Tulips are definately hardy for zone 6 but only certain types will repeat next spring. I doubt the potted ones are of that type.

Easter lilies are not as hardy as tulips. If zone 6 has a bad winter they may not make it even in the ground unless in a protected location. In a pot they will receive more chilling, lessening their chances of survival.

How to explain this? The 6" pot used for larger bulbs such as tulips, daffodils and lilies is not sufficient as a long term home. The soil is depleted and root growth was restricted. They need fresh soil most definately. And room for deeper root growth.

Thanks

Easter lilies often survive if planted out once weather moderates as far north as zone 4 or 5 sometimes, tulips and crocus may also. They will never bloom again for Easter since they were all specially forced into that schedule. Some will bloom in their normal season, some may refuse to bloom. All will take some time to recover from being forced out of season, and that may be a matter of years in some cases. Some may never recover. None of them will recover if not planted out from the pots they were forced in.

Ok.. how can I do it without planting in the ground. . I am currently not where I can plant in the ground. .. but hope to soon be

Make sure you mulch the lilies. They are actually pretty tough.
