Answer: As the squash vines grow they will develop flowers along the new growth. I don't think caging will stop them from growing, flowering or setting fruit, depending upon the size of the cage. I've grown squash vines up a teepee style structure (3 bamboo poles set two feet apart in a triangle over the plant), guiding and tying the vines so they grow upright. You might try that if garden space is at a premium. It will expose the vines and the fruit to sunshine to help them grow and mature a little faster. Best wishes with your squash.
