Best Plants for Heavy Clay Soil

Choosing the right plants for heavy clay soil can transform your garden into a thriving landscape. Heavy clay soil, known for its dense and compact nature, often poses challenges for gardeners due to poor drainage and aeration. However, with the right selection of plants, you can create a vibrant garden that thrives in these conditions.

What Are the Characteristics of Heavy Clay Soil?

Heavy clay soil is composed of fine particles that compact easily, leading to poor drainage and limited air circulation. This soil type retains moisture, which can be beneficial during dry periods but problematic during wet seasons. It often feels sticky when wet and hard when dry.

Key Features of Heavy Clay Soil

• High moisture retention
• Nutrient-rich due to slow leaching
• Compaction issues, reducing root growth
• Poor drainage leading to waterlogging
