Pot-size watering

This plant usually prefers a snug root zone. Size up only when roots are circling, the plant dries out much faster than usual, or growth has clearly stalled.
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.
