The organic soil I use is regular soil for potted outdoor plants. A little rough in structure and not compact. Every country has different brands so I can’t put a name tag on it. Just be sure it isn’t for Rhododendron (unless it is for Azaleas or Rhododendron) but a neutral soil (PH soils can be classified with PH value: 6.5 to 7.5—neutral. over 7.5—alkaline. Less than 6.5—acidic, and soils with pH less than 5.5 are considered strongly acidic. 🙂
