Harvesting
In greenhouses, parsley matures 10 to 12 weeks after planting. The leaves must be pinched off the branch by branch, giving lots of grown stems behind to sustain the herb, while the crown proceeds to initiate further growth. Start by pinching the outside ones and continue working inward. Do not shave off the tips of stems as this will stunt further growth.
