The best time of year to attract hummingbirds to your garden depends on your location and the local climate. If you live in a warmer region, you can start putting out your hummingbird feeder as early as February or March.  Conversely, in colder areas, waiting until April or May to put out feeders is prudent, as it allows for the potential late arrival of hummingbirds and ensures that the feeders are available when the hummingbirds need them the most.
