Water Amphilophium aschersonii regularly, ensuring the soil remains consistently moist but not waterlogged. Allow the top few centimeters of soil to dry out between waterings, especially during warmer months.

Reduce watering in winter when the plant's growth slows.

Prune Amphilophium aschersonii after flowering to maintain its shape and size, and to encourage bushier growth. Remove any dead, damaged, or crossing branches.

Hard pruning can be done in late winter or early spring before new growth begins.

Propagate Amphilophium aschersonii from semi-hardwood cuttings taken in summer. Select healthy, vigorous stems and take cuttings of about 10-15 cm.

Dip the cut end in rooting hormone and plant in a well-draining potting mix. Keep moist and warm.

Repot Amphilophium aschersonii every 2-3 years, or when it becomes root-bound. Use a well-draining potting mix. Choose a pot that is slightly larger than the current one.

Repot in spring, just as new growth appears, to minimize transplant shock.
