I wanted to know if summer squash and butternut squash are planted next to each other in the garden, will they cross-pollinate?Last year my wife and I grew some zucchini and yellow squash close together and we had some green-yellow squash and so on. They were very delicious, but we weren't sure about the butternut squash. Please help. Thanks, farmerdad
Two different types of squash can cross pollinate, but you would not see the effects of this until you planted the seeds from the fruit of the cross pollinated plant. The plants grown from the seeds of the cross pollinated plant would produce the results of that cross pollination.
I have a large area in my yard that is covered with gravel. I filled my garden spot and still have plants left to be put into the ground. I'm wondering if I can clear some spots in the gravel to plant watermelons, butternut squash, and acorn squash. Would the gravel make the plants too hot?
I would recommend placing them in a rasied bed. These articles will help: https://www.gardeningknowhow.com/edible/fruits/watermelon/growing-watermelon.htm

Is it better to pollinate your butternut squash with a paint brush or let it do so naturally?
Unless you have pollination issues already, you can just let nature take its course.
I have planted butternut squash seeds too close to each other, and now they are quite big healthy plants. Am I too late to re-plant in a bed with more space? Will it kill them?
As long as they are healthy and growing vigorously, I would let them be. Moving them now will only cause more harm than good.
What would make butternut squash rot on the vine while still very young? The flower is still attached to the fruit.
This could be from blossom end rot or poor pollination. These articles will help: https://www.gardeningknowhow.com/edible/vegetables/squash/squash-blossom-end-rot-causes-and-treatment.htm

My husband picked eight butternut squash that are definitely not ripe, as they all have green stripes on them and are not the tan color they should be. Is there any way I can ripen them so we can eat them? Are they okay to eat now? Our cellar has a dirt floor, very damp, dark and humid. Would that be a good option to store them there or should I put them in the sun to ripen? I am confused by the various answers. Thanks.
I would not put them in the damp basement, as this will encourage them to rot. This article will help with ripening them:

Will butternut squash continue to ripen after harvesting in early August?
It depends on if it is to the ripening stage. There is a turning point when the squash is green where it will continue to ripen if it is picked after this point. There is no good way to tell if a squash has reached this point if it is all green, but if you were starting to see some color, then you should be able to finish it. This article will help:
