Oldenlandia cicendioides K.Schum. is a small shrub that is indigenous to the African continent, specifically in countries such as Angola, Botswana, Malawi, Mozambique, South Africa, Tanzania, Zambia, and Zimbabwe. The plant typically grows in bushlands, grasslands, and coastal forests.
Light Requirements
The plant thrives in areas with ample sunlight. It does not do well in areas with too much shade or low light intensity. The minimum light requirement for Oldenlandia cicendioides is about six hours of direct sunlight daily. It is, therefore, advisable to plant the herb in an area with maximum exposure to sunlight, such as open fields or areas with minimal tree cover.
Temperature Requirements
Oldenlandia cicendioides K.Schum. is well adapted to tropical and subtropical climates, and it can survive in areas with temperatures ranging from 16 to 30 degrees Celsius. The shrub grows optimally at temperatures between 20 and 25 degrees Celsius. In areas with cooler climates, it is advisable to plant the herb in a greenhouse to regulate temperature and create the necessary warm conditions.
Soil Requirements
The plant can grow in a wide range of soil types, provided that the soil has adequate drainage. The optimal soil pH ranges from 5.5 to 7.0. The shrub prefers sandy loam soil that is rich in organic matter. It is also essential to ensure that the soil is not waterlogged, as it can lead to root rot and stunted growth of the plant. In areas with heavy soils, it is advisable to add sand, peat, or perlite to improve drainage and aeration.
Cultivation
Oldenlandia cicendioides K.Schum. is native to tropical regions of Africa and prefers warm temperatures and high humidity. It can be grown both indoors and outdoors in areas with a similar climate.
It is recommended to plant Oldenlandia cicendioides K.Schum. in well-draining soil with a slightly acidic pH level of 6.0 to 6.5. It prefers partial shade and should be protected from hot and direct sunlight.
Propagation can be done through stem cuttings or division of the plant.
Watering Needs
Oldenlandia cicendioides K.Schum. requires consistent moisture but does not tolerate waterlogging. Water should be applied when the top inch of soil is dry to the touch. Avoid letting the soil dry out completely.
During the growing season, it is recommended to water the plant more frequently, but reduce watering during the dormant season.
Fertilization
Oldenlandia cicendioides K.Schum. benefits from regular fertilization during the growing season. Use a balanced, water-soluble fertilizer every two weeks. Avoid over-fertilizing, as this can lead to root burn and reduced growth.
Pruning
Regular pruning is recommended to encourage branching and maintain a compact shape. Prune the plant after it has finished flowering and remove any dead or diseased leaves. Oldenlandia cicendioides K.Schum. responds well to pruning and can even be pinched back to promote bushier growth.
Propagation of Oldenlandia cicendioides K.Schum.
Oldenlandia cicendioides K.Schum., also known as the African Cherokee, is a perennial herb originating from Central and Southern Africa. It is a beautiful plant with white flowers, and its propagation can be achieved through different methods.
Seed Propagation
Oldenlandia cicendioides K.Schum. can be propagated through seeds. Collect seeds from a reliable source during the appropriate season, which is usually in late summer or early autumn. Soak the seeds in water for 24 hours to increase their chances of germination then sow them in well-draining soil at a depth of 1 to 2 cm. Ensure adequate water and light and keep the soil moist. Germination should occur within two to four weeks.
Cuttings Propagation
Another way to propagate Oldenlandia cicendioides K.Schum. is by cuttings. Take cuttings from the plant's stem during the growing season, which is between spring and autumn. Cut a 10 to 20 cm stem with at least three nodes and remove the leaves from the lower half. Dip the cut end in rooting hormone and plant the cuttings in well-draining soil. Ensure that the soil is moist, but not soaked. Place the cuttings in a shaded area, and they should root in three to four weeks.
Division Propagation
Oldenlandia cicendioides K.Schum. can also be propagated through division. Divide the plant during the growing season when it becomes crowded. Gently lift the plant from the soil and separate the root ball into sections, ensuring that each section has at least one stem and a portion of the root system. Repot the divided sections in well-draining soil and keep the soil moist. Place the plant in a shaded area for several weeks until the roots establish.
These propagation methods are relatively easy, and you can use any of them to propagate Oldenlandia cicendioides K.Schum. Ensure proper care after propagation, and within no time, you'll have several plants in your garden.
Disease and Pest Management for Oldenlandia cicendioides K.Schum.
