Propagation of Clerodendrum Dubium De Wild.
Clerodendrum dubium De Wild. is a beautiful ornamental plant that can be easily propagated through various methods. The plant belongs to the family Verbenaceae, and it is commonly known as White Butterfly or glorybower. The plant is native to Africa, and it is widely grown for its beautiful flowers and attractive foliage. Here are some of the common propagation methods for Clerodendrum dubium:
Seeds
Seeds are the most common method of propagation for Clerodendrum dubium. The seeds should be collected from ripe fruits, which are usually dark blue or black. The collected seeds should be cleaned, and the outer coat should be removed before sowing. The seeds can be sown directly in the soil or in pots filled with a well-draining soil mix. The pots should be kept in a warm and humid place until the seeds germinate. It can take up to three weeks for the seeds to germinate.
Stem Cuttings
Stem cuttings are another popular method of propagating Clerodendrum dubium plants. The stem cuttings should be taken from a healthy and mature plant. The cuttings should have at least two nodes and should be around 6 to 8 inches long. The cuttings should be propagated in a well-draining soil mix and should be kept in a warm and humid place. The cuttings should be misted regularly to keep them hydrated. It can take up to 4 to 6 weeks for the cuttings to root and develop into new plants.
Air Layering
Air layering is a propagation method that involves rooting a stem that is still attached to the mother plant. This method is useful for plants that are difficult to propagate from stem cuttings. The stem of the plant is wounded, and a rooting hormone is applied to the wound. Then the wound is wrapped with sphagnum moss and covered with plastic wrap. The roots will begin to emerge from the wound, and when they are strong enough, the new plant can be separated from the mother plant.
Division
Division is a propagation method that involves dividing the roots of a mature plant into smaller sections. Each section should have enough roots to support a new plant. The sections should be planted in a well-draining soil mix, and they should be kept in a warm and humid place until they establish new roots. This method is useful for plants that have outgrown their pot or garden space.
Overall, Clerodendrum dubium De Wild. is an easy plant to propagate, and it can be propagated through various methods. With proper care and attention, the plants will develop into beautiful specimens that will enhance the beauty of any garden.

Diseases
Fungal leaf spots are one of the most common diseases that affect the Clerodendrum dubium De Wild. This disease appears as circular or angular spots that are colored brown or black, surrounded by a yellow halo. In severe cases, leaves can turn yellow and fall off.
To prevent or manage fungal leaf spots, you must ensure that your plant has enough air circulation and that you do not overwater it. Remove infected leaves and dispose of them appropriately. Apply a fungicide if necessary, following the instructions on its label.
Another common disease affecting the Clerodendrum dubium De Wild. is powdery mildew, a fungal disease that creates a powdery white film on the leaves. This disease can make the plant unsightly but is not lethal.
To manage powdery mildew, avoid humid conditions, and make sure the plant has good air circulation. Prune any weak or infected parts and dispose of them well. Consider applying a fungicide, following the instructions provided.
Pests
Spider mites and scale insects are common pests affecting Clerodendrum dubium De Wild. Spider mites are tiny pests that suck the plant's sap, causing leaves to dry and turn yellow.
To manage spider mites, use a strong stream of water to hose off the insects regularly. You can also introduce predatory mites such as Phytoseiulus persimilis or Neoseiulus fallacis to control their population. Chemical insecticides may be used as a more extreme option.
Scale insects, on the other hand, are small, immobile insects that suck the plant's sap, leaving behind a sticky residue known as honeydew, which can attract other pests as well as fungi.
To manage scale insects, you can scrub them off with a soft-bristled brush dipped in soapy water. Apply insecticidal soap or horticultural oil to the leaves, following the instructions on the label. You can also use systemic insecticides, but be careful not to harm pollinators such as bees.
Regular observation and preventive measures are crucial to managing pests and diseases affecting Clerodendrum dubium De Wild., and other plants in general.
