How does clay affect plant growth?

Answer 1

Clay does help to hold in moisture, so in theory, this should give the roots of plants more water to soak up, leading to plant growth

However, clay can be difficult for roots to push through. Also, because clay does not drain well once saturated, it can cause roots to rot from excess water exposure and denial of oxygen to the roots.

Answer 2

Clay soil can hold water and nutrients well, but it can also have poor drainage which can lead to waterlogged conditions that suffocate roots. This can result in stunted plant growth as roots struggle to access oxygen and nutrients. Additionally, clay soil can become hard and compacted, making it difficult for roots to penetrate and grow. Amendments such as organic matter can help improve clay soil structure for better plant growth.

Answer 3

most plants dont grow as well in hard clay. although if you have house plants, some clay can be beneficial as it holds water for a long time.
