Best soil mix

Use a peat-free loam-based houseplant compost. RHS ornamental-fig guidance adds fine bark chippings as an example, while NCSU describes a well-drained indoor medium. The sources do not set one bark, coir, perlite or soil percentage.

The container should drain freely while the medium remains capable of holding some moisture. Avoid a pot or mix that leaves Ficus lyrata waterlogged. Do not leave a saucer full or force the rootball completely dry.

Separate indoor and outdoor advice

Match the mix to the pot and setting

This is an indoor-container soil decision for Ficus lyrata, although the exact RHS profile also describes under-glass and frost-free outdoor cultivation. Container roots and indoor dry-down remain the primary frame.

Use an exact target only when one is known

Soil pH

RHS records Ficus lyrata as tolerating acid, alkaline or neutral growing conditions. That is a tolerance range, not proof that every pH performs identically or a reason to chase a narrow meter target.
