I recently cut the back bulbs off of my Chief Sweet orange and it has a shoot. I left the cutting on top of sphagnum moss. It was the part i made rootless and mounted. It grew 5 growths on the mount and I decided to dived the rootless backbulb off 4-5 growths. Awesome video!
Thanks for your comment - sometimes, sphagnum stays too wet and you will see the return of the rot. The better quality sphagnum moss may actually inhibit growth of the fungus. So, I am glad that this worked for you. Orchids are really very resilient - they can be abused and grow....
@plantpropagator I keep it with airflow so it tends to just be moist. Rapid wet dry cycles. You are right S.Moss will rot things. So far so good in this case.
Whoa! That actually would be cool if they leaves were naturally dark! Nice save! Brassavola hybrids always seem to be a little more forgiving in my experience.
I think that most orchids are forgiving - I do struggle with some species but, once they die on me, I usually do not try them again. Thanks for your comment
hey john, I recently mentioned that I used 4% bleach solution (40ml bleach per 100ml water) - although looking at those numbers that isn't even 4% lol anyway just wanted to say you were right, it need to be 6-10% But that is why 70% isoprpyl alcohol is probably best for black rot. Hydrogen peroxide takes much longer to be effective. Nice replacement you got though.
That bleach concentration is pretty high - it will certainly kill any organisms on the surface but will also kill any freshly cut plant tissue to a depth of a few mm (depending on how long you expose the tissue). Your concentration is 40% which is close to what I use on seed capsules because the bleach will not get to the seed in the enclosed capsule. I use 10% on isolated seed. Alcohol application is also topical and will kill any freshly cut tissue - but, it evaporates quickly. I just cleaned the tissue with water and then applied fungicide after drying, multiple times. Combatting black rot is a never ending battle!!~
@@plantpropagator I can see that happen when I cut open a green capsule using a blade straight out of disinfectant bleach solution, without rinsing. It works well and I can get the seeds out without any contamination, but the freshly cut green capsule tissue dies and turns black very quickly!
Thanks for sharing your lemonade! This video reminds me of a question I've had for a long time: It is a long held common knowledge that proper ventilation is essential to promote orchid health in the green-house, and failure to provide it can lead to disease, like black rot and others. But I don't understand exactly why, how does poor ventilation make the pathogen's life easier? Is it because it is good for the fungi and other pathogens, or is it because it is hard on the plant and weakens them? Do we even know why that is so? Also, I have saved many of my sick plants in the same way you do! I use crushed granite instead of Leca, but both are pretty inert and drain easy, which helps a lot.
Fungi like high humidity and the idea is that good ventilation keeps the humidity down and does not allow the spores to settle and germinatate. But, orchids mostly grow in high humidity so this idea is not quite right. I was out of town for almost 2 months before I saw this plant and it may have been heavily infested before the bougainvillea fell on it. I do know that orchids in certain spaces of my growing area are more prone to black rot and I isolate my plants and remove the infected leaves as soon as I see anything. I am always battling this disease!!
ruclips.net/video/mN1EQemHO7E/видео.html This is mix of an orchid specific fertilizer, a general fertilizer, epson salts and seaweed extract. I use this year round for all of my orchids and do not vary it - I do not have the time or patience to use different fertilizers on different orchids, depending on the time of the year... I hope that the video answers your question.
I was needing this video, right on time, thank you!😊

What fertilizer you use for your orquid?
