Pea shoots are tender and taste sweet and mild like fresh peas. Harvesting a few pea shoots won't harm the vines' growth, but actually encourages more branching, potentially producing more peas for you to harvest later.
When plants are a few inches tall, select 2"-4" shoots from the top of the plants and pinch them off using your fingernails or scissors, leaving at least one set of true leaves on the plant (see illustration below).
Assuming you don't snack on them right in the garden, add them to a salad or use them in a stir fry. They're even a tasty addition to sandwiches, tacos, or as a garnish with other vegetables (such as steamed carrots).
Or try this delicious recipe from Botanical Interests: Pea Shoots with Garlic.
In just two to four weeks, you will be eating fresh shoots!
You can even harvest a crop two or three times. I encourage regrowth by misting the plants with a weak solution of Espoma GROW! Liquid Organic Plant Food mixed with tap water in an All Purpose Spray Bottle.
