Honey can develop a fungus which can be fatal to Hummingbirds. Keep the feeders clean and filled. Check them on a regular basisfor ants and other insects. It is also recommended that you mix only enough to fill the empty feeders. Storing the sugar water can also promote mold growth in the storage container.
Hummingbirds are very territorial.
Space your feeders out throughout the gardens so there is plenty of room for them to feed without conflict. Remember they burn up a lot of energy in flight, and chasing each other off the feeders needs to be prevented if possible. The following plants are the ones we decided to plant this year. We have used both annual and perennial plants in a good range of colors, heights, and blooming times. This heavy bloomer has dark purple blooms which appear almost black.
