I'm trying to grow pumpkins, but they're doing the same exact thing as last year. They're blooming, then the flowers fall off leaving a blank stem. I bought new seeds this year thinking maybe it was because I was using old seeds. Last year all squash related plants were a bust. Two years ago, I had incredible squash plants and ended up with more than we could consume. I don't know what changed - other than I didn't plant as many varieties as I had that year I had too much. This year, because I was so busy with the chickens, I only planted pumpkins, no squash.
