Ready to use 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. Convenient ready to use formula is easy for you, and just right for hummingbirds. Simply pour the nectar directly into your feeder. There is no need to mix it with water or boil before using. 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. The 64-ounce bottle will keep you in good supply through many visits. 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.
