    My bulbo peltopus spikes keep blasting. The plant is growing well, so I know it's somewhat happy where it is. It throws out 3-7 spikes at a time, but they always blast once they get to about 1". They turn brown and dry up. I don't think it's insects as the whole spike browns at the same time (i.e. they aren't getting chomped in half at the base kind of thing). I suspect it might be that my winter water is pretty cold, but this is the only plant that seems to be having problems.

    Thoughts?

    Dammit man. I was afraid of that. I have a bitch of a time keeping it high in the winter. All the humidity condenses on the cold walls and runs off. Guess I'll adjust my mister intervals.

    Thanks Dale.

    I know how you feel, it's pretty tough keeping the humidity up there in the winter! We are having a similar issue with the same species, spikes get to about an inch or so then brown. What kind of temps do you have it in?

    Ok, we're close to those, we should probably cool it a little more at night. Thanks Jon.

    Our peltopus buds blasted because we were using a "round up" sprayer to water everything, and the metals from the tip and bladder of the sprayer started to enter the plants during watering. Hopefully you do not have this problem Jon. As you know peltopus is extremely sensitive to any and all water quality issues, including water temperature.

    Uh, have you actually tested water coming out of the nozzle for these "metals"?

    Maybe I wasn't clear Jon. The tip of our sprayer was metal. When we switched to a plastic tip sprayer, the problems with peltopus lessened. When we talked with other people growing the plant the first question they asked us was if we were using a sprayer with a metal tip that had the capability of oxidizing. The reason for our problems with this plant seemed to come from the use of a cheap watering device. I'm sure your operation is much more advanced than ours, which would eliminate you from experiencing this. All I wanted to do was explain the problem we had with our plant, isn't that the point of this forum? And no Chris, we never tested the water. We didn't have to.

    That's a strangely specific diagnosis.

    I'm a chemist and to make a claim like this, yes, you absolutely do have to test the water. Also, do you know what kind of metal the tip was? Do you even know what oxidizing means? An oxidizing tip is not putting metal into the water, quite the opposite in fact, most oxidized metals are incredibly insoluble.

    "we were using a "round up" sprayer to water everything"

    What, exactly, is a "round up" sprayer'? I know what Round Up is. It's a non-selective herbicide.

    I am aware of your credentials Chris. The reason we did not test the water is because when we stopped using that method of watering the preexisting problems ceased to occur. We were told by a an extremely credible source that the problems were due to our watering set up. I am passing on information about the culture of Bulbophyllum peltopus, and I do not wish chew tested about my knowledge of chemistry. If I offended either of you with my input, then I apologize.

    Dale, it's just a 4 gallon backpack sprayer made by the makers of "round up". It was an inexpensive way to water our plants before we switched to our current setup. Which is also an inexpensive way to water, just without a metal tip on the end of the sprayer.

    Also Chris, I guess I meant to say "has the ability to rust". The rust fragments began to exit the sprayer with the water, damaging our plants. That's all.

    I am aware that you went from taking an orchid class at a nursery to trying to grow and give advice on an extremely delicate species. I'm also aware that you actually believed it when this class told you that water spots cause burns. Your definition of "credible source" is highly suspect, as are your abilities to identify sources as such.

    Post hoc ergo propter hoc. You have no more evidence that changing the sprayer helped your plant than if I claimed I was actually praying for your plant to get better.

    Again, do you have any direct, observational evidence of this? What metal is the sprayer tip made of?

    I want Chris to pray for my Epigeneium lyonii to bloom. Couldn't hurt. Could you get started on that right away, Chris? Thanks.
