Off course. Any support you give them would be fine. The highest you
can give the better. However make sure it doesn't shade one side
contiually throughout the day! I have a friend who grows gurkins on a
wigwam support you described but built it upon a wheel that turns - the
result is that he can orientate the plants to the sun as he wishes.
