It is important to avoid dark corners as insufficient light may lead to stunted growth and reduced flowering.
Temperature: This species can tolerate a wide range of temperatures, although it grows best between 18°C to 27°C. Temperatures below 13°C can be harmful to the plant while temperatures above 32°C can cause the leaves to scorch. Humidity is also important, and the plant thrives in humid conditions.
Soil: Stenogyne sessilis Benth. var. hexantha Sherff prefers moist, well-drained soils with a neutral to slightly acidic pH (6.0-6.5). The soil should also be rich in organic matter and nutrients. Avoid waterlogging, as it can cause root rot. It is important to maintain the soil moisture at a proper level to encourage healthy growth.
Fertilization: This plant requires regular fertilization to maintain healthy growth. Use a balanced, complete fertilizer every 4-6 weeks during the growing season. Avoid over-fertilizing as it can lead to excessive foliage growth at the expense of flowering.
Propagation: The plant can be grown from seeds or cuttings. Seed germination can take up to 4-6 weeks, and the plant will take another 2-3 months to reach maturity. Cuttings can be taken from healthy, mature plants and rooted in a mixture of peat and sand. Ensure the cuttings are kept moist, and the growth medium should be kept at a temperature of 18°C to 24°C until rooting occurs.
