Dendrobium Love Memory 'Fizz' arrived with yellow spotted leaves...is this normal?

[SJF]

I don't have experience with nobile type dendros. Is this normal, it arrived yesterday. I am worried.
Thanks in advance for your help

That's normal for this time of the year. My love memory fizz loses the pigmentation in its leaves before it drops them. I wouldn't be worried about it.

Thank you so much for your advice

Nope, it is not normal, but disease spots.
I just saw your other dendrobium. It only had one leaf affected, but this one looks bad.

What happens normally is that the leaves stay green until the cold weather hits, which causes nobile and related hybrids (and basically all other dendrobiums that need winter rest) drop their leaves.
The leaves will first turn yellow and then drop off.
Healthy leaves will have no marks or whatsoever.

I recommend removing any "dirty" leaves right away.
Usually that's the end of it. If you leave them on, you will see this again and again.

Even after you remove the affected leaves, keep an eye on the plant as the disease often returns.

Other than that, these are usually fuss free easy strong plants to take care of.

Thank you NY! I was hoping you would respond since I consider you a dendro expert. I sent the vendor pictures and he said it was perfectly normal senescence. It disappoints me that he wasn't honest. I suspected disease since that had previously trimmed one of the bad leaves.
Would you treat it with fungicide?

[NYCorchidman]

No problem!
Well, unfortunately, many people are not honest and even actively lying.

When I point out plants with disease, they usually say something like 'oh, that's just sun spots after being watered' or 'it's just nothing'.
They might assume I don't know anything about plants. lol
Now I just avoid bringing up the issue and simply just pass. hahaha

When the issue is bad enough, like your case with this particular dendrobiums, even people with any clue about plants or disease will be bothered looking at all those marks. Vendors know that, and that's why they simply cut off the most horribly affected leaves off to increase the market value of the sick plant.

That's the thing about online shopping. You don't get to see what you're getting unless it is on eBay with pictures.

For now, just remove the affected leaves and hope you won't see them again.

Even if you do spray, I recommend removing the leaves.
Also, when picking a fungicide for dendrobiums, do not use products with copper compounds.
It is advised that dendrobiums not sprayed with copper based fungicide.
