Water deeply when the top 2-3 cm of soil feels dry. Avoid waterlogging, as Jatropha curcas is drought-tolerant once established. Reduce watering significantly during the dormant season to prevent root rot.

Ensure good drainage to mimic its native arid or semi-arid conditions.

Prune to shape the plant, remove dead or diseased branches, and manage size. Pruning is best done in late winter or early spring before new growth begins.

Jatropha curcas responds well to heavy pruning, which can encourage bushier growth and more abundant flowering.

Propagate primarily through seeds, which germinate readily under warm conditions. Cuttings can also be taken from semi-hardwood or softwood, but they may root more slowly.

Ensure cuttings are taken from healthy parent plants and treated with rooting hormone.

Repot young plants annually or every two years in spring as they outgrow their containers. Mature plants can be left in their pots for longer periods, as they prefer to be slightly pot-bound.

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