Mixing sand, compost, and other soil amendments can improve soil texture, air flow, and water drainage, making it easier for sunflower roots to spread and absorb nutrients.

Even with its drawbacks, clay soil provides several advantages, such as its ability to hold moisture and nutrients, which can benefit certain plants. Ultimately, clay soil is just one of the many factors to consider when planning a garden or landscape.
