Soursop - Single or split trunk?
« on: April 20, 2016, 08:02:11 AM »
I have a few saplings of soursop.  Out of these some have a single trunk like the one in the left and others have split trunks (right).  Should I be bothered?  Is one better than the other?  If yes, which one?  Thank you.

Interesting.  Single truck might give you taller, stronger tree?  Split trunk wider, shorter tree?  I don't know if there is a definitive answer to which one is better.

If you are willing to support the split trunk so it doesn't break over time with the burden of fruit, I personally would go for the split, because I feel like it brings the possibility of more fruit, and theoretically could make twice the number of branches. Plus, it might be more interesting looking. But if you are not pressed for space, I would of course think it is best to keep them all! :)

I don't know if tipping is recommended for soursop but i did anyways.
I got a small angle between the two branches and the both basically remained vertical. (same thing happened with my Malay apple)

I tried training one to go more horizontal and the truck just split, I applied very little force, I was pretty shocked how easy it was to split.
The tree is still alive though, I'm just going to let it do its own thing now.

I had the same experience.

Thanks for the replies, everyone.  BTW, I forgot to ask a crucial question in my OP.  This is my first time growing soursop, so which one is normal and which one abnormal?  From the above replies, it would seem the split stem is abnormal, right?  Out of the many soursop seedlings, I have quite a few split ones.

Also, what is tipping?

I personally do not like split trunks, I've had them split in the crotch and what is left is misshapen.
Regards,

Tipping is the practice of cutting off the terminal buds of all the branches.  One only cuts off the very tip to encourage branching.

Any reason why a lot of my seedlings split?  I haven't performed any tipping on any of the seedlings.

Thanks for the explanation, gunnar.

Watch this video by a professional soursop grower who has 1000 trees in production. if possible, get a Spanish speaker to translate. Note his techniques for pruning the trees very carefully to maintain scaffold branches and limit growth, maintain air flow, and fight insects. Also note the huge results he gets. There is a lot to learn here:

Way to add to the multitude of reasons I need to learn Spanish. Maybe knowing it can further my fruit addiction will help me to actually learn some this time. That's a heck of a video, absolutely lots to learn there.

UPDATE

John,

Your theory was right.  The single trunk ones have all grown taller, while this split trunk one is only about half the height of the former.

You can see both types of my plant in this thread:

Single trunk - fruited first


Split trunk - fruited second

Soursop is a very unique tree. They tend to grow vertically. If left to their own form that puts large fruit out of reach and hand pollination difficult. In my opinion fast fruiting is a secondary consideration, I'm looking farther into the future when I can harvest a dozen or more. I have six trees which were tipped at 2-3 ft. and I'm training them to be more horizontal using weights. It seems to be working, soon I'll make a video to show the results.

This fellow in Queensland explains how he is using trellising on soursop and some of his pro/con experiences.
