Measure 1 cup of granulated sugar.
Combine the sugar with 4 cups of water in a large mixing bowl.
Stir the mixture until the sugar is completely dissolved.
If using, add a few drops of red food coloring and mix well.
Allow the nectar to cool to room temperature.
Pour the nectar into a clean hummingbird feeder.
Hang the feeder in your garden or balcony, preferably in a shaded area.
Monitor the feeder regularly and refill as needed.
Clean the feeder every few days to prevent mold.
Enjoy watching the hummingbirds visit your feeder!
