Tropical Burnweed thrives in consistently moist soil. Water thoroughly when the top 2-3 cm of soil feels dry. Avoid waterlogging, as this can lead to root rot.

Reduce watering slightly during cooler periods if the plant is not actively growing, but never allow the soil to become bone dry.

Prune Tropical Burnweed to maintain shape and encourage bushier growth. Pinch back the tips of young stems to promote branching. Remove spent flowers regularly to prolong blooming and prevent self-seeding if unwanted.

Prune any dead or leggy stems at any time of year.

Tropical Burnweed is easily propagated from seed or stem cuttings. Sow seeds directly into well-draining soil in spring or summer, keeping them moist and warm.

Cuttings can be taken from healthy stems, treated with rooting hormone, and planted in moist potting mix.

Repot Tropical Burnweed annually or when it becomes root-bound, typically in spring. Choose a pot that is slightly larger than the current one, with good drainage holes.

Use a well-draining potting mix, such as a blend of potting soil and perlite or sand. Water well after repotting.
