Water Aloysia barbata thoroughly when the top 2-3 cm of soil feels dry to the touch. Allow excess water to drain away completely. Avoid overwatering, as this can lead to root rot.

Reduce watering frequency during cooler winter months.

Prune Aloysia barbata in early spring before new growth begins to shape the plant and remove any dead or damaged branches. Lightly trim throughout the growing season to maintain desired size and encourage bushier growth.

Avoid heavy pruning which can stress the plant.

Propagate Aloysia barbata from semi-hardwood cuttings taken in late summer or early autumn. Insert cuttings into a well-draining potting mix.

Keep the cuttings moist and in a warm, bright location with good air circulation. Rooting typically occurs within several weeks.

Repot Aloysia barbata every 2-3 years, or when it becomes root-bound. Spring is the ideal time for repotting. Choose a pot that is only slightly larger than the current one.

Use a well-draining potting mix, such as a cactus or succulent blend.
