I have zucchini planted in a wine barrel. It produced 3 zucchini and now there are no more blooms. My cucumbers have tons of blooms, next to zucchini. The zucchini foliage was yellow, and I added some organic vegetable fertilizer. My husband says the wine barrels may be 'acidic'. Any suggestions on how to improve productivity?
If it is a problem of not getting any flowers, I would recommend adding some phosphorus to the soil. This article will help with that:
Can zucchini squash be grown indoors and produce fruit? Any tips?
It can, but your biggest challenge will be to provide enough light to it. You can use fluorescent lights set very near the plant to help bring it enough light to grow and bloom (and fruit) indoors. They also can take up a lot of room. If you are tight on room, you may want to look around locally for a community garden where you can rent a plot to grow vegetables in.
I am growing them in buckets in sandy loam. The pH is about 6.5.
This is typical behavior for squash plants, especially early in the season. They will produce mostly male blossoms, which fall off. Give it some more time and the plants should begin putting out female blooms.

My zucchini turns yellow mushy rot when about 4 to 5 inches long on the end of the fruit. They start out green. Not all fruit affected. I have harvested 6 full grown zucchinis. Please help, plants grown in containers.
They have blossom end rot. This article will help:
My zucchini and string bean crops are being grown on a deck in pots. Both have unique forms of brown spots, wilting dried out leaves and yellowing of the leaves. The string bean plants are producing beans, but the leaves are so spotted with browning. The zucchini leaves are yellow, have crisp brown edges but continue to produce beautiful zucchini at a slow rate. I have tried Neem oil, baking soda mixes and garlic mixes. Nothing works.
If the leaves were yellowing first, it may have started with a watering issue. Either to much or to little.
Stressed plants tend to invite insects or disease.
Neem Oil is my recommendation. You may want to reapply once a week.

We have a zucchini plant in a large flower pot. We started with a sprigging from a friend. It grew beautifully and produced 5 zucchinis, which we ate. Then all of a sudden the zucchini appeared on the plant as yellow, grew about one inch or so, rotted, fell off. Now we have no fruit at all, big beautiful leaves are turning yellow, but have flowers growing but they do not grow very large at all. Cannot figure out what we are doing wrong. This is the first time we have ever grown a zucchini plant. How sensitive are they to HOT weather in NC? Is it OK to water every time it gets droopy? Recently started watering twice a day due to leaves drooping. Has this been the correct procedure or have I drowned it? Please help!
It sounds like you are having pollination and watering issues.
When the flowers are not properly pollinated, the plant will reject the fruit while they are just a few inches long. For the pollination, you may need to hand pollinate. This article will help:
For the watering, I would recommend increasing the water. Many container plants tend to be underwatered, simply because people don't realize how much water is needed in the summer. Water at least once a day, 2X a day if the temps are over 85F.
My zucchini starts out nice and green. Then when it reaches 8-10 in, it turns yellow on the ends and narrows down. I have it in a well-drained container in potting soil. The only thing I added was some 15-15-15 spray.
This is blossom end rot.
