Why isn't my Mulberry tree fruiting?

Posted by monsoon99 Z9 CA (My Page) on

I bought a Black Beauty Persian Mulberry tree 3 years ago. It was a good size when purchased (3 feet tall) Every year it puts out lots of leaves starting in June or so and then nothing. I dread that it is a male tree. Anyway I can find out if it is male or female or does it fruit after many years. I would hate to pull it out after so many years of loving care.

maybe its too young? Not enough light, phosphorous, or other nutirents?? You said it is 3ft, thats a bit young afor a tree to be fruiting.

Has it flowered yet? If not, patience.

Second, any fruit tree tag will tell you whether this var is self-fertile or needs a pollinator (hard to tell sometimes with all the grafting going on).

The briefest Googles shows that this var is self-fertile, plus, it is common in cities to have pollinators close by anyway.

So as it is self-fertile, you have to wait until the plant reaches sexual maturity. I would also scrutinize whether your loving care translates to a fertilization regime that makes the plant sad & refuses to flower. Just a thought.

==>> and that was my first thought ... loving it thru a fert balanced in the wrong direction for fruit .. rather than a lot of greenery ...

but if you dont fert.. then its simply age ...

3 foot is NOT a rather 'good size' tree ... mine is about 40 feet tall ...

frankly.. patience is your only remedy.. is far as i am concerned..

a fruit will fruit.. when it wants to fruit.. and not a second sooner ...

fruiting is a function of sexual maturity .... and just like the average teenager.. it happens.. when it happens .. and there is nothing you can do.. to speed it up.. or slow it down ...

so, for example.. i dont see how you could fert a 12 year old to maturity faster.. by feeding him.. and would analogize to a tree ...

i dont care where you post.. but there is a fruit forum.. and they do things much differently than tree peeps do.. so you MIGHT get a different answer there.. or find someone who actually grows mulberry for fruit ... mine came with the house.. and were bird planted.. just like the hundreds i kill every year .... as i said. IMHO.. they dont need much of anything to grow... lol .. much to my dismay ....


RE: Why isn't my Mulberry tree fruiting?

My fertilizing regimen is not vigorous so I am not worried about too much of that. The tag says it is self pollinating Persian Black Beauty mulberry tree. It is also a dwarf - tag says will grow up to 15 feet tall. I did some further research after my post and it appear I have to wait for a few years before it fruits. I also read that male mulberrys do not fruit and was worried that mine was a male. I hope the tag is right. I just wish I could know with more certainty how much longer I have to wait before it fruits.

RE: Why isn't my Mulberry tree fruiting?

There should be no worries about it being a male tree if you bought it.

What you bought isn't a tree that was grown from seed, what you bought is a limb from an existing tree that was grafted onto rootstock. Just look down around the base and you should see the scar.

Now, before you start thinking you got ripped off or something, this is common practice, perfectly acceptable, and it will grow into a normal tree in time. It also means that it was taken off of a female tree that produced suitable fruit, and so will it.

It should start bearing fruit in 2-3 years after you bought it. In the mean time it has to establish sufficient roots (that usually takes at least a year) and then bulk up the upper portion (another year or two) before it can support fruit.

Basically when it stops looking like a stick and looks like a tree, it should start bearing fruit.

Needs treatment with a product known as 'Time'. Apply about 5-10 years of the product at a steady rate.


RE: Why isn't my Mulberry tree fruiting?

Thank you Edyminion. Based on the information you gave, I feel much more confident that my tree will fruit at some point. As you see from these posts the estimates range wildly between 2-3 years and 5-10 years. I hope sooner than later....

Thanks everyone.

RE: Why isn't my Mulberry tree fruiting?

Yeah, the time differences are mostly due to the differences in how the tree starts.

From a seedling, its 5-10 years before they bear fruit, as it takes that long to go from seed to suitably large tree. When you get a grafted branch from the store, its already the size of a tree thats been growing for several years, so it had a head start.

I have a fruiting mulberry in my front yard I planted several years ago, and it had fruit last year. Off the top of my head I'd say its in the 10-15 foot range right now, and was maybe 3-4 feet when I bought it. They grow fairly fast.
