Adesmia ameghinoi prefers consistently moist soil during its growing season. Water thoroughly when the top centimeter of soil feels dry.

Reduce watering significantly in winter to prevent root rot, allowing the soil to dry out more between waterings. Avoid waterlogged conditions.

Prune Adesmia ameghinoi in late winter or early spring before new growth begins. Remove any dead, damaged, or crossing branches to maintain plant health and shape.

Light trimming can encourage bushier growth and more abundant flowering. Avoid heavy pruning.

Propagation is typically done by seeds sown in spring. Stratify seeds by exposing them to a period of cold, moist conditions for 4-6 weeks before sowing.

Alternatively, semi-hardwood cuttings can be taken in summer and rooted in a well-draining medium.

Repot Adesmia ameghinoi every 2-3 years or when the plant becomes root-bound. Use a well-draining potting mix, such as a blend of peat moss, perlite, and compost. Repot in early spring before active growth commences.

Choose a pot slightly larger than the current one.
