Propagation of Dicoma hindana
Dicoma hindana S.Ortíz & Rodr.Oubiña can be propagated through seeds or stem cuttings. The following are detailed information on the propagation methods:
Propagation through seeds
The seeds of Dicoma hindana can be collected during the flowering season, which is usually from June to August. The collected seeds should be dried and stored in a cool, dry place before sowing.
To sow the seeds, prepare a seedbed by mixing equal parts of sand and loam or any other suitable soil mix and level the surface. The seeds should be sown thinly and covered lightly with soil. Water the bed gently to keep it moist and keep the seedbed in a shaded area. The recommended temperature for germination is between 20-25°C.
After germination, the seedlings should be carefully lifted and transplanted into individual pots when they are large enough to handle. Young plants should be kept in a shaded area until they are mature enough to be planted in the field.
Propagation through stem cuttings
Dicoma hindana can also be propagated through stem cuttings. Take cuttings from young, vigorous shoots during the growing season. Cuttings taken during spring will root quickly.
The cutting should be around 5-10cm long and should have at least two nodes. Remove all the leaves except for the top two. Dip the cut end of the stem in rooting hormone and plant it in rooting medium, such as sand or a mixture of sand and peat. Place the cutting in a humid, warm, and brightly lit area. The temperature should be between 18-24°C.
Keep the rooting medium moist but not waterlogged and mist the cuttings regularly. Rooting should occur within four to six weeks. Once the new plants have established roots, they can be transplanted into individual pots or directly into the field.
