Light Requirements
The Indigofera perplexa N.E.Br. plant requires full or partial sunlight to grow. It thrives in an environment where it can receive at least six hours of direct sunlight. When planted indoors, make sure to place the plant in an area that gets bright, indirect light.
Temperature Requirements
The Indigofera perplexa N.E.Br. plant grows ideally in temperatures between 20°C to 28°C. Nevertheless, the plant can tolerate temperatures as low as 10°C and high as 35°C but may not thrive in extreme temperatures.
Soil Requirements
The Indigofera perplexa N.E.Br. plant requires well-draining, slightly acidic soil with a pH range of 6.0 to 7.5. Add some compost to the soil to improve drainage and fertility. The plant requires moderate moisture, and it is best to water only when the soil dries out, to avoid waterlogging the roots.
Cultivation
Indigofera perplexa N.E.Br. thrives in well-drained soil under full sunlight exposure. As a frost-sensitive plant, the minimum temperature required for cultivation should be no lower than 10°C. Propagation can occur both by seeds and cuttings; however, seeds can take longer to germinate. It is advisable to sow the seeds in seedbeds or directly in the planting location. In contrast, cuttings can be rooted under high humidity and mist.
Watering Needs
Indigofera perplexa N.E.Br. requires moderate watering, especially during the hot and dry season. The water must penetrate through the soil, reaching the plant's roots. However, the soil should not be soaked because excessive water in the soil can lead to root rot and may also attract pests and diseases. The frequency of watering is determined by factors such as the plant's age, size of the plant, and environmental conditions.
Fertilization
Indigofera perplexa N.E.Br. is not a heavy feeder. However, when planting, it is advisable to incorporate compost or well-rotted manure into the soil. This soil amendment helps to improve soil structure, enrich the soil with nutrients, and enhance soil moisture retention. In addition, a general-purpose fertilizer can be used during the plant's growing season to boost its growth and health. Once the plant becomes established and starts showing vigorous growth, reduce the frequency of fertilization.
Pruning
Pruning Indigofera perplexa N.E.Br. can stimulate new growth and maintain the plant's shape. Pruning should be done when the plant is dormant or during its growing season. To encourage a bushy habit, prune the tips of the plant's branches. Deadheading, which involves removing the spent flowers, can prolong the plant's flowering period. The plant's overall shape can also be maintained by removing any damaged or diseased branches and stems.
