The Recipe
Homemade Hummingbird Food
1.Measure 1 cup white cane sugar.
2.Add 4 cups room-temperature water.
3.Stir until dissolved (no boiling).
4.Fill a clean feeder. Refrigerate extras up to 2 weeks.
Learning how to make hummingbird food at home takes about two minutes. You only need two ingredients — plain white cane sugar and water — combined in a strict 1-to-4 ratio. That's it. No food coloring, no preservatives, no honey, no special techniques.
The Sugar-to-Water Ratio for Hummingbird Food
1 part sugar to 4 parts water. This produces a 20% sucrose solution that closely matches the nectar found in real flowers. It is the ratio recommended by the Cornell Lab of Ornithology, the Audubon Society, and Smithsonian's National Zoo.
What Sugar to Use (and What to Avoid)
Use only plain white granulated cane sugar. It is pure sucrose — the same molecule in flower nectar.
Never use:
- Honey — grows fungus that can be fatal to hummingbirds.
- Brown / raw / turbinado sugar — too much iron.
- Organic cane sugar — also high in iron due to less refining.
- Artificial sweeteners — zero calories means starvation for a bird that burns its body weight daily.
- Red food dye — unnecessary and potentially harmful. Read more.
Do You Have to Boil the Water?
No. Tap water is fine in most areas, and white cane sugar dissolves completely at room temperature with stirring. Boiling can extend fridge life by a day or so — that's the only benefit.
How Often to Change Hummingbird Food
- Above 80°F: change every 2 days.
- 70–80°F: change every 3 days.
- Below 70°F: every 4–5 days is fine.
- Cloudy or moldy? Discard immediately and deep-clean the feeder.
How Much Hummingbird Food to Make
One batch (1 cup sugar + 4 cups water) yields about 5 cups of nectar — enough to fill most large feeders once with leftovers for the fridge. For a more detailed breakdown by feeder size, see our measurement chart.
Ready to Measure and Mix?
Making hummingbird food at home is easy — but it's also easy to forget to measure nectar across a full season. NectarBloom™ 2 lb is pure cane sugar to measure and mix at the 4:1 ratio: measure, mix, pour. Same recipe; use the feeder chart.
