As blossoms wither and leaves yellow, remove them. Change the water and fresh flower food solution, if the water gets cloudy. This also helps preserve the fresh lily fragrance of your arrangement. However, lilies require only about half the dosage recommended for other flowers. Flower Arrangements A classic lesson of flower arranging suggests that young buds and tender pointed leaves be placed at the top of an arrangement and that larger, more dominant flowers be placed at the bottom.
Lilies are dynamic enough to carry an arrangement all by themselves.
However they also mix well with other flowers. Even one lily stem can dress up an arrangement of more modest flowers. Lilies should be placed centrally in an arrangement, preferably in the lower two-thirds. And, as they are fairly large, heavy flowers, larger containers often work best.
