Pot & Soil
Prefers a compact, shallow pot. Standard well-draining potting mix.
Pot-size watering
The 8-12 day range is a starting point. A 5cm pot usually dries faster than a 22cm pot; use the dry-down check as the final signal, not the calendar alone.
Shallow roots
This plant is better matched to a shallow or wide pot than a deep one. Deep wet soil below the root zone can stay damp too long.
Soil refresh
Top up or loosen the surface yearly, and plan a fuller soil refresh when the mix compacts, smells sour, drains poorly, or the plant needs repotting.
Good to Know
Leaves open and close with light. Goes dormant periodically.
