Allow the soil to dry out completely between waterings. Trichodiadema barbatum is drought-tolerant and overwatering can lead to root rot.

Water thoroughly when the soil is dry, but ensure excellent drainage to prevent waterlogged conditions, especially during its dormant period.

Prune lightly to maintain shape and remove any dead or damaged stems. This can be done after flowering. Pinching back the tips can encourage bushier growth. Avoid heavy pruning as it can stress the plant.

Easily propagated from stem cuttings. Take cuttings in spring or summer and allow them to callus over for a few days before planting in well-draining soil. Roots typically form within a few weeks.

Seed propagation is also possible but slower.

Repot every 2-3 years, or when the plant becomes root-bound. Use a gritty, well-draining potting mix specifically for succulents or cacti. Repot in spring before active growth begins.

Handle the roots gently to avoid damage.
