Temperatures below 10°C or above 30°C can cause stress to the plant and reduce its growth rate.
Soil Requirements
The plant requires well-drained and moist soil that is rich in organic matter. The pH of the soil should be slightly acidic, preferably between 5.5 and 6.5. The plant can grow in a variety of soil types, such as loamy and sandy soils, but it cannot tolerate waterlogged or poorly drained soils. Adding compost or manure to the soil can improve the soil quality and provide additional nutrients to the plant.
In conclusion, providing the appropriate growth conditions, including adequate lighting, temperature, and soil quality, is essential for the healthy growth and development of Dioscoreophyllum tenerum Engl. var. fernandense (Hutch. & Dalziel) Troupin.
Cultivation
The Dioscoreophyllum tenerum Engl. var. fernandense (Hutch. & Dalziel) Troupin plant prefers a humid and warm environment with well-draining soil. It thrives in partial shade to full shade conditions. The plant can grow up to 3 meters in height and is suitable for indoor cultivation as well. It is recommended to plant the plant in pots with well-draining soil and place them in areas with indirect light to simulate partial shade
Watering needs
The plant requires constant moisture, but not waterlogged conditions. The soil should be kept moist, especially during the growing season. The frequency of watering may vary depending on the environmental conditions, pot size, and soil type. It is recommended to monitor the soil's moisture level and adjust the watering frequency to avoid overwatering or underwatering.
Fertilization
The plant requires regular fertilization from spring to fall using a balanced liquid fertilizer. It is recommended to follow the instructions on the fertilizer package for the correct dosage and frequency. Overfertilization can cause damage to the plant, so it is crucial to avoid excess application of fertilizer. Under fertilization can also hinder the plant's growth, so it is important to ensure adequate nutrient supply by regular fertilization during the growing season.
Pruning
Pruning is essential to maintain the plant's size and shape. It is recommended to carry out pruning during the dormant season to avoid disturbing the plant's growth cycle. Remove any dead or diseased branches regularly to maintain plant health. It is also important to cut back the plant's stem regularly to promote bushy growth and maintain the desired shape.
Propagation of Dioscoreophyllum tenerum Engl. var. fernandense
Dioscoreophyllum tenerum Engl. var. fernandense is a valuable medicinal plant and is propagated by seeds, cuttings, and division.
Propagation by Seeds
Propagation by seeds is the most common method. The seeds should be collected from mature fruits that have a bright red color. The collected seeds should be cleaned and soaked in water for about 24 hours to soften the seed coat. Sowing is done in a mixture of sand and humus in a ratio of 1:1. The seeds should be covered with a thin layer of soil and kept moist. Germination occurs within 6-8 weeks, and the seedlings can be transplanted into individual pots after they have developed two true leaves.
Propagation by Cuttings
Cuttings are taken from mature stems that have hardened. The cutting should be about 10 cm long and should be made just below a node. The leaves on the lower half of the cutting should be removed. The cutting should be dipped in rooting hormones to stimulate root growth. Rooting is done in a mixture of sand and humus in a ratio of 1:1. The cutting should be kept moist and warm. Rooting occurs within 6-8 weeks. Once the cutting has rooted, it can be transplanted into individual pots.
Propagation by Division
Propagation by division is done during the plant's dormant period. The plant is dug up, and the rhizomes are separated. Each section should have at least one healthy shoot and a few roots. The sections are planted in a mixture of sand and humus in a ratio of 1:1. The soil should be kept moist, and the plant should be kept in a shaded area for about two weeks to allow it to recover from transplant shock.
