Soil is nature’s best effort at a growing substrate and it acts as the support for the plants, as well as a source of food and water. Soil comes in a range of forms, from light and sandy to heavy and clay-like. Compost is the best example of a ‘Soil-type’ media, which has been formulated to emulate the different types of soils depending on the plants that are being grown. There are a variety of soil mixes available on the market that have been specifically developed and have special mixes to enable you to achieve excellent results. Many pre-mixed composts contain peat due to its high water and nutrient holding abilities. However, with the growing concern of peat bog depletion, some composts now contain less peat, but still have high water and nutrient holding capabilities due to the ingredients they have been replaced with.
