Light
Like most flowering plants, Easter Lilies prefer a bright spot to perform their best. They would prefer a spot protected from direct sunlight. Although they can survive in bright light, their lifespan will be shortened.
Keep in mind Lilies prefer consistent, warmer temperatures. So placing your plant in an area away from heat and air ducts will keep it happiest.
Water
Monitor the soil of your Easter Lily often. When the top of the soil is dry ot the touch, give your plant a thorough drink.
Fertilizer
Use a liquid house plant feritlizer every two weeks during the Spring and Summer for best results.
Transplanting in Your Garden
Once your plant has finished blooming and the danger of frost has passed, your can transplant it to your garden for more blooms in the summer. Remove all spent blooms and plant your Lily bulbs in the ground at the same depth they were in the pot. Insulate the roots with a layer of mulch. As the leaves start to brown, prune back, and watch for new blooms to start forming in June or July.
