Clay, silty or sandy? Testing your soil type is an essential part of becoming a good gardener

Loamy soil is the holy grail, but all types can be improved by adding organic matter

I often mention my veg patch’s clay soil in this column, and that’s because soil type affects what we grow and how. Getting to know your soil is an essential part of becoming a great grower of edible plants. Soil type is determined by the size of the soil’s particles which, in turn, determine its characteristics.

Sandy soil has the largest particles, which means it is light, easy to work, lets water drain through it freely and warms up quickly in spring. This also means that sandy soil dries out easily, isn’t as water retentive as other types and tends to be low in nutrients as they wash through it.
