I've been having a ton of trouble finding info and, given the nature of this situation, I suspect this is where I'm most-likely to find the answers I seek- I've been growing-out a papaya tree for a couple years (accent plant behind a bonsai-bench, have exposed its roots and everything, real cool specimen!) and, this past winter, a frost killed the growing-tip - but papayas don't do branches, they're just single-trunked trees, I thought it was dead when I found the top had died.
Shortly thereafter this thing started throwing buds all over, mostly concentrated in the middle but there must've been 25+ buds on that thing, and I was only able to find 1 pertinent piece of info online, a FL extension website (gov't/university url), that advised that, in such situations, you choose a new shoot as leader and support it until the tree's taken to it.
I love niwaki ('japanese style in-ground topiary' is a good description I think...wiki has a great page on it ) and, seeing an opportunity for a special papaya (ie, not a single-trunked papaya!), I rubbed-off every bud except for 3 (at ~60% of the tree's height) and they're growing-out well.
The problem is that, since it kept pushing more buds (and started to focus them towards the top of the trunk), and I just want to develop the 3 new shoots into 3 growing-tips/leaders, I did something I was going to wait longer to do- cut-off the trunk above the new 3 shoots I want. I figured it'd be fine but, after cutting, found something unexpected- this tree is hollow!!! There's a cavity that runs the whole length, so my idea of sealing the cut with Plumber's Putty suddenly didn't feel right....I don't want to leave the hollow wide-open, I expect that'd just invite bugs to live in there, water to accumulate, etc and kill the tree from the inside-out. At the same time, I'm unsure whether, on a perfect specimen, if there wasn't always a little opening at the top (maybe it's an air-exchange thing?)
So I'm unsure what on earth to do right now, I've sealed it up w/ painter's-tape as a temporary seal, part of me is thinking of just putting a golf-ball in the hole and then sealing the top w/ putty but I just don't know if that's needed to breathe....I didn't leave as much excess-height above the highest new 'leader' branch as I should've, so any excessive die-back will probably kill that shoot (I guess a 2-trunk papaya is still special but really want the 3 to survive!! I couldn't find a single image on Google of multi-trunked Papayas! And it's basically an 'accent plant' for my bonsai-display at this point, it sits directly behind a bench[probably why it grows so fast!] and, w/ 3 trunks + exposed roots, will be awesome- so really don't want to lose this guy!!)
Thanks for any help, I know it's not bonsai but pasting cuts / these scenarios aren't something I can think of anywhere else to ask (the generic gardening sites I know were unable to help, would love a reco for a good general gardening forum if anyone knows one )
Pics of the cavity, and pic of the tree itself (last pic- the tree's in the upper-left quadrant of the shot coming out of my mexican-sunflower patch, there's just so much green it all blends together lol, sorry for not having put a background to it but think it gives an idea of size and location of the cut-top // new-shoots)
Thanks a ton for any help on how to handle this, I love this tree and am psyched at the prospect of having a squatter, multi-trunked papaya - a rare sight - but w/ that hollow-trunk I've no idea how to treat/care for it :/
