Update: Siam Jumbo mulberry: cutting to huge fruit in 5 months

For those asking my plants are all gone. I’ll maybe having cuttings this summer. But I’m not sure when I can cut it back. It’s already too vigorous.

Have you tried growing any of them outside in your area just for fun?

Normal blueberries get frozen out here in the spring most years. Our temperatures are way to variable. But I might as well give it a try. I’ll try own roots and try grafting it onto my Silk Hope.

Hi Stan
Glad to hear your graft is working! My rooting effort got a slow start. I initially placed them in my greenhouse but after several weeks of observation I decided that the night temps were too cold, so I moved them indoors in a south facing window where they now seem to be perking up. These three are the best looking of all 9 attempts. I have been sniping off the fruits to conserve scion energy for foliage growth. I hope that’s these can pull thru!

Maybe I’m seeing things but it looks like a male flower on one of my trees(I have two grafted)


I was actually hoping to get some male flowers at some point(ideally a whole branch that stays male after regrafting) for a good breeding male.

I haven’t seen any males on mine. But then I’m no mulberry expert and haven’t ever seen one that I know of.

I chopped out a banana and planted Siam Jumbo. My in ground tree is too vigorous. I won’t be able to tolerate it another year where it is now.

The mix in this pot has a long history. First it grew a fig plant. Then flowers for my greenhouse pollinators, then the banana. I think it’s still a perfectly good media for a mulberry. I expect the Siam Jumbo to get pretty big as the pot is about 25 gallon.

Hoping to get some ripe ones soon if the birds will leave them along. Seems like as soon as they get red they’re pecking.

The birds like them.!! That’s a good sign. I think you need some bird netting or this may be hopeless.

Have you tipped anything yet to see if it will set more fruit?

I tipped one of them yesterday. Im letting them grow as much as possible right now to let it beef up. I may try tipping and pruning later to encourage more fruit.

What do you feel is the best strategy for pruning for continuous fruiting?

Since mine is outside I also want as much wood to be lignified as possible for winter, but sometimes we don’t get frost till November.

Just keep tipping as soon as any shoot quits setting fruit. I’m on the third tipping and now it’s just running all together. Whenever I see a shoot that’s stopped fruiting, I tip it.

Do you tip while it is still ripening other fruit or wait until everythings ripened then tip?

I tip even before I’m sure it’s stopped setting fruit. It only sets about 6 nodes so if it’s grown 6 nodes, tip it. It takes a while, a week or two, to see the newly set fruit. It doesn’t seem to matter. Anytime it’s tipped it sets fruit.
