Growing peas in containers is limited to bush types varieties of peas. If gardeners want to grow vine type pea plants, they will need to use a pea trellis of some type to support plants that may reach heights of 6 feet. If you want to grow vine types of peas such as English peas in a pot, then here are some ideas for trellising.
Pea Trellis Options
Chicken wire can be described as a mat of thin wire squares all woven together to make a grid about 4 feet high. Chicken wire usually comes in rolls and can be purchased at most building center, farm supply or garden center. If your pot is 24 inches in diameter, you will need a section of chicken wire that is at least 4 feet high and 6 feet long. Try to get wire that is 5 or 6 feet high. Begin by rolling the wire together to form a 18-inch diameter circle that is 4,5 or 6 feet high. Place the one end of the wire roll into the soil in the pot about 1-inch deep so the roll is sticking up out of the pot straight up. Now plant pea seeds around the outside of the chicken wire roll in the 2-inch ribbon of soil around the pot. You should be able to plant between 100 and 200 pea seeds.
This is a slightly unusual but artistic way to trellis peas using tree branches. Take a walk in some nearby woods or park if you live in the city and look for forked tree branches about 6 feet tall. Want you want are branches that have as many forks as possible. Hawthorn, birch and even some ornamental bushes will have suitable branching. You will about a dozen branches for a 24-inch pot. Insert the non-branched end of each branch about 12 inches into the soil about 3 inches from the inside edge of the pot so the forked branches are parallel with the edge of the pot. Repeat this, spacing the branches equally around the pot. For added strength, you can tie some of the forked branches together at the top. Plant between 100 and 200 pea seeds about 1-inch below the surface of the soil all around the inside perimeter of the pot.
