- It can be difficult to identify trees with variable leaves like white mulberry (Morus alba)! Learn all the tips and tricks here, and especially learn the differences between white mulberry and closely related but relatively rare native species red mulberry, Morus rubra. We also discuss why the spread of white mulberry as an invasive is a threat to red mulberry in particular.

I love these random nerdy videos. Thanks! Very informative and now I can’t wait to get home and see if ours are white or red! It just now is starting to flowe/fruit after 5 years!
I live in Texas and I have found several white mulberry trees growing in old forest in very shaded location. Also I have found red mulberry trees growing on the edges of forest in full sun. Seems to me that the best way I've found to identify them is by to their leaves as you have described. Also you never find a white mulberry leaf shaped like an oven mitt but it is very common in red mulberry.
From Missouri and was curious about where you found you're identification fact knowledge for sound information please?
I have a fruiting white mulberry tree in my yard based on the leaf identification, it's growing in a cluster of trees and is almost in full shade under a huge maple tree. This is SC so it's always 1000 degrees in the shade too so that might be why it's doing so well.
Very informative, Thank you!
White mulberry fruit and red mulberry fruit is also good maybe better is good but hybrid mulberries like illinious everbearing mulberry, silk hope mulberry they can be invasive but they aren’t as invansive as true white mulberries the fruit quality is superior then white and red mulberries and they grow longer fruits usually and there is even less invansive form called Gerardi dwarf that grows big long edible sweet fruit. There is also morus nigra a seperate species that is good in warm climates and is called the king of mulberries because it has the best fruit is best but the plants harder to grow. Also morus latifolia fruit is good to of kokuso Korean mulberry. Some white mulberries grow good fruit like Russian mulberry if you keep it pruned you should be fine. Also you can Graft white mulberry roots to superior hybrid or nigra type mulberries.
Oh crud, I have this in my backyard.
Would you mind showing some trees?
That was really helpful!

Also I have found a way to identify the trees in winter while they are dormant. I take a cutting and root it in a warm place and when it puts on leaves it will also fruit so I'm able to identify and sex the tree at the same time.
I was really happy to get fruit from my mulberry tree in my backyard (Northwest Indiana) and am now sad I need to chop it down. I think it's white mulberry due to the leaves being so shiny (3 lobe). It does look very weedy. It's still hard for me to tell the difference though.
I know what you mean, I enjoy the fruit too, but removal does help protect our native red mulberry populations. If the tree is in your yard, especially in a sunny spot, and the leaves are shiny it's very likely to be white mulberry. Red mulberry leaves are dull on the top surface and hairy on the entire bottom. Red mulberry requires higher quality habitat with rich, moist soil and partial shade, while white mulberry will grow in poor soils and prefers full sun.
I'm in northwest Indiana too, you still have your tree?
Hello, you mentioned male and female white mulberry. How do you tell the difference between the two ?
The easiest differentiation is whether the tree produces fruit. Only female trees produce fruit.
The weedy nature can’t be overstated. I had no idea the male pollen travelled that far either. There’s a very large “mother” white mulberry tree at the bottom of my street, easily over 2 feet in diameter. A few hundred feet away in all directions I can find more and more of them springing up in people’s yards.
Do you know if the 'silk hope' mulberry is invasive? I believe it is a cross between the white and red (alba and rubra.)
Yes, this is a hybrid of white and red mulberry. If it was purchased, it is most likely a male cultivar, as those are still in trade in many states. Whether this tree is regulated as invasive, varies by state. In Indiana, Morus alba, and all cultivars are prohibited for sale. If you have this tree on your property, our guidance would be to remove it. While Male cultivars of white mulberry do not produce fruit, they can pollinate wild growing female plants, contributing to invasive populations. They can also contribute to declines in native red mulberry populations through hybridization when planted close to forests.
@@midwestinvasiveplantnetwor7029 i have a male mulberry that is 20 yrs old. And yes its roots have spread more than I wanted. I just bought a potted silk hope mulberry that is supposed to grow fruit. Will it be affected by the male old tree?
@@sheri023 The old tree, being male, could pollinate the new, fruit-bearing tree causing any offspring to be hybrids, which would have varying characteristics. The cross-pollination may improve the fruit production of the new tree, but that may have the unintended consequence of increasing the spread of white mulberry as birds eat the fruit and deposit/disperse the seeds.
@@midwestinvasiveplantnetwor7029 thank you very much for your answers. 🌳
@@sheri023’silk hope’ is a female fruit producing cultivar not male. They are not invasive unless a male tree is pollinating the fruit.
The Story sound like some human story in North America
4:06 So, it produces black fruit, but it's called a white mulberry. Go figure.
Some white mulberry trees actually have white fruit
can you graft it with a black mulberry ?
As white mulberry is invasive and black mulberry is not native to North America I would not advise this. Native species that have co-evolved with pollinators, help maintain biodiversity, support environmental resiliency, and provide far greater ecosystem benefits overall.
It doesn’t matter if you want fruit you can do whatever you want. The roots should be fine black mulberries are harder to grow morus nigra and grow superior berries to native red mulberry there need a special climate to grow so make the best out of the white mulberry you have.
@@midwestinvasiveplantnetwor7029it won’t matter if you morus nigra is harder to grow.
what i got here its pretty worthless
i wood love to get fruit that's worth eating @@Youdontknowmeson1324
I have a question
In my area there are some female mulberry trees that produce a lot of fruit and that fruit has perfectly formed and fertile seeds inside, in fact I have seen those seeds grow
but there is not a single male tree for miles away, and I don't understand how they get pollinated.
How is it possible for them to produce complete and fertile seeds?
thank you
While mulberries tend to be more productive if they are cross-pollinated, they are self-fertile and so do not require a male tree to produce fruit.
That is interesting!
