Propagation of Dicoma superba S.Moore var. angustifolia S.Moore
Dicoma superba S.Moore var. angustifolia S.Moore can be propagated through two methods:
1. Seeds Propagation
Seeds provide the easiest method to propagate Dicoma superba S.Moore var. angustifolia S.Moore. Here are the steps to follow:
- Harvest the seeds from the dried-up inflorescences;
- Remove the chaff by threshing the seeds;
- Sow the seeds in nursery beds or directly in the field;
- Cover the seeds lightly with soil.
- Keep the soil moist and wait for the germination.
2. Vegetative Propagation
Vegetative propagation is a technique in which a part of the parent plant is used to produce new plants. Here are the two methods used in the vegetative propagation of Dicoma superba S.Moore var. angustifolia S.Moore:
- Root Cuttings: A number of cuttings are made from the roots of the parent plant, and these cuttings are then planted in a suitable medium to encourage the growth of roots and new plants.
- Stem Cuttings: Stem cuttings are made from the parent plant's stems early in the growing season. The cuttings are then planted in a suitable place and kept moist to encourage root growth.
Dicoma superba S.Moore var. angustifolia S.Moore can be propagated using either of the two methods above, depending on the intended use and other factors such as cost and availability of planting materials. In any case, it is important to ensure that the plant is healthy and that all the necessary precautions are taken to ensure that the new plants thrive.
