Sweet-Nectar is made with a blend of steam-distilled floral hydrosols from flower species that hummingbirds visit the most - with added electrolytes and calcium - and no added color. Just add water to attract hummingbirds all summer. Pure cane sugar and added electrolytes deliver the nutrition and hydration hummingbirds require. Added calcium supports healthy egg development. Convenient pour-spout packaging makes it easy to fill feeders. Simply fill the feeder with one part Sweet-Nectar and two parts water. Made in the U.S.A. 1.5 L makes 4.5 L of nectar.
