japanese toad lily planting
got some today (since last ones compy sent failed to do anything) and as i've planted these before in numerous locations with no success, I'd like some advice. how deep do you plants the roots for starters. I've planted them in shade, semi shade, loamy soil,dryer soil, under a pine tree so a bit more acidic soil, and so on. any help would be appreciated before i put these into the ground for the winter.
