Loam - Loam compromises the main body of John Innes compost. The loam aborbs nutrients in order to slowly release them to the plant as required. Organic matter is also contained within the loam; this provides slow release exchange sites for nutrition, promoting slow release of fertiliser to the plant.
Peat - Sphagnum Moss Peat contained within John Innes compost increases porosity, providing improved aeration and water-retaining capacity. Over time, peat decomposes slowly into humus.
Sand - Coarse sand helps to improve drainage by allowing excess water to infiltrate through the compost, preventing water-logging. Sand also helps to provide stability for larger plants.
Fertiliser - The compound fertiliser contained within John Innes compost provides macronutrients necessary for balanced plant growth:
