Senna occidentalis prefers consistently moist soil, especially during its active growth phase. Water deeply when the top 2-3 cm of soil feels dry. Avoid waterlogged conditions, which can lead to root rot.

Reduce watering slightly during cooler months or periods of dormancy.

Prune Senna occidentalis in early spring before new growth emerges to shape the plant and remove any dead or crossing branches. Pinching back young plants can encourage bushier growth.

Minimal pruning is usually required once established, focusing on maintaining a tidy appearance.

Senna occidentalis is typically propagated by seeds sown in spring. Scarify the seeds or soak them in warm water overnight to improve germination rates.

Transplants can be done once seedlings are large enough to handle and have several sets of true leaves.

Repot Senna occidentalis every 2-3 years or when it becomes root-bound. Use a well-draining potting mix and a pot that is slightly larger than the current one.

Repot in spring, preferably before the active growing season begins, to minimize transplant shock.
