In your zone you leave them in the ground and cover them with 2-3 inches of good mulch. But since you have already lifted them storing in peat moss is a good option.

I have only dug up one of them, so I could leave the rest in the ground. I thought that tuberose was only hardy to zone 8, though. Anyone else in zone 7 leave yours in the ground?

I am leaving mine in the ground and covering them deep with mulch. This is my first year at growing them so it is a trial for me too.

They are native to central Mexico, specifically Mexico City valley, and it can get quite cold on the outskirts of the volcanoes that surround and form the valley, yet they survive under those conditions.
