Huge healthy plants, tons of flowers, no produce?

[journey11]

I am having issues with a lot of my garden plants. They are huge, healthy looking and green, and putting out a ton of flowers...but hardly any vegetables.

The cherry tomatoes I bought at Walmart are doing great with loads of fruits, but of 15-ish heirloom plants grown from seed, only one has made tomatoes, and not many at that. The plants are tall and blooming like crazy though...

My armenian cucumber (ONE plant!) is about two feet by five feet, 60+ flowers at any time, and is only making one cucumber.

The pumpkins and various squashes are growing well and blooming, but not making fruits.

Green beans are barely putting out anything...about 1-2 beans a day from over 100 plants.

I'm watering daily as it's really dry here (desert), and the soil has composted manure added to it from my own livestock. Leafy stuff like lettuce and chard have grown very well, just not anything that makes a fruit. Could it be the heat? It's between 80-110 here in the day and 60-80 at night. There's no shade anywhere and too big a garden to build shade over it all...

If your leafy vegetables are growing fast and your fruiting ones aren't producing a good guess would be that you have plenty of nitrogen but not enough phosphorus and potash.

This would be my bet too, especially since you mention leafy plants did well and you have lots of leafy growth....and since you have manure on hand.

Yeah, I'll update my stuff so you know where I am. I didn't realize I had not done so yet. I'm in zone 8, northwest Arizona. (Mohave County)

What gets me is that the Walmart bought tomatoes are growing great, with tons of fruit, and so are the volunteer descendants of my sister-in-law's Walmart plants which I dug from her garden, while my heirloom varieties look awful. The leaves are all wilty looking, even though I have had a shade cloth over them for 24 hours now and have watered them a lot. It's the tomatoes I'm concerned most about, since they take up so much of my garden space and are producing so little. I rely on this garden as my primary source of food.
