Propagation through seeds
The seeds of Ammannia auriculata Willd. var. elata (A.Fern.) A.Fern. can be collected from mature plants and used for propagation. The best time to collect the seeds is when the fruit capsules turn brown and start to split open. These seeds can be sown directly into the soil or propagated in a seedling tray. If sowing directly into the soil, the seeds can be covered with a thin layer of soil and kept moist until they germinate. If using a seedling tray, the seeds can be sown in a well-draining potting mix and kept moist, with the tray covered with plastic wrap or a lid until the seeds germinate.
Propagation through stem cuttings
Stem cuttings of Ammannia auriculata Willd. var. elata (A.Fern.) A.Fern. can be taken from healthy plants during the growing season. The stem cuttings should be 4-5 inches in length and have at least 2-3 nodes. The cuttings can be planted directly into the soil or propagated in a rooting hormone solution and then planted into the soil. The cuttings should be planted 1-2 inches deep into the soil and kept moist until they develop roots and start to grow. It is important to keep the soil moist during the propagation process to ensure successful rooting.
