To keep hummingbirds healthy, change nectar every 2-3 days in hot weather, and every 4-6 days in cooler temperatures. Clean the feeder thoroughly each time to prevent mold growth.
Why Regular Nectar Changes are Important
Old nectar can ferment quickly, leading to mold and bacteria growth that can harm hummingbirds. Fresh nectar ensures the birds receive proper nutrition and stay healthy.
Signs It's Time to Change the Nectar
If the nectar appears cloudy, has debris, or smells off, it's time for a change. Regularly monitor the feeder and nectar to ensure it's clean and safe for hummingbirds.
