How is substrate texture defined?

Substrate texture is defined by the size of soil particles, specifically the ratio of sand, silt, and clay present in the substrate. This classification is crucial because it directly influences various characteristics of the substrate, such as drainage, aeration, and nutrient availability, which are essential for plant growth. Each type of particle affects how water and air move through the soil, which impacts overall plant health and the effectiveness of the growing medium.

Understanding substrate texture allows growers to make informed decisions about what type of plants to grow and how to manage watering and fertilization effectively. For instance, a sandy substrate drains quickly but may require more frequent watering, while clay retains moisture but may cause drainage issues if water cannot move through it efficiently. Thus, knowing the texture aids in predicting how a substrate will behave in different moisture conditions and impacts plant care strategies.
