I am trying to grow pumpkins and I was wondering if you have to grow it
on a hill like you grow most squash. What conditions do you need for
growing watermelon? Also, do pumpkins and watermelons grow in
Colorado?

Of course they grow in Colorado. Everything grows in Colorado. Just pay
attention to which zone you're in and plan accordingly.

Pumpkins are slow growing cold weather crop. They'll be ready for
harvest in the fall. Watermelon are warm weather fruit that should have
been started earlier and be already well under way (again, start only as
early as your zone allows). Also, read the info that comes with the
seeds/plants you plan to put in, and attend closely to approximated
harvest time, plant spacing, water use, and the anticipated length of
the vines.

Melons and pumpkins don't need to be grown "on a hill." They are planted
in hills, which are actually only mounds of cleared and graded soil as
wide in diameter as the particular plant is expected to spread. Plant
two or three seeds or starts in each hill, and don't thin them unless
they look ready to give up the ghost or show diseases.
