Choose feeders that allow you to see when the nectar becomes moldy and needs changing. Good feeders come apart easily and should be cleaned frequently. Sweet hummingbird solutions for feeders can either be bought or made at home. Some commercially produced solutions offer a formula with vitamins and minerals. Avoid solutions with red dye or flavoring.
Homemade solutions are much more economical and sometimes safer than store bought products.
A hummingbird feeder solution should contain no more than one part sugar to four parts water, the highest sugar concentration of most natural flower nectars. Boil one minute and remove from the heat. Cover the pot. Let the covered solution cool, then fill your feeder. Store the spare solution in a clean jar in the refrigerator for up to three weeks.
