Landscape value Mulberry is usually very tolerant of soil type, alkalinity and droughty conditions. Establishes easily and for the most part is a problem free tree. The growth habit is very dense so it needs to be pruned on a regular basis to avoid internal shading of branches. This internal shading will kill small branches giving the tree an untidy appearance. In the summer of 2002 when all of Colorado was experiencing a severe drought, well-established fruitless mulberry showed no ill effects.
