Making hummingbird nectar requires water, sugar, a whisk or spoon, a clean saucepan and a hummingbird feeder. Mix four parts water to one part sugar into the saucepan over low heat, and stir until the sugar dissolves.
The mixture does not need to boil unless the water needs to be purified. If it boils, the ratio of water to sugar changes. Once the sugar dissolves, the mixture has to cool or it will crack or warp the feeder. If it is only enough for one feeder, place the mixture into the refrigerator for at least 15 minutes to cool it down. Do not add ice, or else the mixture becomes too watery to attract hummingbirds.
Once the mixture is cool, pour it carefully into a clean feeder. If any is left over, store it in the refrigerator for a few days before it spoils. The color red attracts hummingbirds, but adding red dye to the mixture is not necessary if any part of the feeder or any of the nearby flowers are red. Place your hummingbird feeders in shaded areas, and thoroughly clean them every three or four days to keep the nectar from spoiling and to avoid mold growth that can kill hummingbirds.
