Light Requirements
Ruellia togoensis (Lindau) Heine prefers a bright, indirect or dappled sunlight for proper growth. It can also grow well under partial shade conditions, receiving about 4 to 6 hours of direct sunlight daily. However, too much direct sunlight can lead to scorching of the leaves and stunted growth. Placement near a south-facing window with sheer curtains or an east-facing window with bright, indirect light is recommended.
Temperature Requirements
The plant requires a warm temperature, and the ideal range for its growth is between 20°C to 30°C (68°F to 86°F). Temperatures below 10°C (50°F) can harm the plant and cause it to wilt and die. It is recommended to avoid exposing Ruellia togoensis to sudden temperature fluctuations, such as drafts from air conditioning units or heaters.
Soil Requirements
The plant prefers a rich, well-draining soil with a slightly acidic to neutral pH range of 6.1 to 7.5. It can grow well in various soil types, including loamy, sandy or clay soils, as long as they are adequately drained. Adding organic matter, such as compost or peat moss, can improve soil structure, help retain moisture, and provide nutrients, promoting more robust growth.
Cultivation
Ruellia togoensis is a tropical plant that ideally thrives in warm temperatures. It requires well-drained soils that are rich in nutrients. The plant can be grown in containers or in the garden. To cultivate Ruellia togoensis, the plant should be propagated by stem cuttings and planted in moist soil. It requires sunlight, but not direct sunlight, meaning that it should be recommended to plant the Ruellia togoensis in a place with partial shade.
Watering Needs
The Ruellia togoensis plant prefers moist soil. It should not be overwatered as this can lead to the plant being waterlogged and eventually dying. Watering should be done frequently in small amounts to ensure that the soil remains moist but not waterlogged. It is advisable to check the soil moisture level before watering to avoid overwatering.
Fertilization
Fertilizing the Ruellia togoensis plant is essential for its optimal growth and health. It is recommended to use a balanced liquid fertilizer every two weeks during the growing season to provide nutrients that the plant needs. Over-fertilization should be avoided as it can cause harm to the plant by damaging its roots and leading to excessive foliage growth at the expense of flower production.
Pruning
Pruning is required to maintain the Ruellia togoensis plant in the desired shape and size. It should be done in late winter or early spring before the plant begins to grow. Dead or damaged stems and leaves should be removed, and any overgrowth should be trimmed to promote better branching and flowering. The plant should be pruned conservatively and should not exceed a third of its original size to avoid stunting its growth.
Propagation of Ruellia togoensis
Ruellia togoensis is propagated mainly by seeds and cuttings.
Propagation by Seeds
The propagation of Ruellia togoensis through seeds is fairly easy. The flowers used for propagation should have already matured before harvesting the seeds. Once the flowers start to wilt, they should be removed carefully and stored in a dry place. After a few days, the seeds can be collected and sown in a seedbed or directly in the field. The ideal time for sowing is during the rainy season when the soil is moist. The seeds should be sown at a maximum depth of 2 cm. Within 1 to 2 weeks, the seeds will germinate, and the seedlings will start to grow.
Propagation by Cuttings
Propagation of Ruellia togoensis through cuttings is also possible. Cuttings should be taken from the healthy stems of the plant, preferably in the rainy season when the plant is actively growing. The cuttings should be about 10 to 15 cm long and should have at least one node. The lower leaves should be removed, leaving only the top 2 to 3 leaves intact. The cuttings should then be dipped in a rooting hormone and planted in a well-draining rooting medium, making sure that at least one node is buried in the medium. Keep the cuttings moist and in a shaded area until they have established roots.
Both propagation methods of Ruellia togoensis are relatively easy and can yield healthy and viable plants.
