Propagation of Arctotis paleacea Thunb.
Arctotis paleacea Thunb. can be propagated through various methods. The following are some of the most common propagation methods:
Seed propagation
Arctotis paleacea Thunb. can be propagated through seeds. The seeds should be sown in well-draining soil during spring or early summer. The soil should be kept moderately moist. Germination should occur within 10-21 days. Once the seedlings have developed sufficient foliage, they can be transplanted to larger containers or directly planted in the garden.
Division
Another common propagation method for Arctotis paleacea Thunb. is through division. This method works well with mature plants that have multiple stems. The plant should be carefully lifted from the soil, and the root ball should be divided into several clumps. Each clump should have at least one stem and a portion of the root system. The clumps can be replanted in new containers or directly in the garden.
Stem cuttings
Arctotis paleacea Thunb. can also be propagated through stem cuttings. This method works best with young, softwood stems. The cuttings should be taken during the spring or early summer. The leaves on the lower portion of the stem should be removed, and the stem should be inserted into moist soil. The soil should be kept moist, and the cutting should root within 4-6 weeks. Once the cutting has started to develop roots, it can be transplanted to a larger container or directly planted in the garden.
