Hopefully you can get some blooms soon! The winter blooming Clowesia are spiking now and the spring blooming Catasetums (e.g. tenebrosum) should bloom in a month or two!
Oh wow! That would be interesting seeing how you twist it's growing season around! Thanks for taking us along! Yes the Edema is interesting too! Wonder if Bernie or Fred has any clue what causes it? Some years I have it bad, others not at all. Weird 🤷♀️
Thanks for showing the bumps on the leaves. My Cyc coopers and Cyc Richard Brandon both have it at about the same amount as yours. None of my other Ctsm types have it at all. It doesn't seem to bother them, they grew and flowered just fine. I have no idea what it is, I'm just glad that I'm not alone. Lol
It’s a surprisingly common issue for this group and I can’t seem to find an answer for what causes it! The plants seem to grow and flower just fine though!
I own several Catasetum, Clowesia and Cycnoches. Of them, only the Cycnoches develop the same edema on their leaves. I inspect the leaves very closely, and there are no pests. Same as you. I am so clueless! Please let us know if you find a cause. Also very eager to know how you will acclimate that Cooperi guy. Thank you for your videos.
I would have expected the roots to be quite a bit larger given the advanced stage of the growth. Hopefully you can get it plumped all the way back up before you have to force dormancy.
I was also thinking the same. However, the new growth was pretty big when I got it, so I bet the first flush of roots died during transport and this is the second flush of roots.
The Adema is an odd thing that happens intermittently to me as well. I moved all my Ctsm into New Zealand crushed tree fern this year with great results. More water retentive and good air down in the roots. Less adema as well
I had always assumed the edema was pest-induced, but, like another commenter, never saw any pests. The fact that it's not in the center also goes against the pest theory, since even though the top of the center is hidden, the bottom is exposed. I'm amazed that you've gotten that much growth without watering/ feeding. Mine usually dessicate if I let them go that long. But your watering from the bottom trick probably supports it without affecting the new roots.
Yes, keeping high humidity at the roots is really important to preventing desiccation! I’m wondering if the higher humidity contained within the pleated leaves helps prevent the edema? Not sure yet though!
Thanks for the information! The Missouri Botanical Garden is having its orchid show at the end of this month and I'm hoping to find something of this type there.
when i grow my pepper seedlings indoors during the winter they tend to get oedema if I don't have a fan on them- especially the ones I was growing in "kratky" hydroponics. typically increasing ventilation will force the plant to transpire more and relieve the issue. for some reason your plant isn't opening its stomata enough to breath, but that can be caused by a complex mixture of various factors when it comes to orchids, compared to something like a pepper plant.
@@SVKLOrchids probably something like that. orchids stomata opening and closing is very complicated compared to other plants because they can do multiple types of photosynthesis and have a lot of adaptations to try and survive drought given their vulnerabilities as epiphytes. orchids under prolonged water stress can take a long time to start transpiring normally even if the water returns. since you mention this plant likes humidity its probably not opening its stomata because it doesn't trust that water will be available given the conditions its being kept in. just my 0.02 / theory. i've noticed that water stressed cattleya seedlings, for example will take a LONG time to restart growth if they are dried out for too long even when ideal conditions return.
Well that is doing awesome! And I must be lucky enough that the Cooperi I got a month before you doesn't have any Adema and is still doing fine growing slowly here and get allot of cool cloudy days... and I am going to do the same thing with mine so I will be following right along with you Buddy!🤣🤣 I wish mine was as big as your's but oh well 🤷♀️ BUT my Mormodes revolutum is HUGE and gorgeous and on time for the dormant period coming up with a lovely new growth!!

@@SVKLOrchids Thanks a lot for your reply Stephen. If you don't have seeds, and as it is the gift seasons, it will be great for seedlings and bulbes. Also, thanks for sharing the contact in Germany. Will contact her. Bon dimanche. Daniel
Good luck with it, looks like it’s off to a great start. I’ve not yet had the edema issue in 4 years of growing these types. I am bewildered by the extent of the condition..wow. Just another orchid making us scratch our heads … 😅
This is definitely the most extreme example I’ve seen! Usually it’s just a few bumps here and there. Gotta love the orchid mysteries that make us go down rabbit holes! 😂

Great video as always Stephen! About that edema, I had quite a bit show up this year in my collection (13). This is my first year growing 12 different types of catasetinae AND growing in coco peat. I rinsed the coco peat prior to using then dried it. What crossed my mind is whether the edema was caused from a calcium/magnesium deficiency since I did not do the 'buffer' step advocated by cannabis growers using coco peat. They seems to be more info from cannabis growers out there than orchid growers on this topic of cal/mag lock out due to the high ratio of potassium (if i was understanding them correctly?!) I understand you predominately use cypress mulch, but I wonder if there is a relation of some kind with the cal/mag thing when it comes edema... strength of cell walls and all that? Potassium issue? I remember watching Paula @hillbillyorchids preparing coco chunks for use with orchids, doing repeated soak rinses prior due to high salt content of coco chunks, then doing the cal/mag buffer soak. Thanks again Stephen! 🙏🙂
I agree, these changes may be due to the lack of an optimal ionic balance of Ca2+, Mg 2+ and K+ for this orchid. I once read that the reason for this may be excess water, but it is unlikely.
@@SVKLOrchids Changes on the leaves cause an increase in leaf surface area and increase the plant's ability to transpire water. Whether this also causes a change in osmotic pressure in cells caused by an increase or decrease in the concentration of Ca2+, Mg2+ and K+ (in cells) cations is difficult for me to determine. But as you can see, it does not affect the growth of the orchid.
Thanks!
Thank you so much!
I am still struggling with blooming Catasetum types… but less were killed last year. 🎉 thanks to you. Now if they only bloom this year…

I’m not sure, honestly! But not watering or fertilizing the plant might mean that it’s not a nutrient issue, but I’ll dig around and find out.
