If you want to propagate Plectranthus herbaceus Schweinf., there are several methods you can use, including:
Seeds
The easiest and most common method of propagation used for this plant is through seeds. The seeds of Plectranthus herbaceus Schweinf. can be sown directly into the soil or started indoors. If starting indoors, you can use a seed tray filled with seed-starting soil. Plant the seeds at a depth of a quarter of an inch to half an inch and keep them moist. Germination typically takes around 10-14 days, depending on the temperature and soil moisture. Once the seedlings establish, transplant them into individual pots and then into the garden once they are large enough.
Softwood cuttings
Another method of propagation is through softwood cuttings, which involves taking cuttings from the end of the plant’s soft, new growth. Cut a piece of stem around 3 to 4 inches long, just below a set of leaves. Remove the leaves from the bottom half of the stem and dip the cut end in rooting hormone. Plant these cuttings in a pot filled with well-draining soil and keep the soil moist. After a few weeks, the cuttings should develop roots. You can then transplant them into a larger pot or into your garden.
Semi-hardwood cuttings
Propagating Plectranthus herbaceus Schweinf. by semi-hardwood cuttings is also possible. Semi-hardwood cuttings are taken from slightly older growth compared to softwood cuttings. Take a 4- to 6-inch cutting from the tip of a semi-hardwood stem, making sure to remove any flowers or buds. Remove the leaves from the bottom half of the stem, and dip the cut end in rooting hormone. Plant the cutting in a well-draining pot filled with soil, and keep the soil moist. After a few weeks, the cutting should develop roots, and you can transplant it into a larger pot or into your garden.

To manage powdery mildew, remove and destroy all infected plant parts, increase air circulation by pruning overgrown branches, and use fungicides.
2. Leaf spot
Leaf spot is a fungal disease that causes circular or irregular spots on the leaves, which may be brown, black, or gray. As the disease progresses, the spots may grow in size, causing the leaves to wither and drop prematurely. The management of leaf spot involves removing and destroying affected plant parts and using fungicides.
Common Pests of Plectranthus herbaceus Schweinf.
Pests that commonly affect P. herbaceous include:
1. Spider mites
Spider mites are tiny arachnids that suck sap from the leaves of the plants, causing them to turn yellow and drop prematurely. To manage spider mites, maintain adequate humidity by spraying water on the leaves, use insecticidal soap, or neem oil.
2. Mealybugs
Mealybugs are soft-bodied insects that suck sap from the plant and excrete a sticky substance, which can lead to the development of sooty mold. The management of mealybugs involves physically removing them from the plant, using insecticidal soap and neem oil.
Overall, the management of pests and diseases in P. herbaceous involves maintaining good cultural practices such as proper watering and fertilizer application to enhance the plant's vigor and resistance to pests and diseases. Additionally, regular inspection of the plants for signs of diseases and pests is crucial in catching the problem early and managing them effectively.
