Water thoroughly when the top 2-3 cm of soil feels dry to the touch. Reduce watering in winter to prevent waterlogged roots, which Calliandra selloi dislikes.

Ensure good drainage to avoid root rot, as this plant prefers slightly moist conditions.

Prune lightly after flowering to maintain shape and encourage bushier growth. Remove any dead, damaged, or crossing branches at any time.

Hard pruning can be done in late winter or early spring before new growth begins to stimulate vigorous flowering and shape.

Propagate from semi-hardwood cuttings taken in summer. Dip the cut end in rooting hormone and plant in a well-draining, moist medium.

Alternatively, seeds can be sown in spring after scarification or soaking to improve germination rates. Provide warmth and humidity for best results.

Repot every 2-3 years in spring, or when the plant becomes root-bound. Choose a pot that is one size larger than the current one, with adequate drainage holes.

Use a well-draining potting mix, such as a blend of peat, perlite, and sand, to ensure good aeration for the roots.
