Hi gardenvt,
One thing the others will need to know to be able to help you is What kind of soil or mix are they growing in?

What kind of fertilizer and how often..

And maybe a little more info on how often you water.

JoJo

I use pro-mix & compost (2 to 1), all-purpose balanced fertilizer (like 10-10-10) every two weeks, and water daily in the morning. They are in a SW location with about 8-10 hours of sun a day.

I have three plants per 12 gal container and they don't seem rootbound.

I get that the yellowing can be caused by overwwatering or need of fertilizer. I also realize that if you let a cuke stay on too long the plant doesn't have much reason to keep producing as it has all the seeds it needs (so I have been told).

What I am particularly concerned about is the wilting regardless of whether it is wet or dry or just right. Hot, cool - doesn't matter.

I am growing Lemon (heirloom) and Diva (AAS winner)and both have the same issue though it is worse with Lemon and began with Lemon. I started some of each from seed, squirrels dug up the lemon a few days after I planted them in the container. I replanted but bought some just in case the ones I replanted with virtually no roots didn't make a come back. They did fine.

Is this a virus?

If so, can I use the same soil next year or do I need to toss it?

I love cucumbers and would really like to learn about how to grow them successfully.

Thanks for your help.

I'm also growing Lemon and Diva Cucumbers in both in-ground and Containers (SWCs). I've lost most of the in-ground crop (6 out of 8) to Bacterial Wilt from cucumber beetles, and #7 is showing signs of the disease. My container cukes are in a different location where I've only seen one or 2 Cuke beetles here, but I lost one this week to what appears to be Bacterial Wilt. I've also lost 3 in-ground Zucchini plants to the same thing, with a 4th showing signs.

Check your garden for Striped or Spotted Cucumber Beetles and take action to get rid of them. I'm going to try the 'red-dye' lure to control them. There is no cure for the plants once infected.

I've read that 'County Fair Pickler' cucumbers are very resistant to Bacterial Wilt, so I'll try some of those next year. It's probably too late in the season, but I'm starting a few Divas to see if I can get a late crop.

Good Luck

Here's a Striped Cucumber Beetle I found on my Zucchini:

Thanks ferretbee. This is exactly what my plants looked like. And I do think that I saw one of those things - I squashed it.

I have a Diva I planted a good distance from the others this past week and am hoping that I,too, can get a few more cukes before the season is over.

So, my other question was do I have to toss the soil from the containers? Also, does this affect tomatoes?

Is there a prevention method for controlling these beetles? Will Neem help?

Thanks again for your help.
