Ooh, I'm so excited. I can see my little pea seedlings poking their heads out of the soil. I can hardly count the days until they are ready. Get out the butter!
Lately in catalogs and garden centers I've noticed more and more pea trellis apparatuses, (or is that apparati?) for supporting the treasure-laden vines. Some are flat, some are tilted, some are arched, but all are pretty pricey.
I've always made my own pea trellises from bamboo poles and zip ties. They end up looking sorta cottage/sorta Asian. A little wonky. Whatever, they do the job.
For each trellis buy one bundle of 4' bamboo poles. They're sold 8-10 in a bundle for around $3-$6. Lay down an old blanket or paint cloth on a flat surface and arrange the poles in a grid. Leave more space at the bottom so those ends can be pushed into the soil to hold the trellis in place.
I bind the poles where they cross with small black zip ties. See the photo below. Work on the edges then inward. The poles may want to twist a bit but you can adjust this when you're done. Trim the off the excess plastic when you have the pieces all in place. Watch out, the edges can be sharp.
Adjust for your pea plant spacing and then push into the soil. I use galvanized u-shape pins to anchor them in place since my garden is exposed to wind along that side of the house.
Well at least the snow makes the trellis easier to see!
Now all you have to do is wait for your peas to germinate, climb the trellis and fill their pods! That's the hardest part.
