Propagation of Salsola kali L. ssp. tragus (L.) Celak.
Salsola kali L. ssp. tragus (L.) Celak., commonly known as prickly saltwort, is a widely distributed annual herb that belongs to the family Amaranthaceae. It is adapted to grow in arid and semi-arid regions and can thrive in poor, saline soils. This plant can be propagated by several methods that are simple and cost-effective.
Seed propagation
The easiest and most common method of propagating Salsola kali L. ssp. tragus is by seed. The seeds are small and black, and a single plant can produce thousands of them. The best time to collect the seeds is when the plant has turned brown and the seeds have matured. The seeds can be stored in airtight containers in a cool and dry place for at least two years. To propagate the plant from seeds, the seeds should be sown after the last frost in the spring, directly into the soil. The soil should be well-drained, and the seeds should be covered with a thin layer of soil. Within two weeks, the seeds will germinate, and the seedlings will begin to grow.
Cutting propagation
Another method of propagating Salsola kali L. ssp. tragus is by cuttings. This method involves taking stem cuttings from the parent plant and rooting them to produce new plants. The cuttings should be taken in the spring, after the new growth has begun. The cuttings should be about 4-6 inches long and should be planted in a well-draining potting mix. The soil should be moistened, and the cuttings should be watered regularly until they start to grow new leaves and roots.
Division propagation
Salsola kali L. ssp. tragus can also be propagated by division. This method involves digging up the entire plant and dividing it into smaller sections. Each section should have a portion of the root system and some shoots. The sections should be replanted in a well-draining soil in a sunny spot. The soil should be kept moist until new growth begins.
Propagation of Salsola kali L. ssp. tragus (L.) Celak. can be done by seed, cuttings, or division. The best method depends on the grower's preference and the available resources.
