Propagation of Bidens ukambensis S.Moore

Bidens ukambensis S.Moore can be propagated through various methods:

Seed Propagation

The easiest and most common way to propagate Bidens ukambensis S.Moore is through seed propagation. The matured and dried flower heads should be harvested and the seeds collected. The seeds may be sown directly in the field or in a nursery bed. The nursery beds should be well-prepared and have adequate moisture content. The seeds should be sown at a depth of 1-2 cm and the soil should be pressed firmly above them. Germination occurs within 10-14 days. Seedlings can be transplanted into pots or directly into the field when they reach a height of 5-10 cm.

Cuttings Propagation

Bidens ukambensis S.Moore can also be propagated through cuttings. Semi-hardwood cuttings, taken from the healthy plants, should be planted in a rooting medium like sand, peat, or vermiculite. They should be kept in a humid environment with a plastic cover or a misting system. The cuttings should form roots within 4-6 weeks and can be transplanted into the field or pots.

Division Propagation

Division propagation is another method of propagating Bidens ukambensis S.Moore. The matured and healthy plants should be dug up and divided into smaller sections. Each section should have some roots and shoots and these can be planted separately in the field or pots. This method is useful for propagating large-sized plants and can be done during the growing season.
