- MILTONIOPSIS ORCHID CARE - Where did I go wrong? In today's video we look at the worst looking orchid I currently have, which started to show signs of stress during summer in 2019.
We discuss what I've since learned about it both from my research and from my own experience and compare and contrast the two.
I then hope to rescue my Miltoniopsis by providing it with the cultural conditions it needed in the first place.

Miltoniopsis exist in cloud forests in the wild - mainly between 1000 and 2000 metres. The temperatures in these forests rarely goes above 20C and they have an average temp of around 17/18C. Humidity is always high and the light level shady. Anything that grows in a cloud forest will be a cooler grower. In cultivation, the main problem is root loss leading to high stress levels where heat just adds to that stress as does too much light, stale media and not enough humidity. What it will 'put up with' will be totally dependent on how good the root system is. Some of the info given is 'doggy' to say the least - the sure sign is anywhere where it says 'weakly weekly' - what if it's still wet? On yours, the pot was far too big which leads to not drying fast enough which leads to the roots being too wet for too long. A pot that stays wet creates a stale environment. The idea is for quite a quick drying which allows fresh water to be added more frequently. In a cloud forest, the plants are dripping wet almost all of the time - but this water is constantly being refreshed. The moss will help a lot - just need some roots to start and the pieces should eventually recover. Try low light levels until some roots get going.
Thanks for that detailed comment Roger, it'll be very useful. I've made a couple of changes based on your take on things. I've linked to the article I gleaned the info from in the description. Ned Nash has some credibility in that he's written for the American Orchid Society (this article is on their website) and is the author and co-author of several books on orchids, so as to whether his take on Miltoniopsis is 'dodgy' I'll leave that to others to decide. My limited experience so far has clearly led to rotten roots, and there's no way I can keep my freestanding greenhouse up to the temperatures he's recommending anyway. The minimum night-time temps will be 16°C but during the summer the daytime will be much higher than 20°C. It's the winter when I'll struggle. As you can see from the video, I've repotted it into a much smaller pot. The humidity will be high (until I have to ventilate! ) and I can sort the shade out, so hopefully, the greater temps, combined with the smaller pot, and the moss around where roots should emerge will help. If they don't, then I've just wasted my money on buying yet another one! (Some might say 'glutton for punishment' - but I prefer 'doggedly determined'!) 😂
@@Grow_Up_Man55 I have a dozen or so books on orchids for decorative purposes as the info inside is often mis-leading (polite version). One of the best orchid growers at BOS who is also the holder of the National Dendrobium Collection wrote a book published around 2003. If you ask him about his own book, he will say "I wouldn't take much notice of that - most of it's out of date and a lot of the info has been updated with new science and discoveries. Some pretty pictures though.". In the days when many books/articles were written, they were done without the internet as a reference. People get bogged down looking for info on specific orchids. Try looking up 'cloud forests in S. America' - the places where they grow. Much better info on where they grow relating to climate etc than the info that would be obtained from looking up the individual species. There is a lot of incorrect info buried in some of the articles on the AOS site - they can't check every detail before it's included - it's just too big. My Miltoniopsis just about do ok, but they don't like the high temps in Summer and that's at 75% humidity with good air-flow. They would do much better if I could keep it down below 24C with a good drop overnight.
I take your point re old articles and books, although some of it must still be relevant. What got my attention in this case was that he was also a commercial grower of Miltoniopsis - and it's hard to argue with that kind of experience. Those daytime highs must have worked for him. Unlike scientific papers, orchid articles, whether in a book or published on the web, aren't 'peer reviewed'. They can only ever be a combination of experience, opinion and 'accepted practice'. To his credit though, he does point out that any amount of 'advice' can only be relevant to a particular micro-climate, and that very often it's the specific place it's kept in that will ultimately dictate its care requirements. There was no way I was ever going to get the kinds of temperatures he talks about - in actual fact my temperatures will more in line with what you're saying. That is, until mid summer or mid winter. I guess whether they thrive or die will ultimately depend on how tolerant they are. I may just have wasted a bit more cash - but what the heck! Interesting discussion though - thanks for your thoughts - always very welcome.
I guess I am kind of off topic but do anyone know of a good site to stream newly released series online ?
Hi Geoff,
I am quite firmly with Roger on both the books and the temperature range. The article says that 80-85f 26-29c is the top range and they generally die en mass in my greenhouse at those temps. I had quit trying to grow them for awhile as I realized that my greenhouse was much better suited to the upper end of intermediate to warm (so am I). Where I can grow them, and they thrive, is in my kitchen window!
