We've done the research and can tell you which fruit and nut trees you can plant in clay soil.

These are some great fruit and nut tree options for clay soil:

  1. Apples (Malus domestica)
  2. Star fruit (Averrhoa carambola)
  3. Elderberry (Sambucus canadensis)
  4. Fig (Ficus carica)

What Is The Best Soil For Fruit And Nut Trees?

Typically, most fruit and nut trees will prefer a loamy soil type. However, there will be different requirements depending on the type of tree you're planting. 

It's also important to know the pH level that your tree requires. Many fruit trees require a pH level between 6.0 and 7.0. Nut trees tend to prefer soils with a pH between 5.8 and 7.0.

Test your soil to determine its pH level. This will help you determine how to amend your soil and can help you decide which plants to choose.

You can also test your soil's drainage with a hole and some water. Dig a hole at least 12 inches deep and up to 12 inches wide. Fill the hole with water, let the water drain, and then fill the hole again.

If the water drains in two to three hours, it means your soil has good drainage. If it takes less than two hours or longer than ten hours to drain, this is an indicator that your soil has drainage problems.
