    Stem Cutting

    By chopping the stem of this Thunbergia alata (Black Eyed Susan Vine) vine by 3 to 4 inches, you can reproduce it. Following that, either you submerge a portion of the plant’s lower stem, or if the stem is 4 inches in length, keep the water level no higher than 2 inches.

    After that, plant it in the ground for more growth as soon as the root development process starts. However, because it has been observed that the plant thrives in soil, you may also grow its cutting straight in moist soil. Just remember to take care of the plant as needed.

    Last Method: (Not a method , Plant Re-Germination)

    Black eyed susan vine leaves turning yellow

    Black eyed Susan vine leaves can turn yellow for a variety of causes, including nutritional deficiencies, early frost damage, and parasites that resemble spider mites. Overwatering and underwatering are some more reasons why black-eyed plant leaves become yellow. By nourishing the plant and covering it with a frost blanket in the winter, you can resolve the issue with the plant’s yellow leaves.

    When the soil feels dry, water every one to two days to prevent yellowing of the foliage caused by underwatering stress. Black-eyed susan vine roots can be damaged by overwatering, which can result in yellow leaves. To revive your plant, stop adding water, let it dry, and then water it. Always use your index finger to feel the soil for plants, and only add water if it feels dry.
