I never had luck with these plants. I tried many times when I grew in NY. I have not tried them in Florida.

If the plant was in a box for days this might have encouraged a fungal growth. Heat, dampness? I don't know whether the box was open or closed.

The spots look fungally to me. Try spritzing the spots with diluted alcohol or even wipe them with a cotton ball.

How are the roots? Has it been kept damp in the box?

It was shipped from Ca along with seven other plants. The other plants are all OK. I did wipe the leaves down with alcohol yesterday. Figured if no one could offer ma a better solution, I'd wait three/four days then wipe with peroxide.....trying to hit both bacterial or fungal. I hate watching a plant go downhill and not know how to get the situation under control

Zygos are particularly susceptible to leaf spotting. I would love to hear how other control the spots.

Well I have about 15 zygos. They're pretty reliable little guys. However I agree on the spots. Typically I'll wipe them with peroxide if there's only one or two. Otherwise I cut the entire leaf off. Lately I haven't had any trouble at all (knock on wood). They do appear to like to be on the damper side but we're very dry here and it's hard to keep up with the watering in the house. In the winter, they're kept inside in those mini-greenhouses you can get for about $40 when they're not blooming and that helps quite a bit. In general dryness gives me far more issues than any wetness. I can even keep the bottoms of the pots sitting in a small amount of water-like I have to do with the two phrags I've got. Right now I've got a very nice Zygonesia MurasaKikomachi blooming. Sadly, someone knocked off an entire spike before bloom but the other two spikes are still putting out well-even in winter. Smells really nice!

There's nothing special I do to keep the spots off; I can even tell you that they're a little crowded in the greenhouses. This spring I'm going to take a bunch of the smaller ones and pot them together. They should be fine and it will reduce my watering chores!

I also put them outside in a shaded area all summer too-they appear to like it.

Best,

I have same zygonisia too! Generally zygos don't like dryness. May be zygo in question just dryed out? I bought one no ID zygopetalum once and changed medium to bark as soon as I brought it home. It was big mistake! All leaves dried out and only one pseudobulb survived. However, I didn't give up and that one bulb started new growth. Three years later plant has three bulbs, two leaves, no blooms. But I nursed it back to health, so, I'm not giving up!
