Squash can be pretty hearty and from my experience, the more you worry over it, the crappier it does. The more you ignore it the better it gets. I had some that started growing in my compost heap one year, I made squash for dinner and threw the guts of 3 of them into the compost, One butternut, one spaghetti, and the other, I can't even remember. I left it for a few weeks, then one day walked to throw more stuff in and it was covered with young squash. I said,well, looks like this is a squash heap this year, ill recover the compost next year.
It grew stupid crazy, and I made sure to water it every day bla bla, it was ehh.. most of them died off, wilty, etc, I got busy at work and evetually said the heck with this crap, im tired of babying it and it just dying off, it all can rot for all I care im gonna just turn the whole thing over and into the compost heap in a week, im DONE !!!
Well.. It got a squash on it that grew and grew and turned out absolutely delicious. Water it a LOT, it loves lots of water and sun, do NOT let it stand in water, make sure it drains well. It is very sensitive to drying out, but if you can catch it fast enough, wilty is recoverable. Otherwise, just ignore it. I had a lot of them just die on the vine, they'd go for about a week then just poop, off they went. I learned to ignore it, cut the rotten head off and the rest of it the chickie pooh's loved. I think I ended the season with like 9 or10 squashes out of the 3 of them, some I gave to my neighbor and he said they were absolutely delicious.
Of most the plants I have ever started from seed, squash has to be about the easiest to get started.
