    I have this Pleurothallis amparoana that's putting out a ton of immature, short growths. For a long time it just put out one or two normal growths at a time and now it has 15 new growths at once, all of them shrimpy.

    My question is, what's going on? ImageUploadedByTapatalk1442374037.614661.jpg

    Are you supplementing your fertilizer with some sort of growth stimulant?

    I have seen a large number of sympodial plants throw multiple growths with treatment of KelpMax, but they all mature normally.

    No. No supplement. I use 1/4 strength MSU weekly, and I use distilled water with a tiny tiny bit of MSU for daily watering.

    I've seen new divisions of pleurothallids do this, usually when they don't have good roots. They are like juvenile growths that remain small and the plant will usually revert to normal growths after awhile. If you can check the state of the roots under some of that moss you might learn something. I don't see a lot of healthy mature roots. It might be time to remount or pot it.

    I bet you're right Marni. It doesn't have too many mature roots. Any idea why not? I've had it over a year now.

    I had forgotten about it until Marni's comment but I had something similar happen with Pleurothallis dilema. I remounted it and used good quality sphagnum and it reverted back to producing normal leaves that matured properly. The original mount didn't seem bad but it looked like sheet moss or some poor quality product was used in the mounting. Also, in my case, the leaf tips on the mature leaves were browning and dyeing.

    FYI, in my situation, the stunted leaves are still on the plant and look healthy but look like they should be on a seedling.

    Ok then. Remount it is!
    Thanks all

    This also grows very well potted. You might check for bush snails (very, very tiny). As Kelly says, good quality moss. It makes a world of difference. I've started using coconut fiber instead of moss over the roots of mounted plants because even good moss goes bad too fast.

    Sorry to hijack this thread, but ....
    Marni, I used to use coconut fiber a lot more than sphagnum moss but it seems less available now. I see it on eBay in little ziploc bags but I used to find it in larger quantities and cheaper. Do you have a good source? I questioned John at Calwest and he agreed that it was difficult to find and they didn't carry it.

    Also curious about the answer to this and now watching this thread.

    When I talked to Jon a month or 2 ago he said he was looking for a source. I've recently gotten some from Botanica in Montana that was very good quality. No big gobs of coconut shell to pick out. It is on their website. It comes in 1 gallon ZipLock bags and seems to be of varying weights. Rather than feeling cheated by the 1/2 weight bags I looked at the quality and the price for the total quantity I bought and will order again. It isn't so inexpensive that I will be potting things in it, but for now that's OK. I have another source I am going to check into. If that pans out I'll try to remember to put it up here.

    Funny, ten minutes before you posted this, I found Botanica's coco fiber through an eBay search and bought a one-gallon bag. $4.95 plus about five bucks shipping. Not bad.

    I took it off the mount and it actually had quite a lot of healthy, growing roots. I think there must be some other reason for the dwarfed leaves.
    I replaced the moss regardless. We shall see what happens

    Lots of nice roots. I hope the remounting does the trick.

    At risk of hijacking this thread once again (apologies), Marni, can you give some tips on if and how you change the watering routine with coconut fiber as opposed to sphagnum? I just mounted two Masdevallia species with the fiber as an experiment. Thanks.

    Steven, The mounted ones with coconut are mixed in with all the other plants so are on the same watering cycle. The coconut seems to hold a bit less water than fresh moss and plants seem to be doing fine. As the moss ages, degrades and starts growing thick sheets of other moss on top of it there is too much moisture and not enough air. My reason for switching is the long term results. I will know better in 6 months or so.
