Water moderately when the top inch of soil feels dry. Tephrosia purpurea is drought-tolerant once established. Avoid overwatering, as this can lead to root rot.

Reduce watering frequency during cooler, dormant periods to prevent waterlogged soil and potential fungal issues.

Prune lightly to shape the plant and remove any dead or damaged stems. This can be done in late winter or early spring before new growth begins. Pinching back young plants encourages bushier growth.

Avoid heavy pruning, as it may stress the plant.

Propagate from seeds, which germinate readily after soaking. Cuttings can also be taken from semi-hardwood in summer. Seedlings require well-draining soil and moderate watering.

Cuttings should be rooted in a moist, sandy medium and kept in a warm, bright location.

Repot only when necessary, typically every 2-3 years, when the plant becomes root-bound. Use a well-draining potting mix, such as a cactus or succulent blend.

Choose a pot that is only slightly larger than the current one to avoid excessive moisture retention.
