Building a PVC bean trellis is not difficult but does require some planning. The trellis must be stout enough to support the plants and strong enough to weather high winds. It must also provide enough climbing surface to accommodate a high- production vine. Picking the beans can be difficult unless the trellis is designed with enough room to enter and maneuver when the beans are mature. Quick and easy installation at the start of the growing season and easy tear-down and storage with minimum space requirements during the off season are primary considerations.
Things You'll Need
- PVC pipe, 1 1/2-inch diameter
- Metal stakes, 3 feet long
- Plastic zip ties
Drive a metal stake or 3-foot length of re-bar at least one foot into the ground and at a 45-degree angle every five feet for the length of the bean row. Drive metal stakes into the ground in the same manner directly opposite the first stakes on the other side of the bean row. The stakes should extend from the ground at least two feet.
Use a hacksaw to score around the 1 1/2-inch, eight-foot-long lengths of PVC pipe, about 1/8-inch deep, every 12 inches.
Slide an eight-foot-length of the scored PVC pipe over each of the metal stakes to act as legs for the trellis.
Tie each of the joints where the two PVC pipes cross with a plastic zip-tie.
Lay a length of 1 1/2-inch PVC pipe in the V where the two PVC pipes cross on each row. Securely connect the length of horizontal PVC pipe with the two crossed PVC pipe on each row with plastic zip-ties. The length of horizontal PVC pipe should extend one foot beyond each end of the crossed pipes.
Hammer a metal stake vertically, at least one foot into the ground and extending two feet above the ground, at each end of the crossed pipes. Slide a length of PVC pipe over each of the two stakes.
Connect the vertical pipe at each end of the row and the horizontal pipe that lays across the V of each of the crossed pipes with a 1 1/2-inch PVC elbow joint.
Tips & Warnings
- Stout weather resistant cord can be strung from pole to pole to provide more room for beans to climb; however, this can make picking more difficult.
- Drive metal stakes at least one foot into the ground for a solid footing and two feet for very soft soil.
