Indigofera tinctoria prefers consistently moist soil but can tolerate short periods of drought once established. Water thoroughly when the top inch of soil feels dry, ensuring good drainage to prevent root rot.

Reduce watering in cooler months when growth slows.

Prune Indigofera tinctoria in late winter or early spring before new growth begins. Remove dead, damaged, or crossing branches to maintain a tidy shape and encourage bushier growth.

Light pruning can also be done after flowering to encourage a second bloom.

Propagation is best done by seeds sown in spring, either directly outdoors or started indoors a few weeks prior. Cuttings can also be taken from semi-hardwood in summer and rooted in moist, well-draining medium.

Scarifying seeds may improve germination rates.

Young plants may need repotting annually or biennially in spring as they outgrow their containers. Choose a pot one size larger with ample drainage holes. Use a well-draining potting mix.

Mature plants are relatively tolerant of being slightly root-bound.
