Light Requirements
Oxyanthus latifolius Sond. prefers bright, indirect light. It can tolerate low light, but growth may slow down, and plants may become leggy. It is best to place the plant near a south- or east-facing window but avoid direct sunlight, which can scorch the leaves. If natural light is insufficient, supplemental artificial light can be used.
Temperature Requirements
Oxyanthus latifolius Sond. thrives in warm temperatures between 18°C and 27°C. It can tolerate slightly cooler conditions but not below 13°C. Rapid temperature fluctuations can damage the plant, so it is best to keep it away from drafty windows or doors. In winter, it is crucial to protect the plant from cold drafts and fluctuating temperatures.
Soil Requirements
Oxyanthus latifolius Sond. prefers well-draining, porous, and slightly acidic soil. A quality potting mix consisting of equal parts perlite, peat moss, and vermiculite will provide excellent drainage while retaining some moisture. It is important not to let the soil dry out completely, as this can cause the leaves to wilt and drop. On the other hand, waterlogged soil can lead to root rot, so be careful not to overwater.
Cultivation
Oxyanthus latifolius Sond. is a tropical plant that thrives in warm climates. It is commonly grown in pots or hanging baskets, making it a perfect ornamental plant for both indoor and outdoor spaces. The plant requires well-draining soil that is rich in organic matter. For successful cultivation, ensure that the soil pH is between 5.5 and 7.5.
When planting the Oxyanthus latifolius Sond., ensure that the roots are not damaged. Plant the stem at the same depth it was in its original pot. Regularly replenish the soil to help the plant establish a robust root system to support its vibrant foliage.
Watering Needs
The Oxyanthus latifolius Sond. requires moist but well-drained soil. During the growing season, water the plant twice a week or when the top inch of soil feels dry to the touch. The frequency of watering should be reduced in winter. Overwatering may lead to root rot, hence avoid waterlogging the soil.
Fertilization
Fertilize your Oxyanthus latifolius Sond.with a balanced liquid fertilizer every two weeks during the active growing season. Use a specially formulated fertilizer rich in essential nutrients such as nitrogen, potassium, and phosphorus. Over-fertilization may lead to leaf drop or burnt roots.
Pruning
Oxyanthus latifolius Sond. requires regular pruning to maintain its aesthetic appeal and growth pattern. Prune back overgrown and leggy shoots to encourage bushier growth and more extensive blooming. Deadhead the spent flowers to stimulate more blooms. Use sterilized pruning shears to minimize the chances of spreading diseases.
Propagation of Oxyanthus latifolius Sond.
Oxyanthus latifolius Sond. can be propagated through seeds or stem cuttings.

Propagation from Stem Cuttings
Stem cuttings can be taken from healthy, mature plants in the spring or summer. The cuttings should be approximately 10cm in length and should have at least two nodes.
The cuttings should be dipped in a rooting hormone and planted in a well-draining potting mix. The container should be covered with a plastic bag to increase humidity and kept in a shaded area.
Rooting should occur within 4-6 weeks and the new plants can be potted up in individual containers and gradually acclimatized to the outside environment.
