how do I know when to harvest my leeks?
Hi there, I am a relatively new kitchen gardener, and this is my first time growing onions, leeks and shallots. I understand that the onions and shallots are pretty self explanatory, and I think I've got them covered, but I'm a little confused on the leeks. They don't seem quite big enough to harvest yet, but I'm not sure of what the harvesting indicators are. And what are scapes? I've read about them on other postings, but I really don't seem to grasp what they are. Any help would be appreciated.
