mulberry
桑 centers on the mulberry tree, a plant cultivated for its leaves which feed silkworms.
桑 is a pictograph of a mulberry tree, with the top 叒 representing the branches and leaves and the bottom 木 the trunk and roots.
The top 叒 looks like layered branches with leaves, and the bottom 木 is a tree. Together they form the mulberry tree.
For ソウ, imagine sewing (ソウ) silk from silkworms that feed on mulberry leaves: sew -> ソウ, and the tree provides the silk.
