Weeping Mulberry

Could I use this as a privacy hedge? How many would I need for a 28' space?

Yes you could, but they only get to be about 5' wide each, so you would need at least 5 or 6 of them and they drop their leaves in the winter if you need privacy at that time of the year as well.

Do I understand correctly that I could limit the height to, say, 8 feet?

With annual pruning, yes.

I didn’t realize this was going to be such a small tree, the climbing roses from the same order are significantly bigger. - 1 gallon pot. What is the growth rate like?

Mulberry growth is largely water dependent. With enough water and sunlight they can grow up to 2' per year. If they are not watered enough they will grow much less quickly so plan for good supplemental irrigation.

Is "Weeping" similar to "Pendula"?

"Pendula" is a varietal term often used for "weeping" plants (from the Latin meaning drooping), but the botanical term is actually "decurrent". Hope that helps!

I would like a female tree. Will this be a female tree when ordering?

Yes this is a grafted female tree.

How wide does this tree get in diameter? I have limited space for trees to spread out.

6'-8' at maturity. It's much taller than it is wide (and it's not that tall).

What type of mulberry is your weeping mulberry most like? Pakistani?

It's more like a common Morus rubra, like Wellington or Illinois Everbearing.

To what country is this native?

The United States and Canada