Winter temps are 65f/18c to 70f/21c . My husband sets the air conditioning at 72f/22c in the summer, humidity sits right at 60% and gentle air movement from a ceiling fan. I have hybrid Miltoniopsis, Burrageaea, a Zygo hybrid and added a Miltoniopsis roezlii v. xanthina at the beginning of March. The thing is, I had to find the right place, in my conditions. If I remember correctly, you have not been through a whole year with this greenhouse? There are 12 packs of little thermometers/hygrometers, inexpensive but accurate enough to find the warm bright spots for Catts and Laelias and quantify the area where your Masde grows so well . If you have the time, and don't we all have extra time right now, sit and observe. You will find that spot that needs an extra layer of shadecloth or that vent that sticks a bit, or the cool,bright spot perfect for Miltoniopsis and Burragearas.
Thanks Lora - I don't disagree - I'm sure you're both correct regarding the temperatures. I've always maintained that 'rules' for plants are merely guidelines, and that microclimate plays a bigger role. However, I wouldn't dismiss out of hand anything written in a book, on the web, old or recent. Just as I wouldn't take them as 'scared laws' either. I think a good helping of respectful scepticism is always required with any information. It's great that we (as in plant folks) can discuss and debate these topics in an harmonious and helpful manner - something that other forums I've been on seem unable to manage.
My actual greenhouse temperatures will be much more in line with 21°C daytime highs - except - and this is where the Miltoniopsis might not cope - in mid summer and mid winter. I guess it'll depend on what its tolerances are. My Masdevallias and my Zygopetalum are both thriving so clearly they're not quite as fussy. I've just bought another Miltoniopsis so I'm hoping the little spot I've chosen for it is like Baby Bear's porridge. i.e. just right!😃
In tropical Aus, when we need to increase the humidity we use a sand pot. A pot, larger than the one the plant is growing in and then pack it with sand around the pot with the plant in it, so they are level. The sand holds onto moisture creating a more damp micro-climate around that single plant. A propagation heat mat would help with heat to an individual plant.
I've heard of standing pots in a wet gravel tray but that's a new one on me. Great idea - thanks for sharing it. I'll definitely give it a go once I need to ventilate the greenhouse to keep the temperatures down. 👍😁
@@Grow_Up_Man55 We got 40ºc this past February... those temps lasted a few days and I did lose a couple of plants but most came through it.
Wow! That's high! We'll be nowhere near that over here, but of course, my greenhouse definitely could get to those temperatures unless I act on it. Your humidity idea might save the day. 😀
@@Grow_Up_Man55 The tricks we use to grow our plants, should be shared rather than hoarded as it just may help someone else succeed - Happy Growing 🌱
@@j.d.8075 There are some wonderful old techniques that I fear are being lost. The pot in pot was how we started cuttings, sat in a saucer of water.
A very informative video. Just the sort of thing I enjoy. Hope all progresses well. Next to phrags, milts are my favourites. Thank you for your time.
Thanks - I'm really pleased you enjoyed it! 😀
The repotting looks good!
Let's hope so! Fingers crossed...👍
I have always wanted to try a Miltoniopsis. It sounds like they may grow near my Masdevallia area during the day and with my intermediates during the night. I will have to do more research. Thanks for sharing, stay safe
Sounds like a great idea, Patricia. I've just bought another one so I'm hoping this one will prove to like what I can offer it! 😀
I hope this pulls through for you 😃 I think these kinds of videos are very helpful! Personally, I do not grow them but I like seeing them on other channels .. thank you 😊
Thanks Nina. At least I'm being honest about failures. To quote Frank: 'Regrets, I've had a few...' 😂
Tropical Plants at 53 Degrees me too .. and that is what I appreciate about you 😃
Hi Jeff, good advice! I have killed a few myself, they do better now in tiny pots and finer bark, perlite and moss. I make sure to hide the pot in a mask because the algea would ruin my mix! Just to let you know, I just posted my first 6 videos for the #GVOS !
Thanks Anne, I appreciate it. I've also put a few into an outer 'skin' to protect from algae. And I like your GVOS videos - lovely plants! All very well grown - congratulations! 😁
@@Grow_Up_Man55 thank you , stay safe!
Hi Geoff, I have not grown these at all. I will be interested to see how yours make out. I may try one at some point. I hope this one recovers for you. Take care and be well!
