If I were you, I would germ them in april next year...keep indoors until late may or june... dig some holes and backfill with good potting mix...leave the top an inch or 2 below the surface grade ...and put them outdoors in their holes right before it is supposed to rain for a couple days....I grew outties on the southeast side of chicago which is like 10 minutes from nw indiana...you can put them out as late as mid july and get 2-3 zips per plant..they won't get huge and noticeable .
