    Unhappy Dendrobium aborting new growth

    I have a Dendrobium hybrid (Sena Red) that has been aborting all of its new growths despite appearing otherwise healthy. Anyone have an idea what it might be lacking?

    The story: I bought it in bloom with two canes from a BBS in 2008. After that blooming it grew a third cane which bloomed last summer for quite a long time. Towards the end of that blooming it produced two new growths that both aborted while very tiny. I cut off the spike then thinking it had been in bloom long enough at that point. Then, over the winter that same cane produced a second spike, which given the low light levels wasn't much to look at, but I let it do it's thing and didn't cut the spike until all the flowers had dropped and the spike had gone brown. That was relatively recently. It recently had started a new tiny growth off of a different cane in the last couple weeks but now looks like that is not progressing either.

    It is in a south-west window, currently getting full sun. No fears of sunburn yet, though in summer I will pull it back a bit. Winter is very low light here but time changes quickly so light levels are increasingly quickly. It hasn't lost any leaves or shown other signs of distress. I repotted it when I originally got it and as far as I know the roots should be in OK shape.

    I have a very similar hybrid dend (Polar Fire) right next to it and that one currently has two new growths making good headway so I don't really see what the problem is!

    That sounds suspiciously like something (like aphids, mealybug etc...) is getting to the new growth and stopping it from forming correctly. Inspect the new growth closely with a magnifying glass.

    And you might want to consider repotting. Your medium may be breaking down. Alot of den's I get have a huge plug of fiberous stuff in the middle. When they were small plants someone put them into this plug and before you get it it's repotted again; only they do not remove any of the original material. So that material decays the inner roots and new growths; and leaves you thinking you killed it.

    Thank for the tips. I did the initial repotting when I purchased it in 2008 and it hasn't lost any leaves or flowers, but I suppose repotting may be the order of the day.

    Update: One of the older canes now looks like it is going to produce yet another spike. Sheesh.

    Haven't repotted yet though...

    Update: I think I finally figured it out! I finally got a new growth to grow big enough that I could see actual bites taken out of it. And not too long later I caught a glimpse of the culprit - a tiny snail!

    No idea where THAT came from, but snail removed and growth is now progressing well. Plus I have a spike with 11 buds on it - hurray!

    Great news!

    Those snails are really sly critters. I had one that removed sections of my Ivanagara Apple Blossom blooms steadily and systematically- each night a 3rd of a flower would disappear, and I couldn't find what was doing it. Over the weekend I took the basket apart and found the varmint sleeping peacefully, waiting for nightfall so that it could gobble up my remaining flowers. Of course, I made short work of him(/her).

    I have seen similar snails amongst my orchid roots. Very tiny, laterally compressed and dark tan to dark brown.
    They prefer to hide among the potting mix and nip on fresh root tips and new growths that are still tender.

    Good news is that they dont seem to have high populations like slugs and garden snails. Bad news is that they are so hard to spot unless you start to see damage on the plants.

    For my greenhouse, I use a snail/slug killer powder and sprinkle on top of the potting mix regularly, paying special attention to plants that are developing new roots and new leads.
