Leeks do ok in pretty solid cold which means that you can plant them much earlier in the year than other frost tender plants.

The last month that you can plant leeks and expect a good harvest is probably September. If you wait any later than that and your leeks may not have a chance to really do well. If you are starting your leeks indoors then you might be able to get away with starting them a few weeks earlier.
