The best time to divide Bidens cinerea Sherff is in the spring when new growth begins to emerge. Care should be taken when dividing the plant to avoid damaging the roots. The new sections should be transplanted into well-draining soil and watered regularly until they become established.
Stem Cuttings
Propagation through stem cuttings can also be used to propagate Bidens cinerea Sherff. This method involves taking cuttings from the plant and rooting them in a soilless growing medium. Cuttings can be taken in the spring and early summer. The stem cuttings should be around 10 cm long and should include at least two leaf nodes. The cuttings should be placed in a well-lit, warm, and humid spot until roots develop. Once the cuttings have established roots, they can be transplanted into individual pots or directly into the garden.
Overall, Bidens cinerea Sherff is a hardy plant that can be propagated using various methods, making it an excellent plant for beginner gardeners.
