Harvesting
Plants can be reap in two ways : you could pull up entire plants and eat them like green onion , or you could snip off leaves as needed throughout the growing season , more like chives . Leaves will grow back quickly and can be foreshorten down several times throughout the time of year .
I choose to stick chiefly with the snipping method acting , pulling up only a few plants here and there once a piece is well established . This way , I can control that this hardy perennial continues to thrive and produce each year without any extra study for me !
