Allow the top 2–3 cm of soil to dry out between waterings. Water deeply but infrequently — approximately every 7 days during the growing season, less in cooler months. Avoid waterlogged conditions as this plant is highly susceptible to root rot.

Use a light, well-draining potting mix with added perlite or coarse sand. Avoid heavy clay soils. A slightly acidic to neutral pH (5.5–7.5) is ideal. In coastal gardens, sandy loam soil works perfectly.
