Concentrated hummingbird nectar that is free from artificial dyes and flavors. Carefully crafted to mimic the real flower nectar hummingbirds feed from in nature. Plus, the all-natural red color is derived from fruits and vegetables. Hummingbirds won't be able to resist stopping by for a drink. This concentrate makes feeding hummingbirds easy - just mix two parts water with one part concentrate and stir. There is no need to boil it. Any leftover nectar mixture can be refrigerated for up to two weeks. The resealable container not only allows you to use only what you need, but also keeps the remaining nectar fresh and ready for future feedings. Each concentrate bottle makes 96 ounces of nectar, ensuring an ample supply to attract and nourish hummingbirds. You can store unopened nectar for several seasons at room temperature. Over time, all-natural sugars in the nectar may crystalize. Simply use warm water to liquefy the crystals. The all-natural red color derived from fruit and vegetable extracts may fade over time, especially when exposed to the sun. If the nectar has faded inside of your feeder, that is an indicator it is time to refresh your nectar.
