Understanding Clay-Dominant Soil

What is Clay-Dominant Soil?

Clay-dominant soil, especially heavy clay soils, are characterised by their high clay content, leading to a heavy, dense texture. It retains water well but drains poorly, which can lead to issues with waterlogging. Compare this with sandy soils which are much lighter, easier to work with, and free draining.

Advantages and Disadvantages of Clay-Dominant Soil

While clay-dominant soil’s water retention ability can be beneficial during dry spells, it may cause problems in wetter periods due to poor drainage. On the upside, clay soils are often nutrient-rich, which can support the growth of many hedges.

Selecting Suitable Hedging Plants for Clay Soils

Factors to Consider

When choosing hedges for clay-dominant soil, consider their tolerance for waterlogged conditions and their nutrient needs. Some hedges thrive in the moisture-retentive conditions of clay soil, while others might struggle.
