The Last Crop?

 Glad I didn't misspell the title of this post :) I pulled these babies off the vine this morning, despite a frost last night. I have lots of green tomatoes left on the vine and I think we're going to make chutney again. I also have lots of leeks in the ground. Anyone know when I should pull these? They've been in since the ground defrosted and are still teeny weenie.  Leek experts needed!
