I bought two weeping mulberries this year, and I am really excited about them (see pic).
However, something confuses me. The person I bought them from says that each weeping mulberry (at least those that she sells) requires two grafts: one at the bottom, and one at the top.
Is that true?
And, if yes, why is that?
(I can't visually confirm that, all grafts are done so that they are almost not noticeable. I know though that unwanted shoots from the middle of the trunk have different leaves than those in the weeping crown.)
