Making your own hummingbird nectar is easy. Just mix one part regular white sugar to 4 parts water, heat the water to help the sugar disolve, then cool and fill your feeders.
For example, to make one quart of hummingbird nectar, heat 4 cups of water to near boiling, then remove from heat, and stir in one cup of sugar. Let it cool for several hours, until it is near room temperature and then clean and re-fill your hummingbird feeders.
I do not add or recommend adding any red dye to your hummingbird nectar, instead, use a red hummingbird feeder to attract the hummingbirds.
Make sure to clean and refill your feeders weekly, a little less often when it is cooler, a little more often during the heat of summer. You can also use a red dome over your hummingbird feeder, this helps keep animals like raccoon away, shades the nectar, making it last longer and if it is red, it will also help attract hummingbirds to your nectar hummingbird feeder.
