B. multiplex experiment

Post by johnfe »

I'm underway on a small scale experiment with a multiplex (Alphonse Karr, I think) that I got from a neighbor. I asked him if I could dig a little of his bamboo and he told me he had dug a bunch the day before - using a machete. I said I doubted it would still be good, but he showed me his clump, which had spent the night in a covered garbage can, and I thought it was worth a try, so we hauled it out and plopped it into my wheelbarrow.

It was huge! Filled my wheelbarrow, was about 9 or 10 in. thick, and must have had 25 culms, trimmed at ground level, with roots sticking out everywhere. The dirt was still damp enough that there might be viable roots in the mass, so I brought it home, dug a nice hole, packed it in wet compost, and kept it soaked for a few days. That was on about May 10 or so. The clump now has seven tiny shoots and some shoot-like things coming from the root areas of some of the brutalized culms.

Photo of shoot-like things:

I am keeping it well-watered and will document it's progress, keeping notes and occasional photos. I'll try to get a photo of the parent grove so some of you can help me decide if this in fact Alphonze Karr....[/i]

Just keep watering it and by mid-Summer you'll have a nice clump. It won't be full height, but you should have a nice bushy clump. And the shoots should like nice, clean, and pretty. My clump I used the fire/smoke treatment on to get it to produce seeds:

Yes you have a live clump starting up. From the pictures I do not think those are shoots 'Yet' (they will come) but new branches coming from the culm bases. Just went out side and looked at my A.karr shoots and even at 12' they are pointed with out any blade sticking out. Roy do you have a picture of an A. Karr shoot so he could see the difference? But it definitely is going to make it from the looks of it.

I wondered about that - I thought the ones in the first photo were shoots because I couldn't see where they were coming from, but now I see they look just like the ones coming from the base of the old culms... and they all do have the leaf blades on the tips, are looking more like branches now. Also thought it is too early in the summer for a multiplex to be shooting, but since I haven't done much transplanting of my silverstripe, I wasn't sure what the brutal digging might have done to it. But thanks for confirming my hopes that it's definite signs of life!

That's a nice clump, Roy! Hope this one looks like that in a year or so! Thanks for weighing in on my experiment, too.

MarCat,

From looking at the pictures, I believe you are right about the growth coming from where the rhizome meets the culm (I call them "survival node buds"). Once this new growth leafs out, then it can feed the other rhizomes under ground. Usually if the growth doesn't have any dirt around where it is coming off of the node, then it will be mostly like a branch. If it is covered with dirt, then it should produce roots and then produce rhizomes and new culms from this rooted piece. Sometimes it roots well enough I can take it as a division, but most of the times not.

I'll stop now! I'm getting dizzy. I think I'm beginning to go in circles.

Heck Roy your circle thought on Boo's are better than most strait line thoughts.
John my A. Karr started shooting about two weeks ago and most of my other multiplexes are starting up too. I am in 9a so yours should start soon. That clump there might have some shoot bud started and they may show up soon. If the clump has enough roots they should do all right but do not be surprised if some abort early. New shoots, I would guess, can be expected in a couple months and they should be smaller than the culms the clump had when it was dug. I believe you are going to end up with a few large culms and a bunch of small ones by the end of this shooting season.

All extremely interesting information! And there are now about 15 or 16 of these shoot/branches, so it's coming right along.

I'll try posting photos of the parent clump, tho it's in bad shape and mostly behind a fence, to see if you guys agree this is Alphonse Karr:

Just planted mine out for the second time 8) if things go to plan I'll be digging it up in two years :roll: for another two year stay in the greenhouse before planting out again...roll on GW....

Well, thanks for the encouragement, all!
Wondering how long that clump in Houston took to get so nice, Spiderman...

Thanks for the confirmation, Roy. Guess I could have made my photos a little bigger - kinda hard to see the detail. (Since I'm not posting them on the BW site, I suppose I don't have to follow that 200KB recommendation.) But my guess is you know the plant so well it doesn't take much for you to ID it.

It's really nice how the green stripes line up with the alternating branches... is that a typical characteristic of striped varieties, or just this one?

So Markj, is that process required in your climate zone for these tropicals to survive? For that matter, how the heck do you grow tropicals at that latitude? Gloucester? I know the Gulfstream does you favors, but you must still be about zone 6 or something up there... does this have something to do with the mystical GW you're referring to?

I believe it went in the ground in 2004.

John, Global warming- need stacks more to grow this to full size here :D , I think were 8b rather than 6. Not bad considering were at lat 52, sort of mid Canada for you guys :wink: we normally drop to around -6/-8 c in the average winter, and that'll be in dead calm, we never get sub zero winds that the 'boos really seem to hate.

These sub-tropicals don't seem to mind winter much, it's the darn summer thats kills them- the lack of any real summer heat and cool nights really sets them back. By the time they do wake up and start shooting the first of the frosts are just weeks away, we've a very short growing season, frosts up to mid may and then around mid Sept :evil:

I'd guess mine here will follow the same pattern, just planted out from an oak tub planter, probably 30inches round and 8 foot tall or so. It'll settle in and come late summer will send up some nice sized shoots, these will get frosted off without doubt. Come spring it'll send out some super small stuff to sort of make up for the loss and again the late summer ones will be frosted. The plant will just get smaller over the years, once it's shrunk back to a reasonable size I'll dig it up and start again. :?:

Only two of the semi-tropicals I've tried winter well and are looking good both sino-bambusa rubroligula and sishuensis are pretty good here. The plant labeled sino-bambusa intermedia is also hardy( here ) but isn't a sino-bambusa...

Markj you try planting them in black (heat absorbing) Pots?

That is just amazing! Had no idea that was what was happening... thanks for the explanation. This whole bamboo thing just keeps getting more interesting.
