Hi,
I am growing pumpkins in my garden. However, I had now idea they would take
over that much space.
Can you trellis the vines? Any pointers on how to get the plants not to
take up so much space??

Yes, they can be trellised. It must be a very strong trellis and you will need
to make shelves or slings to support the fruit. The downside is that the trellised
vines will not be able to root, making the whole plant more vulnerable to total
loss if the main stem is damaged by borers.
