a seedbed. Keep the soil moist and warm for proper germination. Once the seedlings have developed two to three leaves, transplant them into individual pots or in the main field at a distance of 30 cm from each other.
Vegetative Propagation
Diplachne chloridiformis can also be propagated through vegetative methods. One way is by dividing the clumps of mature plants in the early spring. Carefully dig out the clumps, and pull them apart to separate the individual plants. Replant the divisions in separate containers or in the field.
Another vegetative propagation method is through stem cuttings. Take stem cuttings of 8-10 cm in length from healthy plants in early spring. Plant the cuttings in moist sand, and keep them under shade with high humidity. Rooting usually occurs in 2-3 weeks, and then transplant the rooted cuttings in the main field at a distance of 30 cm from each other.
