Okay, so I've grown herbs for the first time ever this year. I have Basil (which hasn't done too well), Chamomile, peppermint, spearmint, Lemon Verbena, and Catnip. I've been doing a continual harvest through the summer (taking a bit, letting more grow, etc), but now that fall is nearly here...do I do a "full harvest"? As in, cut them down to the ground? If so, when? We have a bit more warm weather on the way, but it'll end soon. I'm guessing I should take what I can before it gets too cold? As said, this is my first time growing herbs, so I'm still learning.
I'm from western washington.
