As with garden soil, potting soil can attract insects. For example, the fungus gnat is often found around houseplants because it lays eggs in moist potting soil. [22] Infections of Legionnaires' disease due to potting mix have been reported in Australia, [23] New Zealand, [24] the Netherlands, [25] the United States, [26] and Japan. [27]

Each plant species achieves maximum growth in a particular pH range, yet the vast majority of edible plants can grow in soil pH between 5.0 and 7.5. Soil scientists use a soil classification system to describe soil qualities. The International Union of Soil Sciences endorses the World Reference Base as the international standard. [2]
Grafting is referred to as the artificial method of propagation in which parts of plants are joined together in order to make them bind together and continue growing as one plant. Grafting is mainly applied to two parts of the plant: the dicot and the gymnosperms due to the presence of vascular cambium between the plant tissues: xylem and phloem.

Gradually soil is able to support higher forms of plants and animals, starting with pioneer species and proceeding along ecological succession to more complex plant and animal communities. [6] Topsoils deepen with the accumulation of humus originating from dead remains of higher plants and soil microbes. [ 7 ]
