My narcissus bulbs won\'t grow. They are about two inches tall and won\'t grow any taller. I have had them in a small amount of water (just touching the bottom) for almost four weeks now. How can I make them grow. They are in a sunny diffused light window sill. Thank you, Karen
Forcing bulbs indoors requires a pretreatment with cold temperatures. If you just purchased the bulbs, ask the store if pretreatment was already done. If you are forcing paperwhites, check this webpage: https://www.gardeningknowhow.com/ornamental/bulbs/paperwhites/forcingpaperwhitebulbs.
