New root from an external root?
Hi,
Today I noticed a new growth on one of the external roots of my phalaenopsis. It's small and pointy, so I'm assuming that it's a new root. Is it normal to grow a new root from an old external root? Or could it be something else?

Hi Mike:
I have the same thing taking place on my phaelenopsis but it turns out to be e flower spike. Mine is not growing from a root but from the base of the pha. where the other roots growing are. |

I'm glad you added that 2nd sentence. If you thought you had a flower spike growing from a root I was going to have to see a picture of that! ;-) That brings us back to your first line. How can you say that you have the same thing when the original post was about something growing from a root? Congratulations on the new flower spike though. :-) Steve |

Thanks for the replies.
I think it is a new root. The existing root has a part that's exposed (and therefore, woody) and the rest of it goes into the growing medium (and probably green and fleshy). The new root is emerging from the part of the old root that is exposed. I have a question about roots that are green and fleshy... As you guys know, there is a thin wiry structure in the middle of the root. If when repotting the orchid you notice that some segments of the green roots are broken but still attached to the inner core (wire structure), will those segments still survive? Or do the roots have to be one continuous root with no breaks? I always remove any dead/mushy parts, but I'm just wondering if I can leave the rest that appear to be hanging by the "wire"?

Mike That's actually a really good question. I think the part below the break does live on at least for a while. I suspect the broken part probably tends to die quicker than it would otherwise but who knows what really goes on down in the pot after the repotting is completed. I don't! If I'm repotting a plant and it has more roots than it really needs, I remove the broken roots. If the plant is a little low on roots, I'll save the broken ones on the theory that the plant should get some use out of them while they last. Steve |
I've asked that question before I think, and the answer I got was that
it sort of depends... If it's just s simple break in the root, then there isn't really a problem, but if an entire section of root is missing (i.e. root-core filament-root), then you're better to cut off the distal portion which will eventually die and rot in the pot.

I'm never quite sure how to treat dying roots either.
My observation with Phals having dying roots: The velamen (the fleshy root coating) is what absorbs the nutrients, and Phal roots grow from their tips. Dead tip = dead root, eventually, unless the main root has other branching tips that can sustain the main root. Also, if a root is rotten up toward the base of the plant, the entire root will probably eventually succumb (as autopsies have revealed). Sometimes, air roots will branche off and go down into media and sustain a plant, but sometimes they won't. Somewhere I read on this NG that one shouldn't cut off the core filament even if the velamen is gone. Well, I've cut off filament and I've left it attached, and I can't say that it made much of a difference either way to a Phal's ultimate survival. I haven't seen new roots growing from a naked filament. If you have some short, stumpy live roots (that you expect to develop into larger media roots) or if you have air roots, the filaments are, however, good for anchoring the plant into the media so you don't have to resort to pot clips to keep the plant from falling out of the media.
