Water regularly during its first growing season to establish a deep root system. Once established, White rosinweed is drought-tolerant.

Water only during prolonged dry spells, allowing the soil to dry out completely between waterings to prevent root rot.

Deadhead spent flowers to encourage more blooms and prevent self-seeding if not desired. In late fall or early spring, cut back the old, dried foliage to about 10-15 cm from the ground to promote new growth and maintain a tidy appearance.

White rosinweed can be propagated by seeds sown in early spring or fall. Division of established clumps in early spring is also an effective method. Ensure seeds are lightly covered and kept moist until germination.

Repotting is generally not necessary for White rosinweed as it is a perennial that thrives when left undisturbed. If growing in a container, repot in spring every 2-3 years to refresh the soil and provide more space, using a well-draining potting mix.
