What do British gardeners mean by grit?

In the world of gardening, the term “grit” is commonly used by British gardeners to refer to a specific type of material that is similar to what we in other countries might call decomposed granite or crushed granite. It is typically used as a component in soil mixes, especially for plants that prefer well-draining conditions.

Grit is highly valued by British gardeners for its ability to improve soil drainage and prevent waterlogging, which can be particularly important in areas with heavy clay soils that tend to retain water. It helps to create a more open and porous soil structure, allowing excess water to drain away more easily and preventing roots from becoming waterlogged.

Obtaining grit can be relatively easy or quite challenging depending on where you live and the availability of local sources. In areas with nearby granite quarries, it may be relatively easy to find and obtain crushed or decomposed granite, which can be used as a substitute for grit. However, in areas without such local sources, it may be more difficult to find and may require some searching or purchasing from specialized garden suppliers.

Crushed limestone is another material that is sometimes used as a substitute for grit in the UK. However, it is important to note that limestone can have an effect on soil pH, potentially raising it and making it more alkaline. This can be problematic for certain plants that prefer acidic conditions, so it is important to consider the pH requirements of the plants you are growing before using limestone as a substitute for grit.

In my own experience as a gardener, I have found grit to be a valuable addition to soil mixes, particularly for plants that require well-draining conditions. I have used crushed granite as a substitute for grit in areas where it is not readily available, and have found it to be effective in improving soil drainage and preventing waterlogging.
