Water Sphaeralcea bonariensis thoroughly when the top 2-3 cm of soil feels dry. Avoid waterlogging, as this can lead to root rot. During prolonged dry spells, provide supplemental watering.

Reduce watering in winter when the plant is less active.

Prune Sphaeralcea bonariensis in late winter or early spring before new growth begins. Remove any dead, damaged, or crossing stems. Cutting back by about one-third encourages bushier growth and more abundant flowering.

Deadheading spent flowers can promote further blooming.

Sphaeralcea bonariensis can be propagated by seeds sown in spring, or by semi-hardwood cuttings taken in summer. Seeds may require stratification.

Cuttings should be rooted in a well-draining medium in a warm environment with high humidity.

Repot Sphaeralcea bonariensis every 2-3 years, or when it becomes root-bound. Spring is the ideal time for repotting. Use a well-draining potting mix, such as a cactus or succulent blend.

Ensure the new pot has adequate drainage holes.
