Water Crotalaria aculeata regularly when the top 2-3 cm of soil feel dry. Avoid waterlogging, as this can lead to root rot. Reduce watering frequency during cooler months when the plant's growth slows down significantly.

Ensure good drainage in the pot.

Prune Crotalaria aculeata to maintain shape and encourage bushier growth. Lightly trim leggy stems in spring. Remove any dead or damaged branches at any time of year.

Heavy pruning can be done after flowering to stimulate new growth.

Propagate Crotalaria aculeata from seeds, which germinate readily under warm conditions. Seeds can be sown directly into pots or the ground after the last frost.

Some species may also be propagated from cuttings taken in spring or early summer.

Repot Crotalaria aculeata every 2-3 years or when it becomes root-bound. Use a well-draining potting mix. Repotting is best done in spring before the active growing season begins to minimize transplant shock.

Choose a pot that is only slightly larger than the current one.
