Decrease the amount of sugar concentration in the food after a couple of weeks. Doing this will increase the activity at your feeder. One part sugar to five parts water or one part sugar to four parts water will dilute the mixture. When the mixture is more diluted, the hummingbirds have to come back more often.    Do not make the mixture any weaker than 1 part sugar to 5 parts water. If the food has less sugar than this, the hummingbirds will expend more energy flying to and from the feeder than they will be able to replenish by eating the food. You want to make the food strong enough that you do not constantly have to fill the feeders, but not so strong that the birds visit infrequently and you don't get to see them. Making food that is incredibly high in sugar will give the hummingbirds a high amount of energy, allowing them to go longer before eating again (so they won't be visiting your feeder as much.) If you have tried different mixtures but there are still no hummingbirds using your feeder, plant flowers that will attract hummingbirds. Here are plants that hummingbirds like: Bee Balm, Phlox, Lupine, Hollyhock, Red-Hot Poker, Columbine, Coral Bells, Foxglove, Cardinal Flower, Lantana, Salvia, Butterfly Bush, Rose of Sharon, Trumpet Vine, Trumpet Honeysuckle, Crossvine, Carolina Jessamine, Indian Pink (Spigelia).
