Will my squash plant fruit alone...?

Many thanks for your recent enquiry regarding the butternut squash plant you have. Squashes are members of the cucurbit family and have separate male and female flowers on the same plant (with the exception of certain types of greenhouse cucumber); so the answer to your question is no – one plant is enough to produce the butternut squash.  

You can hand-pollinate your squash plant to help speed things along a little; simply remove a male flower (it won’t have a tiny squash growing at the bottom), pinch off the petals and push the flower, complete with pollen-laden stamens, into a female one.
