My husband went over-board this year with squash / pumpkins / pickles / zuchinni .... and I made him swear that next year NO plants that extend beyond 6" beyond where they were planted! The vines were everywhere and it was a nightmare midway thru the season! Next year He is allowed a section of the garden for "viney plants" and we thought perhaps if its fenced, that anything over the fence gets lopped off! I have to admit we had a great haul this year, but the pickles were a failure.
I learned DON'T plant your Mega sunflowers (8' tall) as a natural fence / windbreak if you have something nearby that requires lots of sun. We had to use a machete to get to the beans!
