Trees for clay
This excerpt has been taken from “Tree for the Yard and Garden” by “John Cushnie”. Trees for clay, majority of the roots will develop in the top 12 to 18 inches of soil, though this will vary depending on the type of tree and garden soil. “Tree Removal Berkeley CA” gives you info on such trees.
Some clay soils that are wet in winter become dry, hard, and cracked in summer. Other sites only appear to be wet because the soil surface has been compacted, preventing the water from soaking down through the soil. Breaking the surface crust may solve this problem. Only a proper drainage system will offer a cure for soils that are truly wet or waterlogged all year, although an alternative is to raise the soil above the water table in a mound, allowing the tree to spread its roots above the waterlogged area. Where this isn’t an option you will have to plant trees listed below, which are tolerant of cold, wet, winter soil conditions.
