Water Tridax bicolor moderately, allowing the soil to dry out slightly between waterings. Avoid overwatering, as this can lead to root rot.

In hotter, drier conditions, more frequent watering may be necessary, but always check soil moisture before adding more water to ensure optimal conditions.

Pruning Tridax bicolor is beneficial for maintaining a tidy appearance and encouraging bushier growth and more blooms. Deadheading spent flowers regularly prevents self-seeding and promotes continuous flowering.

Light pruning of overgrown stems can be done in spring to shape the plant.

Tridax bicolor is easily propagated by seeds sown in spring or early summer. It can also be propagated from cuttings taken in late spring or early summer.

Seeds germinate readily in well-draining soil under warm conditions, making it a simple plant to propagate.

Repot Tridax bicolor when it becomes root-bound, typically every 1-2 years. Spring is the ideal time for repotting.

Choose a pot that is slightly larger than the current one and use a well-draining potting mix to ensure good aeration for the roots and prevent waterlogging.
