My winter squash vines are growing by inches, or more, a day. They have topped my arbor and lots of fruits are setting. The Waltham butternut do best on an arbor since the vines are long and flexible.

I have five butternut plants growing on the left side of the arbor and, on the right side, four plants of different varieties: Hubbard Blue Ballet (a small fruited hubbard, whose vines are a challenge to train up an arbor as they are so thick), Orange Kabocha, Buttercup, and Delicata (this small vine has been overrun by the other three very vigorous ones).
