Paperwhites That Won't Flop Over
Perfect Paperwhite Recipe
1 oz. gin, whiskey, rum or other 80 proof alcoholic beverage
7 oz. water
Mix liquor and water. When paperwhites have developed 2-inch stems, replace the water in which they are growing with the alcohol mixture.
Picture Perfect Paperwhites
What's one of the prettiest ways to brighten your home this winter? Force bulbs like "Ziva" paperwhites (Narcissus tazetta) to bloom indoors.
And what's one of the biggest drawbacks to forcing bulbs inside the house? Leggy flowers that droop, teeter and (sometimes) tumble onto the floor!
If you've been frustrated in the past by gangly paperwhites that topple over no matter how firmly you stake them or tie them up, don't despair. This year, you can grow picture perfect paperwhites with shorter stems that won't flop. How? Give your bulbs a nip of whiskey, gin, rum, tequila or other hard liquor.
The Secret to Perfect Paperwhites
Yes, that old wive's tale is true: alcohol really does cause paperwhites (and other bulbs) to produce shorter stems. According to experiments conducted by researchers at Cornell University, paperwhites forced in spiked water produce stems that are about 1/3 shorter than they would be otherwise. The trick? Applying the alcohol in the correct amounts at the appropriate time.
How to Force Picture Perfect Paperwhites
Experiments led by Cornell University's Flower Bulb Research Program Director William Miller show that the ethanol (alcohol) in hard liquor reduces the amount of water that cells within a developing bulb's stem can take in. The result? Shorter cells—and shorter stems.
To use liquor and water to grow shorter, sturdier paperwhites, follow the steps below. The process takes the same amount of time that regular forcing takes—about three weeks.
Plant bulbs in rocks & water.
Rather than force paperwhites in potting soil, arrange the bulbs (tip side up) in a container filled with clean rocks, and then add water. Fill the container until the water just touches the bottoms of the bulbs.
Add water as needed.
There's no need to place paperwhites in the dark or to chill them. However, you should monitor them, adding water as necessary to maintain the appropriate level. Soon, roots will form, and eventually the paperwhite bulbs will begin to sprout.
Replace water with liquor mixture.
When the bulb stems are about two inches tall, drain off the water and replace it with water laced with booze. The water should have an alcohol content of between 4 and 6 percent. If you're using gin that's 80 proof, for instance, you should mix approximately one part gin with approximately seven parts water.
Don't have any hard liquor on hand? No worries. You can use rubbing alcohol instead. Of course, if the alcohol content is greater than 80 proof, you'll have to dilute it more.
No Beer or Wine, Please!
Although hard liquor and rubbing alcohol mixed with water will produce paperwhites with pretty blooms and shortened stems, the same is not true of wine and beer. Both have a high sugar content which will interfere with the growth of your bulbs.
