Answer: Because your Easter Lily has been living indoors for a while, you'll want to gradually acclimate it to outdoor growing. Continue to water as usual and when the weather warms, take it outside a set it in a shady area. After it has set outdoors in the protected spot for 7-10 days, you can plant it where your other lilies are planted. It will probably lose its foliage while it's in the pot. When that happens you can stop watering until it goes into the garden bed.
Best wishes with your garden!
