Soil for Ficus elastica
Ficus elastica needs a well-drained indoor potting medium and a pot that can empty excess water. The target is reliable drain-through, not a fixed bark, perlite or sand recipe.
Check how the mix holds water and air
Best soil mix
Use a well-drained indoor potting medium. RHS gives a loam-based direction for ornamental figs and Clemson supports a standard houseplant mix with reliable drainage for the rubber plant. No peat, bark, perlite or sand ratio is established.
Use drainage holes and do not retain saucer water. Excess water and poor drainage are associated with root rot and yellowing in the exact profiles, but free drainage is not a direction to let the root ball become permanently dry.
Separate indoor and outdoor advice
Match the mix to the pot and setting
This soil decision is for an indoor Ficus elastica container, where light, pot size, root condition and room temperature control drying speed more than a generic garden-bed label. Do not substitute outdoor ground soil for the container direction.
