Cultivation Methods
Barleria pungens L.f. var. macrophylla Nees, commonly known as Duranta, is a tropical plant that thrives in warm, humid environments. The plant can be cultivated from either seeds or cuttings. When propagated from cuttings, ensure that they are taken from healthy branches and planted in well-draining soil.
When growing from seeds, they should first be soaked in water for 24 hours before planting. Plant the seeds in a well-drained, fertile soil mix in pots or trays. The soil should be kept moist until germination occurs. Once the plants have reached a height of 4-6 inches, they can be transplanted into larger pots or directly into the ground.
Watering Needs
Barleria pungens L.f. var. macrophylla Nees requires regular watering to maintain healthy growth. During the growing season, it is advisable to water the plant at least twice a week. However, in the winter months, reduce the frequency of watering to avoid waterlogging. Keep the soil consistently moist, but not waterlogged.
Fertilization
To encourage healthy growth, Barleria pungens L.f. var. macrophylla Nees requires regular fertilization. Use a slow-release fertilizer that is rich in nitrogen, phosphorus, and potassium. Apply the fertilizer every six weeks during the growing season. Be careful not to over-fertilize as this can cause root burn, leading to stunted plant growth.
Pruning
Barleria pungens L.f. var. macrophylla Nees requires minimal pruning to maintain healthy growth. Prune annual growth to encourage a bushy habit and remove any damaged or diseased branches. Pruning should be done at the end of the growing season to avoid over-stimulating growth during winter.
