Water Mandevilla andina thoroughly when the top 2-3 cm of soil feels dry. Avoid waterlogged conditions, which can lead to root rot.

Reduce watering slightly in cooler months, allowing the soil to dry out a bit more between waterings.

Prune Mandevilla andina in late winter or early spring before new growth begins. Remove any dead, damaged, or crossing stems. You can also trim back leggy growth to encourage a bushier habit and more blooms.

Heavy pruning can be done to manage size.

Propagate Mandevilla andina from semi-hardwood cuttings taken in summer. Select healthy stems, take 6-10 cm cuttings, remove lower leaves, and dip the cut end in rooting hormone.

Plant in a well-draining potting mix and keep moist and warm.

Repot Mandevilla andina every 1-2 years or when it becomes root-bound. Choose a pot that is slightly larger than the current one.

Use a well-draining potting mix, preferably one containing peat or coir, to retain some moisture while ensuring good drainage.
