Believe it or not pea plants do actually have a sense of touch. This response to touch or contact with a solid object, called thigmotropism, is what causes pea tendrils to coil. Here is how is works: when the tendrils feel the solid object, growth is stimulated in the side of the tendril opposite of the side of contact. The non-contact side of the tendril begins to elongate faster than the rest of the tendril, resulting in the coiling form we see on our pea plants.
So help your pea plants out by making sure they make contact with the trellis you have set up for them. We strongly encourage you to tie them up with garden twine throughout the season. Simply wrap string or garden twine around your tripod trellis or along the length of a net trellis (see photo).
If your peas do not find the trellis they will be more likely to break, mold, or become diseased due to lack of air circulation, so for the best yield guide them in the right direction!
Later in the season...
