Why cant plants grow in clay soil and what do they need from the soil?

Plants struggle to grow in clay soil primarily due to its compact nature, which limits aeration and drainage. The dense texture can also impede root development and restrict the availability of essential nutrients. For optimal growth, plants need well-drained soil that allows for proper air circulation and access to water, as well as a balanced supply of nutrients. Amending clay soil with organic matter can improve its structure and support healthier plant growth.
