Temperature Requirements
The plant prefers warm temperatures ranging between 26°C to 32°C for optimum growth. It is not tolerant to low temperatures and will stop growing or die if exposed to temperatures lower than 15°C for extended periods. If grown indoors, adequate heating must be ensured to maintain the required temperature range.
Soil Requirements
Digitaria trichopodia Stent grows best in well-drained soils with rich organic nutrients. The soil should have a pH between 5.5 and 7.5. It prefers moist soils and cannot tolerate dry conditions for prolonged periods. If growing the plant in pots, ensure the pot has adequate drainage holes to prevent waterlogging.
Cultivation Methods
The plant Digitaria trichopodia Stent can be grown in either full sun or partial shade and can adjust well to a variety of soils, from clay loam to sandy loam. It is best to plant during the spring or early summer when the weather is warm and the soil has thawed from the winter. Plant the seeds about 1/8 to 1/4 inch deep and space them apart about 6 inches.
Watering Needs
The Digitaria trichopodia Stent thrives in well-drained soil, so it is important not to overwater the plant. When watering, ensure that the soil is moist, but not waterlogged. During periods of drought, it is recommended to water the plant once a week, especially if the soil is sandy.
Fertilization
During the growing season, it is recommended to fertilize the Digitaria trichopodia Stent with a balanced, slow-release fertilizer once a month. Too much fertilizer can cause excessive growth, which can weaken the plant and make it more susceptible to disease and pests.
Pruning

Propagation of Digitaria trichopodia Stent
Digitaria trichopodia Stent can be propagated either through seeds or vegetatively.
Seeds
The seeds of Digitaria trichopodia Stent can be collected from the matured plants and sown during the rainy season. The seeds require moisture and warm temperature to germinate. The recommended method is to sow the seeds in well-prepared seedbeds, lightly cover them with soil, and water them regularly to maintain moisture. Germination of the seeds typically occurs within 10-14 days. Once the seedlings are established, they can be transplanted to their permanent locations.
Vegetative Propagation
Digitaria trichopodia Stent can also be propagated vegetatively through stem cuttings. This method involves selecting healthy stems of about 15-20 cm in length and making clean cuts below a node. The cuttings should be planted in well-drained soil with adequate moisture and placed in a shaded area to facilitate root formation. When the cuttings have developed roots and new shoots, they can be transplanted to their permanent locations.
