Winter hummingbird feeding can help resident birds and late migrants, but the nectar stays simple: the 4:1 ratio, clear solution, no dye, and a freshness routine you can keep.
You can freeze fresh 4:1 hummingbird nectar in clean, sealed containers, then thaw it in the refrigerator and use it promptly.
Homemade 4:1 hummingbird nectar lasts up to about one week in the fridge when stored covered and clean, but it should be discarded sooner if it turns cloudy, smells sour, looks stringy, or shows mold.
Store homemade hummingbird nectar in a clean, covered container in the refrigerator and use it within about one week.
Use this temperature-based schedule for fresh hummingbird nectar, plus the signs that mean the feeder should be emptied and cleaned right away.
