Soil Foundations

Healthy gardens always start below the surface. Soil Foundations is where we explain how soil actually works — in plain language, without unnecessary jargon.

In this section, you’ll learn about the main soil types found in UK gardens, how soil structure affects roots, why soil pH matters, and how water, air, and organic matter interact underground. We also explore the living side of soil — worms, microbes, and fungi — and why they are essential for long-term plant health.

Whether your garden soil is heavy clay, free-draining sand, or something in between, understanding these basics helps you make better decisions and avoid common mistakes. Everything else on SoilCare builds on the knowledge shared here.
