No planting or watering required! These bulbs have all the energy and water in them to complete the blooming cycle.
Light isn’t necessary for blooming but is important for photosynthesis (making the stalks and leaves green). This will naturally happen in natural or synthetic light.
As the bulbs bloom, the water moves from the bulb into the stalks and flowers, making the bulbs top-heavy. As they bloom, they may require more support to be steady. Also, bulbs should be rotated to promote straight growth, if their light source comes from one direction.
