Water Trichodesma calcaratum thoroughly when the top 2-3 cm of soil feels dry to the touch. Avoid overwatering, as this can lead to root rot. Ensure good drainage in the pot.

Reduce watering frequency during the dormant winter months.

Prune Trichodesma calcaratum after flowering to maintain shape and encourage bushier growth. Remove spent flower stalks and any dead or damaged branches.

Light pruning can be done in early spring before new growth begins.

Propagate Trichodesma calcaratum from seeds sown in spring, or from stem cuttings taken in late spring or early summer. Cuttings should be at least 10 cm long and placed in moist potting mix.

Seeds require warm conditions for germination.

Repot Trichodesma calcaratum every 2-3 years, or when it becomes root-bound. Spring is the ideal time for repotting. Use a well-draining potting mix.

Choose a pot that is only slightly larger than the current one to avoid waterlogged soil.
