Light Requirements
Coleus trichophorus Briq. generally grows well in partial shade, although it can also tolerate full sun in cooler climates. In areas with hotter and drier climates, it is best to provide some shade during the hottest part of the day to prevent the plant from getting too much direct sunlight.
Temperature Requirements
For optimal growth, Coleus trichophorus Briq. prefers temperatures between 60°F and 75°F. However, it can tolerate temperatures as low as 50°F and as high as 90°F. It is important to note that during extremely high or low temperatures, the growth of Coleus trichophorus Briq. can be significantly affected, and extra care must be taken to protect the plant.
Soil Requirements
Coleus trichophorus Briq. prefers well-drained soil that is rich in organic matter. The recommended pH range is between 6.0 and 7.5. It is important to avoid waterlogged soil as this can lead to root rot. Adding compost or other organic matter to the soil can improve the drainage and aeration of the soil, ensuring optimal growth conditions for the plant.
Cultivation Methods for Coleus trichophorus Briq.
Coleus trichophorus Briq. is a tropical plant and needs to be grown in warm temperatures. The plant should be kept in a bright area that receives filtered sunlight for best growth results.
The ideal temperature range for Coleus trichophorus Briq. is between 18 – 26°C (64 – 79°F). The plant should be kept away from cold and drafty environments as it is very sensitive to cold weather.
Watering Needs for Coleus trichophorus Briq.
The watering needs of Coleus trichophorus Briq. are moderate, and the plant should be watered when the soil feels dry. Over-watering can lead to root rot, which can cause the demise of the plant. However, under-watering should also be avoided as it can lead to the wilting of the plant.

Propagation of Coleus trichophorus Briq.
Coleus trichophorus Briq. plant can be propagated through both vegetative and sexual means. These propagation methods yield healthy and genetically identical plants.
Propagation through stem cuttings
Stem cuttings are the most common method of propagation for the Coleus trichophorus Briq. plant. The cuttings should be taken from the tip of a healthy and mature plant. A cutting with three to four nodes is ideal. Remove the lower leaves and dip the cut end of the stem in rooting hormone before planting. Plant the cutting in a well-draining growing medium, keep it moist, and place it in a warm, bright, and humid area. In about two to four weeks, roots will develop, and the plant can be transplanted to a larger pot or garden bed.
Propagation through division
Dividing Coleus trichophorus Briq. is another way of propagating the plant. This method works best for more mature plants and involves separating the plant into smaller sections, each with its own root system. Dig up the plant and gently separate the sections before replanting in a new location. Ensure to water the plant thoroughly after division.
Propagation through seeds
Coleus trichophorus Briq. can also be propagated through seeds. Collect the seeds when the flowers fade and the seeds turn brown. Sow the seeds in a growing medium and cover them lightly. Keep the soil moist and warm by covering it with a plastic wrap. Germination may take between 1-3 weeks, depending on the temperature and humidity. When the seedlings are large enough, transplant them to their permanent location.
With proper care and attention, Coleus trichophorus Briq. propagates easily. Choose the propagation method that works best for your situation and enjoy healthy and beautiful plants in no time.
