Replant the forced narcissus in a large pot filled with well-drained soil that is rich in organic matter.
Apply a water-soluble fertilizer to the bloom according to the label’s directions. According to the University of Rhode Island Landscape Horticulture Program, forcing is a traumatic experience for the bulb, requiring the need for adequate fertilization.
Display the narcissus blooms in a cool area that is away from direct sunlight. The cooler temperature keeps the flower alive longer.
Create a mixture of one part 50-proof liquor, such as bourbon or vodka, and four parts water. Provide the narcissus plant with approximately 1 inch of this mixture weekly to keep it from growing too large and breaking under its own weight.
Cover the potted soil with a 1-inch layer of mulch. The mulch locks in the moisture and fertilizer, keeping your narcissus alive longer.
