Quartet of Recently Acquired Neofinetia

[NYCorchidman]

As much as I hate hijacking someone's thread, since we started talking about the issue, here are my photos that are a few days old.

The first picture is of very poor quality but if you look very closely, there is that very thin black line where the newest leaf meets the next leaf.
This worries me more than the other because as I see this leaf today, it grew more and the dark area is all over!

The other picture, you can see the newest leaf having a black bar-shaped mark at its base.
This entire growth looks bad although you can't really tell in this picture. The leaves all look dehydrated.
something definitely not right.

Regarding water and mark, I do not believe that is the case because this particular plant is not sitting in the strong light and I mist everything everyday and never had spots, even the ones that sit nearly in direct sun.
So this worries me.
I have other neos but this is the oldest and the largest one with a nice flower show every summer. so I will be really bumped out if this one dies.
Buying a multiple growth neo is rather too expensive to me as they are priced per growth.
Oh, well... wait and see, I guess.

No worries in that regard, NYC! Leafmite offered a solution that might reduce the effects of these black spots. Based on your pictures, I still think it is a water related issue. Isopropyl Alcohol is some thing I have used in the past to stop the black spots from growing. I take a Q-tip and dab this alcohol on the underside of the leaf directly on the black spot. The alcohol will absorb into the blackened leaf material and dry it out.

Hopefully, that will work for you.

Well, I try alcohol dabbing.

I'm freaking out because I had lost neostylis Lou Sneary to something similar.
It was actually quite bad and fast.
I bought it in bloom with a multiple spikes. The plant was also a multiple growth one and I only paid about 20, so I was super excited.

Well, within one week of having it, a few leaves developed dark brown patches that grew fast.
I tosses the plant.

I was hoping I could tell you that is a "sumi" attribute but no. I've done the IPA dabbing successfully, too. I don't like that yours is at the crown, I'd do more than just dabbing in the area. Pry it open a little and douse it with alcohol. Keep it dry!

I'm not seeing anything troubling on the 2nd pic.

The black bar-shaped mark at the base of the new leaf.

NYCOrchidman, my Amami Hiroba has some black stripes on the underside of the leaves that look similar to that. I asked Kristen at NWO, and she said they were "ink spots" that some varieties get. I wonder if that's what you're noticing?

However, mine have not spread, so i think that could be concerning

[MattWoelfsen]

NYC, if you frequent eBay, when vendor "japaneseorchids" otherwise known as Seed Engei auctions off plants, the price is per plant, not per fan. On New World Orchid's website, they do list their plants for sale per fan.

This was very confusing to me when I first started collecting Neofinetia. But over time, I realized that I was getting a better deal when I bought my plants from the vendor selling per plant and not per fan.

BTW, if I was buying per fan, that means I am getting a division of a multi-fan plant, which is, in my humble opinion, a weakened plant when it arrives.

As I posted earlier, I am purchasing multi-fan plants like these four because in the Neofinetia world, "there is strength in numbers."

Wow, great looking, beautiful, juicy green fans. Your Neos look amazing!
I got two last month, and I think I'm getting hooked- for now I'm just excited to see them put out these beautiful red roots.

What is meant by "ink spots"? any dark spots that are not caused by diseases??

My plant is quite old and it had never had any black marks, sooooo I'm worried.

Who knew growing and shooting for specimen sized neo can be a pain? lol

Yeah, NWO was the place I think where I saw the plants were priced per growth.
I understand the value behind that because it takes time to grow more growths and as you say, bigger plants are stronger in general. Also, they get bigger and bigger much faster once hit certain size.

They also had quite a few varieties, but I am going to just enjoy the pictures and stay with my common white and pink varieties, oh, and hybrids. I love certain hybrids.

I haven't bought any from them, all mine are from local sources and great price at just $20 per plant. Luckily, all mine came with at least two or three fans, although only two of them have thus far flowered.
They are all now multiple growth plants. I guess they want to clump up some more.
Although mine are common types, they are seed grown, so I'm looking forward to a day when they all flower.

My biggest one gave me six spikes in the past two years.
I hope it continues on like that, but will see.

Hi all! I'm going to put my two cents in of experience.
These black spotting can be caused by many reasons... fungi, bacterial, sun, water, bites... I have used many ways to deal with them from IPA, fungicide, physan, hydrogen peroxide, etc... Sometimes they work and sometimes not. Then I tried aspirin spray. It seemed to work! At a dose of 325 mg uncoated aspirin (ASA) in 4 litres of RO water. Crush pill before adding to water to dissolve. Stir and shake regularly to suspend particles.
Protocol is as follows:
1. Spray hydrogen peroxide 3% on affected parts. Then Water entire plant with same esp medium. Let leaves dry 1-2 hours.
2. Spray entire plant with aspirin solution lightly on all sides.
3. Repeat every 3-7 days. Treat monthly if needed.

The ASA works indirectly to activate immune system of the plant as well as to halt pathogenic growth somehow.

Try and let me know!
