Water regularly, keeping the soil consistently moist but not waterlogged. Allow the top layer of soil to dry out slightly between waterings. Reduce watering in cooler months, as the plant's growth slows.

Ensure good drainage to prevent root rot, especially in containers.

Pruning is generally not required for Oxybasis chenopodioides, as it is a low-growing annual. If any dead or damaged stems appear, they can be removed to maintain a tidy appearance.

Pinching back the tips in early growth can encourage a bushier habit, but this is often unnecessary.

Oxybasis chenopodioides is easily propagated by seeds. Sow seeds directly outdoors in spring after the last frost, or start them indoors a few weeks prior. Seeds germinate readily in moist, well-draining soil.

It often self-seeds readily in suitable conditions.

As an annual, repotting is typically not necessary for Oxybasis chenopodioides unless it is being grown in a container and has outgrown its space. If repotting, do so in spring before active growth begins, using fresh, well-draining potting mix.
