Water thoroughly when the top 2-3 cm of soil is dry. Cassia abbreviata prefers well-drained soil and is relatively drought-tolerant once established. Avoid overwatering, which can lead to root rot.

Reduce watering during cooler, dormant periods.

Prune lightly after flowering to shape the plant and remove any dead or crossing branches. Heavy pruning is generally not required.

This encourages a bushier habit and can improve air circulation, reducing the risk of fungal diseases. Remove spent flower stalks.

Propagation is typically done from seed, which requires scarification or soaking before sowing. Seedlings can be slow to establish.

Cuttings can also be taken from semi-hardwood in summer, though rooting success can be variable. Patience is key for successful propagation.

Repot young plants every 2-3 years or when root-bound. Use a well-draining potting mix. Established plants in the ground rarely need repotting.

Choose a pot that is only slightly larger than the current root ball to avoid waterlogging. Repot in spring.
