The soil should be kept moist but not waterlogged. Check the soil moisture using a moisture meter or by inserting a finger 1-2 inches into the soil. Water immediately if the soil is dry.
Fertilization
Provide regular fertilization to enhance the growth and health of Pseudarthria macrophylla Welw. ex Baker. Use a balanced fertilizer with a 2:1:1 or 3:1:2 ratio of nitrogen, phosphorus, and potassium. Apply the fertilizer during the growing season (spring and summer) once per month. Do not fertilize during the dormant season (fall and winter).
Pruning
Pruning helps to maintain the shape and size of Pseudarthria macrophylla Welw. ex Baker. Prune the plant in late winter or early spring before the growing season begins. Remove any damaged, diseased, or dead branches/leaves. Also, prune any branches that are crossing or rubbing against each other. Do not prune more than one-third of the plant's growth in a single pruning session.
Propagation of Pseudarthria macrophylla Welw. ex Baker
Pseudarthria macrophylla Welw. ex Baker, commonly known as the wild groundnut or Nigerian groundnut, is a leguminous plant native to tropical and southern Africa. It is a popular plant among horticulturists and gardeners because of its beautiful foliage and colorful flowers. Propagation of this plant can be achieved through various methods, including seed propagation, stem cuttings, and layering.
Seed Propagation
Pseudarthria macrophylla can be propagated from seeds. Seeds should be sown in well-draining soil and covered with a thin layer of soil. The soil should be kept moist but not waterlogged, and the seeds should be germinated in a warm and humid environment. The germination period is usually around 2 to 4 weeks.
Stem Cuttings
Pseudarthria macrophylla can also be propagated from stem cuttings. The stem cuttings should be taken from a healthy plant and should be around 6 inches in length.

Rooting should occur within 4 to 6 weeks.
Layering
Layering is another effective method of propagation for Pseudarthria macrophylla. This involves burying a stem into the soil while it is still attached to the parent plant. The stem should be bent downwards, and a small notch should be made in the middle of the stem. The stem should then be buried in soil with the notched part exposed above the surface. Roots should develop at the notched area, and once the roots are well-established, the stem can be cut and transplanted to a new location.
Overall, Pseudarthria macrophylla is an easy-to-propagate plant that can be propagated through various methods. With proper care and maintenance, the plant can thrive and produce beautiful flowers and foliage.
