Water Celosia elegantissima regularly, keeping the soil consistently moist but not waterlogged. Allow the top 2-3 cm of soil to dry out between waterings, especially during hot weather.

Reduce watering frequency in cooler months to prevent root rot.

Pinch back young plants to encourage bushier growth and more flowers. Remove spent flower stalks (deadheading) regularly to promote continuous blooming and prevent self-seeding.

Light pruning can also be done to maintain shape and remove any dead or damaged foliage.

Celosia elegantissima is typically propagated by seeds sown indoors 6-8 weeks before the last frost. Seeds require light and warmth to germinate.

Once seedlings are large enough to handle, they can be transplanted outdoors after all danger of frost has passed.

Repot young plants as needed when they become root-bound, usually in spring. Choose a pot that is only slightly larger than the current one. Ensure the new pot has adequate drainage holes to prevent waterlogging.
