If you’re looking to cultivate a thriving garden in heavy clay soil, you’re in luck. While clay soil can be challenging due to its density and poor drainage, many plants thrive in these conditions. By choosing the right plants, you can create a beautiful and sustainable garden.
What Makes Clay Soil Unique?
Clay soil is characterized by its fine particles, which make it dense and heavy. This soil type retains water well, but it can also become waterlogged, leading to poor drainage. Additionally, clay soil compacts easily, making it difficult for roots to penetrate. Despite these challenges, clay soil is rich in nutrients, which can support plant growth if managed properly.
