Imagine a large, juicy, very sweet and seedless blackberry growing on a tree and you have Mulberry! Mulberries are small to medium sized trees, growing 12-15 feet tall with large, glossy, tropical-like foliage. Mulberries like 1/2 day to full sun, well-drained soil and are not bothered by pests or diseases. It is recommended that you plant your mulberry tree a little distance from any foot-traffic as the fruits will stain and are not great when tracked inside.
