A few thoughts... Was the weather hot this year? I know it's tough growing on concrete or blacktop, that usually makes matters worse. Also, maybe you had SVB problems... currently or in the past (growing in the same spot, they can hatch this year right under the plant.) It's hard to tell if it's SVB or bacterial wilt... bacterial wilt often takes down the entire plant... yours looks like just part of the plant. The fruit aborts can be heat related, especially since they are on pavement. I have a rear main vine on blacktop and no fruits set there, plus some leaves have crispy edges. The dried up leaves near the middle look similar to aged leaves near the beginning of a plant--they get that look from a combination of things--age, heat, wetting of the leaves during high heat, etc. I would look for signs of frass & holes in the vine section that's wilted, close to the stump. Also kinked or broken vines can cause the rest of a section of vine to wilt like that. See if you have any cucumber beetles in the flowers too. Hope this helps. Mark

Hard to imagine the black going away. Are you sure? As for the bugs, my guess is larval gnats. They can spread disease, but you only have two plants, far apart, so they may not be trouble at all. The problem with watering again is they like wet soil. My guess is the bark is a bit old and decaying already. Might that be possible? Do the pots have good drainage and don't stand in water? If all looks well, otherwise, live with the bugs for now, and when the plant is done blooming, repot it in new bark. Dump out all the old (outside, so the bugs go with it), wash off the roots in tepid water and put in new bark. Medium size. If the problem seems really bad, or is worsening, be brave and repot, even though the plant is blooming. When I get cheapos at trader Joe's, they are in spaghnum and I always repot the day I get them. It's never been a problem. The problem is the orchid addiction. I just watered the lot this AM and it took all morning!

Mine behaves the same. I think it's due to summer heat. Even daily weatering doesn't help the flowering.

It is a Phalaenopsis orchid and the leaves look fine. The blooms should last several months after they first open, perhaps the blooms were old when you purchased the plant. See if you can find some complete culture notes written for Greece. Read some of the many past Phalaenopsis threads on this site (put Phalaenopsis in the search box to find them)
