Emilia discifolia prefers consistent moisture but dislikes waterlogged soil. Water thoroughly when the top 2-3 cm of soil feels dry.

Reduce watering slightly during cooler months, but do not allow the soil to dry out completely. Ensure good drainage to prevent root rot.

Pinch back the tips of young plants to encourage bushier growth. Deadhead spent flowers regularly to promote continuous blooming and maintain a tidy appearance. Prune any yellowing or damaged leaves as needed.

Hard pruning is generally not required unless reshaping is necessary.

Emilia discifolia is easily propagated from seed sown in spring. Sow seeds on the surface of a well-draining seed-starting mix and keep moist and warm.

Seedlings can be transplanted into individual pots once they are large enough to handle and gradually acclimatized outdoors.

Repot young plants annually in spring into a slightly larger container. Mature plants can be repotted every two to three years or when they become root-bound.

Use a well-draining potting mix, such as a blend of peat moss and perlite, to ensure adequate aeration and drainage.
