Water consistently to keep the soil evenly moist, but not waterlogged. Allow the top few centimeters of soil to dry out slightly between waterings, especially during warmer months.

Reduce watering frequency in cooler periods to prevent root rot.

Pinch back young plants to encourage bushier growth. Deadhead spent flowers regularly to promote continuous blooming.

Light pruning can be done in late winter or early spring to shape the plant and remove any dead or damaged stems.

Propagate Angelonia arguta from stem cuttings taken in spring or early summer. Dip the cut ends in rooting hormone and plant them in a well-draining potting mix.

Keep them consistently moist and warm in a bright location until roots form.

Repot young plants annually or when they become root-bound, typically in early spring. Choose a pot that is only slightly larger than the current one.

Use a well-draining potting mix, ideally with added perlite or sand for improved aeration.
