Water regularly, keeping the soil consistently moist but not waterlogged. Allow the top few centimeters of soil to dry out between waterings, especially during dry spells.

Reduce watering slightly in cooler weather or if the plant is not actively growing. Good drainage is crucial to prevent root rot.

Pruning is generally not required for Ipomoea batatas, as it is grown for its tubers. However, if the vines become excessively long or unruly, you can trim them back to maintain a manageable size and shape.

This can also encourage bushier growth and potentially more tuber development.

Sweet potatoes are typically propagated vegetatively from 'slips', which are sprouts grown from mature tubers. Place tubers in a warm, moist environment until sprouts emerge.

Once the sprouts are 15-20 cm long, carefully detach them, remove the lower leaves, and plant them directly into the soil or root them in water.

Repotting is not a common practice for sweet potatoes grown as annuals for tuber harvest.

If growing for ornamental purposes or over-wintering, repot into a larger container when the plant becomes root-bound, typically in spring before active growth begins. Use a well-draining potting mix.
