Propagation of Vernonia bukamaensis De Wild.
Vernonia bukamaensis De Wild. is a perennial plant that originated from Congo. It is commonly known as Congo Bololo or simply Bololo. This plant is a beautiful addition to any garden, and it has several propagation methods that can be used to increase plants.
Propagation by seeds
Vernonia bukamaensis De Wild. can be propagated by seeds. The best time to start sowing seeds is in the early spring or after the last frost has passed. The seeds should be sown shallowly in a well-draining soil mix and kept moist until they germinate. Germination can take up to three weeks, so patience is required.
Propagation by cuttings
Another propagation method that can be used for Vernonia bukamaensis De Wild. is by taking cuttings. This method is advantageous as it ensures that the new plants are identical to the parent plant in every way.

The stems should be dipped in a rooting hormone, and then planted in a moist soil mix containing perlite or vermiculite. The cuttings should be kept moist but not waterlogged until they have developed roots.
Propagation by division
Propagation can also be done through division. This is a more straightforward method where the plant is simply divided into smaller sections. The best time to do division is in spring or early summer, and the plant should have a minimum of three shoots. The sections should be separated carefully and planted immediately in a well-draining soil mix. They should be kept moist until they establish roots.
The propagation methods for Vernonia bukamaensis De Wild. ensure that you can multiply the plants and give them as gifts to friends and loved ones. These methods are simple and can be done even by novice gardeners.
