How do I force paperwhite narcissus?
Paperwhite narcissus bulbs can be forced in clear, shallow bowls (no drainage holes) or pots.
When forcing paperwhite narcissus in bowls, partially fill the container with washed gravel or stones. Place the bulbs on the gravel or stones. Then place additional gravel or stones around the bulbs, leaving the tips (noses) of the bulbs exposed. Add water to the bowl until it touches the bottoms of the bulbs. Maintain the water at this level throughout the forcing period.
When forcing paperwhites in pots, partially fill the container with potting soil. Place the bulbs on the soil surface. Then add additional potting soil. When potted, the tips of the bulbs should stick above the potting soil. For ease of watering, the level of the potting mix should be half inche to one inch below the rim of the container. Water the potting soil thoroughly. Keep the potting soil moist throughout the forcing period.
Place the planted bulbs in a cool (50 to 55 degrees Fahrenheit), dark location for one to two weeks to encourage root growth. When the shoots reach a height of three inches, move the plants to a sunny window with a temperature of 60 to 70 degrees. As the plants continue to grow, staking is often necessary as the plants tend to be rather floppy. Flowering typically occurs three to six weeks after potting. When the paperwhites begin to flower, move the plants from direct sunlight to prolong their bloom period.
