Start indoors early and transplant, or direct sow as soon as the ground can be worked. Parsley can take up to 2 weeks to germinate, so be patient and keep area watered. Thin to 12" apart for bushier plants. Harvest continually by cutting off the outer stems, leaving the middle leaves to grow. One planting can last all season, but it can also be sown in early summer for a fresh fall-winter crop.
