Ugh....I HATE those things. Nasty, nasty creatures....
Remember the "mulberry" tree I found in my back yard? Well....it has ZERO berries on it now so I am not sure it is a mulberry. I grew up around mulberries and pretty much remember them having berries all summer long. So I'm thinking it was/is some other kind of tree....
not all mulberrie trees bear fruits. I also heard it takes many years before they have fruits.
