Light Requirements
Fuirena pubescens var. abbreviata requires full sun exposure for optimal growth. The plant can tolerate partial shade, but it may affect its growth rate and flowering. It is recommended to place the plant in a location that receives at least 6 hours of direct sunlight daily.
Temperature Requirements
The species is known to grow in tropical and subtropical regions, but it can also tolerate temperate climates. It grows best in temperatures ranging from 20°C to 30°C (68°F to 86°F). Temperatures below 10°C (50°F) or above 35°C (95°F) can harm the plant and stunt its growth.
Soil Requirements
Fuirena pubescens var. abbreviata prefers well-drained, moist soils with a pH range between 5.5 and 7.5. It can tolerate slightly acidic or alkaline soils, but extreme pH levels can damage the roots. The plant can grow in a variety of soil types, including sandy or clay soils. However, it prefers soils that are rich in organic matter and can retain moisture.
Cultivation Methods
Fuirena pubescens (Poir.) Kunth var. abbreviata Lye can be cultivated in a variety of soil types, including sandy and clay soils. The plant prefers moist soils but can also tolerate drought conditions. It is recommended to plant the seeds in early spring or late fall, where the temperatures are mild.
Watering Needs
The plant requires regular watering, especially during the growing season. The soil should be kept moist but not waterlogged. If grown in sandy soil, it may need more frequent watering than clay soil. It is important to avoid watering the foliage as it can lead to disease and fungal infections.
Fertilization
Fuirena pubescens (Poir.) Kunth var. abbreviata Lye does not require frequent fertilization. However, a slow-release fertilizer can be added to the soil at the time of planting. Alternatively, a liquid fertilizer can be used during the growing season to promote growth and development.
Pruning
The plant requires minimal pruning. Dead or yellow leaves can be removed, and the flowers can be cut back after they have finished blooming. It is recommended to prune the plant in late winter or early spring to promote vigorous growth in the upcoming season.
Propagation of Fuirena pubescens (Poir.) Kunth var. abbreviata Lye
Fuirena pubescens (Poir.) Kunth var. abbreviata Lye can be propagated by seeds, rhizomes, and cuttings.
Propagation by seeds
The seeds of Fuirena pubescens (Poir.) Kunth var. abbreviata Lye are small and can be sown directly into a seedbed or in containers filled with a well-draining potting mix. Germination usually occurs within two weeks. The seedlings can be transplanted to their permanent location once they have developed a strong root system.
Propagation by rhizomes
Fuirena pubescens (Poir.) Kunth var. abbreviata Lye can also be propagated by dividing the rhizomes. The rhizomes should be dug up, and the healthy, firm portions should be divided into sections, each containing at least one growing point. These sections can be replanted immediately in well-draining soil and should be kept moist until they become established.
Propagation by cuttings
Propagation by cuttings is possible but not commonly practiced for Fuirena pubescens (Poir.) Kunth var. abbreviata Lye. The cuttings should be taken from the tips of the stems and should be about 10-15 cm long. They should be planted in a well-draining soil mixture and kept moist until they start rooting.
