You do not have to boil water for hummingbird nectar, but hot water can help dissolve sugar and is useful when making extra nectar to refrigerate.
The safe sugar for hummingbird food is plain white table sugar. Keep the 4:1 ratio, skip dyes and alternative sweeteners, and refresh nectar before it spoils.
Use the 4:1 ratio for homemade hummingbird food: plain white sugar dissolved in clean water, served clear and changed often.
