Q.summer squash grows and flowers nicely, but no fruit.why?
both varieties of common summer squash(crooked neck and zucchini) are planted next to each other along the fence line. about 2-3 ft apart. Same spot used last year with nice production. No signs of disease or pest noticeable on stems or leaves. Perplexed, so I am thinking 10-10-10 today. thoughts?

Do NOT add something with high nitrogen, as you are planning.
That will only exacerbate the problem.
First, you will need to test your soil to see what, and how much of it is lacking. Usually this will be phosphorus, potassium, magnesium, calcium, and iron, along with pH adjustments that are needed.
Once you figure out how much you need, then you can correct it with what is deficit.
Usually, though, adding nitrogen when they don't produce fruit will only worsen the problem, as this is what normally causes the issue in the first place- Too much nitrogen, or not enough phosphorus and potassium (along with the other trace elements mentioned earlier).
