This year, in our experiment with hardscape (see Amish Ikea post), we constructed two parallel trellises for pole beans.  Even at over 6 feet high they weren’t tall enough, so, you may have guessed, we strung between the two for an arbor effect.

Stringing line between two trellises makes a pole bean arbor.

The effect is in full bloom.  It looks wonderful.
