Orchidee Disidratate: cosa fare? – Dehydrated Orchids: what to do? [eng. subtitles]

Hello everybody! welcome back this video is in italian as you probably already realized as it was requested by two fellow italian youtuber they talk about orchid too and if you are interested, I’ll put a link to thier channel In this video I want to talk about dehydrated orchids because recently I had a positive experience and I thought it may be a useful video to many people Recently I got two seriously dehydrated orchids This is one of the two, it’s a Maxillaria porphirostele a botanic species of Maxillaria and as you can see now it isn’t dehydrated at all and that’s because I wanted to do this video. Dehydration in orchids may be caused by two main reasons Wrong waterings (not enough water in quantity or frequency) Or some problem at the roots system, For some reason the root system doesn’t work, it was damnaged and so the roots aren’t able to sustain the hydric necessities of the plant. It is not always easy to understand the cause of the dehydration expecially if you are in a season like this (winter) when is better not to disturb the plant to check the roots. There is a simple and effective method to understand what caused the dehydration What I did whit this plant and the other one, the Coelogyne (I will put a link to the haul video where you can see them as they arrived) is simply to soak the pot in water putting the pot in another container filled with water till the edge of the pot in order cover all the media. In this case, with very dehydrated plants, I left them soaking for a night, but even a couple of hours may be enough. Doing this, the media completely soaks in water and if the roots are healthy, the water will be carried from the media to the pseudobulb, in the case of the Maxillaria and the Coelogyne. If instead the root system is not in a good shape the plant will remain totally or in part dehydrated. In this case we can go on and control the roots taking the plant out of the media and start to think about different possibilites to try in order to save the plant At this moment I don’t have many plants in this condition (not enough roots or damnaged roots) just the one you see in the corner. But I can assure you that I had plenty of them in the past! In this case it is a Cattleya hybrid It was in a terracotta pot but apparently I did something wrong and it had lost part of the root system (the healthy roots are form the most recent vegetation) And as you can see the older pseudobulbs are starting to suffer for the absence of roots and so for the absence of water What I did in this case? I unpotted, cleaned the plant from the media as much as possible and in this case I could have just repotted straight away with new media as it hase some healthy roots But I waited first because I wanted to show it in this video, second because I want to keep it under control. The simple thing I did was to place it on a pot with some sphagnum moss that I keep slightly humid in ordeer to keep a minimum of humidity avoiding a further dehydration. The current low winter temperature helps me in this, in summer it would be more difficult and I should even spray the plant with water to keep some humidity on the leaves. As I said in this case I used some sphagnum but you can use different materials like bark, gravel, lapillus… Another method to keep more humidity around the plant is to create a “micro-environment”. I tryed this a couple of time with a good percentage of success. For example, this is a plant that I saved with this method, it had lost all the roots and it was summer (temperatures above 30°C expecially in central months) What I did with this plant: I had a big glass jar, I treated the plant with fungicide, I put in the jar some humid sphagnum, the plant and I closed it. In this way the humidity around the plant was constant and it stopped the plant from a further dehydration (that would have debilitated even more the plant) The plant managed to produce a new vegetation (I think the first was this one) and new roots. Last year it managed to flower for the first time since the hecatomb. So, create a closed micro-climate around the plant with a jar or even a plastic bag And before that, I recommend a treatment with fungicide and anti-rots just because, being a closed environment without air circulation, molds and fungi may proliferate quite fast. So, recapping: in order to understand why a plant is dehydrated (wrong waterings or root problem) it is sufficient to sunk the plant in water for some hours or more. If the plant recovers in the following days (obviously the necessary time varies between single cases) the problem would be waterings-related, the root system must be quite healthy. If the plant doen’t recover it’s good do check the roots and act accordingly, following your instinct if you like, or with the two methods that I have experienced with success. One last thing, not all the plants that looks dehydrated aren’t necessarily so, and a typical example is the common yellow Oncidium: in this case (this is my yellow oncidium plant) the dehydration of the old pseudobuld is normal for this variety so you don’t have to worry about it! Well, it’s all for this video! I hope I didn’t forget anything if I did I’ll put it in the description. If I understend how to put the subtitles you should have read them I hope to succeed, I never did that before! And that’s all, I hope this video will help you, Remember to give it a thumbs up, subscribe to the channel And I will see you with the next video! Ciao! 🙂
