Default miltoniopsis and brown rot problems :(

I'm just about to cry from desperation! Trying to grow miltoniopsis is perhaps the hardest thing I've ever done. I just got my hands on a precious Miltoniopsis Andrea West only to have it die 2 weeks later... TWO WEEKS!!! D: and I used to think it was just me not providing the low temps it requires. It doesn't matter where it came from, what supplier, from the store or from the internet every single milt I've had succumbs to brown rot (psedumonas ssp.) they instantly begin to yellow at the center vein at the bottom of the plant then progresses to the whole bulb. They turn orange with a strange spicy-rotten small to them. kinda like fishy-apple pie-ish idk. in bark, in leca, in spagh, or mounted no matter what they do the exact same thing. It's so heartbreaking. If there's ANYONE who's had easy success with these please share your secrets because I just can't keep forking money over for dead meat :/ hopefully some of you hot climate peeps can chime in thanks

Here is some good information:

I am interested in trying one, someday. Right now, I have a Burrageara Nelly Isler 'Swiss Beauty'. It has the flower type but is very easy. Good luck!

watering. that's my opinion. miltonias and their cousins don't like to be wet. damp but not wet. and they do not like your water in aridzona. Use distilled or RO water only. Once I started using that my success rate went way up. And don't water it overhead. no water in the crown. feed lightly. to keep humidity up, place pot into a much wider pot filled with gravel or other media and water entire pot.

watering just approaching dryness, misting MAYBE if i think about it in the early mornings, no fertilizer, roomt emp water, and 30-40% rh. theres pleanty of air movement and again it doesnt matter what kind of media i have it in or repot in, theres always the same problem. i dont even know for sure if it is a rot but it sure feels like it. it has a distinct spice-like smell but with hint of rot and the plants have always turned orange. they never turn brown or any other color. they turn a bright orange and secrete a fluid from the affected areas that dont get mushy at all. the plants dont get mushy, they kind of just yellow and drop the leaves followed by orange smelly bulbs and the roots never seem to grow. also the newest growths seem to succumb first and whatever it is spreads through the rhizome.

Hello~
It does sound like erwinia kill. quick and stinky death!
Hot and humid is perfect for erwinia, and you are in southern Arizona! (I know it's dry but very very VERY hot, isn't it?)
You described your growing condition but I don't think I see what temperature range you tried your miltoniopsis.
Watering is not the issue here. I water mine with tap water like I do with everything else including myself lol and all grows and flowers well.

I killed my first miltoniopsis by overwatering/rotting roots.
Then I got a whole bunch of them again. I heard how they hate heat and blah blah...I was ready for mass death this summer.
Well, none died! In fact they are growing like weeds throwing lots of new leads. They just grow very slow, not sure if that's normal for these plants.

They are hybrids that have been removed far from the original species, so they are fairly strong I find. I'm sure they will grow much better through cool summer though.

Try them with air conditioned room if possible.
If you keep getting the same rot issue with them, try soaking them in preventive chemical solutions like physan and then grow them in inert media as in s/h.
but I think heat might be the center of the issue here. heat makes plants (especially miltoniopsis) weak, thus less resistant to diease. and erwinia loves heat!

By the way, orange seems to be the normal color when miltoniopsis dies.
All of mine also turn bright orange (or some of them just bright tan) when leaves die (due to aging).

I did get erwinia on my milts once but managed to combat it with Phyton 27.

I have found that they don't need to be that cool to do fine - I have had great success with 75 degree temps. The cooler you grow the more chance rot can set in, in my experience.

When I water I water from the bottom - I never mist them.

good luck - I know how frustrated you must feel - erwinia is the devil!

daytime temp 75 is ideal for these, which is why you had great success.
My apartment got so hot this summer reaching up to high 80s most of the times. I was worried but expected my miltoniopsis to die, but none did!
