Water Tridax procumbens regularly, especially during establishment and dry periods. Allow the soil to dry slightly between waterings. Overwatering can lead to root rot, so ensure good drainage.

In hot climates, more frequent watering may be necessary.

Pruning is mainly for aesthetic purposes and to encourage bushier growth. Deadhead spent flowers regularly to prevent self-seeding and to promote continuous blooming.

Trim back overgrown stems to maintain a desired shape and size, ideally in spring or after flowering.

Tridax procumbens is easily propagated by seeds, which are readily produced and dispersed by wind. It can also be propagated by stem cuttings taken during the growing season.

Division of established clumps is another effective method for propagation.

Repotting is typically not a major concern for Tridax procumbens, as it is often grown as an annual or groundcover. If grown in containers and it becomes root-bound, repot in spring into a slightly larger pot with fresh, well-draining potting mix.
