Don't bother with "wigwams". Peas don't grow that tall. The best method is "pea-sticks". Basically, support sticks (about 3ft) and place them in the ground a couple of feet apart and then use string straight across. You will get more peas in a row. I use those plastic-coated green wire fences (they are about the same height as peas), peas attach themselves to that.
