Almost ripe pollen flowers on a male "fruitless" mulberry tree. This one tree will shed litterally billions of grains of very tiny, very allergenic pollen each spring. These male mulberry trees are commonly used as shade trees in elementary schools, and their pollen triggers many serious attacks of asthma.

It is quite easy to give these male mulberry trees a sex change, to change them from allergy causing males to pollen free females. This certainly beats having to chop down the tree itself. Read the comments underneath the photo of the female, fruiting Mulberry, for detailed directions on this kind of grafting. Also, take a look at the drawings of cleft grafts that are posted on this site.
