The more light your lilies have the faster they will open,but the flower won't last as long if it is forced to open.

Asiatic lilies don't do well if the soil is too wet, so water them once a day early in the morning. This prevents fungal growth. Remove the petals that begin to wilt - this will encourage more flowering and less seeding.

Place the cut flowers in a bucket of warm water and leave in a warm area in the room
