Hello, about a month ago I bought my first Monstera Adansonii from a garden center.
It was in a quite poor condition, since it might have got neglected over the lockdown. (yellow foliage)

When I got home with the little guy i removed the dead leaves and repotted it and fertilized it with some organic fertilizer.
So far so good, but a few days ago i spotted some weird leaves. some of them look marbled in shades of green, spotty and a bit translucent on some spots, also some of those leaves are wrinkly. In total there are around 6 odd looking leaves on a quite big and full plant. Also it still produces some new growth.

I really hope it just happend because of a nutrients deficiency or because of the tab water in my city.
But to be honest I'm quite afraid now that it might be mosaic virus.
I hope someone could give me a answer to my question.

Thank you very much

I have to admit it is a toss up....between nutrient deficiency and virus....but the very last photo does look a lot like mosaic virus

I tried to take some more pictures outside on my balcony, I hope its clearer to identify now.
In total its two leaves that look really crooked but I have to admit that the stems on this are really weak so I'm not sure if they are not just dying off, also "really suspicious" those are no new laves. Some more leaves seem a bit discolored, bur the newer growth seems bigger.

Also what would you suggest doing with it? Throwing it away or is it worth it keeping it quarantined and have an eye on it?
Also it touched a calathea and a photos since the three of them shared a table...I'm paranoid that I can throw all of them out in a few weeks.

Thank You!

I would do this....quarantine it and give it a good dose of a water soluble fertilizer like a 20-20-20 that also has trace elements and micro nutrients once a week for 2 weeks or so. Aroids that are not grown with a good nutrient regimen can suffer particularly from Manganese and Boron deficiency. Most fertilizers do not contain the trace and micros so you have to look for one that does. I have a huge bag of nothing but trace and micros that I add to basic water soluble. Things like Osmocote plus have them, but they are too slow release for this purpose. Another thing you might add is a top dressing of Dolomite. Dolomite is a limestone product that is very useful to aroids. A couple teaspoon full watered in every couple weeks. Many people who grow a lot of aroids mix the dolomite into the substrate when they pot up. If after a few weeks it does not correct this, or if it just continues to get worse, I would trash the plant. There is no treatment for this virus, and if it spreads to your other plants, it can cause the loss of an entire collection.

I have to say that some of the photos look like nutrient deficiency, but others really look like virus. If they were all just yellowing across the board, I would say definitely nutrient deficiency. But that patterning that looks like your plant is trying to suddenly become 'variegated' is a hallmark of virus.

Okay thank you very much! I will definitely try to fix it. Unfortunately I read on another page that there's a massive virus break out all across Europe, so I'm not too optimistic that's it it's nutrients.

What does that mean for my other plants that were in contact with it? Are they a goner too?

I would keep a close eye on them for sure but they are not automatically under a death sentence.
I have heard here as well in the US of people who have been getting importing plants from out of the country that have turned out to be infected. You have to be really careful where you buy from nowadays. I never import anything...if I can;t get it here from a nursery of get something from another trusted collector, I do without it. There are a lot of people selling plants off of pages on Facebook that they have imported. I don;t think they are all healthy all the time.

Mosaic virus is an increasing problem with Adansonii. The symptoms look enough like the virus, that I would not take a chance with it. There is no cure for the virus, so I would take the safe route and discard it. Even if it is not viral, those leaf discolorations are permanent so it will never look great.

You might also return it to the garden center not just to get a refund, but to advise them of the problem so they don't pass it along to other consumers.

Thanks to the both of you. You helped me so much also for my future plants Smiling


@WillC what's your opinion on my problem that the supposedly infected monstera. Is it very likely that my Pothos who shared a table with is also infrected?

I have a Hoya collection and i might have touched them after touching my Adansonii when I didn't know the virus. Is is common for Hoya to get infected?

Questions over questions. I'm still so shocked about it. Also I will inform the garden center as soon as possible.

Any plant can get infected as far as I know, but whether it kills them or not is another matter. Aroids for sure I would be careful with. But remember, there are many 'mosaic' viruses. Some don;t kill stuff, they make genetic mutations that cause variegation and stuff. The one that most commonly affects aroids is the Dasheen Mosaic. If any of the plants at the nursery look suspect when you go (look around before you speak up) if they look like yours, I would say that you should say something and ask for a refund. If they are virused the entire lot should be discarded

Viruses can spread to other plants but is probably unlikely in the instances you cited. No need to panic but do keep a close eye on your other plants for similar discoloration patterns. Crossing Fingers!
