There has to be an optimum size. I would guess that a box that is too small
would end up being split apart from the pressure of the growing pumpkin,
unless it expanded out of the ends
I would still like to see photos when its completed.
I'm going to try again next year with a smaller box. I measured one of the
Red October pumpkins, they type I was trying to square, and the circumferen
ce was 25 inches. This implies a radius of 3.98 inches; a circle with that
radius would have an area of 49.74 square inches. If you fit that area into
a perfect square, the sides of the square would be 7.05 inches. My pumpkin
box has an inside dimension of 7.75 inches, so it was too big to square th
e pumpkin. I think that next year I'll make two boxes with an inside measur
e of 6 inches. The tops will be open, so that any excess will grow out of t
he top instead of bursting the box.
This year's box was made of 2 X 10 lumber, with the sides and bottom attach
ed with screws for extra holding power. Next year I'll use 2 X 8 and adjust
the sides so that the inner dimensions are 6 inches.
Pictures next year about this time.
I'm sure others discuss and might be better but it sounds like you no
not need that sturdy of a container. I've seen trees grow around small
obstacles and seen deer netting that even touches the plant stunt its
Makes gardening fun.
