How to Make a Pea Trellis


Pea plants consist of shorter varieties, which typically grow no more than about 2 feet, and--less commonly--taller varieties, which usually grow up to about 6 feet in height. Regardless of what pea species you ultimately decide to grow, a trellis provides a support structure that makes harvesting less troublesome, especially for gardeners who have back problems. Go for a long, low trellis, which you can build in a single afternoon using an affordably priced livestock panel. Patricia Lanza, author of "Lasagna Gardening for Small Spaces," suggests that you plant a row of peas on either side of your trellis, locating the rows about 6 inches apart, to make maximum use of the trellis as a support for your peas.

Step 1

Purchase a single livestock panel and three steel T-posts for every 16 feet of pea plant rows that you want your trellis to support. For example, if you plan to have a 32-foot-long double row of peas, get two livestock panels and six steel T-posts. Look for the 16-foot-long livestock panels, which consist of a framework of stiff, intersecting horizontal and vertical steel rods, at your local farm and agriculture supply center. Opt for shorter "hog" panels if you have the shorter pea plants; go with taller "cattle" panels if you plan to raise some of the taller species of peas.

Step 2

Visualize an imaginary line straight down the center of your double row of pea plants. Sink one of the steel T-posts into the ground, locating it at one end of the imaginary line. Drive the post 9 to 12 inches into the ground with a handheld post driver. Measure 7 ½ feet straight down your imaginary line, and sink a second post 9 to 12 inches into the ground. Repeat this process to drive one more steel T-post into the ground 7 ½ feet from the second post.

Step 3

Lift the livestock panel with the help of a friend, and line it up with the three T-posts. Let 6 inches of the panel jut out from the two end posts. Wire the livestock panel to the T-posts with 6-inch strips of 14-gauge galvanized wire. Wrap one strip of wire around the T-post and the bottom horizontal steel rod in the cattle panel; wrap a second strip of wire around the T-post and the top horizontal rod in the panel. Space additional wires every 9 to 12 inches along the height of the panel. Repeat this entire process for each pea trellis that you need.

Tips and Warnings

  • Curve the ends of the wires down to minimize your chances of getting accidentally cut.
