This plant is native to Southeast Asia and thrives well in tropical regions. Propagation of Desmodium hirtum Guill. & Perr. forma delicatulum can be done through various methods such as by seeds, stem cuttings, and division.
Propagation by seeds
Propagation by seeds is the most common method used in propagating Desmodium hirtum Guill. & Perr. forma delicatulum. The seeds should be collected when mature and dry. The seeds should be stratified by placing them in a moist medium at a temperature of 5-10°C for 2-3 weeks. After stratification, sow the seeds in a well-drained pot filled with potting soil and cover with a thin layer of soil. Water the soil carefully and keep it moist until the seeds germinate which takes about 14-21 days.
Propagation by stem cuttings
Propagation by stem cuttings is another method used in propagating Desmodium hirtum Guill. & Perr. forma delicatulum. This method is common for plants that are not easily propagated by seeds. To propagate Desmodium hirtum Guill. & Perr. forma delicatulum through stem cuttings, take 8-10 cm cuttings from healthy plants with a sharp, sterile knife. Strip off the foliage from the bottom of the cutting and dip the cut end in rooting hormone. Plant the cuttings in well-drained soil and keep them in a bright, warm location with consistent moisture. Roots will develop in about 3-4 weeks.
Propagation by division
Propagation of Desmodium hirtum Guill. & Perr. forma delicatulum can be done through division. This involves dividing the mother plant into small clumps and replanting them separately. Early spring or fall is the best time to divide Desmodium hirtum Guill. & Perr. forma delicatulum. Divide the plant by carefully digging up the root ball, then teasing out the smaller clumps with a sharp, clean knife. Each division should have healthy roots and shoots. Replant the small clumps in prepared soil and water them regularly.
