CANE SUGAR: There are two sources of sugar: cane sugar and beet sugar, of which 70% of the world’s supply comes from cane sugar. Both are chemically “sucrose” and fall into the carbohydrate family. Carbohydrates are easily digested and provide the immediate “energy boost” that hummingbirds need to sustain their incredibly high metabolism.
1 part cane sugar/ 4 parts water ( no chlorine or fluoride) Measure and add sugar, at the rate of 1/4 cup of sugar to 1 cup of water. Boil the water first for about five minutes to kill bacteria and also burn off any chlorine. Let cool and store excess in refrigerator until ready to use.
Fill one-third of the container and be sure to change the mixture twice a week. You will need to clean your feeder every few days, with hot water and a mild (10%) bleach solution to inhibit bacteria/mold. Rinse thoroughly before refilling with water syrup.Or use what I use and explained below by our friends who create Feeder Fresh.
