Oldenlandia coccinea typically requires bright, indirect light to thrive. While it can tolerate some direct sunlight, excessive exposure to the sun may cause leaf scorching. It is ideal to place the plant near an east-facing window or provide artificial grow lights for about 12-16 hours per day.
Temperature Requirements
The ideal temperature range for Oldenlandia coccinea is between 18-27°C. It prefers warm environments and cannot tolerate frost or temperatures below 10°C. It is best to keep the plant away from cold drafts and air conditioning units.
Soil Requirements
Oldenlandia coccinea prefers well-draining, rich soil. A recommended potting mix consists of equal parts peat moss, perlite, and vermiculite. The soil should be kept moist but not waterlogged as this can result in root rot. Adding organic matter, such as compost, to the soil can also help retain moisture.
Cultivation Methods
Oldenlandia coccinea, commonly known as redstar, thrives in warm tropical and subtropical climates. It can be grown both indoors and outdoors and prefers bright, indirect sunlight. The plant requires well-drained soil that is rich in organic matter and slightly acidic in nature, with a pH range between 6.0 and 7.5. Avoid soil that is too moist or too dry.
Propagation can be done through seedlings or stem cuttings, planted in prepared soil before the onset of the rainy season. Transplanting should be done periodicaly to give the plant enough space to grow.
Watering Needs
Oldenlandia coccinea prefers consistent moisture in soil, but not too much water that will lead to waterlogging. Allow the topsoil to dry before watering again. Overwatering can lead to root rot, which can be fatal to the plant. It is recommended to water the plant in the morning hours, and avoid wetting the leaves to prevent fungal growth.
Fertilization
The plant requires regular feeding with a balanced fertilizer during the growing season, preferably every two weeks to promote optimal growth. Avoid using too much fertilizer, which can lead to quick growth but weaken the plant and make it more susceptible to diseases.
Pruning
Pruning of Oldenlandia coccinea can be done to shape the plant and promote bushiness. Pruning can be done anytime to get rid of leggy and old foliage. However, the best time to prune the plant is during the early spring before the onset of the rainy season. Prune to remove up to 1/3 of the plant's overall size to create a fuller appearance.
Propagation of Oldenlandia coccinea (Royle) Hook.f.
Oldenlandia coccinea (Royle) Hook.f. is commonly known as Scarlet Madder or Indian Madder, and it belongs to the Rubiaceae family. This plant is native to the Himalayan region and widely distributed in Southern Asia, Eastern Africa, and Australia. It is a herbaceous plant that grows up to 60 cm high and produces clusters of small red or pink flowers. Propagation of Oldenlandia coccinea can be done through different methods, considering the plant's growing conditions and natural habitat.
Propagation through Seeds
The most common method to propagate Oldenlandia coccinea is through seeds. Collect the seeds when the capsule of the flower gets dry and brittle. Sow the seeds in a well-drained potting mix or topsoil with compost. Cover the seeds with a thin layer of soil and lightly water. Maintain the soil moisture level and place the pot in a bright, warm location. The seeds will germinate in 2-3 weeks, and once they grow to a few centimeters tall, you can transplant them to the desired location or container.
Propagation through Stem Cuttings
Propagation through stem cuttings is another way to propagate Oldenlandia coccinea. Take a healthy stem cutting of about 10 cm length, preferably from the tip of the plant. Remove the leaves from the lower part of the cutting and dip it in water or rooting hormone powder. Plant the cutting in a potting mix or a mixture of peat and sand. Water the cutting and cover it with a plastic bag or a transparent container to trap the moisture. Place the container in a bright, warm location, and keep the soil moist. The cutting will develop roots in 2-3 weeks, and then you can transplant it to the desired location.
Propagation through Division
Oldenlandia coccinea can also be propagated by division during the spring season. Dig up the plant's whole root ball and check if it has multiple shoots or crowns. Carefully separate the shoots and roots from each other and plant them in individual pots. Make sure to water the newly planted divisions and place them in a suitable location with enough light and humidity. Once the divisions develop roots and new growth, repot them in a new container or desired location.
Conclusion
Propagation of Oldenlandia coccinea through seeds, stem cuttings, and division is relatively easy and straightforward. The selection of propagation method ultimately depends on the availability of plant material, growing conditions, and time of year. Using the above methods, gardeners and plant enthusiasts can grow this beautiful plant and enjoy its lovely blooms.
