Q.About Peony Plants And Lily Bulbs
I ordered six peony plants from a company which I just received. Is there some way that I can winterize them because it snowed and I’m unable to plant them in the ground. Same thing with lily bulbs. My zone is 6. I need some advice. thank you in advance.

These are, usually, best planted in Autumn. They do enjoy the cold weather, but it may be a little too late to plant right now. Most of the time, long term storage doesn't do well for these tubers. You can make an attempt at storing with standard bulb storage technique, but they don't always make it. Storing them in dry soil, in container can be a semi-safe bet, as well.
