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

@fruitnut man those are consistently the best looking berries I’ve ever seen in a photo. You’re gonna make me add this cultivar for sure, I don’t have room to plant a mulberry unfortunately now, but in my head I have infinite room for potted plants haha

ramv, is that rooted in straight calcined clay?

50% 1/16 chicken grit, 50% vermiculite. Something I started trying this year.

Well it looks like it certainly drains well!

These two cuttings look like their holding color :face_holding_back_tears:

I have a few more popping up that is kind of yellowish so I’m assuming they haven’t rooted yet. Going to give it another month before i try to separate mine.

I’ve never seen a mulberry grow so quickly. This is only a week in the rooting chamber

They fruit right out of the gate. But will stop before long and just grow vegetatively. When the plant is big enough that you want to see a few fruit, just tip it back and bingo.

Makes me really want to try grow it in a pot and also try to hybridize it with one of the latest waking wild males here.

Some root

Some root incredibly quickly and some hardly at all. It’s the reason I learned how to graft because I wouldn’t be able to get some of the varieties without it :rofl:.

I’m not sure if there are any barriers for hybridization but I’d think your cold exposure would be the test for success. Seems like a cool project! You could basically grow it as a potted plant harvesting most to eat but saving some seeds to grow seedlings each year outside to see if anything shows cold hardiness. Probably a low-profile project if you are alright with maintaining a potted plant.

I grafted Morus Nigra to the Siam Jumbo. The graft took and grew about 12 inches. The next year, 2024, the MN was still dormant in mid summer after four months of harvesting SB. The point being that I think there will be graft compatibility issues with some of these things.

What I’m wondering is how many other mulberries can be forced into continuous bearing by pruning/tipping?

I know from personal experience that Valdosta can fruit a second time if heavily defoliated by, just purely for hypothetical example, an obnoxious family of three deer.

I might try tipping it this spring, Valdosta is much earlier than most of the mulberries around here, it’d be nice to extend its season.

Looks like I’ve found yet another mulberry to add to the list. Anyone know of a scion source to feed my addiction?

Was starting to bend in the chamber so i decided to take it out and look! No more than 10 days of rooting so far!

made a little grow dome to keep the gnats out. They’ve been immune to everything I’ve tried so far so i hope this works.

Almost forget, picked off all the fruit for now.

Wow, that’s a fast rooting process. Well done! I started rooting mine 2 days ago.

Yeah i was shocked! I’m scared to separate them lol

I won’t separate them until the pot is full of roots top to bottom. If you wait that long, there’s a near 100% chance both will survive. The earlier you do it the more setback and chance of killing them. That’s my experience with figs.

I did the figs by taking hand pruners and cut the rootball in two between the two cuttings.

Thanks! When did you get yours? I just looked at her site and unfortunately, it appears she’s out of stock.

Siam Jumbo may have rooted for me as well. Started rooting on 2-18. Compared to other mulberries, Siam Jumbo seems to root as easy as Bryce’s Worlds Best if not easier.
