1. Start with a very clean vase. Fill it with fresh water; add one pack of the included cut-flower food to the vase.
2. Hold each stem next to the vase you plan to use to gauge how much you'll need to trim. Remove any foliage (leaves) that will fall below the waterline; submerged leaves rot and encourage bacteria that shorten bloom life.
3. Using a sharp knife, cut stem ends underwater at a 45-degree angle. This prevents them from sitting flat in the vase and allows for better water absorption.
4. Arrange flowers as you'd like.
Recondition lisianthius every two to three days: Recut stems, change the water, and add nourishment. Use the extra pack of food with your first water change. Keep flowers in a cool area out of direct sunlight. Although lisianthius have an exceptional vase life, the smaller unopened buds will never fully open.
