Soil for Gardenia jasminoides
Use peat-free ericaceous compost for Gardenia jasminoides. The root zone should stay damp while excess water can leave.
Check how the mix holds water and air
Best soil mix
Use peat-free ericaceous compost intended for acid-loving plants. RHS describes Gardenia jasminoides under glass in this type of medium rather than ordinary alkaline garden soil. No fixed home recipe is established.
Keep the root zone damp but well drained, never waterlogged. Choose a container and medium that can hold water without excluding air from the roots. The sources do not supply a universal irrigation volume.
Separate indoor and outdoor advice

Use an exact target only when one is known
Soil pH
Gardenia jasminoides is acid loving: RHS recommends ericaceous compost, while the exact profile records acid or neutral conditions. Maintain an appropriate acidic medium rather than adding lime by guesswork.
Check the pot, watering and roots too