Thanks Lucy - I hope so too - especially as I've just bought another one! 😂
I am a firm believer in annual repotting in the fall, and my miltonias and miltoniopsis started doing much better once i started using RO water instead of my tap water, which is surprisingly alkaline.
Thanks for the tip, Tracy - I appreciate it. I tend to use rain water anyway. I'm feeling optimistic...👍
I am not sure anymore in terms of watering when I hear 'water just before it gets dry'. Especially for miltoniopsis, this often leads to a situation where the plant is much too dry in between waterings. My miltoniopsis thrives, but always keep it wet (almost damp), and spray 3-4 times a week foliage + top of the pot. I use RO water (one week with light MSU formula, the other cycle with cleanwater only). Generally, I water each 10-12 days. My mix is 40% fine and medium Orchiata, 15% perlite and 45% moss. Top layer is covered with moss only. The orchid is kept close to a south facing window all year long, but I usually remove the plant from direct sun after 10 am and leave it 2 feet away from that window, in the shade, for the remaining part of the day. Foliage is healthy green, plant is making roots like crazy... bulbs are plump and the orchid blooms in the spring. I live in Canada and during winter, some days are very dry, this is why I keep my miltoniopsis +- two feet away from a cool mist humidifier working all day, but not at night. I also use a fan running at night and a few hours during daytime, if temperatures are above 20-22 C. I think most orchids can be finicky; sometimes we just need to start with a strong specimen, pay attention to its environmental needs and stick to a regular regimen. It' really worth the extra mile! 😉
Thanks for your input Thierry - some great tips there! 🙏 This is an old video in terms of my Miltoniopsis 'journey' to coin an overused phrase! I'm pleased you've managed to crack their care in your environment - and for me, that's the key - 'in your environment'. I don't think there is such a thing as the 'way to do it' as we all have such different microclimates. For me, I think mine simply weren't getting enough air around the roots so I'm trying coconut husks, which I'm told, hold onto water in a different way to bark and of course because of their shape, allow more air circulation. The jury is still out on whether the roots will thrive or rot. I got my most recent acquisitions through the worst of winter and they bloomed wonderfully early in spring - then took a nose-dive again - hence the experimentation with a new media. I agree totally that a strong specimen with plenty of roots to start with is important. But as for aftercare, it's very much a case of what works for one person doesn't necessarily work for another. I feel we've all got to try things in an intelligent and methodical way, then react to the outcome. Wish me luck!
You will get it right, I am sure. Sometimes we have to mess up with a few plants before understanding what works. Orchids need good care, but especially lots of observation. They almost speak to us... :) If we listen carefully, they can be the most rewarding plants!
I think the pure bark does not have enough aeration. I would add some chunky sponge rock or pumice or LECA into the mix. I think the center of a pot of pure bark mix stays too damp and stagnant. Just my 2 cents.
Thanks for the tip, I appreciate it! 😁
I wish you luck! They are so beautiful but temperamental 😁 I have successfully killed at least 4. The last 2 we're doing much better and growing new growths and roots, I was so happy then suddenly orange rot took them down in a few days. Strangely last year many youtubers lost them to orange rot... I found them happiest in a small, well draining pot with a mixture of bark, perlite and chopped spagnum and not burying the base of the bulb.
Thanks Bonnie - I've another 3 to go then! 😩 Sounds like I've potted them in the correct fashion - only time will tell, I guess. I'm expecting this one will revive up over summer but then winter will be the real test.
I am curious if this plant ever recovered. I've been looking for tips as i just got a miltoniopsis (and have killed one before). For me, the recommendation to keep roots evenly moist but at the same time not wet enough to rot is difficult to put in practice.
This is another of those very old videos - but no, this plant is long dead. To be honest, I discovered somewhat further down the line that most of my plants had spider mite, and it's only been the last few months that I've been able to get on top of them - so orchids, being the slow growers that they are, will be the last to recover. I strongly suspect many of my Miltoniopsis issues were down to mites. But like you say, getting the balance right between retaining moisture and drying out can be especially tricky for those of us with low sunshine days and months of low temperatures. Perhaps give coconut husks a try as it can hold moisture but has plenty of air gaps between it. Good luck!
I don't even bother growing them at all... Lol
Alas Todd, I've fallen under their hypnotising spell again and bought another of the pesky blighters...😂
I get my fine fir bark from chewy.com check it out!
Thanks Patty I definitely will! 😬
