Q.Why Would A Spaghetti Squash Plant Never Get Bloomes?
I have two plants that are big and growing like crazy for the past several weeks but not one flower, on either of them. Without flowers there obviously will be no fruit. Any ideas why? The cucumbers right next door have little cukes and flowers galore.

It is likely that there is not enough phosphorus and potassium in the soil to allow for blooming. It could be that the cucumber has used it all up before the squash could get to it.
A soil test will confirm. These articles will help:

Sounds like a possibility if it were not for the fact this area has only been used this year, never planted before, and is all new garden soil and compost. The plants are 5 feet apart and I do not think the cukes could have that much impact. I think, as was suggested on another site, that it is just a late blooming squash, hopefully. Or maybe all this unusual heat has the plant confused. Thanks for your suggestion, good to know for the future.
