Ellisia prefers consistently moist soil. Water thoroughly when the top centimeter of soil feels dry to the touch. Avoid allowing the soil to completely dry out, as this can stress the plant.

Ensure good drainage to prevent waterlogged roots, which can lead to root rot.

Pruning is typically minimal for Ellisia. Pinch back the tips of young plants to encourage bushier growth. Remove any yellowing or dead foliage as needed to maintain a tidy appearance.

Significant pruning is usually not necessary as it is a relatively short-lived plant.

Ellisia is easily propagated from seed. Sow seeds indoors in late winter or early spring, or directly outdoors after the last frost. The seeds germinate readily in moist, well-draining soil.

It can also self-seed readily in the garden.

Repotting is generally not a significant concern for Ellisia, as it is often grown as an annual or short-lived perennial.

If growing in a container and it becomes root-bound, repot into a slightly larger container in the spring. Use a well-draining potting mix.
